Having knowledge and skills above and beyond the basics of your field can give you a professional advantage. Here are eight ways to keep your job skills and knowledge up-to-date.

1. Take Professional Development Courses:

Professional development courses can help you expand your professional skill set, learn something new, or even earn academic credit to put towards a degree. Online training courses are particularly convenient because they are affordable and flexible. Just be careful to do your homework—evaluate instructor bios, read reviews, and check the syllabus carefully before putting down your credit card. You can also find professional development courses through vendor-taught classes, traditional universities, and training institutions.

2. Use Online Resources:

The Internet is a limitless source of free information and educational resources. Attend educational webinars, follow the blogs or social media accounts of industry experts, or bookmark and regularly check industry news sites and online forums to stay current on the latest trends. If you haven’t already, sign up for news alerts for your inbox (Google Alerts works well) or set up an RSS feed like Feedly.com to easily put all of your industry news in one place.

3. Attend Professional Events:

Professional events are valuable ways to learn about growth and development in your industry. Local companies, business associations, and professional groups often host seminars, forums, or workshops that can give you direct access and insight to experts in your profession. Treat these events as constructive networking opportunities to brainstorm and share ideas with colleagues who can provide fresh insight and perspective.

4. Network Online:

As an independent consultant, you know the importance of building and maintaining a list of contacts to ensure a steady flow of work. Use LinkedIn to connect with high-ranking people at companies you’re interested in working with. Employ social media platforms to promote your own service or brand, network with industry experts, and keep in touch with former and current clients.Start by finding which social site works best for you—connect with fans and followers on Facebook, creatively network and share news on Twitter, or utilize blogging to boost your online credibility, and connect with potential clients.

5. Invest in Continuing Education and Certifications:

While continuing education and certification programs typically require a more intensive time and financial obligation, they can help boost reliability, and demonstrate a commitment to your profession. Becoming proficient in a new software platform before it becomes mainstream, committing to upholding industry standards through a certification program, or staying on top of market trends by taking a class can increase your income and position you competitively within your line of business.

6. Follow Thought Leaders on Social Media:

Social media platforms have given thought leaders a new outlet for sharing valuable information, insights, and practical advice. Seek out and follow both industry leaders in verticals you specialize in and those who specialize in skill areas you have or want to build. By reading regular posts, you can not only gain additional knowledge, but you can also build relationships by commenting and reacting to posts and increase visibility of your business and skills by sharing their content.

7. Read White Papers and Case Studies:

Top companies, consulting organizations, agencies, and think tanks regularly publish white papers and case studies on industry trends and often offer them for download at no cost. Stay up to date on industry and business trends by taking advantage of these resources.

8. Determine Hard and Soft Skills to Develop:

Conducting a self-assessment to determine your hard and soft skills and target those you want to develop should be a core activity in your professional development. A self-assessment test such as CliftonStrengths Assessment will measure your natural ways of thinking, feeling, and behaving, and you’ll get access to personalized reports that help you better understand what makes you unique and how to use your strengths to reach your full potential.Maintaining enhanced knowledge and skills in your field shows clients you are well informed and dedicated. Set yourself up for success by investing in your job skills and knowledge today.

Why Best Friends Are Important?

Friends… All of us have them, but sometimes we don’t realize how essential friends are and take them for granted. However, don’t forget best friends improve our lives. They make our lives better and provide a lot of benefits. Do you know the true value of your best friend? If you don’t, read this post carefully until the end.

1. A best friend makes you smile for any reason, or even without a reason

According to recent studies, having a close friend around can lift your mood very quickly. You actually know what it’s like to feel stomach aches because your pal is making you laugh so hard! Besides, it means that every time your friend makes you smile, he/she makes your thoughts more positive and makes you a happier person.

2. A best friend makes you stress-free

Scientists showed that your true friend can reduce stress and make you feel better if you’re tense. You feel comfortable when your friend is around. This person creates your comfort zone and, thus, spending quality time with him/her helps you decrease stress levels.

3. A best friend allows you to be yourself

When you’re close to your friend, you know you can be yourself. Your best friend knows everything about you – everything bad and everything good. So, it doesn’t really make sense for you to pretend.

4. A best friend gives you effective constructive criticism

Who else will be totally honest with you if not your best friend? The person who knows you best. He/she knows your strengths and weaknesses and can find suitable words to tell it like it is. Sometimes your close friend is the person who knows you even better than you do yourself and he/she isn’t afraid to tell you things you don’t want to tell yourself.

5. A best friend helps you grow

Your true friend boosts your personal growth because you both share experiences. It can be very useful for you as when you’re stuck in a rut, it’s cool to hear what other people are doing. Therefore, your close friend is a powerful stimulus to your development.

6. A best friend is always ready to listen to you at any hour of the day or night

When you’ve got a best friend, you’ve got a person who can always listen to you if you want to talk about something. Moreover, you realize that you can share anything with your close pal because everything stays just between you.

7. A best friend shows you the right direction

Having a real friend to share things with helps you learn new things about yourself. The things and thoughts your friend shares can not only open your eyes to new ideas but also can show you the right direction you have to move on.  

8. A best friend gives you a sense of confidence

The person you consider your best friend recognizes the value you contribute to the world and helps you understand how great you are! In such a way, you become more confident… as well as more self-confident.

9. A best friend reduces your risk of illnesses

Your best friend is the person who also has a positive effect on your health (mental and physical). Your close pal helps you fight your diseases and when you feel his/her support it’s easier for you to handle any illness.

10. A best friend extends you a helping hand in every situation

A best friend is always ready to share not only your good times but also help you in tough times. Your real friend stands by your side no matter what. This is the person who wipes your tears when you cry, supports you when you fall, generally offers the shoulder to cry on and encourages you if you’re down.

The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax). The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopic.

The bronchioles eventually end in clusters of microscopic air sacs called alveoli. In the alveoli, oxygen from the air is absorbed into the blood. Carbon dioxide, a waste product of metabolism, travels from the blood to the alveoli, where it can be exhaled. Between the alveoli is a thin layer of cells called the interstitium, which contains blood vessels and cells that help support the alveoli.The lungs are covered by a thin tissue layer called the pleura. The same kind of thin tissue lines the inside of the chest cavity — also called pleura. A thin layer of fluid acts as a lubricant allowing the lungs to slip smoothly as they expand and contract with each breath.

Lung Conditions:

Chronic obstructive pulmonary disease (COPD): Damage to the lungs results in difficulty blowing air out, causing shortness of breath. Smoking is by far the most common cause of COPD.

Emphysema: A form of COPD usually caused by smoking. The fragile walls between the lungs’ air sacs (alveoli) are damaged, trapping air in the lungs and making breathing difficult.Chronic bronchitis: Repeated, frequent episodes of productive cough, usually caused by smoking. Breathing also becomes difficult in this form of COPD.

Pneumonia: Infection in one or both lungs. Bacteria, especially Streptococcus pneumoniae, are the most common cause, but pneumonia may also be caused by a virus.

Asthma: The lungs’ airways (bronchi) become inflamed and can spasm, causing shortness of breath and wheezing. Allergies, viral infections, or air pollution often trigger asthma symptoms.Acute bronchitis: An infection of the lungs’ large airways (bronchi), usually caused by a virus. Cough is the main symptom of acute bronchitis.Pulmonary fibrosis: A form of interstitial lung disease. The interstitium (walls between air sacs) become scarred, making the lungs stiff and causing shortness of breath.

Pulmonary fibrosis: A form of interstitial lung disease. The interstitium (walls between air sacs) become scarred, making the lungs stiff and causing shortness of breath.Sarcoidosis: Tiny areas of inflammation can affect all organs in the body, with the lungs involved most of the time. The symptoms are usually mild; sarcoidosis is usually found when X-rays are done for other reasons.Obesity hypoventilation syndrome: Extra weight makes it difficult to expand the chest when breathing. This can lead to long-term breathing problems.Pleural effusion: Fluid builds up in the normally tiny space between the lung and the inside of the chest wall (the pleural space). If large, pleural effusions can cause problems with breathing.

Pleurisy: Inflammation of the lining of the lung (pleura), which often causes pain when breathing in. Autoimmune conditions, infections, or a pulmonary embolism may cause pleurisy.Bronchiectasis: The airways (bronchi) become inflamed and expand abnormally, usually after repeated infections. Coughing, with large amounts of mucus, is the main symptom of bronchiectasis.Lymphangioleiomyomatosis (LAM): A rare condition in which cysts form throughout the lungs, causing breathing problems similar to emphysema. LAM occurs almost exclusively in women of childbearing age.

Cystic fibrosis: A genetic condition in which mucus does not clear easily from the airways. The excess mucus causes repeated episodes of bronchitis and pneumonia throughout life.Interstitial lung disease: A collection of conditions in which the interstitium (lining between the air sacs) becomes diseased. Fibrosis (scarring) of the interstitium eventually results, if the process can’t be stopped.Lung cancer: Cancer may affect almost any part of the lung. Most lung cancer is caused by smoking.Tuberculosis: A slowly progressive pneumonia caused by the bacteria Mycobacterium tuberculosis. Chronic cough, fever, weight loss, and night sweats are common symptoms of tuberculosis.

Lung cancer: Cancer may affect almost any part of the lung. Most lung cancer is caused by smoking.Tuberculosis: A slowly progressive pneumonia caused by the bacteria Mycobacterium tuberculosis. Chronic cough, fever, weight loss, and night sweats are common symptoms of tuberculosis.Acute respiratory distress syndrome (ARDS): Severe, sudden injury to the lungs caused by a serious illness. Life support with mechanical ventilation is usually needed to survive until the lungs recover.Coccidioidomycosis: A pneumonia caused by Coccidioides, a fungus found in the soil in the southwestern U.S. Most people experience no symptoms, or a flu-like illness with complete recovery.Histoplasmosis: An infection caused by inhaling Histoplasma capsulatum, a fungus found in the soil in the eastern and central U.S. Most Histoplasma pneumonias are mild, causing only a short-lived cough and flu-like symptoms.

Hypersensitivity pneumonitis (allergic alveolitis): Inhaled dust and other substances cause an allergic reaction in the lungs. Usually this occurs in farmers or others who work with dried, dusty plant material.Influenza (flu): An infection by one or more flu viruses causes fever, body aches, and coughing lasting a week or more. Influenza can progress to life-threatening pneumonia, especially in older people with medical problems.Mesothelioma: A rare form of cancer that forms from the cells lining various organs of the body with the lungs being the most common. Mesothelioma tends to emerge several decades after asbestos exposure.Pertussis (whooping cough): A highly contagious infection of the airways (bronchi) by Bordetella pertussis, causing persistent cough. A booster vaccine (Tdap) is recommended for adolescents and adults to prevent pertussis.Pulmonary hypertension: Many conditions can lead to high blood pressure in the arteries leading from the heart to the lungs. If no cause can be identified, the condition is called idiopathic pulmonary arterial hypertension.Pulmonary embolism: A blood clot (usually from a vein in the leg) may break off and travel to the heart, which pumps the clot (embolus) into the lungs. Sudden shortness of breath is the most common symptom of a pulmonary embolism.Severe acute respiratory syndrome (SARS): A severe pneumonia caused by a specific virus first discovered in Asia in 2002. Worldwide prevention measures seem to have controlled SARS, which has caused no deaths in the U.S.SARS-CoV-2/COVID-19: The coronavirus that led to a worldwide pandemic beginning in 2019 can lead to pneumonia that affects both lungs, filling them with fluid and making it difficult to breathe. COVID-19 can lead to long-term lung damage and other respiratory conditions such as acute respiratory distress syndrome. Pneumothorax: Air in the chest; it occurs when air enters the area around the lung (the pleural space) abnormally. Pneumothorax can be caused by an injury or may happen spontaneously.

Lung Tests:

Chest X-ray: An X-ray is the most common first test for lung problems. It can identify air or fluid in the chest, fluid in the lung, pneumonia, masses, foreign bodies, and other problems.Computed tomography (CT scan): A CT scan uses X-rays and a computer to make detailed pictures of the lungs and nearby structures.Pulmonary function tests (PFTs): A series of tests to evaluate how well the lungs work. Lung capacity, the ability to exhale forcefully, and the ability to transfer air between the lungs and blood are usually tested.

Spirometry: Part of PFTs measures how fast and how much air you can breathe out.Sputum culture: Culturing mucus coughed up from the lungs can sometimes identify the organism responsible for a pneumonia or bronchitis.Sputum cytology: Viewing sputum under a microscope for abnormal cells can help diagnose lung cancer and other conditions.Lung biopsy: A small piece of tissue is taken from the lungs, either through bronchoscopy or surgery. Examining the biopsied tissue under a microscope can help diagnose lung conditions.Flexible bronchoscopy: An endoscope (flexible tube with a lighted camera on its end) is passed through the nose or mouth into the airways (bronchi). A doctor can take biopsies or samples for culture during bronchoscopy.

Rigid bronchoscopy: A rigid metal tube is introduced through the mouth into the lungs’ airways. Rigid bronchoscopy is often more effective than flexible bronchoscopy, but it requires general (total) anesthesia.Magnetic resonance imaging (MRI scan): An MRI scanner uses radio waves in a magnetic field to create high-resolution images of structures inside the chest.

Lung Treatments:

Lung TreatmentsThoracotomy: A surgery that enters the chest wall (thorax). Thoracotomy may be done to treat some serious lung conditions or to obtain a lung biopsy.Video-assisted thorascopic surgery (VATS): Less-invasive chest wall surgery using an endoscope (flexible tube with a camera on its end). VATS may be used to treat or diagnose various lung conditions.Chest tube (thoracostomy): A tube is inserted through an incision in the chest wall in order to drain fluid or air from around the lung.Pleurocentesis: A needle is placed into the chest cavity to drain fluid that’s around the lung. A sample is usually examined to identify the cause.Antibiotics: Medicines that kill bacteria are used to treat most cases of pneumonia. Antibiotics are not effective against viruses.Antiviral drugs: When used soon after flu symptoms start, antiviral medicines can reduce the severity of influenza. Antiviral drugs are not effective against viral bronchitis.Bronchodilators: Inhaled medicines can help expand the airways (bronchi). This can reduce wheezing and shortness of breath in people with asthma or COPD.Corticosteroids: Inhaled or oral steroids can reduce inflammation and improve symptoms in asthma or COPD. Steroids can also be used to treat less common lung conditions caused by inflammation.Mechanical ventilation: People with severe attacks of lung disease may require a machine called a ventilator to assist breathing. The ventilator pumps in air through a tube inserted into the mouth or the neck.Continuous positive airway pressure (CPAP): Air pressure applied by a machine through a mask keeps the airways open. It is used at night to treat sleep apnea, but it is also helpful for some people with COPD.Lung transplant: Surgical removal of diseased lungs and replacement with organ donor lungs. Severe COPD, pulmonary hypertension, and pulmonary fibrosis are sometimes treated with lung transplant.Lung resection: A diseased portion of the lung is removed through surgery. Most often, lung resection is used to treat lung cancer.Vasodilators: People with some forms of pulmonary hypertension may require long-term medicines to lower the pressure in their lungs. Often, these must be taken through a continuous infusion into the veins.Chemotherapy and radiation therapy: Lung cancer is often not curable with surgery. Chemotherapy and radiation therapy can help improve symptoms and sometimes extend life with lung cancer.

Chambers of the Heart:

The heart is a muscular organ about the size of a fist, located just behind and slightly left of the breastbone. The heart pumps blood through the network of arteries and veins called the cardiovascular system.

The heart has four chambers:

The right atrium receives blood from the veins and pumps it to the right ventricle.

The right ventricle receives blood from the right atrium and pumps it to the lungs, where it is loaded with oxygen.

The left atrium receives oxygenated blood from the lungs and pumps it to the left ventricle.

The left ventricle (the strongest chamber) pumps oxygen-rich blood to the rest of the body. The left ventricle’s vigorous contractions create our blood pressure.

The coronary arteries run along the surface of the heart and provide oxygen-rich blood to the heart muscle. A web of nerve tissue also runs through the heart, conducting the complex signals that govern contraction and relaxation. Surrounding the heart is a sac called the pericardium.

Heart Conditions:

Coronary artery disease: Over the years, cholesterol plaques can narrow the arteries supplying blood to the heart. The narrowed arteries are at higher risk for complete blockage from a sudden blood clot (this blockage is called a heart attack).

Stable angina pectoris: Narrowed coronary arteries cause predictable chest pain or discomfort with exertion. The blockages prevent the heart from receiving the extra oxygen needed for strenuous activity. Symptoms typically get better with rest.

Unstable angina pectoris: Chest pain or discomfort that is new, worsening, or occurs at rest. This is an emergency situation as it can precede a heart attack, serious abnormal heart rhythm, or cardiac arrest.

Myocardial infarction (heart attack): A coronary artery is suddenly blocked. Starved of oxygen, part of the heart muscle dies.

Arrhythmia (dysrhythmia): An abnormal heart rhythm due to changes in the conduction of electrical impulses through the heart. Some arrhythmias are benign, but others are life-threatening.

Congestive heart failure: The heart is either too weak or too stiff to effectively pump blood through the body. Shortness of breath and leg swelling are common symptoms.Cardiomyopathy: A disease of heart muscle in which the heart is abnormally enlarged, thickened, and/or stiffened. As a result, the heart’s ability to pump blood is weakened.Myocarditis: Inflammation of the heart muscle, most often due to a viral infection.Pericarditis: Inflammation of the lining of the heart (pericardium). Viral infections, kidney failure, and autoimmune conditions are common causes.Pericardial effusion: Fluid between the lining of the heart (pericardium) and the heart itself. Often, this is due to pericarditis.Atrial fibrillation: Abnormal electrical impulses in the atria cause an irregular heartbeat. Atrial fibrillation is one of the most common arrhythmias.Pulmonary embolism: Typically a blood clot travels through the heart to the lungs. Heart valve disease: There are four heart valves, and each can develop problems. If severe, valve disease can cause congestive heart failure.Heart murmur: An abnormal sound heard when listening to the heart with a stethoscope. Some heart murmurs are benign; others suggest heart disease.Endocarditis: Inflammation of the inner lining or heart valves of the heart. Usually, endocarditis is due to a serious infection of the heart valves.Mitral valve prolapse: The mitral valve is forced backward slightly after blood has passed through the valve. Sudden cardiac death: Death caused by a sudden loss of heart function (cardiac arrest).Cardiac arrest: Sudden loss of heart function.

Heart Tests:

Electrocardiogram (ECG or EKG): A tracing of the heart’s electrical activity. Electrocardiograms can help diagnose many heart conditions.Echocardiogram: An ultrasound of the heart. An echocardiogram provides direct viewing of any problems with the heart muscle’s pumping ability and heart valves.Cardiac stress test: By using a treadmill or medicines, the heart is stimulated to pump to near-maximum capacity. This may identify people with coronary artery disease.

Cardiac catheterization: A catheter is inserted into the femoral artery in the groin and threaded into the coronary arteries. A doctor can then view X-ray images of the coronary arteries or any blockages and perform stenting or other procedures.Holter monitor: If a doctor suspects an arrhythmia, a portable heart monitor can be worn. Called a Holter monitor, it records the heart’s rhythm continuously for a 24 hour period.Event monitor: If a doctor suspects an infrequent arrhythmia, a portable heart monitor called an event monitor can be worn. When you develop symptoms, you can push a button to record the heart’s electrical rhythm.

Heart Treatments:

Exercise: Regular exercise is important for heart health and most heart conditions. Talk to your doctor before starting an exercise program if you have heart problems.Angioplasty: During cardiac catheterization, a doctor inflates a balloon inside a narrowed or blocked coronary artery to widen the artery. A stent is often then placed to keep the artery open.Percutaneous coronary intervention (PCI): Angioplasty is sometimes called a PCI or PTCA (percutaneous transluminal coronary angioplasty) by doctors.Coronary artery stenting: During cardiac catheterization, a doctor expands a wire metal stent inside a narrowed or blocked coronary artery to open up the area. This lets blood flow better and can abort a heart attack or relieve angina (chest pain).Thrombolysis: “Clot-busting” drugs injected into the veins can dissolve a blood clot causing a heart attack. Thrombolysis is generally only done if stenting is not possible.Lipid-lowering agents: Statins and other cholesterol (lipid) lowering drugs reduce the risk for heart attack in high-risk people.Diuretics: Commonly called water pills, diuretics increase urination and fluid loss. This reduces blood volume, improving symptoms of heart failure.Beta-blockers: These medicines reduce strain on the heart and lower heart rate. Beta-blockers are prescribed for many heart conditions, including heart failure and arrhythmias.Angiotensin-converting enzyme inhibitors (ACE inhibitors): These blood pressure medicines also help the heart after some heart attacks or in congestive heart failure.Aspirin: This powerful medicine helps prevent blood clots (the cause of heart attacks). Most people who have had heart attacks should take aspirin.Clopidogrel (Plavix): A clot-preventing medicine that prevents platelets from sticking together to form clots. Clopidogrel is especially important for many people who have had stents placed.Antiarrhythmic medications: Numerous medicines help control the heart’s rate and electrical rhythm. These help prevent or control arrhythmias.AED (automated external defibrillator): If someone has sudden cardiac arrest, an AED can be used to assess the heart rhythm and send an electrical shock to the heart if necessary.ICD (Implantable cardioverter defibrillator): If a doctor suspects you are at risk for a life-threatening arrhythmia, an implantable cardioverter defibrillator may be surgically implanted to monitor your heart rhythm and send an electrical shock to the heart if necessary.Pacemaker: To maintain a stable heart rate, a pacemaker can be implanted. A pacemaker sends electrical signals to the heart when necessary to help it beat properly.

Your relationship with yourself is just like any other relationship: It requires commitment, time, and effort. It’s important not to neglect your relationship with yourself. If nurturing yourself doesn’t come naturally, try these five ways you can practice self-care and give yourself some love.

Replace criticism and comparison with acceptance and appreciation.

Try to be aware of when you begin to criticize or compare yourself to others. When those thoughts come, stop and think of something you like about yourself, or simply repeat a self-love mantra such as, “I am enough. I love and respect myself.”

Communicate with yourself in kind and positive ways.

Self-talk has a big impact on how you feel about yourself. Ask yourself how you would communicate with someone you love, care about, and admire, and then try to incorporate that communication style into your internal dialogue.

Show respect for yourself by setting boundaries and prioritizing your needs.

While helping others is a good thing, the demands of family, work, school, friends, and others can become overwhelming. Practice saying no sometimes so you can avoid putting yourself under too much pressure. And try not to feel guilty about it: you can’t take care of others unless you also take care of yourself.

Spend quality time with yourself.

Every relationship benefits from quality time. Learn to appreciate your own company by taking time to do things that feel good and make you happy. Whether it’s pursuing a hobby, meditating, going for a hike, or taking yourself out to the movies, spend time with yourself doing the things you enjoy.

Develop trust in yourself by honoring your commitments.

How would you feel if someone consistently broke their word to you or downplayed your needs? Doing this damages relationships—including your relationship with yourself. Whatever commitments you make to show self-love, make sure you honor them and make them a priority.
These five ways to show self-love can help you to develop greater confidence and self-esteem, help you to be happier, and even improve your relationships with others. Remember, there’s only one of you, so treat yourself right.

Listen to what the universe has to say to you, it can reveal a lot about where you need to be and what steps to take towards reaching your goals and happiness.
How many of you feel lost, unhappy and dissatisfied with what you are doing and where you are in the present? How many of you feel — ‘This is not what I am meant to do in life’ or ‘my marriage has no spark’ or ‘my health is suffering’? And are waiting for a miracle to happen.
The truth is whatever is happening in your life is for a reason and there are no coincidences. You might have to endure hardships in life before you find the job you desire, or face financial crisis before you learn how to respect money, or be in an abusive relationship before you realise self-worth, or go through a painful heartbreak before you find your better half and so on. The universe is constantly sending you messages but are you really paying attention or are you just caught up in a rat race?
If you are unhappy, it’s a sign that you aren’t on the right path and need to make changes. You have a choice — the change can either be internal or external. For example, if you are unhappy, you can either make an external change by quitting or internally by changing your perception and how you react to it.

A group of frogs was traveling through the woods and two of them fell into a deep pit. When the other frogs saw how deep the pit was, they told the two frogs that they were as good as dead. The two frogs ignored the comments and tried to jump up out of the pit with all their might. The other frogs kept telling them to stop, that they were as good as dead. Finally, one of the frogs took heed to what the other frogs were saying and gave up. He fell down and died.
The other frog continued to jump as hard as he could. Once again, the crowd of frogs yelled at him to stop the pain and just die. He jumped even harder and finally made it out. When he got out, the other frogs said, “Did you not hear us?” The frog explained to them that he was deaf. He thought they were encouraging him the entire time.

Moral: There is power of life and death in the tongue. An encouraging word to someone who is down can lift them up and help them make it through the day. So be careful of what you say. Speak life to those who cross your path. The power of words… it is sometimes hard to understand that an encouraging word can go such a long way.

What is the brain?

The brain is a complex organ that controls thought, memory, emotion, touch, motor skills, vision, breathing, temperature, hunger and every process that regulates our body. Together, the brain and spinal cord that extends from it make up the central nervous system, or CNS.

What is the brain made of?

Weighing about 3 pounds in the average adult, the brain is about 60% fat. The remaining 40% is a combination of water, protein, carbohydrates and salts. The brain itself is a not a muscle. It contains blood vessels and nerves, including neurons and glial cells.

What is the gray matter and white matter?

Gray and white matter are two different regions of the central nervous system. In the brain, gray matter refers to the darker, outer portion, while white matter describes the lighter, inner section underneath. In the spinal cord, this order is reversed: The white matter is on the outside, and the gray matter sits within.

Gray matter is primarily composed of neuron somas (the round central cell bodies), and white matter is mostly made of axons (the long stems that connects neurons together) wrapped in myelin (a protective coating). The different composition of neuron parts is why the two appear as separate shades on certain scans.Each region serves a different role. Gray matter is primarily responsible for processing and interpreting information, while white matter transmits that information to other parts of the nervous system.

How does the brain work?

The brain sends and receives chemical and electrical signals throughout the body. Different signals control different processes, and your brain interprets each. Some make you feel tired, for example, while others make you feel pain.Some messages are kept within the brain, while others are relayed through the spine and across the body’s vast network of nerves to distant extremities. To do this, the central nervous system relies on billions of neurons (nerve cells).

Main Parts of the Brain and Their Functions:

At a high level, the brain can be divided into the cerebrum, brainstem and cerebellum.

Cerebrum:

The cerebrum (front of brain) comprises gray matter (the cerebral cortex) and white matter at its center. The largest part of the brain, the cerebrum initiates and coordinates movement and regulates temperature. Other areas of the cerebrum enable speech, judgment, thinking and reasoning, problem-solving, emotions and learning. Other functions relate to vision, hearing, touch and other senses.

Cerebral Cortex:

Cortex is Latin for “bark,” and describes the outer gray matter covering of the cerebrum. The cortex has a large surface area due to its folds, and comprises about half of the brain’s weight.The cerebral cortex is divided into two halves, or hemispheres. It is covered with ridges (gyri) and folds (sulci). The two halves join at a large, deep sulcus (the interhemispheric fissure, AKA the medial longitudinal fissure) that runs from the front of the head to the back. The right hemisphere controls the left side of the body, and the left half controls the right side of the body. The two halves communicate with one another through a large, C-shaped structure of white matter and nerve pathways called the corpus callosum. The corpus callosum is in the center of the cerebrum.

Brainstem:

The brainstem (middle of brain) connects the cerebrum with the spinal cord. The brainstem includes the midbrain, the pons and the medulla.

Midbrain. The midbrain (or mesencephalon) is a very complex structure with a range of different neuron clusters (nuclei and colliculi), neural pathways and other structures. These features facilitate various functions, from hearing and movement to calculating responses and environmental changes. The midbrain also contains the substantia nigra, an area affected by Parkinson’s disease that is rich in dopamine neurons and part of the basal ganglia, which enables movement and coordination.

Pons. The pons is the origin for four of the 12 cranial nerves, which enable a range of activities such as tear production, chewing, blinking, focusing vision, balance, hearing and facial expression. Named for the Latin word for “bridge,” the pons is the connection between the midbrain and the medulla.

Medulla. At the bottom of the brainstem, the medulla is where the brain meets the spinal cord. The medulla is essential to survival. Functions of the medulla regulate many bodily activities, including heart rhythm, breathing, blood flow, and oxygen and carbon dioxide levels. The medulla produces reflexive activities such as sneezing, vomiting, coughing and swallowing.

The spinal cord extends from the bottom of the medulla and through a large opening in the bottom of the skull. Supported by the vertebrae, the spinal cord carries messages to and from the brain and the rest of the body.

Cerebellum:

The cerebellum (“little brain”) is a fist-sized portion of the brain located at the back of the head, below the temporal and occipital lobes and above the brainstem. Like the cerebral cortex, it has two hemispheres. The outer portion contains neurons, and the inner area communicates with the cerebral cortex. Its function is to coordinate voluntary muscle movements and to maintain posture, balance and equilibrium. New studies are exploring the cerebellum’s roles in thought, emotions and social behavior, as well as its possible involvement in addiction, autism and schizophrenia.

Brain Coverings:

The outermost layer, the dura mater, is thick and tough. It includes two layers: The periosteal layer of the dura mater lines the inner dome of the skull (cranium) and the meningeal layer is below that. Spaces between the layers allow for the passage of veins and arteries that supply blood flow to the brain.The arachnoid mater is a thin, weblike layer of connective tissue that does not contain nerves or blood vessels. Below the arachnoid mater is the cerebrospinal fluid, or CSF. This fluid cushions the entire central nervous system (brain and spinal cord) and continually circulates around these structures to remove impurities.The pia mater is a thin membrane that hugs the surface of the brain and follows its contours. The pia mater is rich with veins and arteries.

Lobes of the Brain and What They Control:

Frontal lobe. The largest lobe of the brain, located in the front of the head, the frontal lobe is involved in personality characteristics, decision-making and movement. Recognition of smell usually involves parts of the frontal lobe. The frontal lobe contains Broca’s area, which is associated with speech ability.

Parietal lobe. The middle part of the brain, the parietal lobe helps a person identify objects and understand spatial relationships (where one’s body is compared with objects around the person). The parietal lobe is also involved in interpreting pain and touch in the body. The parietal lobe houses Wernicke’s area, which helps the brain understand spoken language.

Occipital lobe. The occipital lobe is the back part of the brain that is involved with vision.Temporal lobe. The sides of the brain, temporal lobes are involved in short-term memory, speech, musical rhythm and some degree of smell recognition.

Deeper Structures Within the Brain:

Pituitary Gland:

Sometimes called the “master gland,” the pituitary gland is a pea-sized structure found deep in the brain behind the bridge of the nose. The pituitary gland governs the function of other glands in the body, regulating the flow of hormones from the thyroid, adrenals, ovaries and testicles. It receives chemical signals from the hypothalamus through its stalk and blood supply.

Hypothalamus: The hypothalamus is located above the pituitary gland and sends it chemical messages that control its function. It regulates body temperature, synchronizes sleep patterns, controls hunger and thirst and also plays a role in some aspects of memory and emotion.

AmygdalaSmall: almond-shaped structures, an amygdala is located under each half (hemisphere) of the brain. Included in the limbic system, the amygdalae regulate emotion and memory and are associated with the brain’s reward system, stress, and the “fight or flight” response when someone perceives a threat.

Hippocampus: A curved seahorse-shaped organ on the underside of each temporal lobe, the hippocampus is part of a larger structure called the hippocampal formation. It supports memory, learning, navigation and perception of space. It receives information from the cerebral cortex and may play a role in Alzheimer’s disease.

Pineal Gland :

The pineal gland is located deep in the brain and attached by a stalk to the top of the third ventricle. The pineal gland responds to light and dark and secretes melatonin, which regulates circadian rhythms and the sleep-wake cycle.

Ventricles and Cerebrospinal Fluid Deep: in the brain are four open areas with passageways between them. They also open into the central spinal canal and the area beneath arachnoid layer of the meninges.The ventricles manufacture cerebrospinal fluid, or CSF, a watery fluid that circulates in and around the ventricles and the spinal cord, and between the meninges. CSF surrounds and cushions the spinal cord and brain, washes out waste and impurities, and delivers nutrients.

Blood Supply to the Brain:

Two sets of blood vessels supply blood and oxygen to the brain: the vertebral arteries and the carotid arteries.The external carotid arteries extend up the sides of your neck, and are where you can feel your pulse when you touch the area with your fingertips. The internal carotid arteries branch into the skull and circulate blood to the front part of the brain.The vertebral arteries follow the spinal column into the skull, where they join together at the brainstem and form the basilar artery, which supplies blood to the rear portions of the brain.The circle of Willis, a loop of blood vessels near the bottom of the brain that connects major arteries, circulates blood from the front of the brain to the back and helps the arterial systems communicate with one another.

Cranial Nerves:

Inside the cranium (the dome of the skull), there are 12 nerves, called cranial nerves:Cranial nerve 1: The first is the olfactory nerve, which allows for your sense of smell.Cranial nerve 2: The optic nerve governs eyesight.Cranial nerve 3: The oculomotor nerve controls pupil response and other motions of the eye, and branches out from the area in the brainstem where the midbrain meets the pons.Cranial nerve 4: The trochlear nerve controls muscles in the eye. It emerges from the back of the midbrain part of the brainstem.Cranial nerve 5: The trigeminal nerve is the largest and most complex of the cranial nerves, with both sensory and motor function. It originates from the pons and conveys sensation from the scalp, teeth, jaw, sinuses, parts of the mouth and face to the brain, allows the function of chewing muscles, and much more.Cranial nerve 6: The abducens nerve innervates some of the muscles in the eye.Cranial nerve 7: The facial nerve supports face movement, taste, glandular and other functions.Cranial nerve 8: The vestibulocochlear nerve facilitates balance and hearing.Cranial nerve 9: The glossopharyngeal nerve allows taste, ear and throat movement, and has many more functions.Cranial nerve 10: The vagus nerve allows sensation around the ear and the digestive system and controls motor activity in the heart, throat and digestive system.Cranial nerve 11: The accessory nerve innervates specific muscles in the head, neck and shoulder.Cranial nerve 12: The hypoglossal nerve supplies motor activity to the tongue.The first two nerves originate in the cerebrum, and the remaining 10 cranial nerves emerge from the brainstem, which has three parts: the midbrain, the pons and the medulla.

Self-discipline delays short-term gratification for long-term reward

Having self-discipline helps us to overcome laziness and procrastination and prevents us from taking things for granted. It directs us to choose what we want now and what we want for the future. Maxwell Maltz, author of a self-help book called “Psycho-Cybernetics: A New Way to Get More Living out of Life”, said, “The ability to discipline yourself to delay gratification in the short term in order to enjoy greater rewards in the long term is the indispensable prerequisite for success”. Self-discipline makes you re-evaluate what you need to do now in order to achieve success in the future. As the saying goes, what you sow now is what you will reap in the future.

solar energy, radiation from the Sun capable of producing heat, causing chemical reactions, or generating electricity. The total amount of solar energy incident on Earth is vastly in excess of the world’s current and anticipated energy requirements. If suitably harnessed, this highly diffused source has the potential to satisfy all future energy needs. In the 21st century solar energy is expected to become increasingly attractive as a renewable energy source because of its inexhaustible supply and its nonpolluting character, in stark contrast to the finite fossil fuels coal, petroleum, and natural gas.

This is essentially because of the enormous radial spreading of radiation from the distant Sun. A relatively minor additional loss is due to Earth’s atmosphere and clouds, which absorb or scatter as much as 54 percent of the incoming sunlight. The sunlight that reaches the ground consists of nearly 50 percent visible light, 45 percent infrared radiation, and smaller amounts of ultraviolet and other forms of electromagnetic radiation.

The potential for solar energy is enormous, since about 200,000 times the world’s total daily electric-generating capacity is received by Earth every day in the form of solar energy. Unfortunately, though solar energy itself is free, the high cost of its collection, conversion, and storage still limits its exploitation in many places. Solar radiation can be converted either into thermal energy (heat) or into electrical energy, though the former is easier to accomplish.

Thermal energy:

Among the most common devices used to capture solar energy and convert it to thermal energy are flat-plate collectors, which are used for solar heating applications. Because the intensity of solar radiation at Earth’s surface is so low, these collectors must be large in area. Even in sunny parts of the world’s temperate regions, for instance, a collector must have a surface area of about 40 square metres (430 square feet) to gather enough energy to serve the energy needs of one person.

The most widely used flat-plate collectors consist of a blackened metal plate, covered with one or two sheets of glass, that is heated by the sunlight falling on it. This heat is then transferred to air or water, called carrier fluids, that flow past the back of the plate. The heat may be used directly, or it may be transferred to another medium for storage. Flat-plate collectors are commonly used for solar water heaters and house heating.The storage of heat for use at night or on cloudy days is commonly accomplished by using insulated tanks to store the water heated during sunny periods. Such a system can supply a home with hot water drawn from the storage tank, or, with the warmed water flowing through tubes in floors and ceilings, it can provide space heating. Flat-plate collectors typically heat carrier fluids to temperatures ranging from 66 to 93 °C (150 to 200 °F).The efficiency of such collectors (i.e., the proportion of the energy received that they convert into usable energy) ranges from 20 to 80 percent, depending on the design of the collector.

Another method of thermal energy conversion is found in solar ponds, which are bodies of salt water designed to collect and store solar energy. The heat extracted from such ponds enables the production of chemicals, food, textiles, and other industrial products and can also be used to warm greenhouses, swimming pools, and livestock buildings. Solar ponds aresometimes used to produce electricity through the use of the organic Rankine cycle engine, a relatively efficient and economical means of solar energy conversion, which is especially useful in remote locations. Solar ponds are fairly expensive to install and maintain and are generally limited to warm rural areas.

On a smaller scale, the Sun’s energy can also be harnessed to cook food in specially designed solar ovens. Solar ovens typically concentrate sunlight from over a wide area to a central point, where a black-surfaced vessel converts the sunlight into heat. The ovens are typically portable and require no other fuel inputs.

Electricity generation:

Solar radiation may be converted directly into electricity by solar cells (photovoltaic cells). In such cells, a small electric voltage is generated when light strikes the junction between a metal and a semiconductor (such as silicon) or the junction between two different semiconductors. (See photovoltaic effect.) The power generated by a single photovoltaic cell is typically only about two watts. By connectinglarge numbers of individual cells together, however, as in solar-panel arrays, hundreds or even thousands of kilowatts of electric power can be generated in a solar electric plant or in a large household array. The energy efficiency of most present-day photovoltaic cells is only about 15 to 20 percent, and, since the intensity of solar radiation is low to begin with, large and costly assemblies of such cells are required to produce even moderate amounts of power.

Small photovoltaic cells that operate on sunlight or artificial light have found major use in low-power applications—as power sources for calculators and watches, for example. Larger units have been used to provide power for water pumps and communications systems in remote areas and for weather and communications satellites. Classic crystalline silicon panels and emerging technologies using thin-film solar cells, including building-integrated photovoltaics, can be installed by homeowners and businesses on their rooftops to replace or augment the conventional electric supply.

Concentrated solar power plants employ concentrating, or focusing, collectors to concentrate sunlight received from a wide area onto a small blackened receiver, thereby considerably increasing the light’s intensity in order to produce high temperatures. The arrays of carefully aligned mirrors or lenses can focus enough sunlight to heat a target to temperatures of 2,000 °C(3,600 °F) or more. This heat can then be used to operate a boiler, which in turn generates steam for a steam turbine electric generator power plant. For producing steam directly, the movable mirrors can be arranged so as to concentrate large amounts of solar radiation upon blackened pipes through which water is circulated and thereby heated.

Solar energy is also used on a small scale for purposes other than those described above. In some countries, for instance, solar energy is used to produce salt from seawater by evaporation. Similarly, solar-powered desalination units transform salt water into drinking water by converting the Sun’s energy to heat, directly or indirectly, to drive the desalination process.

Solar technology has also emerged for the clean and renewable production of hydrogen as an alternative energy source. Mimicking the process of photosynthesis, artificial leaves are silicon-based devices that use solar energy to split water into hydrogen and oxygen, leaving virtually no pollutants. Further work is needed to improve the efficiency and cost-effectiveness of these devices for industrial use.

What is a computer?

A computer is an electronic device that manipulates information, or data. It has the ability to store, retrieve, and process data. You may already know that you can use a computer to type documents, send email, play games, and browse the Web. You can also use it to edit or create spreadsheets, presentations, and even videos.

Hardware vs. software:

Before we talk about different types of computers, let’s talk about two things all computers have in common: hardware and software.

Hardware is any part of your computer that has a physical structure, such as the keyboard or mouse. It also includes all of the computer’s internal parts.

Software is any set of instructions that tells the hardware what to do and how to do it. Examples of software include web browsers, games, and word processors.

Everything you do on your computer will rely on both hardware and software. For example, right now you may be viewing this lesson in a web browser (software) and using your mouse (hardware) to click from page to page. As you learn about different types of computers, ask yourself about the differences in their hardware. As you progress through this tutorial, you’ll see that different types of computers also often use different types of software.

What are the different types of computers?

Desktop computers:

Many people use desktop computers at work, home, and school. Desktop computers are designed to be placed on a desk, and they’re typically made up of a few different parts, including the computer case, monitor, keyboard, and mouse.

Laptop computers:

The second type of computer you may be familiar with is a laptop computer, commonly called a laptop. Laptops are battery-powered computers that are more portable than desktops, allowing you to use them almost anywhere.

Tablet computers:

Tablet computers—or tablets—are handheld computers that are even more portable than laptops. Instead of a keyboard and mouse, tablets use a touch-sensitive screen for typing and navigation. The iPad is an example of a tablet.

Servers:

A server is a computer that serves up information to other computers on a network. For example, whenever you use the Internet, you’re looking at something that’s stored on a server. Many businesses also use local file servers to store and share files internally.

Other types of computers:

Many of today’s electronics are basically specialized computers, though we don’t always think of them that way. Here are a few common examples.

Smartphones: Many cell phones can do a lot of things computers can do, including browsing the Internet and playing games. They are often called smartphones.

Wearables: Wearable technology is a general term for a group of devices—including fitness trackers and smartwatches—that are designed to be worn throughout the day. These devices are often called wearables for short.

Game consoles: A game console is a specialized type of computer that is used for playing video games on your TV.

TVs: Many TVs now include applications—or apps—that let you access various types of online content. For example, you can stream video from the Internet directly onto your TV.

PCs and Macs:

Personal computers come in two main styles: PC and Mac. Both are fully functional, but they have a different look and feel, and many people prefer one or the other.

PCs:

This type of computer began with the original IBM PC that was introduced in 1981. Other companies began creating similar computers, which were called IBM PC Compatible (often shortened to PC). Today, this is the most common type of personal computer, and it typically includes the Microsoft Windows operating system.

Macs:

The Macintosh computer was introduced in 1984, and it was the first widely sold personal computer with a graphical user interface, or GUI (pronounced gooey). All Macs are made by one company (Apple), and they almost always use the Mac OS X operating system.

What you eat and drink each day effects your health and wellbeing, both physically and mentally. Good nutrition, along with regular exercise will help you maintain a healthy weight, while reducing your risk of chronic diseases such as heart disease. However, consuming regular amounts of fast and junk food will impact your quality of health, and will have negative effects on your body.

The Negative Side Of Junk And Fast Food:

Junk foods are food and drinks with low nutritional value (e.g. vitamins, minerals and fibre) and high in kilojoules, fat, sugars and/or salt. On the other hand, fast foods are a type of food you get from a restaurant designed to be delivered to you in the quickest way possible. Some fast foods can be healthy, but typically most fast foods are junk food. For example, salad, sushi and sandwiches are healthy forms of fast food. However, most fast food restaurants, such as McDonalds or KFC serve unhealthy junk food. In Australia, 35% of an average adult’s daily energy intake and 41% of children’s daily energy intake comes from junk food.While the occasional night of junk food won’t hurt much, eating Junk foods regular has been shown to lead to increased risks of obesity and chronic diseases. Cardiovascular disease, type 2 diabetes, non-alcoholic fatty liver disease and some cancers all have causes in excessive junk food consumption. Further, the specific content of many fast foods can have negative side effects for your body;Junk food high in sodium can lead to increased headaches and migraineJunk food high in carbs can trigger outbreaks of acneEating excessive amounts of junk food may increase your risk of depressionThe carbs and sugar in fast foods can lead to dental cavitiesFried foods are filled with trans fats which raise LDL cholesterol levelsFast food is filled with empty carbohydrates, which can lead to increased blood sugar and insulin resistanceIncreased sodium levels can lead to your body retaining excessive water, leading to bloating.

The Key To A Healthy Diet | The Bad Effects Of Eating Junk Food:

To avoid the negative health risks to your, your diet needs to be nutritional and diverse. Small changes to your diet can make an immense difference to your health. It’s easier than you think, especially if you follow at least six of the eight goals outlined below.

Make half your plate fruits and vegetables: The more colourful you plate, the more likely you are to get the vitamins, minerals and fibre your body needs, so be sure to choose a variety of red, orange and green vegetables (such as tomatoes, sweet potatoes and broccoli).

Make half the grains you eat whole grains: eating whole grain foods such as whole-wheat bread will help you avoid processed grains high in empty carbohydrates. Look for whole wheat, brown rice, bulgur, buckwheat, oatmeal, rolled oats, quinoa or wild rice.

Switch to fat-free or low-fat (1%) milk: Fat free and low fat milk contains the same amount of calcium and other nutrients as whole milk, but contains fewer calories and less saturated fat.

Choose a variety of lean protein foods: Lean meats (meat with lower fat content) are far better than meat with large amounts of fat content. Select leaner cuts of beef, turkey breast of chicken breast.

Compare sodium in foods: Use the nutritional facts included in the labels on food packaging to select foods containing low levels of sodium. Choose canned foods with labels stating low sodium, reduced sodium or no salt added.

Drink water instead of sugary drinks: By drinking water or unsweetened, you can cut your calories substantially. Sodas and energy drinks are high in added sugar and calories, so be sure to avoid these. If you seek added flavor, try adding a slice of lemon, lime or watermelon to your glass of water.

Eat some seafood: Seafood such as fish and shellfish are high in protein, minerals and omega-3 fatty acids (healthy fat). Try eating at least eight ounces of seafood a week if you are an adult.

Cut back on solid fats: Major sources of solid fats are cakes, cookies, ice cream and processed meat. Try to avoid these to cut back on your solid fat intake. By following the above eight goals, you will help your body get the nutrients it needs, while cutting back on unhealthy content. If you combine a healthy diet with regular physical exercise, your physical and mental health with begin to improve immensely.

A satellite is a moon, planet or machine that orbits a planet or star. For example, Earth is a satellite because it orbits the sun. Likewise, the moon is a satellite because it orbits Earth. Usually, the word “satellite” refers to a machine that is launched into space and moves around Earth or another body in space.Earth and the moon are examples of natural satellites. Thousands of artificial, or man-made, satellites orbit Earth. Some take pictures of the planet that help meteorologists predict weather and track hurricanes. Some take pictures of other planets, the sun, black holes, dark matter or faraway galaxies. These pictures help scientists better understand the solar system and universe.Still other satellites are used mainly for communications, such as beaming TV signals and phone calls around the world. A group of more than 20 satellites make up the Global Positioning System, or GPS. If you have a GPS receiver, these satellites can help figure out your exact location.

Why Are Satellites Important?

The bird’s-eye view that satellites have allows them to see large areas of Earth at one time. This ability means satellites can collect more data, more quickly, than instruments on the ground.Satellites also can see into space better than telescopes at Earth’s surface. That’s because satellites fly above the clouds, dust and molecules in the atmosphere that can block the view from ground level.Before satellites, TV signals didn’t go very far. TV signals only travel in straight lines. So they would quickly trail off into space instead of following Earth’s curve. Sometimes mountains or tall buildings would block them. Phone calls to faraway places were also a problem. Setting up telephone wires over long distances or underwater is difficult and costs a lot.With satellites, TV signals and phone calls are sent upward to a satellite. Then, almost instantly, the satellite can send them back down to different locations on Earth.

What Are the Parts of a Satellite?

Satellites come in many shapes and sizes. But most have at least two parts in common – an antenna and a power source. The antenna sends and receives information, often to and from Earth. The power source can be a solar panel or battery. Solar panels make power by turning sunlight into electricity.Many NASA satellites carry cameras and scientific sensors. Sometimes these instruments point toward Earth to gather information about its land, air and water. Other times they face toward space to collect data from the solar system and universe.

How Do Satellites Orbit Earth?

Most satellites are launched into space on rockets. A satellite orbits Earth when its speed is balanced by the pull of Earth’s gravity. Without this balance, the satellite would fly in a straight line off into space or fall back to Earth. Satellites orbit Earth at different heights, different speeds and along different paths. The two most common types of orbit are “geostationary” (jee-oh-STAY-shun-air-ee) and “polar.”A geostationary satellite travels from west to east over the equator. It moves in the same direction and at the same rate Earth is spinning. From Earth, a geostationary satellite looks like it is standing still since it is always above the same location.Polar-orbiting satellites travel in a north-south direction from pole to pole. As Earth spins underneath, these satellites can scan the entire globe, one strip at a time.

Why Don’t Satellites Crash Into Each Other?

Actually, they can. NASA and other U.S. and international organizations keep track of satellites in space. Collisions are rare because when a satellite is launched, it is placed into an orbit designed to avoid other satellites. But orbits can change over time. And the chances of a crash increase as more and more satellites are launched into space.In February 2009, two communications satellites – one American and one Russian – collided in space. This, however, is believed to be the first time two man-made satellites have collided accidentally.

What Was the First Satellite in Space?

Sputnik 1 was the first satellite in space. The Soviet Union launched it in 1957.

What Is the History of NASA Satellites?

NASA has launched dozens of satellites into space, starting with the Explorer 1 satellite in 1958. Explorer 1 was America’s first man-made satellite. The main instrument aboard was a sensor that measured high-energy particles in space called cosmic rays.The first satellite picture of Earth came from NASA’s Explorer 6 in 1959. TIROS-1 followed in 1960 with the first TV picture of Earth from space. These pictures did not show much detail. But they did show the potential satellites had to change how people view Earth and space.

How Does NASA Use Satellites Today?

NASA satellites help scientists study Earth and space.Satellites looking toward Earth provide information about clouds, oceans, land and ice. They also measure gases in the atmosphere, such as ozone and carbon dioxide, and the amount of energy that Earth absorbs and emits. And satellites monitor wildfires, volcanoes and their smoke.All this information helps scientists predict weather and climate. The information also helps public health officials track disease and famine; it helps farmers know what crops to plant; and it helps emergency workers respond to natural disasters.Satellites that face toward space have a variety of jobs. Some watch for dangerous rays coming from the sun. Others explore asteroids and comets, the history of stars, and the origin of planets. Some satellites fly near or orbit other planets. These spacecraft may look for evidence of water on Mars or capture close-up pictures of Saturn’s rings.

10 Crazy Facts You Didn’t Know About Space:

There is so much about space, our solar system, and the galaxy that we still don’t know! Space is vast. With billions of galaxies and stars, and planets in our own solar system yet to be fully explored or understood, scientists’ knowledge of space is always evolving. There are, however, some really cool things we know about space right now! We’ve compiled a list of what we think are ten stellar facts that we hope you’ll think are out of this world!

1. SPACE IS COMPLETELY SILENT:

There is no atmosphere in space, which means that sound has no medium or way to travel to be heard.

2. THE HOTTEST PLANET IN OUR SOLAR SYSTEM IS 450° C:

Venus is the hottest planet in the solar system and has an average surface temperature of around 450° C. Did you know that Venus isn’t the closest planet to the sun? That is Mercury. You would think that Mercury would then be the hottest, but Mercury has no atmosphere (which regulates temperature), resulting in big fluctuations.

3. A FULL NASA SPACE SUIT COSTS $12,000,000:

While the entire suit costs a cool $12m, 70% of that cost is for the backpack and control module. However, the space suits that NASA uses were built in 1974. If these were priced by today’s pricing, they would cost an estimated 150 million dollars!

4. THE SUN’S MASS TAKES UP 99.86% OF THE SOLAR SYSTEM:

The Sun accounts for 99.86% of the mass in our solar system with a mass of around 330,000 times that of Earth. Did you know that the Sun is made up of mostly hydrogen (three quarters worth) with the rest of its mass attributed to helium. If the Sun had a voice would it be high and squeaky from all that helium?

5. ONE MILLION EARTHS CAN FIT INSIDE THE SUN:

The Sun is large enough that approximately 1.3 million Earths could fit inside (if squashed in) or if the Earths retained their spherical shape then 960,000 would fit. But can you visualise that number of Earths?

6. THERE ARE MORE TREES ON EARTH THAN STARS IN THE MILKY WAY:

There are about three trillion trees on Planet Earth, and between 100-400 billion stars, approximately, in the galaxy.

7. THE SUNSET ON MARS APPEARS BLUE:

Just as colors are made more dramatic in sunsets on Earth, sunsets on Mars, according to NASA, would appear bluish to human observers watching from the red planet. Fine dust makes the blue near the Sun’s part of the sky much more visibilke, while normal daylight makes the Red Planet’s familiar rusty dust color the most perceptible to the human eye.

8. THERE ARE MORE STARS IN THE UNIVERSE THAN GRAINS OF SANDS ON EARTH:

The universe extends far beyond our own galaxy, The Milky Way, which is why scientists can only estimate how many stars are in space. However, scientists estimate the universe contains approximately 1,000,000,000,000,000,000,000,000 stars, or a septillion. While no one can actually count every single grain of sand on the earth, the estimated total from researchers at the University of Hawaii, is somewhere around seven quintillion, five hundred quadrillion grains. That is an awfully big sand castle!

9. ONE DAY ON VENUS IS LONGER THAN ONE YEAR:

Venus has a slow axis rotation which takes 243 Earth days to complete its day. The orbit of Venus around the Sun is 225 Earth days, making a year on Venus 18 days less than a day on Venus.

10. THERE IS A PLANET MADE OF DIAMONDS:

There’s a planet made of diamonds twice the size of earth The “super earth,” aka 55 Cancri e, is most likely covered in graphite and diamond. Paying a visit to that planet would probably pay for the $12 million dollar space suit needed to get there!

What Are Rainbows?

A rainbow is a multicolored arc in the sky which appears when sunlight hits water droplets. How does it get its colors? Why is it curved? And what is at the end of the rainbow?

Low Sun and Water Droplets

A rainbow can only form under the following conditions:

1. The Sun must be above the horizon and not be obscured by clouds, mountains, or other obstacles.
2.The Sun has to be quite low in the sky. If you are at the same elevation as your horizon, the Sun’s altitude must be below 42° to create a rainbow that can be seen from your perspective. Solar altitude table
3.The air opposite the Sun, as seen from your position, must be filled with a large number of water droplets.

Rainbows always appear in the sky opposite to the Sun. So, if you have your back to the Sun, the rainbow will arch across the sky in front of you.

How Do Rainbows Form?

A rainbow is an optical phenomenon which involves three processes: reflection, dispersion, and refraction.

REFLECTION

Water droplets can act like little mirrors. When a ray of sunlight strikes one of these tiny spheres of water, most of the light bounces off its rear wall and is reflected back. During a rain shower, the air is full of water droplets acting together like a reflective curtain made of millions of minuscule mirrors casting the sunlight back at you.

DISPERSION

But sunlight is white—so, if the water droplets reflect the sunlight, how does the rainbow gets its colors? This is where the second process comes into play: dispersion of light.

Pure sunlight may appear white to us, but it consists of all visible colors. As soon as a ray of sunlight enters a water droplet, it is split up into its components, causing its colors to fan out and become visible as a spectrum of colors. This happens both when the ray enters the droplet and when it leaves the droplet again.

REFRACTION

As the ray of light enters and leaves the water droplet, its direction is also changed slightly in a process called refraction. Each color is refracted in a marginally different direction, creating the impression of a fan of colors. For example, in relation to the direction of the incoming ray of light, the red light component leaves the droplet at a slightly larger angle than the orange component.

The Colors of the Rainbow

This means each water droplet reflects all of the colors of the sunlight back to you. However, because it reflects and refracts each color at a slightly different angle, only one color from each droplet reaches your eyes. For example, you can only see the red light from droplets that are higher in the sky, and only the orange light from the droplets that are a little lower.

This is how the top two stripes of the rainbow—red and orange—form. Further below, the droplets form an even sharper angle between you and the Sun, so they throw the yellow, green, blue, indigo, and violet components of the sunlight back at you, creating the remaining stripes of the rainbow.

Memorize the Color Sequence

If you are having trouble remembering the order of the rainbow colors, simply memorize the name Roy G. Biv. This imaginary first, middle, and last name is an acronym made up of the initial letter of each color, in the order they appear in a rainbow. From top to bottom, they are: red, orange, yellow, green, blue, indigo, and violet.

Why Is a Rainbow Curved?

Technically, a rainbow is the upper half of a circle of light, which centers on the antisolar point, the point directly opposite the Sun, as seen from your perspective. The lower half of the circle, however, is usually not visible since the water droplets hit the ground before it can form. You may be able to see a circular rainbow if you have a high vantage point and the terrain sharply drops off in the direction of the rainbow, allowing the rain to fall down farther and reflect the sunlight from a lower angle. It is also possible to see a circular rainbow from an airplane.

The shape of a rainbow is a result of the refractive index of water. This causes the sunlight to be reflected off rain droplets within a limited range of angles that lie between 0° and 42°. Most of the light is cast back at you in an angular range from 40° for violet light to 42° for red light. This is why the circle of light always has an angular distance of 40-42° from the antisolar point, meaning a rainbow always appears 40-42° away from the point opposite the Sun, as seen from your perspective.

What Is a Double Rainbow?

Sometimes you can see a fainter, second rainbow appear above a rainbow. This happens when sunlight is reflected twice inside each water droplet and directed back to you.

The second rainbow is not as bright as the primary rainbow, because some of the sunlight passes through the droplet, while most of it is reflected. This means more light goes astray when a ray of sunlight is reflected twice, leaving less light to be reflected back to you. The double reflection process also results in an inversion of the colors of the secondary rainbow. Here, the violet stripe is at the top while the red stripe appears at the bottom (click on the image to see this detail).

The angular distance between the second rainbow and the antisolar point is 50-53°, so the two rainbows are always about 10° apart.

Why Is the Area Below the Rainbow Brighter?

While most of the sunlight is concentrated at an angle of 40-42°, some of it is also reflected in the range of 0-39°. Crucially, the angle also determines the extent to which the sunlight is dispersed and refracted. For example, a ray of light that is reflected at 0°—right back where it came from—is not dispersed or refracted at all.

For this reason, we experience it as white light. The same is the case for light that is reflected at higher angles, although to a slightly lesser extent. This is why the area below the main rainbow looks comparatively bright, as shown in the images.

Alexander’s Band

The physical properties of the water droplet prevent the sunlight from being reflected at angles above 42°. For example, it is impossible for a horizontal beam of light to be reflected at an angle of 90° and sent straight down toward the ground. While this maximum reflective angle is a little different for each wavelength (color), ranging from 40° for violet light to 42° for red light, none of the sunlight can be redirected at angles exceeding 42°.

Because of this, water droplets that are more than 42° away from the antisolar point, as seen from your perspective, will not reflect any sunlight back at you. This is why the sky above the primary rainbow looks a great deal darker than the sky below it (see image).

About 10° above the main rainbow, the doubly reflected sunlight of the second rainbow reaches your eyes, so the sky above that is a little brighter again, creating the impression of a dark band of sky sandwiched between the two rainbows. This phenomenon is called Alexander’s band

Is There a Pot of Gold at the End of the Rainbow?

According to an Irish legend, a pot of gold can be found at a rainbow’s end. We probably all agree this is highly unlikely, but did you know it is possible to actually disprove that claim? In fact, you have probably been at the end of the rainbow many times without noticing!

To check the veracity of the pot-of-gold-legend, you need to go to the location where a rainbow touches the ground. This may seem like an impossible feat, given that a rainbow is, in a way, an optical illusion. As tangible and real a bright rainbow may appear, it is formed by countless small reflections of sunlight that are only visible from a certain perspective. This makes it impossible to actually approach a rainbow. If you move toward it, the rainbow will recede at an equal pace; a person who stands at the end of the rainbow you see will see a different, equally unapproachable rainbow farther back, if the weather conditions permit.

But in this realization also lies a chance to empirically disprove the Irish legend. If you can see another person at the end of your rainbow, you can stand at the end of another person’s rainbow, or at least of a rainbow that is visible from a different perspective. So, you have probably been there, at the end of the rainbow, even if that particular rainbow was invisible to you at the time.

India is blessed with a vast and rich heritage. One has only to see the various architectural marvels and cultural institutions that dot the geographical expanse of India to glimpse the richness of our heritage.

The science and technology of ancient India was quite advanced. Many historians believe that most of the scientific advances believed to have been made in Europe had been achieved centuries ago in India. Such advances covered major fields of human knowledge and activities like mathematics, astronomy, physics, medicine, metallurgy, surgery, fine arts, civil engineering and architecture, shipbuilding, navigation, etc.

Indian mathematicians have made important contributions to the study of the decimal number system, zero, negative numbers, arithmetic and algebra. The study of linguistics was initiated by Indian grammarians who began the trend by first attempting to catalogue and codify the rules of Sanskrit. Even today, the main terms for compound analysis are taken from Sanskrit.

India is the birthplace of Ayurveda and Yoga; these systems are now finding many followers in the West. India’s rich spiritual tradition has attracted many troubled Westerners, fleeing the materialistic and spiritually empty worlds they inhabit, to her shores, seeking solace and salvation. India’s urban civilization traces its roots to Mahenjodaro and Harappa, now in Pakistan.

Their planned urban townships were very advanced for their time. Metallurgy is central to most civilizations. The science of smelting was highly refined and precise in ancient India. As early as the 5th century BC, Herodotus, the eminent Greek historian, noted that iron was used in the arrows used by Indian and Persian soldiers.

The idea of the atom is derived from the classification of the material world into five basic elements by Indian philosophers. This classification has been in existence since the Vedic age (c.1500 BC). Indian monuments testify to the different influences in her history – Buddhist, Indo-Saracenic, Victorian, Mughal, etc.

Classical Indian music and dance have a wide fan following all over the world. Each state has its own art forms which are well documented. Imposing and architecturally splendid temples, mosques and churches embody the diverse religious and cultural influences that have made India unique. Cuisine too is an important part of our heritage.

As Indians, we ought to be proud of our rich heritage and strive to preserve it for our descendants by respecting it and ensuring its survival.

Indian Customs and Traditions

The Indian festivals are a reflection of the country’s culture and tradition. There is a set traditional pattern in which these are celebrated. This pattern is being followed since the ancient times. These celebrations offer a great way to meet and greet our loved ones and bring in positive energy. These are a part of our rich heritage.

Indian Art Forms:A part of Its Heritage

Indian Monument.

Indian monuments add to the galore of its heritage. Each of our monuments is known for its marvellous architectural design. Taj Mahal, Qutub Minar, Red Fort, Ajanta and Ellora Caves, Sun Konark temple, Khajuraho Group of Monuments, Buddhist Monuments at Sanchi, Brihadishwara Temple, Hawa Mahal and Mysore Palace are some of the heritage monuments of our country.

Conclusion

Our culture, tradition, monuments, literature and various art forms form a part of our heritage. These have been appreciated worldwide. We are proud to be a part of a country with such a vivacious culture.

Indian Heritage: A Gift from the Older Generations to the Younger Generation

Indian heritage is vast and vivid. It is vast because of the large number of religious groups residing in our country. Each religious group has its own set of customs and traditions which it passes on to its younger generation. However, some of our customs and traditions remain the same throughout India. For instance, our tradition includes respecting our elders, helping the needy, speaking the truth and welcoming guests and treating them nicely. Our traditions teach us to inculcate good habits and make us a good human being.

Our cultural heritage is thus a precious gift from our older generation to help us become a better human being and build a harmonious society.

Value of Indian Heritage for New Generation

Our cultural heritage has remained intact since centuries however its charm seems to be declining in the current times. It seems like the new generation does not seem to value our cultural heritage as much.

Our society has seen tremendous changes in the last few decades. The colonization of our country by the British brought western culture to our country. The age old traditions began to change. Today, Indian attire is highly influenced by the Western culture. Our ancient education system of gurukul was replaced by new kind of schools and many other changes were brought about in that era. Since then, there has been no looking back.

Our society has seen numerous changes. For instance, our joint family system faded away giving way to the new nuclear family system. The growth in technology and the advent of internet and smart phones have further distanced us from our cultural heritage. The western culture allures the youths of the country and most of them look down upon our culture and traditions

The young generation is so engrossed in its own world and has become so self centric that it does not pay much heed to the cultural values given by the elders

Invoking Love and Respect for Indian Heritage

It is the duty of the elders to invoke love for the Indian heritage in the younger generations. This must be done from the very beginning only then we can preserve our rich heritage.

One way of invoking love for our heritage is by acquainting the young generation with our glorious past. This would help in invoking a feeling of pride in them and they would be inspired to continue the tradition and also pass it on to the new generation. This needs a collective effort by the teachers as well as parents.

Schools must teach students about the Indian heritage and how it has survived for centuries. They must also share the importance of preserving it.

Conclusion

Young generation must not only preserve the cultural heritage of India but should also be progressive towards preserving the monumental and natural heritage of our country.

One of the four main families of reptiles, turtles and tortoises have been objects of human fascination for thousands of years. But how much do you really know about these vaguely comical reptiles? Here are 10 facts about turtles and tortoises, ranging from how these vertebrates evolved to why it’s unwise to keep them as pets.

1.Turtle vs Tortoise Linguistics

* Few things in the animal kingdom are more confusing than the difference between turtles and tortoises, for linguistic (rather than anatomical) reasons.

Terrestrial (non-swimming) species should technically be referred to as tortoises, but residents of North America are just as likely to use the word “turtle” across the board.

* Further complicating matters, in Great Britain “turtle” refers exclusively to marine species, and never to land-based tortoises.

* To avoid misunderstandings, most scientists and conservationists refer to turtles, tortoises, and terrapins under the blanket name “chelonians” or “Testudines.” Naturalists and biologists specializing in the study of these reptiles are known as “Testudinologists.”

2.They Are Divided Into Two Major Families

* The vast majority of the 350 or so species of turtles and tortoises are “cryptodires,” meaning these reptiles retract their heads straight back into their shells when threatened.

* The rest are “pleurodires,” or side-necked turtles, which fold their necks to one side when retracting their heads. There are other, more subtle anatomical differences between these two Testudine suborders. For example, the shells of cryptodires are composed of 12 bony plates, while pleurodires have 13, and also have narrower vertebrae in their necks.

* Pleurodire turtles are restricted to the southern hemisphere, including Africa, South America, and Australia. Cryptodires have a worldwide distribution and account for most familiar turtle and tortoise species.

3.The Shells Are Securely Attached to Their Bodies

* You can forget all those cartoons you saw as a kid where a turtle jumps naked out of its shell, then dives back in when threatened.

* The fact is that the shell, or carapace, is securely attached to its body. The inner layer of the shell is connected to the rest of the turtle’s skeleton by various ribs and vertebrae.

* The shells of most turtles and tortoises are composed of “scutes,” or hard layers of keratin. The same protein as in human fingernails.

* The exceptions are soft-shelled turtles and leatherbacks, the carapaces of which are covered with thick skin. Why did turtles and tortoises evolve shells in the first place? Clearly, shells developed as a means of defense against predators.

* Even a starving shark would think twice about breaking its teeth on the carapace of a Galapagos tortoise!

4.They Have Bird-Like Beaks, No Teeth

* You might think turtles and birds are as different as any two animals can be, but in fact, these two vertebrate families share an important common trait: they’re equipped with beaks, and they completely lack teeth.

* The beaks of meat-eating turtles are sharp and ridged. They can do serious damage to the hand of an unwary human, while the beaks of herbivorous turtles and tortoises have serrated edges ideal for cutting fibrous plants.

* Compared to other reptiles, the bites of turtles and tortoises are relatively weak. Still, the alligator snapping turtle can chomp down on its prey with a force of over 300 pounds per square inch, about the same as an adult human male.

* Let’s keep things in perspective, however: the bite force of a saltwater crocodile measures over 4,000 pounds per square inch!

5.Some Live for Over 100 Years

* As a rule, slow-moving reptiles with cold-blooded metabolisms have longer life spans than comparably-sized mammals or birds.

* Even a relatively small box turtle can live for 30 or 40 years, and a Galapagos tortoise can easily hit the 200-year mark.

* If it manages to survive into adulthood (and most turtle babies never get the chance, since they’re gobbled up by predators immediately after hatching), a turtle will be invulnerable to most predators thanks to its shell.

* There are hints that the DNA of these reptiles undergoes more frequent repair and that their stem cells are more easily regenerated.

* It should come as no surprise that turtles and tortoises are avidly studied by gerontologists, who hope to isolate “miracle proteins” that can help extend the human life span.

6.Most Don’t Have Very Good Hearing

* Because their shells provide such a high degree of protection, turtles and tortoises haven’t evolved the advanced auditory capabilities of, for example, herd animals like wildebeest and antelopes.

* Most Testudines, while on land, can only hear sounds above 60 decibels. For perspective, a human whisper registers at 20 decibels.

* This figure is much better in the water, where sound conducts differently. The vision of turtles isn’t much to brag about, either, but it gets the job done, allowing carnivorous Testudines to track prey.

* Also, some turtles are especially well-adapted to seeing at night. Overall, the general intelligence level of Testudines is low, though some species can be taught to navigate simple mazes and others have been shown to possess long-term memories.

7.They Lay Their Eggs in the Sand

* Depending on species, turtles and tortoises lay anywhere from 20 to 200 eggs at a time. One outlier is the eastern box tortoise, which lays only three to eight eggs at once.

* The female digs a hole in a patch of sand and soil deposits her clutch of soft, leathery eggs, and then promptly ambles away.

* What happens next is the kind of thing producers tend to leave out of TV nature documentaries: nearby carnivores raid the turtle nests and devour most of the eggs before they’ve had a chance to hatch.

* For example, crows and raccoons eat about 90 percent of the eggs laid by snapping turtles. Once the eggs have hatched, the odds aren’t much better, as immature turtles unprotected by hard shells are gobbled up like scaly hors-d’oeuvres.

* It only takes one or two hatchlings per clutch to survive in order to propagate the species; the others wind up being part of the food chain.

8.Their Ultimate Ancestor Lived During the Permian Period

* Turtles have a deep evolutionary history that extends to a few million years before the Mesozoic Era, better known as the Age of Dinosaurs.

* The earliest identified Testudine ancestor is a foot-long lizard called Eunotosaurus, which lived in the swamps of Africa 260 million years ago. It had wide, elongated ribs curving along its back, an early version of the shells of later turtles and tortoises.

* Other important links in Testudine evolution include the late Triassic Pappochelys and the early Jurassic Odontochelys, a soft-shelled marine turtle that sported a full set of teeth.

* Over the ensuing tens of millions of years, Earth was home to a series of truly monstrous prehistoric turtles, including Archelon and Protostega, each of which weighed almost two tons.

9.They Don’t Make Ideal Pets

* Turtles and tortoises may seem like the ideal “training pets” for kids (or for adults who don’t have a lot of energy), but there are some very strong arguments against their adoption. First, given their unusually long lifespans, Testudines can be a long-term commitment.

* Second, turtles need very specialized (and sometimes very expensive) care, especially in regard to their cages and food and water supplies.

* Third, turtles are carriers of salmonella, serious cases of which can land you in the hospital and even endanger your life. You don’t necessarily have to handle a turtle to contract salmonella, as these bacteria can thrive on the surfaces of your home.

* The general view of conservation organizations is that turtles and tortoises belong in the wild, not in your kid’s bedroom.

10.The Soviet Union Once Shot Two Tortoises Into Space

* It sounds like a science-fiction TV series, but Zond 5 was actually a spacecraft launched by the Soviet Union in 1968. It was carrying a payload of flies, worms, plants, and two presumably very disoriented tortoises.

* Zond 5 circled the moon once and returned to Earth, where it was discovered that the tortoises had lost 10 percent of their body weight, but were otherwise healthy and active.

* What happened to the tortoises after their triumphant return isn’t known and given the long life spans of their breed, it’s possible that they’re still alive today.

* One likes to imagine them mutated by gamma rays, blown up to monster sizes, and spending their dotage in a post-Soviet research facility on the fringes of Vladivostok.

Record your expenses.

The first step to start saving money is to figure out how much you spend. Keep track of all your expenses—that means every coffee, household item and cash tip.Once you have your data, organize the numbers by categories, such as gas, groceries and mortgage, and total each amount. Use your credit card and bank statements to make sure you’re accurate—and don’t forget any.

The first step to start saving money is to figure out how much you spend.

Once you have an idea of what you spend in a month, you can begin to organize your recorded expenses into a workable budget. Your budget should outline how your expenses measure up to your income—so you can plan your spending and limit overspending. Be sure to factor in expenses that occur regularly but not every month, such as car maintenance.

Budget for savings.

as much as you’d like, it might be time to cut back. Identify non essentials that you can spend less on, such as entertainment and dining out. Look for ways to save on your fixed monthly expenses like television and your cell phone, too.Here are some ideas for trimming everyday expenses:Use resources such as community event listings to find free or low-cost events to reduce entertainment spending.Cancel subscriptions and memberships you don’t use—especially if they renew automatically.

Find ways you can cut your spending.

Commit to eating out only once a month and trying places that fall into the “cheap eats” category.Give yourself a “cooling off period”: When tempted by a nonessential purchase, wait a few days. You may be glad you passed—or ready to save up for it.

Decide on your priorities.

One of the best ways to save money is to set a goal. Start by thinking of what you might want to save for—perhaps you’re getting married, planning a vacation or saving for retirement. Then figure out how much money you’ll need and how long it might take you to save it.

Pick the right tools.

After your expenses and income, your goals are likely to have the biggest impact on how you allocate your savings. Be sure to remember long-term goals—it’s important that planning for retirement doesn’t take a back seat to shorter-term needs.

Instagram (commonly abbreviated to IG, Insta or the gram)[9] is an American photo and video sharing social networking service created by Kevin Systrom and Mike Krieger. In April 2012, Facebook acquired the service for approximately US$1 billion in cash and stock. The app allows users to upload media that can be edited with filters and organized by hashtags and geographical tagging. Posts can be shared publicly or with pre-approved followers. Users can browse other users’ content by tags and locations and view trending content. Users can like photos and follow other users to add their content to a personal feed.

Instagram was originally distinguished by only allowing content to be framed in a square (1:1) aspect ratio with 640 pixels to match the display width of the iPhone at the time. In 2015, these restrictions were eased with an increase to 1080 pixels. The service also added messaging features, the ability to include multiple images or videos in a single post, and a ‘stories’ feature—similar to its main opposition Snapchat—which allows users to post photos and videos to a sequential feed, with each post accessible by others for 24 hours each. As of January 2019, the Stories feature is used by 500 million users daily.

Originally launched for iOS in October 2010, Instagram rapidly gained popularity, with one million registered users in two months, 10 million in a year, and 1 billion as of June 2018.The Android version was released in April 2012, followed by a feature-limited desktop interface in November 2012, a Fire OS app in June 2014, and an app for Windows 10 in October 2016. As of October 2015, over 40 billion photos had been uploaded. Although praised for its influence, Instagram has been the subject of criticism, most notably for policy and interface changes, allegations of censorship, and illegal or improper content uploaded by users.

As of June 2021, the most followed person is Portuguese professional footballer Cristiano Ronaldo with over 300 million followers.The most followed woman is American singer Ariana Grande. As of January 14, 2019, the most-liked photo on Instagram is a picture of an egg, posted by the account @world_record_egg, created with the sole purpose of surpassing the previous record of 18 million likes on a Kylie Jenner post. The picture currently has over 55 million likes.The second most-liked photo is a wedding photo of Ariana Grande and her husband Dalton Gomez.Instagram became the 4th most downloaded mobile app of the 2010s.

RECEPTION

In 2021, Washington Post reported that it has made an international black market for migrant workers, women in Africa and Asia, sold into servitude as maids in Persian Gulf countries.

Awards

Instagram was the runner-up for “Best Mobile App” at the 2010 TechCrunch Crunchies in January 2011. In May 2011, Fast Company listed CEO Kevin Systrom at number 66 in “The 100 Most Creative People in Business in 2011”. In June 2011, Inc. included co-founders Systrom and Krieger in its 2011 “30 Under 30” list.

Instagram won “Best Locally Made App” in the SF Weekly Web Awards in September 2011. 7x7Magazine’s September 2011 issue featured Systrom and Krieger on the cover of their “The Hot 20 2011” issue.In December 2011, Apple Inc. named Instagram the “App of the Year” for 2011.[326] In 2015, Instagram was named No. 1 by Mashable on its list of “The 100 best iPhone apps of all time,” noting Instagram as “one of the most influential social networks in the world.” Instagram was listed among Time’s “50 Best Android Applications for 2013” list

Mental health

In May 2017, a survey conducted by the United Kingdom’s Royal Society for Public Health, featuring 1,479 people aged 14–24, asking them to rate social media platforms depending on anxiety, depression, loneliness, bullying and body image, concluded that Instagram was the “worst for young mental health”. Some have suggested it may contribute to digital dependence, whist this same survey noticed its positive effects, including self-expression, self-identity, and community building. In response to the survey, Instagram stated that “Keeping Instagram a safe and supportive place for young people was a top priority”. The company filters out the reviews and accounts. If some of the accounts violate Instagram’s community guidelines, it will take action, which could include banning them.

In 2017, researchers from Harvard University and University of Vermont demonstrated a machine learning tool that successfully outperformed general practitioners’ diagnostic success rate for depression. The tool used color analysis, metadata components, and face detection of users’ feeds.

Throughout 2019, Instagram began to test the hiding of like counts for posts made by its users.

Correlations have been made between Instagram content and poor body dissatisfaction, as a result of body comparisons. In a recent survey half of the applicants admitted to photo editing behavior which has been linked with concerns over body image.

Negative comments

In response to abusive and negative comments on users’ photos, Instagram has made efforts to give users more control over their posts and accompanying comments field. In July 2016, it announced that users would be able to turn off comments for their posts, as well as control the language used in comments by inputting words they consider offensive, which will ban applicable comments from showing up.[334][335] After the July 2016 announcement, the ability to ban specific words began rolling out early August to celebrities, followed by regular users in September.In December, the company began rolling out the abilities for users to turn off the comments and, for private accounts, remove followers.

In September 2017, the company announced that public users would be able to limit who can comment on their content, such as only their followers or people they follow. At the same time, it updated its automated comment filter to support additional languages.

In June 2017, Instagram announced that it would automatically attempt to filter offensive, harassing, and “spammy” comments by default. The system is built using a Facebook-developed deep learning algorithm known as DeepText (first implemented on the social network to detect spam comments), which utilizes natural-language processing techniques, and can also filter by user-specified keywords.

In July 2019, the service announced that it would introduce a system to proactively detect problematic comments and encourage the user to reconsider their comment, as well as allowing users the ability to “restrict” others’ abilities to communicate with them, citing that younger users felt the existing block system was too much of an escalation.

Culture

On August 9, 2012, English musician Ellie Goulding released a new music video for her song “Anything Could Happen.” The video only contained fan-submitted Instagram photographs that used various filters to represent words or lyrics from the song, and over 1,200 different photographs were submitted.

Security

In August 2017, reports surfaced that a bug in Instagram’s developer tools had allowed “one or more individuals” to gain access to the contact information, specifically email addresses and phone numbers, of several high-profile verified accounts, including its most followed user, Selena Gomez. The company said in a statement that it had “fixed the bug swiftly” and was running an investigation.However, the following month, more details emerged, with a group of hackers selling contact information online, with the affected number of accounts in the “millions” rather than the previously-assumed limitation on verified accounts. Hours after the hack, a searchable database was posted online, charging $10 per search.The Daily Beast was provided with a sample of the affected accounts, and could confirm that, while many of the email addresses could be found with a Google search in public sources, some did not return relevant Google search results and thus were from private sources.The Verge wrote that cybersecurity firm RepKnight had found contact information for multiple actors, musicians, and athletes, and singer Selena Gomez’s account was used by the hackers to post naked photos of her ex-boyfriend Justin Bieber. The company admitted that “we cannot determine which specific accounts may have been impacted”, but believed that “it was a low percentage of Instagram accounts”, though TechCrunch stated in its report that six million accounts were affected by the hack, and that “Instagram services more than 700 million accounts; six million is not a small number”.

In 2019, Apple pulled an app that let users stalk people on Instagram by scraping accounts and collecting data.

Iran has DPI blocking for Instagram.

Content ownership

On December 17, 2012, Instagram announced a change to its Terms of Service policy, adding the following sentence:

To help us deliver interesting paid or sponsored content or promotions, you agree that a business or other entity may pay us to display your username, likeness, photos (along with any associated metadata), and/or actions you take, in connection with paid or sponsored content or promotions, without any compensation to you.

There was no option for users to opt out of the changed Terms of Service without deleting their accounts before the new policy went into effect on January 16, 2013.The move garnered severe criticism from users,prompting Instagram CEO Kevin Systrom to write a blog post one day later, announcing that they would “remove” the offending language from the policy. Citing misinterpretations about its intention to “communicate that we’d like to experiment with innovative advertising that feels appropriate on Instagram”, Systrom also stated that it was “our mistake that this language is confusing” and that “it is not our intention to sell your photos”. Furthermore, he wrote that they would work on “updated language in the terms to make sure this is clear”.

The policy change and its backlash caused competing photo services to use the opportunity to “try to lure users away” by promoting their privacy-friendly services,and some services experienced substantial gains in momentum and user growth following the news.On December 20, Instagram announced that the advertising section of the policy would be reverted to its original October 2010 version.The Verge wrote about that policy as well, however, noting that the original policy gives the company right to “place such advertising and promotions on the Instagram Services or on, about, or in conjunction with your Content”, meaning that “Instagram has always had the right to use your photos in ads, almost any way it wants. We could have had the exact same freakout last week, or a year ago, or the day Instagram launched”

The policy update also introduced an arbitration clause, which remained even after the language pertaining to advertising and user content had been modified.

Environmental pollution is an internationally viewed concern and its effects on ecosystems and human health are very evident. Sources and occurrences of pollutants that are clearly defined and measured in environmental compartments, food and food-related items, and human bodies. Activities urbanization, industrialization, mining, and exploration are at the forefront of global environmental pollution. Both developed and developing nations share this burden together, though awareness and stricter laws in developed countries have contributed to a larger extent in protecting their environment. Despite the global attention towards pollution, the impact is still being felt due to its severe long-term consequences. The decline in environmental quality as a consequence of pollution is evidenced by loss of vegetation, biological diversity, excessive amounts of harmful chemicals in the ambient atmosphere and in food grains, and growing risks of environmental accidents and threats to life support systems. A pollutant can be any chemical or geochemical substance, biological organism or product, or physical substance that is released intentionally or inadvertently by man into the environment with actual or potential adverse, harmful, unpleasant, or inconvenient effects. Pollution can be characterised Air Pollution Water Pollution, Soil/Land Pollution, Noise Pollution, Radioactive Pollution, Thermal Pollution. Which is threatening the environment, humans, plants, animals, and all living organisms.

Environmental pollution caused by the dumping of a wide range of industrial waste is now serious. Hazardous waste sites occur worldwide resulting in the deposition of xenobiotics in soil and water .Like all living creatures, microorganisms need carbon, nutrients, and energy to survive and replicate. Such organisms obtain nutrients and energy from the chemical degradation of contaminants into simple compounds, that is, water, carbon dioxide, salts, and other nontoxic substances. Major sources include the emission of pollutants from power stations, refineries, and petrochemicals, the chemical and fertilizer industries, metallurgical and other industrial plants, and, finally, municipal incineration. Climate is the other side of the same coin that reduces the quality of our Earth. Pollutants such as black carbon, methane, tropospheric ozone, and aerosols affect the amount of incoming sunlight. As a result, the temperature of the Earth is increasing, resulting in the melting of ice, icebergs, and glaciers, ir pollution can have a disastrous effect on allcomponents of the environment, including groundwater, soil, and air. Additionally, it poses a serious threat to living organisms. In this vein, our interest is mainly to focus on these pollutants, as they are related to more extensive and severe problems in human health and environmental impact. Acid rain, global warming, the greenhouse effect, and climate changes have an important ecological impact on air pollution. Ozone is a gas formed from oxygen under high voltage electric discharge It is a strong oxidant, 52% stronger than chlorine. It arises in the stratosphere, but it could also arise following chain reactions of photochemical smog in the troposphere. Ozone can travel to distant areas from its initial source, moving with air masses It is surprising that ozone levels over cities are low in contrast to the increased amounts occuring in urban areas, which could become harmful for cultures, forests, and vegetation as it is reducing carbon assimilation. Ozone reduces growth and yield and affects the plant microflora due to its antimicrobial capacity In this regard, ozone acts upon other natural ecosystems, with microflora and animal species changing their species composition. Ozone increases DNA damage in epidermal keratinocytes and leads to impaired cellular function. Ground-level ozone is generated through a chemical reaction between oxides of nitrogen and VOCs emitted from natural sources and/or following anthropogenic activities. Ozone uptake usually occurs by inhalation. Ozone affects the upper layers of the skin and the tear ducts. A study of short-term exposure of mice to high levels of ozone showed malondialdehyde formation in the upper skin (epidermis) but also depletion in vitamins C and E. It is likely that ozone levels are not interfering with the skin barrier function and integrity to predispose to skin disease. Due to the low water-solubility of ozone, inhaled ozone has the capacity to penetrate deeply into the lungs. Toxic effects induced by ozone are registered in urban areas all over the world, causing biochemical, morphologic, functional, and immunological disorders Daily ozone concentrations compared to the daily number of deaths were reported from different European cities for a 3-year period. During the warm period of the year, an observed increase in ozone concentration was associated with an increase in the daily number of deaths. Environmental pollution is a concern in which all the countries have to come together at the global level and take initiatives.

The history of Egypt has been long and wealthy, due to the flow of the Nile River with its fertile banks and delta, as well as the accomplishments of Egypt’s native inhabitants and outside influence. Much of Egypt’s ancient history was a mystery until Egyptian hieroglyphs were deciphered with the discovery and help of the Rosetta Stone. Among the Seven Wonders of the Ancient World is the Great Pyramid of Giza. There was seen political unification of Upper and Lower Egypt under the first king of the First Dynasty, Narmer. Predominantly native Egyptian rule lasted until the conquest by the Achaemenid Empire in the sixth century BC. In 332 BC, Macedonian ruler Alexander the Great conquered Egypt as he toppled the Achaemenids and established the Hellenistic Ptolemaic Kingdom, whose first ruler was one of Alexander’s former generals, Ptolemy I Soter The Ptolemies had to fight native rebellions and were involved in foreign and civil wars that led to the decline of the kingdom and its final annexation by Rome. The death of Cleopatra ended the nominal independence of Egypt resulting in Egypt’s becoming one of the provinces of the Roman Empire. Egypt remained entirely Ottoman until 1867, except during French occupation from 1798 to 1801. Starting in 1867, Egypt became a nominally autonomous tributary state called the Khedivate of Egypt. However, Khedivate Egypt fell under British control in 1882 following the Anglo Egyptian War. After the end of World War I and following the Egyptian revolution of 1919, the Kingdom of Egypt was established. While a de jure independent state, the United Kingdom retained control over foreign affairs, defense, and other matters. British occupation lasted until 1954, with the Anglo-Egyptian agreement of 1954. The modern Republic of Egypt was founded in 1953, and with the complete withdrawal of British forces from the Suez Canal in 1956, it marked the first time in 2500 years that Egypt was both fully independent and ruled by native Egyptians.

President Gamal Abdel Nasser introduced many reforms and created the short lived United Arab Republic (with Syria). His terms also saw the Six-Day War and the creation of the international Non-Aligned Movement. His successor, Anwar Sadat changed Egypt’s trajectory, departing from many of the political, and economic tenets of Nasserism, re-instituting a multi-party system and launching the Infitah economic policy. He led Egypt in the Yom Kippur War of 1973 to regainEgypt’s Sinai Peninsula, which Israel had occupied since the Six-Day War of 1967. This later led to the Egypt-Israel Peace Treaty. The pharaoh’s role in Egypt was both political and religious pharaohs were generally thought to be imbued with divinity and were effectively regarded as intermediaries between the gods and people, the pharaohs were also responsible for the more earthly concerns of leadership, and each pharaoh had a unique legacy; some were architectural innovators or revered military leaders while others were brilliant diplomats. Djoser is perhaps the most famous Third Dynasty pharaoh he oversaw the construction of the famous step pyramid at Saqqara, a hugely significant milestone in ancient Egyptian architecture. This pyramid, in which Djoser was buried, was the first structure to realise the iconic step design. A Fourth Dynasty pharaoh, Khufu’s greatest legacy is undoubtedly the Great Pyramid of Giza, one of the Seven Wonders of the World. The monumental structure is a testament to the bewildering sophistication of Egyptian architecture and, remarkably, remained the tallest man-made structure in the world for the best part of 4,000 years. Only the second woman to assume the role of pharaoh, Hatshepsut was the wife of Thutmose II and reigned in the Eighteenth Dynasty. Her step-son Thutmose III was just two years old when his father died in 1479 and so Hatshepsut soon took on the role of pharaoh. The son of Amenhotep III, Akhenaten was named Amenhotep IV at birth but changed his name in accordance with his radical monotheistic beliefs. Akhenaten’s wife, Nefertiti, was a strong presence during his reign and played a significant part in his religious revolution After Akhenaten’s death, Egypt rapidly returned to polytheism and the traditional gods he had disowned. The youngest pharaoh in Egyptian history when he ascended to the throne at just nine or 10 years old, Tutankhamun became the most famous pharaoh of all. The cause of his death remains a mystery to Egyptologists. Ramses II’s reign was undoubtedly the greatest of the 19th Dynasty Ramses II went on to declare himself a god, while earning a reputation as a great warrior, fathering 96 children and ruling for 67 years. The last active ruler of the Ptolemaic Kingdom of Egypt, Cleopatra presided over the dying days of the Egyptian empire, yet her fame has lived on through folklore, Shakespeare and Hollywood. It’s hard to disentangle the real Cleopatrafrom the legend but scholars suggest that her portrayal as a stunningly beautiful seductress undersells her brilliance as a leader. Egypt specially grabs attention of people because of its mysteries and Pharos.
