Science – a boon or bane

Gone is the age of steam. We are now in the age of hydrogen bombs and electricity. The most fantastic dreams of HG Wells in his novel: “The Dream” have come true. In this space age, where the wonders of science excel the wonders of nature, science affects our day-to-day life. Science has surpassed the old cobwebs of mythology and yesterday’s faith has proved to be today’s superstition in the crucible of science.

Yet the problem is whether science is a boon or bane to society. Science nurtures intelligence but leaves the will and emotions uncared for. As Helen Keller has quoted. “Science may have found a cure for most evils, but it has found no
remedy for the worst of them all- the apathy of human beings.”

Science triumphs in automating processes but now it reigns over man. Automation is the order of the day. The specter of war and destruction haunts the world and nobody is safe. Controlling scientific knowledge with moral judgement may be a solution to this dilemma. Audio-visual appliances annihilate times and distances. But more valuable than these concrete achievements is the spirit of science. Science means systematised knowledge. It finds the causes of phenomena, and works through observation and experiments. Science is the torch-bearer of the civilisation.science really a bane? As religion is a Matter of Faith, in the same way science is a Matter of Fact. Modern warfares are destructive beyond the wildest dreams of our unscientific predecessors. Machine guns, shells, submarines, the atom hydrogen bombs and nuclear weapons can destroy the world in the twinkling of an eye. Aeroplanes in war act as engines of mass destruction. Not only in times of war but in times of peace also man lives in the midst of diseases. Thfough cures are being invented, diseases are multiplying too.

It supplements him with acute knowledge and adds to his comforts. It should be refined by the philosophy of love, by a desire to tolerate others and then only man will be able to avert the evil effects that may follow from the misuse of science. An integrated educational pattern, which makes a scientist aware of his social responsibilities, may be a solution to the present turmoil. The extremely genius Albert Einstein once quoted

“To raise new questions, new possibilities, to regard old problems from a new
angle, requires creative imagination and marks real advance in science.”

Indeed, since his times, science has advanced manifolds. More than ever, science has brought hope to the lives of many with its medical advances, genetic engineering, biotechnology, various inventions and discoveries. Science has made it possible for man to live for longer time, decrease the death rate, increase the life expectancy etc.

Moreover, life has become extremely easy only with the help of science. Going places is easy, staying connected with people is convenient and keeping updated with the latest in world, and being entertained are all the blessings of science. Today even a child cannot imagine his life without cartoons. Latest technology toys that can fly, dance, move around, talk etc, mobiles, television, video games, movies and latest clothes are the boon of science.

Biotechnology- An emerging field

Biotechnology, the use of biology to solve problems and make useful products. The most prominent area of biotechnology is the production of therapeutic proteins and other drugs through genetic engineering.

People have been harnessing biological processes to improve their quality of life for some 10,000 years, beginning with the first agricultural communities. Approximately 6,000 years ago, humans began to tap the biological processes of microorganisms in order to make bread, alcoholic beverages, and cheese and to preserve dairy products. But such processes are not what is meant today by biotechnology, a term first widely applied to the molecular and cellular technologies that began to emerge in the 1960s and ’70s. A fledgling “biotech” industry began to coalesce in the mid- to late 1970s, led by Genentech, a pharmaceutical company established in 1976 by Robert A. Swanson and Herbert W. Boyer to commercialize the recombinant DNA technology pioneered by Boyer, Paul Berg, and Stanley N. Cohen. Early companies such as Genentech, Amgen, Biogen, Cetus, and Genex began by manufacturing genetically engineered substances primarily for medical and environmental uses.

In the early years, the main achievement of biotechnology was the ability to produce naturally occurring therapeutic molecules in larger quantities than could be derived from conventional sources such as plasma, animal organs, and human cadavers. Recombinant proteins are also less likely to be contaminated with pathogens or to provoke allergic reactions. Today, biotechnology researchers seek to discover the root molecular causes of disease and to intervene precisely at that level. Sometimes this means producing therapeutic proteins that augment the body’s own supplies or that make up for genetic deficiencies, as in the first generation of biotech medications. (Gene therapy—insertion of genes encoding a needed protein into a patient’s body or cells—is a related approach.)

The biotechnology industry has also expanded its research into the development of traditional pharmaceuticals and monoclonal antibodies that stop the progress of a disease. Successful production of monoclonal antibodies was one of the most important techniques of biotechnology to emerge during the last quarter of the 20th century. The specificity of monoclonal antibodies and their availability in quantity have made it possible to devise sensitive assays for an enormous range of biologically important substances and to distinguish cells from one another by identifying previously unknown marker molecules on their surfaces. Such advances were made possible through the study of genes (genomics), the proteins that they encode (proteomics), and the larger biological pathways in which they act.

Biotechnology has numerous applications, particularly in medicine and agriculture. Examples include the use of biotechnology in merging biological information with computer technology (bioinformatics), exploring the use of microscopic equipment that can enter the human body (nanotechnology), and possibly applying techniques of stem cell research and cloning to replace dead or defective cells and tissues (regenerative medicine). Companies and academic laboratories integrate these disparate technologies in an effort to analyze downward into molecules and also to synthesize upward from molecular biology toward chemical pathways, tissues, and organs.

Albert Einstein

Albert Einstein, (born March 14, 1879, Ulm, Württemberg, Germany—died April 18, 1955, Princeton, New Jersey, U.S.), German-born physicist who developed the special and general theories of relativity and won the Nobel Prize for Physics in 1921 for his explanation of the photoelectric effect. Einstein is generally considered the most influential physicist of the 20th century.

Einstein’s parents were secular, middle-class Jews. His father, Hermann Einstein, was originally a featherbed salesman and later ran an electrochemical factory with moderate success. His mother, the former Pauline Koch, ran the family household. He had one sister, Maria (who went by the name Maja), born two years after Albert.

Einstein would write that two “wonders” deeply affected his early years. The first was his encounter with a compass at age five. He was mystified that invisible forces could deflect the needle. This would lead to a lifelong fascination with invisible forces. The second wonder came at age 12 when he discovered a book of geometry, which he devoured, calling it his “sacred little geometry book.”

Einstein’s education was disrupted by his father’s repeated failures at business. In 1894, after his company failed to get an important contract to electrify the city of Munich, Hermann Einstein moved to Milan to work with a relative. Einstein was left at a boardinghouse in Munich and expected to finish his education. Alone, miserable, and repelled by the looming prospect of military duty when he turned 16, Einstein ran away six months later and landed on the doorstep of his surprised parents. His parents realized the enormous problems that he faced as a school dropout and draft dodger with no employable skills. His prospects did not look promising.

After graduation in 1900, Einstein faced one of the greatest crises in his life. Because he studied advanced subjects on his own, he often cut classes; this earned him the animosity of some professors, especially Heinrich Weber. Unfortunately, Einstein asked Weber for a letter of recommendation. Einstein was subsequently turned down for every academic position that he applied to.

The turning point came later that year, when the father of his lifelong friend Marcel Grossmann was able to recommend him for a position as a clerk in the Swiss patent office in Bern. About then, Einstein’s father became seriously ill and, just before he died, gave his blessing for his son to marry Maric. For years, Einstein would experience enormous sadness remembering that his father had died thinking him a failure.

At first Einstein’s 1905 papers were ignored by the physics community. This began to change after he received the attention of just one physicist, perhaps the most influential physicist of his generation, Max Planck, the founder of the quantum theory.

Soon, owing to Planck’s laudatory comments and to experiments that gradually confirmed his theories, Einstein was invited to lecture at international meetings, such as the Solvay Conferences, and he rose rapidly in the academic world. He was offered a series of positions at increasingly prestigious institutions, including the University of Zürich, the University of Prague, the Swiss Federal Institute of Technology, and finally the University of Berlin, where he served as director of the Kaiser Wilhelm Institute for Physics from 1913 to 1933 (although the opening of the institute was delayed until 1917). Even as his fame spread, Einstein’s marriage was falling apart. He was constantly on the road, speaking at international conferences, and lost in contemplation of relativity. The couple argued frequently about their children and their meager finances. Convinced that his marriage was doomed, Einstein began an affair with a cousin, Elsa Löwenthal, whom he later married. (Elsa was a first cousin on his mother’s side and a second cousin on his father’s side.) When he finally divorced Mileva in 1919, he agreed to give her the money he might receive if he ever won a Nobel Prize.

Einstein also launched the new science of cosmology. His equations predicted that the universe is dynamic—expanding or contracting. This contradicted the prevailing view that the universe was static, so he reluctantly introduced a “cosmological term” to stabilize his model of the universe. In 1929 astronomer Edwin Hubble found that the universe was indeed expanding, thereby confirming Einstein’s earlier work. In 1930, in a visit to the Mount Wilson Observatory near Los Angeles, Einstein met with Hubble and declared the cosmological constant to be his “greatest blunder.” Recent satellite data, however, have shown that the cosmological constant is probably not zero but actually dominates the matter-energy content of the entire universe. Einstein’s “blunder” apparently determines the ultimate fate of the universe.

HOW TO PRODUCE SOLAR ENERGY

Solar energy:

Any energy produced by the sun is referred to as solar energy. Nuclear fusion occurs in the sun and produces solar energy. In the sun’s core, fusion happens when the protons of colliding hydrogen atoms fuse to form helium atoms.

Is solar energy is a Renewable source:

Solar energy is created by the Sun’s light (photovoltaic energy) and warmth (solar thermal energy) and is used to create heat or electricity. Solar energy, which originates from the Sun and is both renewable and inexhaustible, is captured using mirrors and panels.

How is solar energy produce:

Solar panels are used in solar power systems to harness the sun’s energy. To convert solar energy into useful power, these solar panels are typically installed on the roofs of buildings. The electricity gathered in this way is DC current.
DC electricity is transformed into AC (alternating current) electricity using a solar inverter. A grid receives the AC electricity after that. A system known as Solar PV Balance-of-System is used to convert DC electricity to AC.
Certain machinery is used by the BOS System to convert DC to AC. Such equipment consists of:

1.solar panels to generate DC from sunlight.

2. An inverter to convert DC to AC.

3.Solar battery to store the electricity.

4.A few extra electrical wire accessories are required for the system installation to function.

Sources of Solar energy:

Solar energy is created by the Sun’s light photovoltaic energy and its warmth solar thermal energy, and it can be used to produce heat or electricity. Solar energy, which originates from the Sun and is both renewable and inexhaustible, is captured using mirrors and panels.

Types of solar energy:

1.Photovoltaic solar energy.

2. solar thermal energy.

3.Passive solar energy.

4.Hybrid solar energy.

1.Photovoltaic solar energy:

With the aid of a photoelectric effect-based technology, sunlight is transformed into electricity to create photovoltaic solar energy. It is a form of renewable, limitless, and non-polluting energy that may be produced in a variety of settings, from modest home generators to substantial solar power plants.

2.Solar thermal energy:

Solar thermal energy (STE) is the conversion of solar radiation into heat that can be used for a variety of applications, including space and hot water heating, industrial process heating, and power generation.

3.Passive solar energy:

The term “passive solar” refers to the direct utilisation of solar energy for either heating or cooling reasons. Passive solar energy systems do not use mechanical or electronic methods to gather or transform energy, unlike photovoltaic systems or other technological solar power applications.

4.Hybrid solar energy:

A grid-connected, battery-powered renewable energy system known as a hybrid solar system. The system generates electricity during the day using solar panels, and the batteries store any extra energy for use at night when there is no light from the sun.

Advantages of solar power:

1.Solar energy is renewable and inexhaustible source.

2.Every where gets sunlight.

3.It works incredibly well with batteries and the power grid.
