Watershed: The elevated boundary line that separates the headstreams that are tributary to different river basins

The first Indian scientist who received the Nobel Prize was C.V.Raman. His full name was Chandrasekhar Venkata Raman. He was born at Tiruchirapalli in Tamil Nadu on November 7,1888. He had only limited facilities and an equipment worth Rs. 200. Yet he worked hard, thought independently and discovered the Raman Effect which says that light changes its nature when passes through transparent medium. He was the first Indian scholar who studied wholly in India. He was the first Asian and also the first non-white to get the Nobel Prize. He was the pride of India. He passed away in 1970 on November 21.

The man went to Subbiah’s home. There he asked Subbiah’s wife about him. The wife took the man to Subbiah’s godown.

When Raman started his experiment on light, no sophisticate equipment was available in his laboratory. But he was confident he could do the discovery by making some modifications in his experiment. With equipment worth hardly Rs. 200 and limited facilities, Raman made the discovery.

Yes, the man waited for a very long time. He came in the evening and waited till morning. Then he went to Subbiah’s wife who took him to the god own.

Subbiah did not want anyone to know about his secret god own. So, he asked the man to wait. He said that he would have to go and bring rice from some other man.

Water sharing Law: A law regarding water sharing among states

If I were a scientist, I would like to invent a car that could run with the energy of sunlight but not with diesel or petrol.

Yes, even if A.H. Compton had not the ‘Compton Effect’, Raman would have the Raman Effect because Raman was a very optimistic, well-confident and dedicated scientist. He was not a dependent on equipment. He was not confined himself to his laboratory. ,He had independent thinking and was hard-working.

The unseen force working behind Raman for reaching great heights was his confidence, dedication and hard work in what he tried to discover. His confidence was that he could discover with some modifications in his equipment and using the limited facilities made him very great.

Water cycle: Hydrological cycle = The circulation of water from the oceans to the atmosphere, back to the land, and so back to the oceans

Other Indians want good and sophisticated equipment to carry out their experiment. They confine themselves to their laboratories. But C.V. Raman was not dependent on equipment. He had no sophisticated equipment. He did not confine himself to his laboratory. Unlike others, he was hard-working and confident and had independent thinking and looked at the world around him.

Yes, they are special in their attire, appearance and their thoughts. They neither know well of politics nor play them. They spend most of their time in scientific research.

2. C.V. Raman: He was the first Indian to receive the Nobel Prize in Physics for his ‘Raman Effect’. He was also the first Asian and the first non-white to receive the Nobel Prize. He discovered the Raman Effect with equipment worth only Rs. 200/- and limited facilities in his laboratory. He was the first Indian scholar who studied wholly in India. 

3. Srinivasa Ramanujan: He was a great Indian mathematician. He made extraordinary contributions to mathematical analysis, number theory and infinite series. 

4. Albert Einstein: He was a great German physicist. His Theory of Relativity showed that mass and energy are different forms of each other.

5. Isaac Newton: He discovered that sunlight is a mixture of the colours of a rainbow. He built a telescope through which he saw the moons of Jupiter. He discovered the law of gravitational force. 

6. Sir Alexander Fleming: Sir Alexander Fleming was a Scottish biologist, pharmacologist and botanist. His best-known discoveries are the enzyme, lysozyme in 1923 and the antibiotic substance penicillin in 1928, for which he shared the Nobel Prize in Physiology or Medicine in 1999. It was a discovery that changed the course of history. The active ingredient in penicillin turned out to be an infection-fighting agent of enormous potency. When it was finally recognized for what it was, the most efficacious life-saving drug in the world, penicillin would alter forever the treatment of bacterial infections.

Chandrasekhar Venkata Raman was an eminent Indian Scientist. He was the first scholar who studied wholly in India.

He was the first Indian Scientist to receive the Nobel Prize in Physics. He was also the first Asian as well as the first non-white to receive the Nobel Prize.

C. V. Raman was born at Tiruchirapalli in Tamil Nadu on November 7, 1888. His father was a college physics teacher. Right from the start, Raman was a brilliant student. So, when Raman passed his matriculation, his parents wanted to send him abroad for higher studies. But a British surgeon told them not to send him abroad as he was not healthy enough. Raman did his M.A. course at Presidency College in Madras (now called Chennai).

Raman was fond of the Science subject. When he was 19, he became a member of the Indian Association for Cultivation of Science. The headquarters of it was an old building on the busy Bowbazaar Street in Calcutta. Meanwhile Raman took up an administrative job in the Finance Ministry in Calcutta so as to respect the wishes of his parents.

In his youth, Raman was mainly interested in acoustics, the science of sound. He studied how stringed instruments like the sitar and the violin could produce harmonious music. He became a knight of the British Empire in 1929.

With equipment worth only Rs. 200 and limited facilities available in his laboratory, Raman was able to make a discovery known as the Raman Effect, which won him the Nobel Prize in physics in 1930. Earlier, in 1927, Professor A.H. Compton had won the Nobel Prize for the Compton Effect. Compton Effect says that the nature of X-rays changes when passes through the matter. Raman Effect says that the nature of light changes when passes through transparent medium. Raman’s advice to the young scientists was to look at the world around them and not to confine themselves to their laboratories. Raman passed away in 1970 on November 21.

(c) Cosmozoic Theory (Theory of catalysm or catastrophism) 

(d) Catastrophe Theory (Mechanist theory) 

(e) Theory of eternity 

(f) Theory of biogenesis (Mechanist theory) 

(g) Modern theory (The chemical origin of life) 

A hypothesis of spontaneous generation of life on earth: 

According to this theory, the origin of life was from lifeless or non-living substances, from which different types of animals and plants appear suddenly or spontaneously, without any apparent cause. This theory was quiet acceptable in the absence of scientific explanations. This theory was rejected, by the fact that the organism does not appear out of inanimate, lifeless objects.
