Three Great Scientists

Article excerpt

Sir Chandrasekara Venkata Raman (1888-1970) was awarded the Nobel Prize for Physics in 1930 for his work on the diffusion of light and for the discovery of what is known as the Raman effect. Raman discovered that when a beam oflight passes through a liquid or a gas it is scattered and the frequency of some of the scattered light is changed. This change in frequency provides a way to study the structure of the scattering molecules, and the Raman effect has had wide applications in studying the constitution and properties of various substance--solids, liquids and gases. Born in Trichinopoly, he founded the Indian Journal of Physics and the Indian Academy of Sciences. Srinivasa Ramanujan (1881-1920) was one of the greatest mathematicians of modern times. He was born into a South Indian Brahmin family at Erode, and at the age of 15 his genius was aroused when he verified the results of the 6,000 theorems collected in G.S. Carr's Synopsis of Elementary Results in Pure and Applied Mathematics and then developed his own theorems and ideas. In 1911 he published his first paper in the Journal of the Indian Mathematical Society and in 1914 travelled to England to work with the British mathematician G.H. …
