Sir Chandrasekhara Venkata RamanC. V. Raman was born at Tiruchirapalli in South India on November 7th, 1888. Raman entered Presidency College, Madras, in 1902, and in 1904 passed his B.A. examination, winning the first place and the gold medal in physics; in 1907 he gained his M.A. degree, obtaining the highest distinction. Raman spent 15 years as a Professor in Physics at Calcutta University (1917-32), and 15 years as a Professor in Physics at the Indian Institute of Science, Bangalore (1933-48). In 1948, Raman became the Director of the Raman Institute of Research at Bangalore, established and endowed by himself. On February 28, 1930, Chandrasekhar Venkata Raman discovered the radiation effect involving the inelastic scattering of light that would bear his name- the Raman effect - and which would win him Asia's first Nobel Prize in any Science subject, in 1930. Raman's research interests were in optics and acoustics - the two fields of investigation to which he dedicated his entire career. The main investigations carried out by Raman were: his experimental and theoretical studies on the diffraction of light by acoustic waves of ultrasonic and hypersonic frequencies (published 1934-1942), and those on the effects produced by X-rays on infrared vibrations in crystals exposed to ordinary light. Raman was elected a Fellow of the Royal Society early in his career (1924), and was knighted in 1929. Besides, Raman was honoured with a large number of honorary doctorates and memberships of scientific societies. C. V. Raman passed away in 1970. |  |  |  |

Prof. S. Chandrasekhar (1910-1995)  Find more ... | | Prof. Subramanyan Chandrasekhar

Born in Lahore, India, in 1910, theoretical astrophysicist Chandrasekhar was elected to the National Acadamy of Sciences (USA) only two years after he became a US citizen in 1953. Chandrasekhar was noted for his work in the field of stellar evolution, and in the early 1930s he was the first to theorize that a collapsing massive star would become an object so dense that not even light could escape it. Although this finding was greeted with some skepticism at the time it was announced, it went on to form the foundation of the theory of black holes, and eventually earned Chandrasekhar a shared Nobel Prize in physics for 1983. Chandrashekhar estimated the limit (Chandrashekhar limit) on the size of a highly dense variety of star known as 'White Dwarf'. If this star's mass exceeds the limit, it explodes to become a bright supernova. He also made significant contributions to understanding the atmosphere of stars and the way matter and motion are distributed among the stars in the galaxy. Chandrashekar, who recieved the Nobel Prize in 1983, was honoured this year when the largest x-ray telescope aboard the US Space Shuttle was named 'Chandra Telescope'. In addition to his work on star degeneration, Chandrasekhar contributed important theorems on the stability of cosmic masses in the presence of gravitation, rotation, and magnetic fields; this work proved to be crucial for the understanding of the spiral structure of galaxies. From the time he came to the US in 1936 until his death in 1995, Chandrasekhar was affiliated with the University of Chicago and its Yerkes Observatory. Chandrasekhar passed away in 1995.|  |  |  |

Prof. S. Bose (1894-1974)  Find more ... | | Prof. Satyendranath Bose Satyendranath Bose was born on the first of January 1894 in Calcutta. He studied at the University of Calcutta, then taught there in 1916, taught at the University of Dacca (1921-45), then returned to Calcutta (1945-56). He did important work in quantum theory, in particular on Planck.html's black body radiation law. Bose sent his work Planck's Law and the Hypothesis of Light Quanta (1924) to Einstein. He wrote a covering letter saying:- Respected Sir, I have ventured to send you the accompanying article for your perusal and opinion. You will see that I have tried to deduce the...
