Google honours Indian astrophysicist S. Chandrasekhar with doodle
Google honoured astrophysicist Subrahmanyan Chandrasekhar with a doodle on his 107th birth anniversary. He is the first astrophysicist to win a Nobel Prize for his theory on the evolution of stars. He jointly won the award with Dr William Fowler of the California Institute of Technology in 1983.
The Indian-American astrophysicist, known for his theory of white dwarfs, was born on October 19, 1910, to a Tamil family in Lahore (now in Pakistan). Chandrasekhar studied in the Presidency College, Madras, and later in Cambridge University before moving to the US in 1936.
While working as a researcher at the University of Cambridge, he developed a theory which came to be known as the “Chandrasekhar Limit”, which said the mass of a white dwarf could not exceed 1.44 times that of the sun and his calculations threw new light on Supernovas, Neutron stars and Black Holes.
Penning his first scientific paper at the age of 20, on the theory of evolution of stars, he joined the University of Chicago as a Deputy Professor at the age of 26, and worked there throughout his career till retirement in 1980.Chandrasekhar was the nephew of Indian scientist 1920 Nobel laureate, Sir Chandrasekhar Venkat Raman, celebrated Indian scientist who is renowned for his work in the area of scattering of light called “Raman Effect”. Chandrasekhar also contributed to the study of the theory of colliding gravitational waves. Later NASA honoured him by naming its top X-ray observatory as the “Chandra X-ray Observatory”.
He migrated to the US in 1937. In 1944, he was elected to the Royal Society of London, at age 34. After marriage with LalithaDoraiswamy in 1936, the couple became US citizens. Continuing as a researcher after superannuation, in 1983 Chandrasekhar wrote his renowned mathematical theory on Black Holes which were first discovered in 1972. After an illustrious scientific career, Chandrasekhar passed away in Chicago following a heart attack on August 21, 1995. His wife expired in 2013 at the age of 102.
