New Delhi: Google is celebrating physicist Sir Chandrasekhara Venkata Raman’s 125th birth anniversary with a doodle of his Nobel Prize winning discovery, the Raman Effect, on India homepage.
Born in Thiruvanaikaval (now Tiruchirappalli in Tamil Nadu) on November 7, 1888, Raman studied in St Aloysius Anglo-Indian High School and entered Presidency College in Madras at the age of thirteen in 1902. He graduated in 1904 in first place and won the gold medal in physics and received his M.A. degree with the highest distinctions in 1907.
In 1917, Raman became a professor of physics at the University of Calcutta and conducted research at the Indian Association for the Cultivation of Science (IACS). It was at IACS in 1928 when he discovered the Raman Effect along with fellow researchers including K S Krishnan.
His discovery showed that when light traverses a dust-free, transparent material, some of the scattered light changes in wavelength.
He was conferred a knighthood in 1929 and received the Nobel Prize for Physics in 1930.
In 1932, he discovered the quantum photon spin along with Suri Bhagavantam. He joined the Indian Institute of Science in Bangalore in 1933 and retired in 1944. He established the Raman Research Institute in Bangalore in 1945 and remained active there until his death in 1970, at the age of 82.
