A homage to Sir ChandrasekharaVenkata Raman populary known as C.V.Raman as flashed on the f.b. on Jan.22,2011.

Bishwa Nath Singh:

How many of us remember that great son of our motherland who had honor to be awarded Fellow of Royal Society in 1924,Noble Prize in Physics in 1930,the country’s highest National Civilian Award “Bharat Ratna’’ in 1954,Lenin Peace Prize in 1957 besides many doctorate degrees conferred on him by many universities and every year on the 28th of February, the nation celebrates National Science Day to commemorate the discovery of Raman effec that was discovered by him in 1928! Here, I am to awaken everybody that he was none else than Sir ChandrasekharaVenkata Raman popularly known as C.V.Raman and request all of you to join to pay our respectful homage and floral tribute to him. Let us have a glimpse of his life in brief as appended below!

Sir ChandrasekharaVenkata Raman populary known as C.V.Raman was born at Thiruvanaikaval, near Tiruchirappalli, Madras Presidency to R. Chandrasekhara Iyer (b. 1866) and Parvati Ammal (Saptarshi Parvati).[1] He was the second of their eight ...children. At an early age, Raman moved to the city of Vizag, Andhra Pradesh. Studied in St.Aloysiu there. During his childhood, he had moved to the city of Vizag, Andhra Pradesh. Studied in St.Aloysius Anglo-Indian High Schoo there. His father was a lecturer in Mathematics and physics, so he grew up in an academic atmosphere.His father was a lecturer in mathematics and physics so that from the first he was immersed in an academic atmosphere. He entered Presidency College, Madras, in 1902, and in 1904 passed his B.A. examination, winning the first place and the gold medal, He had done his M.Sc. in physics and topped with distinction in 1907 He had joined the Indian Finance Department He was married on May 6, 1907 to Lokasundari Ammal In 1907 and was posted to Calcutta. Soon after his arrival there, he discovered Sarkar’s Indian Association for the cultivation of science. He began to do his research here before and after office hours until in 1917 Sir Ashutosh appointed him to the Palit Professorship in Physics at the new University College of Science.In 1917 he was offered the newly endowed Palit Chair of Physics at Calcutta University, and decided to accept it. After fifteen years at Calcutta he became Professor at the Indian Institute of Science at Bangalore (1933-1948), and since 1948 he is Director of the Raman Institute of Research at Bangalore, established and endowed by himself. He also founded the Indian Journal of Physics in 1926, of which he is the Editor. Raman sponsored the establishment of the Indian Academy of Sciences and has served as President since its inception. He also initiated the Proceedings of that academy, in which much of his work had been published, and was President of the Indain Science Association, Bangalore that use to publish Current Science (India).Some of Raman’s early memoirs appeared as Bulletins of the Indian Association for the Cultivation of Science (Bull. 6 and 11, dealing with the Maintenance of Vibrations; Bull. 15, 1918, dealing with the theory of the musical instruments of the violin family). He contributed an article on the theory of musical instruments to the 8th Volume of the Handbuch der Physik, 1928. In 1922 he published his work on the Molecular Diffraction of Light, the first of a series of investigations with his collaborators which ultimately led to his discovery, on the 28th of February, 1928, of the radiation effect which bears his name (A new radiation, Indian J. Phys., 2 (1928) 387), and which gained him the 1930 Nobel Prize in Physics.Other 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. In 1948 Raman, through studying the spectroscopic behavior of crystals, approached in a new manner fundamental problems of crystal dynamics. His laboratory has been dealing with the structure and properties of diamond, the structure and optical behavior of numerous iridescent substances Among his other interests has been the optics of colloids, electrical and magnetic anisotropy, and the physiology of human vision. He was honored with a large number of honorary doctorates and memberships of scientific societies. He was elected a Fellow of the Royal Society early in his career (1924), and was knighted in 1929. He was also conferred the highest title of 'Bharat Ratna' in 1954. The 'Raman Effect' was a demonstration of the 'Collision' effect of light bullets (photons) passing through a transparent medium, whether solid, liquid or gaseous. Raman's publications include 'Molecular Diffraction of Light', 'Mechanical Theory of Bowed Strings' and 'Diffraction of X-ray's', Theories of Musical Instruments' etc. Raman conducted pioneering research in musical acoustics, particularly on Tamboura, the well known Indian musical instrument He was also awarded the Lenin Peace Prize in 1957 The grateful nation India celebrates National Science Day on the 28 th of February of every year to commemorate the discovery of the Raman effect in 1928. He had passed away on November 21, 1970 at Bangalore at the age of eighty two leaving millions of his admires to condole his passing away.He was great Scientist besides being a though gentle man with full of passion and wisdom.Let us join to pay our humble obeisance’s to his lotus feet and pay our respectful homage and rich floral tribute to him who will be adored and loved by all for over centuries to come!
