C V Raman : The Aesthete Physicist

                Chandrasekhara Venkata Raman—the living legend of science of 20th century–breathed science until he breathed his last in 1970. The other distinguished name that comes to my mind while writing about Raman is that of Gurudev Rabindra Nath Tagore whose heart beat for artistic pursuits all his life till his death in 1941. Although Tagore was born in 1861, 26 years earlier than Raman’s birth in 1888, both of them lived into the 20th century when India was struggling against foreign domination and their world-astounding achievements buoyed and rejuvenated imperially suppressed India. The coveted honour, two Nobel Prizes, these representatives of Indian mind brought home infused fresh vitality and vigour into down-hearted Indian people fighting the battle for freedom. The international honour was conferred upon Tagore (Fig 1) in 1913, and then when in 1930 the second honour came, the whole of India watched on Raman (Fig 2) with bated breath, the wonder at Raman’s achievement gave place to belief in prowess of Indian mind and Raman emerged as an internationally known physicist immediately after the discovery of the wonderful phenomena in the study of scattering of light. The honour deservedly bestowed upon Raman brought India in forefront of the commune of nations that prided upon their scientific achievements. The life story of this legend of science reads rather like fiction than real.

On February 28, 1928, at the Indian Association for the Cultivation of Sciences, Kolkata (IACS), C V Raman and his associates showed that when monochromatic light is scattered by transparent media, the scattered light contains not only the original colour, but also other colours. This effect was named as Raman effect. In 1930, for the discovery of the Raman effect and work done on light scattering Raman received the Nobel Prize: the greatest award in the whole world. On the occasion of the 90th anniversary of the Raman effect, a brief  overview about the discovery and its reception by the scientific community is given here.

The first three decades of the 20th century are considered as the “Golden Period” of “Indian Physics”. The well-known facts are: In the beginning of the 1920s; M N Saha gave the Saha ionisation (also known as Saha-Eckert Equation), which explained the structure of stars [1]. On June 4, 1924, S N Bose wrote a letter to Albert Einstein, in which he stated that he (Bose) has derived Planck radiation law by applying his (Einstein’s) quantum nature of light. Einstein translated Bose’s manuscript, which was published in the German journal “Zeitschrift für Physik” [2]. Einstein further developed Bose’s idea. Consequently Bose-Einstein emerged [3]. In 1928 C V Raman, K S Krishnan and S Venkateswaran (Fig 1) discovered the Raman effect.
