Once a candidate attended an interview for a research post in the Tata Institute. He had passed in the first class. He was asked, "Are there any scientific problems you would like to work on?" There was no satisfactory answer. Physically also the candidate was weak. Raman advised him, "Research is strange work. Success in it brings limit less joy whereas failure pushes one to deep despair. Joy and despair - both require bodily strength. You should first improve your bodily strength through sports and exercises."
In order to encourage scientific research in India, Raman established the Indian Academy of Sciences in 1934. From that year the science journal 'The Proceedings of the Academy' is being published every month.
The Government of Mysore granted 24 acres of land to promote the activities of the Academy. It was his earnest desire 'to bring into existence a centre of scientific research worthy of our ancient country, where the keenest intellectuals of our land can probe into the mysteries of the Universe'. He fulfilled his wish by establishing a Research Institute atHebbal, Bangalore. He did not seek help from the Government but have away all his property to the Institute. The Executive Committee of the Academy named the centre 'Raman Research Institute'.
In 1948 this great scientist entered on one more active phase of life when he became the Director of the Raman Research Institute. The Institute became the centre of all his activities. A garden and tall eucalyptus trees surrounded it. He used to say, "A Hindu is required to go to the forest in old age, but instead of going to the forest, I made the forest come to me." At the Institute he could concentrate on things that interested him. He was alone with his work and was happy. At the entrance to the Institute was a board bearing the words, "The Institute is not open to visitors. Please do not disturb US."
He did research on sound, light, rocks, gems, birds, insects, butterflies, sea shells, trees, flowers, atmosphere,weather and physiology of vision and hearing. His study covered such different fields of science as Physics, Geology, Biology and Physiology. Among them sound and colors particularly attracted him. Once he even went round shops to select sarees of different color designs.
Raman collected rocks and precious stones. His invaluable collection included hundreds of objects such as sand that melted due to lightning, rock indicating the lava flow during a volcano and diamonds, rubies and sapphires. Many fluorescent minerals (that is,minerals having the property of receiving short invisible rays and sending out long visible rays) were kept in a dark room. There he could create a small twinkling world by switching on the ultra-violet light. Thin layers of some crystals were prepared for study. No color was seen when they were viewed perpendicularly. But the viewer had only to change the angle and blue, green and yellow colors delighted the eye. After a deep study of diamonds Raman explained many of their characteristics.
