Today (December 4, 1898) is the birthday of the Padma Bhushan award-winning Sir Kariamanickam Srinivasa Krishnan, who co-founded the Raman Effect with Sir C.V.Raman.

Today (December 4, 1898) is the birthday of the Padma Bhushan award-winning Sir Kariamanickam Srinivasa Krishnan, who co-founded the Raman Effect with Sir C.V.Raman.

Kariamanickam Srinivasa Krishnan (K.S.Krishnan) was born on December 4, 1898, in Villupanur, a village near Vathirairuppu in Virudhunagar district of Tamil Nadu. His father was a farmer. He had a deep knowledge and knowledge of Tamil and Sanskrit. Krishnan, G. who was at Srivilliputhur. S. Educated at Hindu High School. In 1920, Krishnan was involved in the experimental study of light scattering and its theoretical interpretations in large quantities at the Indian Society for CV Raman Scientific Cultivation in Kolkata. He was instrumental in discovering the Raman scattering. From 1927 to 1929, Krishnan co-authored research papers on the effect of Raman on light diffraction in the journal Nature (about 20 articles).

In 1928 he went to the University of Dhaka as a reader in the field of physics. There he studied the magnetic properties of crystals about their structure. Krishnan, Chandilal Banerjee, P.C. Kuha, and Ashutosh Mukherjee developed an elegant and precise experimental technique for measuring the magnetic anisotropy of magnetic and paramagnetic crystals. Their findings were published in 1933 by the Royal Society of London under the title Inquiries into the Magne-Crystal Activity. In 1933 he returned to Kolkata to hold the post of Sirkar by Professor of Physics Mahendra at the Indian Society of Scientific Cultivation. There he continued to collaborate with Banerjee to explain in detail the magnetic properties of crystals about their structure. Their joint documents and communications were published in the Royal Society of Nature, Spatial Magnetism and Atmospheric Electricity. He wrote numerous articles on magnetic crystals and the basic laws of synthetic physics.

His contribution was to various platforms, such as the Baghdad movement, which was formed for the purpose of peace against nuclear weapons. Apart from the many path contributions they have published in many physics journals, the most definitive scientific studies are on the structure and trends of small crystals to date. Their experiments in Dhaka and continuous joint research in Kolkata led to the so-called Krishnan Banerjee method of measuring the magnetic field of small crystals. Krishnan was elected a Fellow of the Royal Society (FRS) in 1940. His Royal Society candidacy certificate in 1935 states, "He differs for his investigations in molecular optics and Magne-crystal activity. ) Has published Fluorocystis and its major works on crystals.

In 1942, he went to Allahabad University as a professor and head of the Department of Physics. There he took up the physics of solids, especially metals. In 1954 he was awarded the Padma Bhushan by the Government of India. Recipient of the Shanti Swarup Patnagar Memorial Award in 1958 for Valuable Chemical Sciences. On January 4, 1947, Dr K.S. Krishnan was appointed the first director of the National Physics Laboratory India. It was one of the earliest national laboratories set up under the Council for Scientific and Industrial Research. In 1946 he was hailed as a knight. In 1954 he was awarded the Padma Bhushan of India. In 1961, he received the Shanti Swarup Patnagar Memorial Prize for Chemical Sciences.

The stadium of Kalasalingam University was named in his honour and a statue was erected in front of the stadium. A road in the capital Delhi is named after him. He is the Chairman of the Indian National Committee on International Physical Research, Director of the National Physical Research Committee and Scientific Adviser to the Prime Minister of Independent India. I have written Tamil articles on how I got involved in science, what is the age of the earth, solar power, the world revolutionary Einstein, the praises of Krishnan Krishnan. Gratton is not only the greatest scientist but more than that. The Prime Minister of India Nehru has mentioned that he is a good citizen, a good man with integrated virtues.

Nobel laureate Sir C.V. Raman who discovered the Raman effect on scattering of light jointly K.S Krishnan. The famous Indian physicist Kariyamanikkam Siniwasa Krishnan, who co-founded this invention with Raman, passed away on June 14, 1961, at the age of 62.
