Satyendranath Bose (S.N. Bose) is an Indian physicist, who specialized in mathematical physics. He was born on 1st January 1894, in Calcutta and was the eldest of the seven siblings. His father Surendranath Bose was an engineer in the East India Railway. He lost his mother at an early age and was brought up by his father. He was very bright from his childhood in his academic career and had keen interest in science.
For pursuing his higher studies, Satyendranath Bose joined Presidency College at Calcutta. The days spent in Presidency College may be called the Golden Age of his academic life, where his future was molded in the company of friends and classmates and the counsel of talented teachers. He studied in the company of renowned scientists like Meghnad Saha, Nikhilranjan Bose, J. C. Ghosh, J. N. Mukherjee and Girijapathi Bhattacharya. He learned under the guidance of such eminent scientists like Jagadishchandra Bose, Prafullachandra Ray, S. N. Maitra. J. C. Bose was his professor of physics while P. C. Ray taught him chemistry in the college. All these great scientists played a vital role in shaping his career.
Satyendranath Bose received a graduation degree at the age of nineteen. He married Usha Devi on the 5th of May 1914 and completed his post graduation next year. He ranked first in all the examinations - the Intermediate, the B.Sc. and the M.Sc. Examinations. The Calcutta University started M.Sc. classes in Modern Mathematics and Modern Physics in the year 1916 and appointed M. N. Saha, J. C. Ghosh and Satyendranath Bose as lecturers.
Satyendranath Bose discharged his duties as a Lecturer in Physics for five years from 1916 to 1921 in Calcutta University. In 1921, he joined Dacca University as a reader in Physics and while serving at the University he wrote a concise article on "Max Planck's Law" and "Light Quantum Hypothesis", which were related to Physics. This article was sent to the renowned scientist Albert Einstein, who was so impressed by it, that he translated it into German and sent it to 'Zeitschrift fur Physik' a famous German periodical for publication. This concise article brought a major change in Satyendranath Bose's life. When his exceptional qualities came to light the Dacca University gave him the money and encouraged him to go to Europe. He went to Paris in 1924 and stayed there for a year. He carried on his research in the highly specialized Madame Curie Laboratory. There he came in contact with several scientists like Schroedinger and Heisenberg. In 1926, Satyendranath Bose returned to Dhaka and was appointed Professor and Head of the Department of Physics in Dacca University and served there for nearly twenty-five years. In 1944, he was the elected as the President of the Indian Science Congress.
Satyendranath Bose conducted research and published an article on theoretical physics on 'Equation of State' jointly with Meghnad Saha. In 1918, this article was published in the 'Philosophical Magazine' and is referred to as 'Saha-Bose Equation'. The Calcutta Mathematical Society published his article entitled 'Stress Equation of Equilibrium' in1919 and another article 'Herpolhode' in 1920. The Philosophical Magazine published his other article on Rydberg's Principle. He contributed in diverse fields like chemistry, mineralogy, engineering, biology, soil science, philosophy, geology, zoology, archaeology, the fine arts, literature and languages.
In 1945, he joined Calcutta University, as Khaira Professor of Physics. He retired in 1956 from Calcutta University. Later he was appointed as the Vice Chancellor of the Viswabharati University. In 1958, he became a Fellow of the Royal Society, London. Satyendranath Bose was a man of exceptional intelligence and was honored for it. In Oxford University he was a legendary figure. He was appointed the President of the National Institute of Sciences. In 1954, the Government of India honored him with the 'Padma Bibhushan' award and in 1964, Delhi University conferred him the degree of Doctor of Science (D.Sc.). He received doctorates from many other universities. He wrote 'Light Quanta Statistics', 'Affine Connection Co-effcients' and many other works of science. Collaborating with Meghnad Saha, Bose translated Einstein's book on the Theory of Relativity from German into English.
This legendary figure passed away on February 04, 1974.
