Satyendranath Bose

Satyendranath Bose was born on the first of January 1894 in Calcutta. He studied at the University of Calcutta, then taught there in 1916, taught at the University of Dacca (1921-45), then returned to Calcutta (1945-56).

He did important work in quantum theory, in particular on Planck.html's black body radiation law. Bose sent his work Planck's Law and the Hypothesis of Light Quanta (1924) to Einstein. He wrote a covering letter saying:- Respected Sir, I have ventured to send you the accompanying article for your perusal and opinion. You will see that I have tried to deduce the coefficient .. in Planck's law independent of classical electrodynamics.

It was enthusiastically endorsed by Einstein who saw at once that Bose had removed a major objection against light quanta. The paper was translated into German by Einstein and submitted with a strong recommendation to the Zeitschrift fr Physik.

Bose also published on statistical mechanics leading to the Bose-Einstein statistics. Dirac coined the term boson for particles obeying these statistics. Satyendranath Bose and Albert Einstein published a series of papers on the physics of particles with integer spins (bosons). The duo predicted that if a collection of bosonic atoms could be cooled to the point that each one reaches its lowest possible quantum mechanical energy, a Bose-Einstein condensate would result. In this state, atoms would lose their individual properties and would act collectively as a single entity. Satyendranath Bose passed away in 1974.
