At the age of 21, Satyendra earned a master’s degree from the University of Calcutta and he did so by securing 92% marks a record which stands unbroken up to this date. This was 1915, when Einstein published the theory of relativity. Little did he know that a young man in India had translated his work.
When he was giving a lecture in Dhaka Uni he felt dissatisfied with the existing derivations of Plank's radiation law. After that he wrote a paper deriving the same result without the use of classical physics.
Even though Bose had made a breakthrough, his method was rejected by all those around. Despite this, he sent the paper directly to Albert Einstein in a letter writing:
--------------------------------------
Respected Sir,
I am anxious to know what you think of it. Though a complete stranger to you, I do not feel any hesitation in making such a request because we are all your pupils, thoroughly profiting only by your teachings and through your writings.

Einstein was hooked. He translated the paper into German and had it published published it in Zeitschrift fur Physik under Bose’s name. He wrote back to Bose saying:
"..your paper is a beautiful step forward…"
Einstein adopted Bose’s idea and extended it to atoms and this lead him to predict which now we call Bose-Einstein condensate (BEC). What Bose showed in his paper was that in the case of photons, classical statistics does not hold much relevance – it’s a new statistics which is now called Bose statistics.
Particles following Bose statistics came to be known as bosons, named by Paul Dirac.
Despite his pioneering contribution, Bose was not awarded a Nobel Prize. Bose passed away in 1974.
He is regarded as a forgotten hero but a man of his calibre can never be forgotten as his name is associated with one half the particles in this world.
Since there are two kinds of particles in the universe – Bosons and Fermions so half the particles in this universe are Bosons.
