On this day in 1924, Satyendra Nath Bose sent his quantum formulations to the German scientist Albert Einstein who recognised it as a significant discovery in quantum mechanics.

Brief History of Satyendra Nath Bose

• Satyendra Nath Bose, born January 1, 1894, Calcutta, Indian mathematician and physicist noted for his collaboration with Albert Einstein in developing a theory regarding the gaslike qualities of electromagnetic radiation.
• Bose, a graduate of the University of Calcutta, taught at the University of Dacca (1921–45) and then at Calcutta (1945–56). Bose’s numerous scientific papers (published from 1918 to 1956) contributed to statistical mechanics, the electromagnetic properties of the ionosphere, the theories of X-ray crystallography and thermoluminescence, and unified field theory.
• Bose’s Planck’s Law and the Hypothesis of Light Quanta (1924) led Einstein to seek him out for collaboration.
• Since childhood, his father, who was an accountant, would write an arithmetic problem for him to solve before leaving for work, feulling Bose’s interest in mathematics.

Begining of Bose-Einstein collabration

• Bose had questioned the way particles were counted and began experimenting with his own theories.
• He documented his findings in a report called Planck’s Law and the Hypothesis of Light Quanta, and had sent it to a prominent science journal called The Philosophical Magazine, which later been rejected.
• Then he decided to mail his paper to Albert Einstein and Einstein recognised the significance of the discovery and soon applied Bose’s formula to a wide range of phenomena. Bose’s theoretical paper became one of the most important findings in quantum theory.

The Indian government recognised Bose’s tremendous contribution to physics by awarding him India's second highest civilian award, the Padma Vibhushan.
