Boson

Satyendra Nath Bose was born in 1894 in Calcutta (now Kolkata) in Bengal. He studied mathematics and physics at Presidency College and became a professor of physics. In the 1920s, he began working on quantum statistics and Planck's radiation law, trying to derive the formula from first principles using a revolutionary counting method that treated identical particles as truly indistinguishable.

In 1924, Bose sent a paper to Albert Einstein titled 'Planck's Law and the Light Quantum Hypothesis.' Bose had derived Planck's radiation law without treating photons as distinguishable particles—a radical idea. Einstein translated the paper from English to German and submitted it to the Prussian Academy of Sciences. In a note accompanying the submission, Einstein remarked that Bose's method opened a new path in quantum theory. This was effectively Einstein's endorsement.

Bose had discovered that particles with integer spin (like photons) obey different statistical rules than particles with half-integer spin (like electrons). Paul Dirac recognized the significance and coined the term 'boson' for integer-spin particles in Bose's honor. The complementary category, fermions, was named after Enrico Fermi, who had worked on the other class of particles.

Bose continued teaching and research in Calcutta for the rest of his life, relatively obscure in the West. He died in 1974 without having won a Nobel Prize. But in 2012, when CERN announced the discovery of the Higgs boson, Bose's name exploded into global consciousness. Every news article, every physics textbook, now carries his name. He became famous forty years after his death, immortalized in the particle that governs the mass of the universe.
