All members of Technical Research Centre (TRC) along with all of us in the S.N. Bose National Centre for Basic Sciences join in the year of celebration for the 125th birthday of Professor Satyendra Nath Bose.
We bow to the seminal contributions that he made that paved the way for classical modern physics evolve into Quantum Physics of today. His path-breaking way to formulate statistical mechanics for quantum particles with zero or integral spins put the physics of many-particle systems on a firm foundation and this led to the conceptualization of Bose-Einstein Condensation (BEC) in 1920s, a phenomenon that was experimentally confirmed in 2005 in vapours of alkali metals. Particles with spin zero or integral number like the quantum of light photon are called Boson to distinguish them from Fermions, quantum particles with half integral spins like electrons that follow a different statistics.
Modern science of light which we refer to as quantum optics will not exist but for the great discovery of Prof. Bose. The technology of optical communication would also be a non-starter. Though Prof. Bose will always be remembered for his revolutionary theoretical contribution, less known is the fact that Bose was also a pioneer to start experimental crystallography in this part of the world when he was Professor of Physics at the Dacca University (now in Bangladesh). His work in Dacca paved the way to start crystallography of small molecules later in the Calcutta University.
Prof. Bose was a strong believer of propagation of science and scientific temperaments through vernacular and this motivated him to establish organizations that served this cause. He exemplified a person of science moving at ease in the world of literature and music, creating an example of a complete intellectual colossus.
