Satyendra Nath Bose

Source-This post on Satyendra Nath Bose has been created based on the article “Dignitaries trace the evolution of quantum mechanics on 100 years of S N Bose’s colossal work” published on the website of “Department of Science & technology“.

Why in the news?

Distinguished scientists came together to celebrate 100 years of Satyendra Nath Bose’s publications contributing to quantum mechanics.

About Satyendra Nath Bose

Introduction-1) He was an Indian physicist who established modern theoretical physics in India. He is best known for providing the foundation of Bose-Einstein statistics and developing the theory of Bose-Einstein condensates.

2) He was born in Calcutta on January 1, 1894. He was an outstanding student who got inspired from brilliant teachers like Jagadish Chandra Bose and Prafulla Chandra Roy.

3) He started his career in 1916 as a lecturer in physics at Calcutta University and then joined Dacca University.

4) At the University of Dhaka, Bose carried out research and studied the theory of relativity.

Contribution of Satyendra Nath Bose

1) By treating radiation as a gas of photons (Photon gas) and using new statistical techniques for counting photon states, Bose provided a new derivation of Planck’s law.

2) The pioneering ideas of Bose, developed further by Einstein, were confirmed by the observation of a new state of matter in a diluted gas of ultra-cold alkali atoms, the Bose-Einstein condensate. This exotic material exists only when atoms of certain elements are cooled to temperatures near absolute zero.

3) At that point, clusters of atoms begin functioning as a single quantum object with both wave and particle properties.

4) According to scientists, BECs hold crucial information about curious phenomena like dark energy, the unidentified energy thought to be responsible for the universe’s accelerating expansion.
