(PYQ GS paper III Mock Answer: Science & Tech) - Bose Einstein Statistics

Q. Discuss the work of ‘Bose-Einstein Statistics’ done by Prof. Satyendra Nath Bose and show how it revolutionized the field of Physics. (10 Marks)

Answer:

There are two classes of elementary particles - Fermions and Bosons. The Fermions make up matter while the Bosons make up force. The Bose Einstein statistics gives the basic framework to understand the characteristics and the behaviour of the Bosons. The particles bosons are named after Indian Physicist Prof. Satyendra Nath Bose.

There are four fundamental forces in nature, namely Gravitational force, Electromagnetic force, Weak Nuclear force and strong nuclear force. Each of these forces have an associated force particle or Bosons. It is believed that during Big Bang all these forces existed as one but eventually split up into the 4 different forces. The Bose-Einstein Statistics help us understand the interaction of these Bosons (forces) and hence would enhance our understanding of the origin of the universe. 

One of the mysteries physicists have been trying to solve was how particles acquire mass, and this has resulted in theoretical emergence of the concept of Higgs Bosons (God particles). Recently Peter Higgs was awarded Nobel prize for the discovery of Higgs Bosons, the Higgs bosons belong to the class of particles called as Bosons, that obey the Bose Einstein Statistics.

The Bose Einstein Statistics was a pioneering work in the 5th state of matter, namely the Bose-Einstein Condensates. Hence, from the above we can establish that work of ‘Bose-Einstein Statistics’ done by Prof. Satyendra Nath Bose has revolutionized the field of Physics.
