In 1924, Satyendra Nath Bose proposed a new approach to understand the behaviour of particles or photons, based on quantum theory.
- His collaboration with the Albert Einstein eventually led to postulation of B–E statistics.
About B–E statistics
- It describes ways in which a collection of non-interacting and indistinguishable particles may occupy a set of available discrete energy states at thermodynamic equilibrium.
- In simple words it explains how particles distribute themselves in an available energy states.
- Particles which obey B–E statistics principle are referred as “Bosons”, named after S. N Bose.
- Bosons are fundamental articles that have integer values of spin(0, 1, 2, etc.). E.g. Photon, Gluon, etc.
Relevance/Significance of B–E Statistics
- Enabled first Quantum revolution in 20th century which helped in development of technologies such as lasers, the transistor, Magnetic Resonance Imaging, and semiconductors.
- Second revolution is defined by developments in technologies like quantum computing and quantum sensing, etc.
- Discovery of the fifth state of matter i.e. Bose-Einstein condensate (BEC).
- BEC is a state of matter created when particles are cooled to near absolute zero (-273.15 degrees Celsius/0 Kelvin).
