  • Eminent physicist SN Bose was remembered on his 50th death anniversary.
  • He along with Meghnad Saha, established modern theoretical physics in India.

 

Contributions in the field of Sciences

  • Made significant advances in statistical mechanics and Quantum statistics.
  • Deduced Planck’s Black body radiation law without any reference to classical electrodynamics.
    • Black body radiation refers to the spectrum of radiations emitted by any hot object.
  • Bose’s work titled “Planck’s Law and Light Quantum Hypothesis” was translated into German by Einstein and published in Zeitschrift für Physic.
    • This publication led to emergence of Quantum statistics.
  • Einstein applied Bose’s method to give theory of ideal quantum gas, and predicted phenomenon of Bose-Einstein Condensation (BEC).
    • BEC is a state of matter in which separate atoms or subatomic particles, cooled to near absolute zero (0 Kelvin/ -273.15 0C), coalesce into a single quantum mechanical entity.
    • This single quantum entity can be described by a wave function, on a near-macroscopic scale.

 

Significance of Bose’s contributions

  • Laid the groundwork for contemporary understanding of Standard Model of Physics.
  • Played significant role in fostering scientific collaboration and exchange of ideas between Indian and Western scientists.

Rewards/ Recognitions for SN Bose 

  • Awarded Padma Vibhushan in 1954
  • ‘Bosons’: Fundamental particles with integer spin are named after him.
  • Rabindranath Tagore dedicated his only book on science – ‘Vishwa Parichay’ to SN Bose
  • Became Vice-Chancellor of the Visva-Bharati during 1956-58.
