• 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.
