    • 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.
