Homi Jehangir Bhabha : Architect of Modern Science and Technology in India

TL;DR

This paper reviews Homi Jehangir Bhabha's pioneering contributions to physics and his foundational role in establishing modern scientific institutions in India, highlighting his research and leadership in nuclear science.

Contribution

It provides a comprehensive overview of Bhabha's scientific achievements and his pivotal role in building India's nuclear and scientific infrastructure.

Findings

Bhabha developed the theory of positron-electron scattering (Bhabha scattering).

He contributed to cosmic ray physics and the prediction of muons.

Bhabha founded key scientific institutions in India, including TIFR and BARC.

Abstract

After describing Bhabha's early life at Bombay, now Mumbai, we discuss his research career at Cambridge, where he made many distinguished contributions to positron physics, cosmic rays and the meson theory. These include theory of positron-electron scattering (Bhabha scattering), Bhabha-Heitler theory of cosmic ray showers and prediction of heavier electrons (ie. muons). Later in his life, after 1945, Bhabha worked in India at Bangalore and Mumbai. In India Bhabha laid foundations of modern nuclear science and technology. He emerged as a successful institution builder founding Tata Institute of Fundamental Research at Mumbai and the Laboratories of Atomic Energy Establishment at Trombay, now renamed as Bhabha Atomic Research Center.
