Abstract

Bhabha's scientific research contributions are descibed in the context of his life and contemporary science. During the Cambridge period(1927-1939),he worked in Positron theory(Bhabha scattering),Cosmic rays (Bhabha- Heitler theory of cosmic ray showers,prediction of heavier electrons) and Meson theory.In Bangalore during 1939-1945, he worked on classical relativistic spinning particles (Bhabha-Corben equations),meson theory and initiated experimental work in cosmic rays in India.He then founded Tata Institute of Fundamental Research in1945 at Bombay and moved there. Here he started work on relativistic wave equations (Bhabha eqns.).He also initiated India's nuclear energy programme in 1948 and this was his main preoccupation later.
