Homi Jehangir

Homi Jehangir Bhabha, FRS (30 October 1909 – 24 January 1966) was an Indian nuclear physicist who played a major role in the development of the Indian atomic energy program and is considered to be the father of India's nuclear program. Bhabha was born into a prominent family, through which he was related to Dinshaw Maneckji Petit, Muhammad Ali Jinnah, Homi K Bhabha and Dorab Tata. After receiving his early education at Bombay schools and at the Royal Institute of Science, he attended Caius College ofCambridge University to pursue studies in mechanical engineering. After taking mechanical engineering, he pursued studies underPaul Dirac to complete the Mathematics Tripos. Meanwhile, he worked at the Cavendish Laboratory while working towards his doctorate in theoretical physics under R. H. Fowler. During this time, he embarked on groundbreaking research into the absorption of cosmic rays and electron shower production. Afterward, he published a string of widely-accepted papers on his theories regarding cosmic ray showers.
World War II broke out in September 1939 while Bhabha was vacationing in India. He chose to remain in India until the war ended. In the meantime, he accepted a position at the Indian Institute of Science in Bangalore, headed by Nobel laureate C. V. Raman. He established the Cosmic Ray Research Unit at the institute, and began to work on the theory of the movement of point particles. In 1945, he established the Tata Institute of Fundamental Research in Bombay, and the Atomic Energy Commission of India three
Electron-positron scattering was later named Bhabha scattering, in honor of his contributions in the field.In 1936, Bhabha collaborated with Walter Heitler to formulate a theory on cosmic ray showers. They conjectured that the showers were formed by the cascade production of gamma rays and positive and negative electron pairs. The calculations agreed with the experimental observations of cosmic ray showers made by Bruno Rossi and Pierre Victor
