Who is Homi Bhabha

Homi Jehangir Bhabha was an Indian nuclear physicist, founding director, and professor of physics at the Tata Institute of Fundamental Research (TIFR). Born on October 30, 1909, in Bombay, he played a pivotal role in the development of the Indian atomic energy program and is considered one of the most important figures in 20th-century Indian science. Educated in atomic energy at Cambridge University, Bhabha conducted research in the field of electron-positron scattering and later, on cosmic rays. After the independence of India in 1947, Bhabha focused on developing the nuclear research infrastructure of his country. He established the Atomic Energy Commission of India in 1948, serving as its first chairman. Bhabha advocated for the peaceful use of nuclear energy and aimed to make India self-reliant in nuclear research and energy production. Under his leadership, the first atomic research reactor in Asia, named 'Apsara,' was inaugurated in 1956 in Trombay. He also played a key role in formulating India's nuclear policy, emphasizing self-sufficiency in nuclear technology rather than depending on technology transfers from other countries. Tragically, Homi Bhabha's life was cut short when he died in an air crash near Mont Blanc on January 24, 1966. His contributions to Indian science and nuclear energy have left an enduring legacy, significantly shaping the course of scientific research and policy in India.
