Key takeaways

India marked the 117th birth anniversary of Dr. Homi Jehangir Bhabha on 30th October 2026.
Bhabha designed India's Three-Stage Nuclear Power Programme to harness domestic Thorium reserves.
He established core institutions including TIFR (1945), AEC (1948), DAE (1954), and AEET (1954), which was later renamed BARC.
His work on relativistic electron-positron scattering is recognized globally as Bhabha Scattering.
He helped create INCOSPAR in 1962 under the Department of Atomic Energy, which later evolved into ISRO.

On 30th October 2026, India observed the 117th birth anniversary of Dr. Homi Jehangir Bhabha.
His vision created India's atomic energy roadmap and built key institutions for space, electronics, and fundamental physics research.

Born in Bombay into a Parsi family, Bhabha initially moved to the UK to study Mechanical Engineering at Cambridge University.
He later shifted his focus to theoretical physics and completed his doctorate in nuclear physics in 1934.

During his years in Europe, Bhabha collaborated with top scientists including Niels Bohr, Paul Dirac, and Wolfgang Pauli while studying quantum mechanics.

He calculated the mathematical probability of scattering positrons by electrons, a process known worldwide as Bhabha Scattering.
In 1937, he developed the Bhabha-Heitler Cascade Theory with Walter Heitler to explain how primary cosmic rays produce subatomic particles in Earth's atmosphere.
His cosmic ray research helped predict the existence of the meson, a subatomic particle later confirmed by experimental physicists.

Bhabha returned to India during World War II and worked with Prime Minister Jawaharlal Nehru to establish indigenous scientific institutions.
He founded the Tata Institute of Fundamental Research (TIFR) in 1945 with help from the Sir Dorabji Tata Trust to train Indian researchers.
He became the first Chairman of the Atomic Energy Commission (AEC) upon its setup in 1948 to guide national nuclear policy.
The government formed the Department of Atomic Energy (DAE) in 1954 directly under the Prime Minister's Office to secure funding and operational independence.
He established the Atomic Energy Establishment, Trombay (AEET) in 1954, which was renamed the Bhabha Atomic Research Centre (BARC) after his death in 1966.

Bhabha designed India's Three-Stage Nuclear Power Programme using PHWRs, Fast Breeder Reactors, and Advanced Heavy Water Reactors.
This plan aimed to use India's massive Thorium reserves in monazite sands rather than relying on imported Uranium.
He led the creation of APSARA, India's first research reactor with 1 MWt capacity, and helped draft the Atomic Energy Act of 1948.

He supported Dr. Vikram Sarabhai in setting up the Indian National Committee for Space Research (INCOSPAR) under the DAE in 1962, which later became ISRO.
He led an electronics committee in the 1960s to foster local manufacturing of electronic parts, helping lay the ground for India's IT sector.
He served as President of the first UN Conference on the Peaceful Uses of Atomic Energy in Geneva in 1955.
He joined the first Scientific Advisory Committee of the International Atomic Energy Agency (IAEA) in 1958 and served on its Board of Governors.
He advocated for peaceful nuclear energy while building a strategic option for defence, which laid the foundation for tests like Pokhran-I (1974) and Pokhran-II (1998).

He was elected a Fellow of the Royal Society in 1941 and received the Padma Bhushan in 1954.
His emphasis on technological self-reliance matches current initiatives like the India AI Impact Summit 2026, which focuses on home-grown technology and global cooperation.
