India has a history of contributing to the global scientific community, which stretches across centuries from the base of ancient practices to the frontiers of present-day research. The country’s past is filled with great thinkers who turned to worldwide breakthroughs out of a challenge. In fields like quantum mechanics, astrophysics, and space research, our pioneers transformed how we as a world see the universe and the physical world.
- Dr C.V. Raman: The Maestro of Light
Chandrasekhara Venkata Raman, who did what no other scientist from the East had done before, transformed the field of optics. In 1930, he won the Nobel Prize in Physics, the first non-white and Asian to do so, for what proved to be a very radical discovery of the Raman Effect. What he showed is that when light passes through a transparent material, a portion of that light emerges at different wavelengths, which is a result of molecular vibration. While he is known for his work in light scattering, what is also less known is that he was very much into the study of sound, and put out some of the early scientific works on the harmonic structure of Indian percussion instruments like the tabla and the mridangam.
- Homi J. Bhabha: The Architect of Nuclear Physics
Regarded as the architect of India’s nuclear energy program, Homi Jehangir Bhabha made key contributions to quantum theory and cosmic radiation. He put in place the base for national atomic research and served as the first chairman of the Atomic Energy Commission. His theoretical work on electron-positron scattering was of such importance that the phenomenon is known today as Bhabha scattering in the quantum physics community. Bhabha was a strong proponent of the use of nuclear infrastructure to reduce poverty and raise national self-reliance instead of a military focus.
- Sir M. Visvesvaraya: The Engineering Visionary
Sir Mokshagundam Visvesvaraya was a great engineer and architect as well as a statesman who saw through the implementation of what is today’s improved infrastructure in India. He is known for his design of automatic sluice gates and the introduction of large-scale block irrigation networks, which transformed agricultural water management. Also, he developed very efficient filtering systems via collector wells, which brought clean water to large-scale municipal areas. His legacy is recognised every year across the nation on September 15th, which we celebrate as Engineer’s Day.
- Dr A.P.J. Abdul Kalam: The Missile Man and People’s President
Avul Pakir Jainulabdeen Abdul Kalam left his mark for eternity in defence and aerospace engineering. In ISRO, he led India’s early rocketry development, which saw the successful launch of the Rohini satellite into space via the SLV-III program. Later, he took over at the Defence Research and Development Organisation, which he guided to achieve great national ballistic missile capabilities. Known for his devotion to teaching and youth mentorship, which he did very well, Kalam also did distinguished service as India’s 11th President.
- Satyendra Nath Bose: The Subatomic Trailblazer
Satyendra Nath Bose transformed mathematical physics with his work in quantum mechanics. In the 1920s, he put forth a new proof of Planck’s law, which he put forward to Albert Einstein without the use of classical physics. Einstein, who saw the great value in the work, took on the role of a collaborator, which resulted in the development of the basic Bose-Einstein Statistics. To pay homage to his great contribution to quantum theory, physicist Paul Dirac named the set of subatomic force carrier particles bosons after him.
