Top 10 Greatest Indian Physicists and their Contributions

Top 10 Greatest Indian Physicists and their Contributions are: –

Sir Chandrasekhara Venkata Raman, Nobel Prize Laureate, was an Indian physicist remembered for his pioneering work on scattering of light called the Raman scattering and the result as Raman Effect. He was the first Asian and first non-White to receive any Nobel Prize in the sciences. He worked on the acoustics of musical instruments and was the first to investigate the harmonic nature of the sound of the Indian drums.

Homi Jehangir Bhabha, played an important role in the Quantum Theory. He started his career in nuclear physics from England and returned to India start the nuclear
program in India and becoming the first Chairman of the Atomic Energy Commission of India. He is referred to as father of Indian nuclear power. Electron-positron scattering was named after his huge contribution in the segment as Bhabha scattering. He established the Cosmic Ray Research Unit at Indian Institute of Science, Bangalore under Nobel laureate C. V. Raman and Tata Institute of Fundamental Research in Mumbai. His work was cut short by his mysterious assassination. He encouraged research in electronics, space science, radio astronomy and microbiology.

Sir Mokshagundam Visvesvaraya, a notable Indian engineer, scholar, statesman and the Diwan of Mysore, the Bharat Ratna recipient, strived to make the nation at par with the industrialized nations. He invented ‘automatic sluice gates’ and ‘block irrigation system’ which are still considered to be marvels in engineering. His birth date 15th September each year is celebrated as Engineer’s Day in India.

Venkatraman Radhakrishnan, a globally renowned space scientist, through his extraordinary observations and theoretical insights helped in unraveling many mysteries
surrounding pulsars, interstellar clouds, galaxy structures and various other celestial bodies.

Satyendra Nath Bose, an Indian physicist, specializing in quantum mechanics is most remembered for his role played in the class of particles ‘bosons‘, which were named after him by Paul Dirac to commemorate his work in the field. He adapted a lecture on the theory of radiation and the ultraviolet catastrophe into a short article called “Planck’s Law and the Hypothesis of Light Quanta” which the legendary Albert Einstein appreciated, translated in German and published there in under Bose’s name which ultimately led to the foundation of Bose-Einstein Statistics. He was awarded with the Padma Vibhushan.

Jagdish Chandra Bose, one of the most versatile and multi-talented persons of his era, a polymath, physicist, biologist, botanist and archaeologist, pioneered the study of radio and microwave optics, made important contributions to the study of plants and laid the foundation of experimental science in the Indian sub-continent. He was the first person to demonstrate wireless communication by detecting radio signals through the use of semiconductor. He is also known as father of open technology as he made available freely all his inventions and work so that others may learn and contribute further to the society and humanity as a whole. He did not believe in patenting his work which in itself is a legendary opinion.

Vikram Sarabhai, considered as the Father of India’s space programme, was instrumental in the setting up of the Indian Space Research Organization (ISRO). Besides, he was instrumental in establishing many Indian Institute of repute most notable one being the Indian Institute of Management, Ahmedabad.

S. Chandrashekar, Nobel Prize laureate, is most remembered for his mathematical theory of black holes. He made many notable discoveries like the Chandrasekhar limit which was ultimately named after him. His most notable contributions include the radiation of energy from stars, particularly white dwarf stars, which are the dying fragments of stars.

Meghnad Saha, is most remembered for his work concerning the thermal ionisation of elements which led him to formulate the Saha Equation, the basic tools for

interpretation of the spectra of stars in astrophysics. One can use the equation to determine the ionisation state of the various elements making up the star. He also invented an instrument to measure the weight and pressure of solar rays and he was the chief architect of river planning in India including the Damodar Valley Project.
Avul Pakir Jainulabdeen Abdul Kalam, most famously know as APJ Abdul Kalam worked as an Aerospace engineer with Defense Research and Development Organization and

Indian Space Research Organization. He started his career by designing a small helicopter for the Indian Army. He directed the project India’s first indigenous Satellite Launch Vehicle (SLV-III) which successfully deployed the Rohini satellite in near earth’s orbit. He went ahead to serve as the 11th President of India from 2002 to 2007. Recipient of several prestigious awards, including Bharat Ratna, he still is an inspiration to many budding brains.
