His observations and theoretical insights were instrumental in solving several mysteries concerning pulsars, interstellar clouds, galaxy topologies, and other celestial bodies.
Sadly, Venkatraman Radhakrishnan passed away at the age of 81 in Bangalore, leaving behind a remarkable legacy of scientific achievements that continue to inspire and contribute to the field of astronomy.
5. S. Chandrashekar
Subrahmanyan Chandrasekhar, an Indian American astrophysicist, was born in Lahore, British India, on October 19, 1910. He gained international recognition when he was awarded the Nobel Prize in Physics in 1983, sharing it with William A. Fowler, for their remarkable contributions to the mathematical theory of black holes. His name is forever associated with the Chandrasekhar limit, a crucial concept in astrophysics.
Chandrasekhar was the nephew of another renowned Indian physicist, CV Raman. In 1953, he became a U.S. citizen, solidifying his connection with the scientific community in the United States.
His work also delved into general relativity, the mathematical theory of black holes, and the theory of colliding gravitational waves, which are the remnants of dying stars.
Subrahmanyan Chandrasekhar passed away on August 21, 1995, in Chicago, at the age of 82, leaving behind a lasting impact on the world of astrophysics and science as a whole.
6. Satyendra Nath Bose
SN Bose, an Indian mathematician and physicist, was a notable figure in the field of quantum mechanics. Born on January 1, 1894, in Calcutta, he made significant contributions that earned him recognition in the scientific community. One of his most significant achievements was in the study of particles, leading to the classification of ‘bosons,’ a term named after him to acknowledge his work, courtesy of Paul Dirac.
Bose’s career took an important turn when he became a Reader at the Physics Department of the University of Dhaka. In 1924, he authored a paper titled “Planck’s Law and the Hypothesis of Light Quanta,” which he sent to Albert Einstein for feedback. Impressed by Bose’s findings, Einstein translated the paper into German and forwarded it to the renowned scientific journal, Zeitschrift für Physik. This recognition opened doors for Bose, allowing him to work at various European X-ray and crystallography laboratories for two years. During this period, he had the opportunity to meet influential scientists like Louis de Broglie, Marie Curie, and Albert Einstein.
