Meghnad Saha FRS (6 October 1893 – 16 February 1956) was an Indian astrophysicist who helped devise the theory of thermal ionisation. His Saha ionisation equation allowed astronomers to accurately relate the spectral classes of stars to their actual temperatures.
Meghnad N. Saha was an Indian astrophysicist noted for his development in 1920 of the thermal ionization equation, which, in the form perfected by the British astrophysicist Edward A. Milne, has remained fundamental in all work on stellar atmospheres.
Oct 5, 2019 · On 6 February 1956, Meghnad Saha, one of India’s greatest scientists, passed away of a heart attack. October 6 is the 126th birth anniversary of Meghnad Saha and even after a century later, his work is still relevant and revered by scientists and researchers across the world.
Meghnad Saha (6 October 1893 – 16 February 1956) was a pioneer in Astrophysics in India. He made a remarkable contribution to the field of Astrophysics. His study of the thermal ionisation of elements led him to formulate what is known as the Saha equation.
Aug 1, 2016 · Meghnad Saha (1893–1956) was an Indian physicist who did much of his work in the last decades of British colonial rule. In the 1920s he made important contributions to the theory of thermal ionization and its application to stellar spectra.
This biography is a short yet comprehensive overview of the life of Meghnad Saha, the mastermind behind the frequently used Saha equations and a strong contributor to the foundation of science in India.
Apr 4, 2017 · A discovery by Indian scientist and statesman Meghnad Saha revealed the nature of stars. by Sam Kean While astronomers had been sorting stars by spectra since the mid-1800s, in 1920 Indian polymath Meghnad Saha was the first to recognize that a star’s spectrum indicated its temperature.
Jul 6, 2023 · Meghnad Saha made significant contributions to the fields of Saha ionization and stellar spectroscopy. His revolutionary work on these subjects, particularly in the area of thermal ionization, has had a lasting impact on our understanding of the universe.
Jul 10, 2024 · Saha was a multi-faceted personality with strong views on political ideology, the role of science in a new nation and other topics. India’s charismatic Prime Minister, Jawaharlal Nehru, during 1947-1964 had a soft corner for sophisticated, suave, upper-crust people. Impatient and angry, confrontational rather than persuasive, Saha did not qualify.
Meghnad Saha (1893–1955) set out his theory in a number of papers published in British journals during 1920–1921. The work was immediately recognized as laying the foundation of quantitative astrophysics. Saha showed that astronomical spectra of.
