Dr. Meghnad Saha is a pioneer in the great Indian scientists of physics and astrophysics. This great scientist of slave India also gave his remarkable services in education and social fields. He believed that poverty could be removed by improving the economy of the country.
Meghnad Saha was born on 6 October 1893 in a wealthy family of village Sevratali in Dhaka district of East Bengal. He was the fifth child of father Jagannath Saha and mother Bhuvaneshwari Saha. Along with studying in the primary school of the village, he along with his father used to help him in the shop. For further studies, he had to go to school located at a distance of 11 km. While studying in the school in 1905, he also suffered punishment for school expulsion while protesting during the break-up.
In 1909, he passed the matriculation examination and secured the first position in the entire province. Passed Intermediate Examination of Science in 1911. Educated with scientists like Jagdish Chandra Basu, Prafulla Chandra Roy from Presidency College, Calcutta. Passed Bsc exam in 1913 and Msc in 1915. He wanted to appear in the competitive examination of Indian Finance, but he was denied due to the extreme political ideology. Now he decided to do research in the field of mathematics and physics.
In 1916, he was appointed Professor of Mathematics in the University of Science College. During the First World War, when physics professor Devendramohan Basu was under house arrest in Germany, he also took charge of physics. While teaching heat and thermodynamics, he did a deep work on heat and also wrote important books. His research essays were also published in reputed journals called Philosophical Magazine of England and Physical Review of America.
In the new theory, which was proposed by Dr. Meghnad Saha, it proved that atoms of the Sun’s chromosome are ionized at higher temperatures and at lower pressures. For this reason, some lines appear thick in the Rashmikritas of the Sun’s spectrum. This principle of Dr. Saha proved very helpful in measuring its distance from the Rashmikritas of Taro. In September 1919, Dr. Saha (Meghnad Saha) went to Europe for the purpose of completing research. He did his research in Prof. Fowler’s laboratory and then in Cambridge’s Vendesh Laboratory. Then he went to Germany and worked in Prof. Nirst’s laboratory.
All the scientists practiced their physical principles. The experiments which Germany had started, faced difficulties in the absence of a full fledged laboratory upon coming to India. While giving scientific lectures in the country and abroad, he got his talent ironed. In 1927, he was elected a Fellow in the Royal Society of London for work related to space ray theory. After that he represented India at the International Physical Science Conference held in Italy. From there he went to Norway to investigate the complete solar eclipse with scientists.
Along with the Astronomy of England, he was also elected a Fellow of the Royal Asiatic Society of Bengal. In the Bombay session, he gave the theories about the origin of the universe and creation and numerous constellations. With his efforts, the National Institute of Science of Calcutta was established on 7 January 1935. In 1935, he was awarded a fellowship by the Carnegie Trust of America for his work on upward atmosphere. He proved that the pressure of light does not affect all things. This pressure is more or less on the molecules of matter.
Due to the temperature of the sun, some colors are bright and sharp in the sunlight. If atoms of an element start to exploit around them, atoms are generated by energy absorption. This discovery of optics and thermodynamics made important discoveries related to radiation pressure, metals, and the color of salts. Dr. Saha was the chairman of the Molecular Research Committee from 1945-47 and the Chairman of the Atomic Power Research Commission in 1948. The credit for the formation of the University Grants Commission and the creation of the National Panchag goes to him.
Dr. Saha (Meghnad Saha) will always be remembered for his scientific research and social, economic and educational reforms all over India. This great science seeker died on 15 February 1956.
