Meghnad Saha
Since childhood, Meghnad used to look at the sun, moon, stars etc. in the sky.
India’s famous astronomer and nuclear physics expert Shri Meghnad Saha was born on 6 October 1893 in Seoratali village of Dhaka district. Father Jagannath Saha and mother Bhuvaneshwari Devi were from an economically backward family.
Seeing his inquisitive nature and intelligence, Meghnad’s teachers met his family and inspired him to study further.
Dr. Anant Kumar Das helped Meghnad to study further. Meghnad stood highest in the entire Dhaka district in eighth grade and received a scholarship.
In those days, demonstrations started against the partition policy of the British government.
Due to his participation in the freedom struggle, his scholarship was stopped and he was also expelled from school. On the basis of his merit, he got admission in a private school.
Later he also participated in revolutionary activities along with Subhash Chandra Bose.
But these later affected his career also.
Got selected in IFC. But he did not get the job, because he had played an active role in the freedom movement.
Meghnad Saha chose study-teaching as his field of work.
Meghnad joined Hindu College, Calcutta, now called Presidency College, to pursue his graduation.
Here Satyendra Bose was his classmate. Meghnad was very interested in science and mathematics.
Teachers like Professor Jagadish Chandra Basu and Prafulla Chandra Ray kept motivating these people for in-depth study.
Dr
Meghnad Saha made a new discovery as a solution to the problem in astrophysics. Which the world knows as “Ionization Formula”. This is a description of the chemical and physical conditions of the stars, which astronomers called a major discovery in astronomy.
Dr. Saha also discovered radio waves from the Sun and radio activity.
Meghnad Saha’s discovery “Ionization Formula” was described by a famous astronomer as the 12th major discovery of astronomy. This formula is able to give astronomers information about the “internal temperature and pressure” of the Sun, Moon and other stars.
This discovery is considered one of the 10 major discoveries of science and is very useful even today.
Radio waves from the Sun and radio activity were also discovered by Dr. Saha.)
Dr. Meghnad Saha also created India’s first device called Cyclotron.
In 1920, Saha went to England and came in contact with many scientists.
Was elected Fellow of the Royal Society at a very young age.
After meeting various scientists abroad, Meghnad had understood that nuclear physics was going to be used extensively in the future. To ensure that India does not lag behind in this field, he made intensive efforts and Nuclear Physics started being taught in Kolkata University.
Einstein’s Theory of Relativity was also translated by Dr. Meghnad Saha.
Einstein described Dr. Meghnad Saha’s theory of “behavior of elements at high temperatures” as a special contribution to the world.
At that time, information about research in the field of science used to reach India very late.
Dr. Saha was also associated with the Indian Science News Association.
With the aim of making science accessible to the common people in easy language, he also brought out a monthly magazine on the subject of science and culture.
He also wrote many books himself.
“Dr. Saha played an important role in establishing many institutions. Like
*Indian Institute of Nuclear Physics
*National Academy of Science India (Prayag)
*Indian Society of Physics
* International Astronomical Union etc.
Apart from physics, Meghnad Saha also studied ancient Indian history, biology and archeology in depth.
He had seen the horrors of flood in his childhood, hence he studied deeply about the causes and prevention of floods. Was involved in many river dam projects and power projects including Damodar Valley Project.
Meghnad Saha, along with being a scientist, was a social worker, practical and popular personality.
He contributed towards the rehabilitation of displaced people during the partition of Bengal.
In 1952, as an independent candidate, he won from Kolkata with a huge majority and became the MP of the first Lok Sabha and made active contribution in the National Planning Commission along with Nehruji.
In 1952, Prime Minister Nehru appointed him the chairman of the committee to prepare the Indian National Calendar. Under the leadership of Dr. Saha, India’s National Solar Day Guide was created, which is more accurate and scientific than the prevalent Gregorian calendar.
On 14 February 1956, Dr. Saha died of a heart attack while on his way to attend a meeting of the Planning Commission.
Dr. Meghnad Saha was a strong nationalist with a searching, hard-working, dedicated and hard-working personality. His life was spent working in the service of science and the nation. Even today, the life of Shri Meghnad Saha is a source of inspiration for the dedicated and dedicated youth towards work.
