history of science and technology in india
The knowledge of India is rooted in the Vedas. The description available in the Vedas gives information about our rich culture and rich knowledge. What we call science today is contained within our knowledge. Some prominent scientists of the ancient modern period

1. Varaha Mihir - He was probably born in the year 499. He expressed the idea for the first time that there is a force that holds things together with the earth. He has written the book of astrology 'Panch Siddhantika'. His book 'Brihadwarahi Samhita' is considered to be the main basis of astrology.
2. Brahma Gupta He was born in Gujarat in the year 518. He first explained the rules for using zero. Worked on numerical analysis, a branch of higher mathematics. Explaining the difference between algebra and arithmetic, he considered two branches of mathematics. Explaining Varahamihira's point, he said that the earth, due to its nature, attracts objects towards it. He has two texts - Brahmasphuta Siddhanta and Khand Khadak.
3. Dr. Homi_Jahangir Bhabha - Dr. Homi-Jahangir Bhabha, was born on 30 October1909 in Mumbai. Dr. Bhabha went to Cambridge University to study engineering. He received his Ph.D. degree from Cambridge University in 1934. Dr. Bhabha gave a new direction to experiments in the field of electronics, space science, astronomy. Wrote works named Quantum Theory, Elementary Physical Particles and Cosmic Radiation. Dr. Bhabha died in a plane crash on January 24, 1966.
4. Dr. Shanti Swaroop Bhatnagar - Dr. Shanti Swaroop Bhatnagar was born on February 21, 1894 in Sahpur district of Punjab. In the year 1913, he passed the FSC examination in first class, he invented the methods of removing odorless wax, kerosene and cleaning petrol. The first book on magnetic chemistry was published in 1941. In 1943 he was elected a member of the Royal Society. The Government of India honored him with the title of Padma Bhushan. He died on 1 January 1955.
5. Dr. Prafulla Chandra Rai The great chemist Dr. Prafulla Chandra Rai was born on 2 August 1861 in East Bengal. In 1887, he received his degree in D.S.C. from the University of Edenburgh. From 1889 to 1916, he was a professor at the Presidency College, Kolkata. In 1896, a substance called mercurous nitrate was created. His important contribution to chemistry is the determination of the conductivity of mercury nitrates and their derivatives, bitrites. Dr. Rai died on 16 June 1944.
6.Dr. Vikram Sarabhai - Dr. Vikram Sarabhai was born on 12 August 1919 in Ahmedabad, Gujarat. He passed the BA examination in Mathematics and Physics from Cambridge University, London in 1940. He earned his PhD in 1947 from the University of Cambridge by researching the mysterious cosmic rays coming from the depths of space. In 1961 he became a member of the Atomic Energy Commission of India. Dr. Sarabhai became a member of the International Council of Scientific Union in the year 1966. In 1971, he was the head of the Department of Science in the United Nations Council. He died on 30 December 1971 at Thumba near Trivandrum.
7. Dr. Satyendranath Basu - Dr. Satyendranath Basu was born on January 1, 1894 in Kolkata. Dr. Satyendranath Basu passed the first class MSc examination in Physics from Kolkata • University in 1915 AD. Worked with Madame Curie from 1924 to 1925 AD. Doctor.
Basu. developed a mathematical explanation of the behavior of boson particles called the Bose-Einstein statistics. He made it possible to divide the atomic particles of nuclear physics into two parts only through his research work. Which are known as bosons. Initially, all science papers and magazines refused to print his research paper based on boson particles. Later Albert Einstein was influenced by his research paper and both did research work together from 1925 to 1926. On the basis of his theory, the God particle, which was discovered in the General Laboratory of Geneva, has been named Hings boson particle after Peter Hings and Satyendranath Basu. He died on 4 February 1974.

8. Jagdish Chandra Basu, - He was born on 30 November 1858 in East Bengal (now Bangladesh). He died in 1937. He gave the 'theory of consciousness power in vegetation' to the country and the world and made an instrument called 'crescograph' to check this power and vibration. Jagdish Chandra Basu is the inventor of the 'wireless wire' theory. Basu had publicly demonstrated the device in 1895, a year before Marconi patented his invention. This fact has now been accepted by western scientists as well. He was the first to make such a device that emitted subtle waves. Basu is the first person to use microwave to understand the structure of matter. His instrument is called 'Waveguide'. Special contribution was made in the development of new branch of science "Biophysics".
Name the inventors of the following inventions
1. Cresco_graph - Jagdish_chandra_basu,
2 Genetic codes and artificial genes - Hargobind Khurana
3 Raman Effect, Theory of Crystals - Chandrasekhar Venkataraman
4. The scattering of light in matter - Ramanathan
5. Gobar Gas Plant - Dr. C. B. D.
