Question

biography on Indian scientist​

Answer 1

Answer:

Science is an important part of our everyday life, even more so than we notice. From our fancy gadgets to the the technologies we can’t live without, from our humble light bulb to the space explorations, it is all gift of science and technology.

I wonder what would we be doing if none of these things were invented? How often do we take out the time to think about those extra ordinary minds who made life easier for us? Here is a list of 14 Indian scientists who achieved a global recognition

1. CV Raman
2. Homi J. Bhabha
3. Visvesvaraya
4. Venkatraman Radhakrishnan
5. S. Chandrashekar
6. Satyendra Nath Bose
7. Meghnad Saha
8. Srinivasa Ramanujan
9. Jagadish Chandra Bose
10. Vikram Sarabhai
11. Salim Ali
12. Har Gobind Khoran
13. Birbal Sahni
14. APJ Abdul Kalam

Answer 2

SIR C.V. RAMAN : -

He discovered that, when light traverses a transparent material, some of the deflected light changes in wavelength. This phenomenon is now called the Raman scattering and is the result of the Raman effect.

SIR HOMI J. BHABHA :-

He was the first person to become the Chairman of the Atomic Energy Commission of India. Having started his scientific career in nuclear physics from Great Britain, Bhabha returned to India and played a key role in convincing the Congress Party’s senior leaders, most notably Jawaharlal Nehru, to start the ambitious nuclear programme.

SIR VISVESVAYA :-

Sir M V suggested that India try to be at par with industrialized nations as he believed that India can become developed through industries.  He has the credit of inventing ‘automatic sluice gates’ and ‘block irrigation system’ which are still considered to be marvels in engineering.

SIR VENKATRAMAN RADHAKRISHNAN :-

His observations and theoretical insights helped the community in unraveling many mysteries surrounding pulsars, interstellar clouds, galaxy structures and various other celestial bodies.

SIR S. CHANDRASHEKHAR :-

His most celebrated work concerns the radiation of energy from stars, particularly white dwarf stars, which are the dying fragments of stars.

SIR SATYENDRANATH BOSE :-

Bose adapted a lecture at the University of Dhaka on the theory of radiation and the ultraviolet catastrophe into a short article called “Planck’s Law and the Hypothesis of Light Quanta” and sent it to Albert Einstein. Einstein agreed with him, translated Bose’s paper “Planck’s Law and Hypothesis of Light Quanta” into German, and had it published in Zeitschrift für Physik under Bose’s name, in 1924.

SIR MEGHNATH SAHA :-

He also invented an instrument to measure the weight and pressure of solar rays. He was also the chief architect of river planning in India. He prepared the original plan for the Damodar Valley Project.

SIR SRINIVASA RAMANUJAN :-

He had exhausted the mathematical knowledge of two college students who were lodgers at his home. He was later lent a book on advanced trigonometry written by S. L. Loney. He completely mastered this book by the age of 13 and discovered sophisticated theorems on his own.

SIR JAGADISH CHANDRA BOSE :-

His well known inventions is the crescograph, through which he measured plant response to various stimuli and hypothesized that plants can feel pain, understand affection etc.He was the first person to use semiconductor junctions to detect radio signals, thus demonstrating wireless communication for the first time.

SIR VIKRAM SARABHAI :-

He was instrumental in the setting up of the Indian Space Research Organization (ISRO), when he successfully convinced the Indian government of the importance of a space programme for a developing nation after the launch of the Russian Sputnik, in a quote.

SIR SALIM ALI :-

This was the Birdman of India who was the key figure behind the Bombay Natural History Society after 1947 and used his personal influence to garner government support for the organisation. He was awarded India’s second highest civilian honour, the Padma Vibhushan in 1976.

SIR HAR GOBIND KHURANA :-

Khorana shared the 1968 Nobel Prize for Physiology or Medicine with Marshall W. Nirenberg and Robert W. Holley for research that helped to show how the order of nucleotides in nucleic acids, which carry the genetic code of the cell, control the cell’s synthesis of proteins.

SIR BIRBAL SAHANI :-

He was elected a Fellow of the Royal Society of London (FRS) in 1936, the highest British scientific honor, awarded for the first time to an Indian botanist.  He was a founder of The Paleobotanical Society which established the Institute of Palaeobotany on 10 September 1946 and which initially functioned in the Botany Department of Lucknow University.

SIR A.P.J. ABDUL KALAM :-

Kalam was transferred to the Indian Space Research Organization (ISRO) where he was the project director of India’s first indigenous Satellite Launch Vehicle (SLV-III) which successfully deployed the Rohini satellite in near earth’s orbit in July 1980. Kalam advocated plans to develop India into a developed nation by 2020 in his book India 2020.
