India, birthplace of great intellects
India is a land of many intelligent people who have made several inventions from the past. The people of India introduced the numeral system and the system of geometry. Indians were great mathematicians. In the same way, they have made many inventions and discoveries in the past but probably could not preserve their talent. There are many scientists in India who have made different inventions. The Indian scientists have played a major role towards economic progress and social progress of the nation.
Scientists in India are divided into ancient and modern scientists. Some of the names that are included among ancient are Aryabhata, Chanakya, charaka, Jayadeva, etc. the modern scientist include C.V. Raman, C.R. Rao, Birbal Sahni etc. the ancient scientists existed since human civilization was not fully into existence and India had not made any progress in technology. the modern scientists as named above exist from the pre-independence or post-independence period. Indian scientists have contributed to the world in various areas such as astronomy, anthropology, physics, biology, Space research, ethnology, etc.
Renowned scientists of India
C.V.Raman: C.V. Raman is one of the most eminent scientist of India who is known to the world for the theory of light refraction and optics. He was born on November 7, 1888 in the state of Tiruchinapally in Tamil Nadu. He is the first person to receive a noble prize retaining his Indian citizenship. He passed out as a gold medalist for physics from Presidency college in 1904. At the early stage of his career he did not start experimenting or aim to be a scientist because he could not earn money instantly. So he joined a finance department and started his experimentation in his laboratory after his office hours. He worked in the field of optics. After ten years, he became the professor of Calcutta University. His discovery and contribution towards the theory of refraction of light and optics received a lot of recognition and he was nominated by the Royal Society of Britan in 1924. He later became the directors of the Institute of Sciences of Bangalore and then he conducted many experiments such as wave theory of ultrasonic, hypersonic and studied the theory of frequencies more deeply. He also studied about vibrations and their applications with x-rays etc. This great scientist passed away in 1970.
Jagdish Chandra Bose: This great scientist was known for his invention of wireless telegraphy. Everybody in our nation know that he was the first person who discovered that the plants around us have life observing their growth periodically like the other living creatures. He had a inquisitive set of mind from his childhood days and always questioned his teachers and father. He was born in Mymensingh in 1858 on November 30. His completed his schooling in a village and attained a bachelors' degree in physical science at St. Xavier's college in 1879. He also aimed to be a doctor in between as he studied a degree of medicine in London. But he did not continue because he could not cope up with his own health. He became the lecturer in Presidency college and spent his time on research. He studied the various theories such as diffraction, refraction and continued his research on metals some years. Later he prioritized his study on plants. He started arguing that plants too have life and invented a meter that could record the growth of plants. He died in 1937 with a lot of valuable contribution towards science.
M.Vishweshwarayya: He was basically an engineer by profession who invented the strategies to control the wasted water from the dams. He was born in Muddenhalli in Kolar district in a poor family. His father who was a Sanskrit scholar and practiced ayurveda passed away when the scientist was only 15 years old. He studied in engineering in Poona and was ranked first in 1883. He became the Diwan of Mysore in 1912 when he tirelessly started working for the industrial progression. He introduced many important industries in the country such as Soap factories, Chromme tanning factory etc. As a Deewan he led a life of simplicity. He led a very healthy lifestyle throughout his life. He introduced a block system to prevent the waste water from the dams from flowing. He introduced steel doors to block the water.
A.P.J.Abdul Kalam: this figure in India is known to everyone because he became the president of India from 2002 to 2007 being a nuclear scientist despite the controversy. His rule in India was admired by all the people. He was born on October 15, 1931 in Tamil Nadu. He has received a doctorate degree from at least 30 universities in India. As a scientist he has worked for the nuclear weapon technology and aims India to be a superpower. He is always said to be a man of vision whose mind is always occupied with constructive ideas.
Kalpana Chawla She is the first woman in India who entered the field of Indian aeronautics and unfortunately was killed in the Space Shuttle event in 2003. In the year 1982 he earned a M.S. degree in aeronautic engineering and later on completed a Ph.D. degree. She is the first Indian woman to fly on space. This great woman contributed tirelessly for microgravity. She received many recognition after her death such as Congressional Space Medal of Honor, NASA Space Flight Medal etc.
