Today is the birthday of the great scientist CV Raman. Raman, the first Indian to win the Nobel of Science, was born on 7 November 1888 in the Madras Presidency. CV Raman proved that when a ray of light passes through a transparent object, its wave length (wavelength) changes. This is called the Raman effect. He was awarded the Nobel Prize for Science in 1930 for his invention. Sir CV Raman was awarded the Bharat Ratna in 1954 for his contribution in the field of science.
Raman joined the post of Assistant Accountant General in 1907, but science was always his first love. He used to keep doing his research by reaching the laboratory somehow. He left a government job in 1917 and became a professor of physics at Calcutta University. It was here that on 28 February 1928, he along with other scientists including KS Krishnan discovered the Raman effect. This is the reason that this day is celebrated every year in India as National Science Day. CV Raman died in 1970 at the age of 82.
Raman effect is still being used in many places. When Chandrayaan-1 announced that there was water on the moon, Raman spectroscopy was also amazing behind it. The Raman effect is also proving to be quite useful in forensic science. It has now become easier to find out what events happened when and how.
The only woman scientist to win 2 Nobel Prizes: Marie Curie
Nobel Family: Marie and Pierre Curie with their daughter Irene.
Marie Curie, Madame Curie, was born on 7 November 1868 in Warsaw, Poland. Both parents were teachers, due to which the atmosphere of education was found. When she went to Paris for further studies, she met Pierre Curie there. While working in Pierre Curie’s lab, their friendship turned into a relationship and on 1895 they both got married.
Marie Curie is the only woman to have won the Nobel Prize twice. Physics in 1903 and Nobel Prize in Chemistry in 1911. She discovered radio activity with her husband, for which she received the joint Nobel Prize in 1903. Unfortunately, a year later, Pierre Curie died in an accident. Marie Curie taught at the University of Paris and won her second Nobel Prize in Chemistry in 1911 for the purification of radium and the discovery of polonium.
He died on 4 July 1934 after suffering from aplastic anemia due to exposure to radiation. The special thing was that Marie Curie’s daughter Irene also won the Nobel Prize in Chemistry in 1935.
These events are considered important in India and the world on 7 November:
