The 2023 Nobel Prize in Physics has been awarded to Pierre Augustini, Ferenc Crouse and Ann Hullier. The committee has given him this title for his study on electrons. This award was given for the experimental methods in which attosecond pulses of light were generated to study the mobility of electrons in matter.
Anne Hullier has become the fifth woman to win Nobel in the field of Physics. Till now, 119 people have been awarded this title in the field of Physics. Earlier on Monday, i.e. on October 2, Caitlin Carico and Drew Weissman received the Nobel Prize in Medicine. Prize distribution will last for a week.
After this, the winners of Chemistry will be announced on 4th October. The prize in literature will be given on 5th October. The Nobel Peace Prize will be announced on 6 October. After this, the winners in Economic Science will be announced on October 9.
Now let us know about Nobel Prize in Physics
On 27 November 1895, Alfred Nobel signed his last will and testament. With this, he gave the largest part of his will to a series of awards, the Nobel Prize. The Nobel Prize is given in the fields of Physiology, Medicine, Physics, Chemistry, Literature, Peace and Economic Sciences.
According to Alfred’s will, the Physics Nobel Prize should be awarded to the person who would have made the most important discovery or invention in the field of physics. A total of 116 Nobel Prizes have been awarded in Physics from 1921 to 2022. Physics Nobel Prizes were not awarded in 1916, 1931, 1934, 1940–41 and 1942. This decision was taken by the Nobel Foundation. According to Nobel Foundation rules, if any discovery or invention does not meet the set criteria, then the prize money is kept reserved till the next year. Fewer Nobel Prizes were awarded during World War One and World War II.
India’s CV Raman has received the Physics Nobel Prize.
Sir Chandrashekhar Venkata Raman, one of India’s most distinguished scientists, received the Physics Nobel Prize in 1930. In 1928, CV Raman proved that when a ray of light passes through a transparent object, a change in its wavelength is visible. He gave his own name to this invention, which is called Raman Effect. He was given the Physics Nobel Prize for this invention.
CV Raman was born on 7 November 1888 in Tiruchirappalli, South India. Raman worked as an Assistant Accountant General in 1907, but science was always his first love. Somehow or the other he kept reaching the laboratory and doing his research. In 1917, he left the government job and became Professor of Physics at Calcutta University. It was here on 28 February 1928 that he, along with other scientists including KS Krishnan, discovered the Raman Effect. This is why this day is celebrated as National Science Day every year in India. Raman was awarded the Bharat Ratna in 1954 for his contribution in the field of science.
Raman effect is still being used in many places. When Chandrayaan-1 announced the presence of water on the Moon, the reason behind it was Raman spectroscopy. Raman effect is proving to be very useful in forensic science also. Now it has become easy to find out which event happened when and how.
