National Science Day ,2021

ABOUT NATIONAL SCIENCE DAY

National Science Day is celebrated all over in India with great enthusiasm on 28th of february every year to commemorate the invention of the Raman Effect ( it involved vibrational energy being gained by a molecule as incident photons from a visible laser are shifted to lower energy.) in India. 

The inventor of Raman Effect is the great indian physicist Sir Chandrasekhara Venkata Raman . He was awarded and honoured with the Nobel Prize in physics in the year 1930 for his great success in the field of science. 

HISTORY BEHIND SCIENCE DAY

National science day is observed by India. In 1986 The  National Council  for Science and Technology Communication ( NCSTC) asked the government of India to declare the National Science Day on February 28.

In 1987 NCSTC declared the institution of national science to recognised C. V. Raman for the best effort in the field of science for communication and similar.

ABOUT RAMAN EFFECT

Raman Effect is a change in the wavelength of light ,can be seen when a light transmit is deflected by molecules. When a broadcast of light crosses a dust-free, transparent sample of a chemical compound, a small bit of the light emerges in directions other than that of the event broadcast.

The Raman effect was declared a National Historic Chemical Landmark by the American Chemical Society in recognition of its significance as a survey for the composition of liquids, gases, and solids.

ABOUT SIR CHANDRASEKHAR VENKATA RAMAN

Sir chandrasekhara venkata raman was an indian physicist who has a bigger hand for invented raman effect is a light scattering. He was born on 07 november 1888 in Thiruvanikoil, a neighborhood city of Tiruchirappalli in Tamil Nadu, India.

He was formerly known as C. V. Raman. He is highly educated with presidency college and has been honoured with many awards such as Bharat Ratna, Nobel Prize in physics, Hughes Medal, Lenin Peace Prize, Franklin Medal, and many more. 

His parent’s R. Chandrasekhar lyer and parvathi ammal and spouse Lokasundari Ammal. C.V. Raman is known for his research of Raman effect and has done work in many science institutions.

IMPORTANCE OF NATIONAL SCIENCE DAY

National science day is a day to recognise the efforts of a great physicist who has given us the Raman effect a wavelength of light on 28 february,1928. All over the country celebrated the national science day. 

In this modern era, people have bounded with the technology of science. Many things invented by science which are used in our daily life or become an important part of our lives.

As there is a saying that “one invention of science can change the world forever. So we all know very well that science has given us to a lot of things and technologies  since 16th century ie. the computer, the steam engine, printing press, internet, the light bulb, penicillin, electricity, vaccines ,good anti- cancer drugs, automobiles, and many more.

Because of the technology of science, life has become easier and simpler for humans. Science is having a major influence on our daily life. India has an important role for contributing to the scientific world from the ancient time. The scientists make it possible with their research and the upgradation of technologies.
