National Science Day is observed in India on February 28th every year to commemorate the discovery
'Raman Effect' by Sir C.V. Raman or Dr Chandrasekhar Venkata Raman in 1928. Sir C.V. Raman
the 1930 Nobel Prize in Physics for this discovery.
HISTORY OF WHY NATIONAL SCIENCE DAY IS CELEBRATED
On February 28th, 1928, one of the greatest Indian physicists,Sir C.V. Raman ,
novel discovery on the scattering of light, which came to be known as the 'Raman
was a very important discovery that earned him a Nobel Prize in 1930. The first
Science Day was celebrated in 1987 . Nearly six decades after Sir C.V.
Raman made the
important discovery , the National Council for Science and Technology Communication
requested the government in 1986 to designate February 28th as National Science Day. Hence,
beginning in 1987, National Science Day has been observed every year in Indian schools,
colleges, universities, and other relevant places.
CELEBRATION OF NATIONAL SCIENCE DAY
National Science Day is widely celebrated throughout the nation. Schools and colleges
participate with utmost zeal and enthusiasm. Mainly, in engineering and science colleges,
exhibitions are held, and students discuss the development and use of science and
technology. Government also hands out commemoratory awards and monetary prizes to the
individuals and organisations involved in promoting science and technology in some way or

ABOUT RAMAN EFFECT
The Raman Effect was an important discovery in the scattering of light.
The discovery states
that when the light traverses through a transparent object, some of it gets dispersed, and
the dispersed light changes its wavelength and amplitude, though slightly. Sir C.V. Raman
was discovered on February 28th 1928. He was also awarded the 1930 Nobel Prize in Physics
for this important discovery. We celebrate National Science Day to commemorate Sir C.V.
Raman and his discovery, the 'Raman Effect.
ABOUT SIR C.V RAMAN (OR DR. CHANDRASEKHAR VENKATA RAMAN)
Chandrasekhar Venkata Raman, popularly known as C.V. Raman, was born in Tiruchirapalli in
Tamil Nadu, in November 1888. He was the second child of Chandrasekhar Iyer and Parvathi
Ammal. His father was a lecturer in Mathematics and physics, so even from his early years,
Raman was immersed in an academic atmosphere. At a very young age, Raman moved to
Visakhapatnam in Andhra Pradesh. On May 6, 1907, he married Lokasundari Ammal.
Raman grew up in an atmosphere of music, Sanskrit literature and science. He completed
secondary school education at 11 and moved to the prestigious Presidency Colleges
1904, when he was fifteen, he received his B.A. Honours in Physics and English. He
M.A. degree in 1907, obtaining the highest distinction. On completion of their studies,
Raman served as an accountant under the Department of Finance of the Indian government.
was elected to the Royal Society of London in 1924. At Raman's graduation, there were
opportunities for scientists in India. This forced him to accept a position with the
Civil services as an Assistant Accountant General in Calcutta. His love for science,
enthusiasm for work and curiosity about learning new things made him immensely
the study of sound. When he was eighteen, one of his first research papers were
the 'Philosophical Magazine of England. Later another paper was published in the
journal 'Nature. He served as a Professor of Physics at the University of Calcutta from
till 1948. He then took over as the Director of the Raman Institute of Research at
Bangalore, founded and endowed by himself. He was awarded the Nobel Prize in Physics for
discovery of 'Scattering of Light' famously known as 'The Raman Effect. Sir C.V. Raman
remembered for his major contributions in the field of vibration and sound, musical
instruments, ultrasonic, diffraction, metrological and colloid optics photo-electricity,
x-ray diffraction, magnetism, dielectrics and the Raman Effect. Sir. C.V. Raman started
contributing to science even at 18 by publishing his inventions and discoveries in
international magazines like 'Nature'. He started the first Indian Scientific Research
Institute to promote scientific investigation among Indians.
Honours and Awards Raman received many honours from all over the world for his
achievement. In 1928 the Science Society of Rome Awarded him the Matteucci Medal. The
British conferred the knighthood in 1929, and from then on, he came to be known as
Sir C.V. Raman. The following year he was honoured with the prestigious Hughes medal
the Royal society. Honorary Doctorate degrees were conferred on him by the universities
Freiburg (Germany), Glasgow (England), Paris (France), Bombay, Benaras, Patna, Mysore,
several others. In 1930, the Swedish Academy of Sciences chose Raman to receive the
Prize for Physics. He was the first Indian, more precisely, the first Asian to have
this award in his days. He was appointed Director of the Tata Institute in Bangalore in
1933. The Tata Institute soon became famous for the study of crystals. Raman and
Nagendranath elegantly explained the diffraction of light by ultrasonic waves in a
This became known as the 'Raman –Nath Theory'. To encourage scientific research in
Raman established the Academy of Sciences in 1934. Since that year, the science journal
Proceedings of the Academy has been published every month till date. The Executive
of the Academy named the centre 'Raman Research Institute' in 1948, and he became the
Director of the Institute.
SPECIAL EVENTS AND ACTIVITIES ON NATIONAL SCIENCE DAY
One of the main events of National Science Day includes the 'National Science
Awards' handed over to the people and institutions for outstanding scientific
or the popularisation of science and communication. Activities like debates, quiz
competitions, talk shows, science exhibitions, etc., are held to celebrate National Science
Day. Science fairs and exhibitions are held to promote science and innovations .
and journals on science and technology are published and promoted. Monetary awards
handed over to individuals and institutions promoting science. The greatest honour that the
Government of India conferred on an Indian is the Bharat Ratna award. Raman became a 'Bharat
Ratna' in 1954. CV Raman is the uncle of Nobel laureate and Physicist Subrahmanyan
SIGNIFICANCE OF NATIONAL SCIENCE DAY
Celebration of National Science Day is very important in promoting theInstitution of
