National Science Day – 28th February

National Science Day is celebrated in India on February 28 each year to mark the discovery of C.V. Raman. The episode is venerated in honor of Sir C.V. Raman for his bequest and discovery of the Raman consequence on February 28, 1927, for which he was, rewarded the Nobel Prize in 1930. On that day in 1928, Sir C.V. Raman proclaimed the innovation of the Raman Effect. For this, he was granted the Nobel Prize for Physics in 1930.

The day is celebrated in India to mark the discovery of the Raman effect by Indian physicist Chandrashekhara Venkata Raman on the same day in 1928.

Key Facts

The Raman Effect led to the escalation of a new discipline, Raman Spectroscopy, which has now urbanized into an influential tool for an extensive variety of precise investigations and business applications. He takes the credit of the first noble prize winner from India. Even today there are so many across the globe extracting exciting new results from his discoveries. The impact of Raman’s effect can be felt in every field of science. It has played a significant role in the field of spectroscopy, medical diagnostics and material characterization.

Under the Ministry of Science and Technology, Rashtriya Vigyan Evam Prodoyogiki Sanchar Parishad which is also known as National Council for Science & Technology Communication conducts various events and programs on science related topics. The celebration is not confined to any particular area for it takes place throughout the country.

This day gives us an opportunity to thank all the scientists for their remarkable contributions and dedication in this field. Hence the National Science Day holds great significance for Indian Science and scientific community. There are science exhibitions and fairs conducted all over the country where even the visitors can interact with the science fraternity and perform science-based experiments and activities for the mutual benefit.

Apart from this even colleges and schools on the National Science Day conducts activities like debates, quiz competitions, exhibitions, lectures,etc.The celebration of this day is of great motivation to the upcoming generations. The National Science Day also accelerates the pace of development in science and its related field. Every year a different theme is selected and all the forth programmes and activities are based around that theme.

Nowadays Science has reached a better level by which every people are used to get many types of Facilities and Services with the help of development in the Science and technology. National Science Day is used to make the people develop every activity with great dedication and idea to perform the activity well for the better future of the people.

New 2018 National Science Day Theme is “Science and Technology for a sustainable future.”

One has to come forward to make some technology for the people to get every kind of facility and services to develop any activity accurately for the welfare of the people.

Dr. Chandrashekara was a great Scientist and used to dream about making a developed Nation for the people to come up from many Countries. He made many innovations by which every people are used to get something unbelievable for their future growth.

He received many ideas and plans from the young Children and also from the experienced person to build a superior technology to develop the infrastructure of the India Country. He used to gather every knowledge from his Teachers and also from many technological Books to gain much of the knowledge to build a Strong and Wealthy Nation.

National Science Day is used to celebrate in many Colleges, Universities, Schools, Researchers, Scientists, Educational Institution, Medical, Technical, etc in India. There was a National Council for Technology and Science Communication in India which serves for the betterment of the people.

There are many research centers in India by which researchers can carry their tasks with the help of many Research Centers. Many people are curious to develop the Nation in a better manner.

There are many kinds of research activities developed in India by which people are used to getting every kind of Facility and Services by which they can get to know every idea and plans to cultivate a better life for the people.

Raman Effect

 National Science Day

Raman scattering or the Raman effect is the inelastic scattering of a photon by molecules which are excited to higher vibration or rotational energy levels. It was uncovered by C. V. Raman and K. S. Krishnan (who was a student of C.V. Raman) in liquids,and independently by Grigory Landsberg and Leonid Mandelstam in crystals. The effect had been forecasted theoretically by Adolf Smekal in 1923. Raman scattering is utilized as a tool to detect high-frequency photon and mag non excitation. Raman spectroscopy can be used to determine the power constant and connection duration for molecules that do not have an infrared absorption spectrum. Raman amplification can be used in optical amplifiers.
