National Science Day 2022: Speech and essay ideas to mark the discovery of the Raman effect by Sir C. V. Raman

National Science Day is celebrated annually in India on this day to mark the discovery of the Raman effect by Indian physicist Sir C. V. Raman on 28 February 1928. For his discovery, Sir C.V. Raman was awarded the Nobel Prize in Physics in 1930. It is celebrated to spread a message about the relevance of science in everyday living. It is observed by discussing various concerns and implementing new technology for scientific advancement.

This year, the theme of National Science Day is Integrated Approach in S&T for Sustainable Future.

On National Science Day, here are easy speech and essay ideas for students.

  1. Good Morning,

Honourable guests and my dear friends, I am extremely honoured to speak before this honourable gathering about the ‘National Science Day’.

Every year on February 28 we celebrate this day to mark the invention of the ‘Raman Effect’. However, do you know what it is and why the government have dedicated a day? Raman Effect also known as Raman scattering was an important discovery in the field of 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. He was also awarded Nobel Prize in 1930 in Physics for this important discovery.

National Science Day promotes science and technology and its feasibility in our daily life. It also encourages scientists, writers, students, and others who are involved in the promotion of science and technology. The day must be observed with the same diligence every year. It should not be limited only to the science fraternity but also must have participants from various walks of life.


2. India celebrates National Science Day on 28th February to commemorate the discovery of the ‘Raman Effect’ by a great Indian scientist Dr. Chandrasekhar Venkata Raman or C.V. Raman. He had invented the Raman Effect on 28th February 1928.

Raman Effect was an important discovery in the field of 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. The discovery was made by Sir C.V. Raman on 26th February 1928. He was also awarded the 1930 Nobel Prize in Physics for this important discovery. It is to commemorate Sir C.V. Raman and his discovery, the ‘Raman Effect’ that we celebrate National Science Day.

The first National 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 (NCSTC), requested the government in 1986, to designate February 28th as the National Science Day. Hence, beginning from 1987, National Science Day is observed every year in Indian schools, colleges, universities, and other relevant places.

One of the main events of the day includes ‘National Science Popularization Awards’ handed over to the people and also institutions for outstanding contribution in the field of science or for the popularization of science and communication. Several activities like debates, talk shows, science exhibitions, etc. are held to celebrate National Science Day.


3. It is a great pleasure to talk on this day – the National Science Day.

National Science Day is celebrated in India every year on the 28th of February. But why do we celebrate this day? What is the aim of it? This day commemorates the invention of the Raman Effect by the great Indian physicist, Sir Chandrasekhara Venkata Raman. It was on this same day that Sir Raman made to the world his greatest invention, the Raman Effect, in the year 1928. He was awarded and honored in the year 1930 with the Nobel Prize in Physics for his great success in the field of science in India.

On this day, we show our dignity and respect to the famous Indian physicist to mark his discovery of the Raman Effect. CV Raman was born on the 7th of November 1888 at Tiruchirappalli, Tamil Nadu. His father was a lecturer in Physics and Maths. Raman was the first person to research such an invention in India. He worked from 1907 to 1933 in Kolkata at the Indian Association for the Cultivation of Science, doing research on so many topics in Physics, of which the Raman Effect became his great success. His discovery marked a notable achievement in Indian history.

So, what is Raman Effect? It is the effect of the scattering of light when passing through different materials.

The day is celebrated as a science carnival, recognizing the scientific activities and programs in the country through the participation of students from schools and colleges, along with scientists from the state and national faculties. These events organized during this National Science Day celebration provides a platform for various newcomers/scientists to start their career in the field of science.

The main objectives of celebrating this National Science Day is to bring awareness to people about the importance of scientific applications in their daily life and to encourage them by popularizing Science and Technology. It allows the scientists and experts from the field to discuss issues and new technologies trending in the field. Also, the celebration is aimed at giving an opportunity for a younger generation to display their activities, efforts, and achievements in the field of science for human welfare.

Former West Bengal Assembly deputy speaker and Trinamool Congress leader Asish Banerjee was found dead at a party office next to his residence in Rampurhat, Birbhum district, on Sunday morning.

Police said his body was found hanging and was sent for postmortem. A large crowd gathered outside the Trinamool Congress office after news of his death spread.

Who was Asish Banerjee?

Asish Banerjee had served as the deputy speaker of the West Bengal Assembly when Trinamool Congress chief Mamata Banerjee was the state’s chief minister. He was also a five-time MLA from Rampurhat.

He had served as Bengal’s education and agriculture minister after Mamata Banerjee’s Trinamool Congress first came to power in the state.

Banerjee contested the West Bengal Assembly election earlier this year but lost the Rampurhat seat to BJP’s Dhruba Saha.

Asish Banerjee’s recent party role

Banerjee stepped down as chairman of the Trinamool Congress’s Birbhum district core committee in June. At the time, he said he would continue as a general member of the party.

He lived in the Hattalapara neighbourhood of Rampurhat, with the party office where his body was found located next to his house.

BJP gains in Birbhum

The BJP won six of the 11 Assembly constituencies in Birbhum in the latest state election. This marked a significant change from 2021, when the Trinamool Congress had won 10 seats in the district while the BJP had secured one.

Police have sent Asish Banerjee’s body for postmortem as the circumstances surrounding his death are being investigated.

Congress president Mallikarjun Kharge and Leader of Opposition in the Lok Sabha Rahul Gandhi skipped the 80th Independence Day celebrations at Delhi’s Red Fort for the second consecutive year.

Prime Minister Narendra Modi led the Independence Day celebrations at the historic venue on Saturday.

The absence of the two senior Congress leaders comes amid strained relations between the ruling party and the Opposition, which further deteriorated during the Monsoon Session of Parliament that concluded on Thursday.

2024 seating controversy

Rahul Gandhi had attended the Independence Day celebrations in 2024 but his seating arrangement triggered a controversy. The Congress leader, who holds the status of a Cabinet minister as Leader of the Opposition in the Lok Sabha, was seated in the second-last row during the ceremony at the Red Fort.

The Opposition had criticised the seating arrangement, calling it an insult to the people. The Defence Ministry, which organised the event, said the arrangement had been modified to accommodate Olympians at the venue.

According to protocol, the Leader of the Opposition is seated in the front row during ceremonial events.

Opposition-ruling party tensions

Relations between the government and the Opposition remained tense during the Monsoon Session, which ended on Thursday.

The session saw repeated clashes between the two sides, with both the Opposition and the ruling party blaming each other for the low productivity of Parliament.

The session began on July 20, with students marching towards Parliament on the first day. Twelve bills were passed during the session, while detailed discussion took place on only one legislation, concerning paper leaks.

The Congress, along with the Trinamool Congress and Samajwadi Party, also boycotted the customary tea party hosted by Lok Sabha Speaker Om Birla after the House was adjourned sine die.
