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.

PM Modi accuses Congress of anti-Sikh bias over Rahul Gandhi’s ‘traitor’ remark

Prime Minister Narendra Modi accused Rahul Gandhi of targeting BJP MP Ravneet Singh Bittu with a ‘gaddar’ remark because of his Sikh identity while speaking in the Rajya Sabha.

PM Modi

Prime Minister Narendra Modi on Wednesday launched a sharp attack on Leader of the Opposition Rahul Gandhi, alleging that his “traitor” remark against BJP MP Ravneet Singh Bittu reflected the Congress party’s animosity towards the Sikh community.

The Prime Minister made the remarks in the Rajya Sabha while replying to the motion of thanks on the President’s address. Referring to an incident in the Parliament complex a day earlier, Modi said Gandhi’s comment had crossed all limits of political decency.

The controversy stems from a protest by suspended Opposition MPs, during which Ravneet Singh Bittu — a former Congress leader who joined the BJP ahead of the 2024 Lok Sabha elections — allegedly made a remark suggesting the protesters were behaving as if they had won a war.

In response, Rahul Gandhi was heard saying, “A traitor is walking by, look at his face,” before approaching Bittu and extending his hand. Gandhi then reportedly added, “Hello, brother. My traitor friend. Don’t worry, you will come back.”

Bittu refused to shake hands with the Congress leader and instead described him as an “enemy of the country” before walking away from the scene.

While the Congress later clarified that Gandhi’s remark was aimed at Bittu for leaving the party, the BJP seized upon the comment, calling it an insult to the Sikh community. Protests were subsequently held by members of the Sikh community outside the Congress headquarters and at other locations.

Addressing the House, Prime Minister Modi said that many leaders had quit the Congress in the past and that the party itself had split multiple times, but none of those leaders had been labelled a traitor. “He called this MP a traitor because he is Sikh,” the Prime Minister alleged, as treasury bench members raised slogans condemning the remark.

The Manipur Legislative Assembly will convene at 4 pm on Thursday in Imphal, a day after Yumnam Khemchand Singh was sworn in as the chief minister. A floor test is likely to be held on the first day of the session to establish the majority of the newly formed government.

In the 60-member Assembly, the BJP holds 37 seats, while its ally National People’s Party has six members, giving the ruling combine a clear majority in the House.

Singh chaired the first Cabinet meeting of his government late Wednesday evening, shortly after taking oath as the 13th chief minister of Manipur. The meeting marked the formal start of administrative functioning under the new Council of Ministers.

His appointment came nearly a year after the resignation of former chief minister N Biren Singh, who stepped down following months of ethnic violence between the Meitei and Kuki communities in the state.

After taking oath, Singh thanked Prime Minister Narendra Modi and said he would work with “utmost diligence to advance development and prosperity in Manipur,” aligning the state’s efforts with the vision of Viksit Bharat.

He said the government’s focus would be on inclusive economic growth while preserving Manipur’s cultural heritage, adding that he would discharge his responsibilities with sincerity and dedication, mindful of the trust placed in him.

The summoning of the 12th Manipur Legislative Assembly by Governor Ajay Kumar Bhalla, along with the first Cabinet meeting, signals the resumption of legislative and administrative processes in the state, officially bringing President’s rule to an end.

The sixth session of the 12th Manipur Legislative Assembly was last held from July 31 to August 12, 2024.

PM Modi skips Lok Sabha reply as protests force repeated adjournments

PM Modi did not deliver his Lok Sabha reply today after sustained Opposition protests led to repeated adjournments over a dispute involving Rahul Gandhi’s proposed speech.

PM Modi

Prime Minister Narendra Modi did not deliver his scheduled reply to the Motion of Thanks on the President’s address in the Lok Sabha today after sustained Opposition protests led to multiple adjournments of the House.

The disruption followed an escalation of tensions linked to Congress leader Rahul Gandhi’s proposed speech and the suspension of eight Opposition MPs a day earlier. The situation worsened after remarks made by BJP MP Nishikant Dubey during the proceedings.

Dispute over references to books sparks fresh ruckus

The controversy intensified when Nishikant Dubey responded to Rahul Gandhi’s demand to speak on national security and references to the unpublished memoirs of former Army chief General MM Naravane. Dubey said that while Gandhi wanted to quote from an unpublished book, he himself had brought several books that, according to him, made claims about the Gandhi family.

As Dubey began listing these books and their contents, strong protests erupted from Opposition members. Krishna Prasad Tenneti, who was presiding over the House at the time, cited Rule 349, which restricts members from reading out books, newspapers, or letters unless directly related to parliamentary business. Despite repeated warnings, the matter remained unresolved, leading to another adjournment.

Rahul Gandhi accuses government of silencing debate

Earlier in the day, Rahul Gandhi alleged that he was being prevented from speaking on an issue of national importance. He claimed the government was uncomfortable with references to General Naravane’s memoirs, which he said discussed the handling of the 2020 China border crisis.

In a social media post, Gandhi said he intended to present the Prime Minister with a book authored by the former Army chief, adding that some cabinet ministers had even questioned the existence of the book. He also wrote to Lok Sabha Speaker Om Birla after the suspension of eight Opposition MPs, alleging that parliamentary debate was being curtailed.

After it became clear that the Prime Minister would not speak in the House today, Gandhi posted that PM Modi had avoided Parliament because he was “scared” to face the truth. Congress MP Priyanka Gandhi Vadra echoed the allegation, claiming the Prime Minister was unwilling to enter the House.

Proceedings disrupted throughout the day

Lok Sabha proceedings were first adjourned until 2 pm amid loud protests over the issue linked to Naravane’s memoirs. Even after the House reconvened, disruptions continued, preventing normal business from resuming.

Later, Congress MPs staged a demonstration outside the Parliament complex, demanding that Rahul Gandhi be allowed to speak on the President’s address.
