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.

Arvind Kejriwal asks people to light diyas, not burst crackers ahead of Diwali

On October 14, Rai announced a ban on the production, storage, distribution, and use of firecrackers in the city until January 1, 2025.

Former Delhi Chief Minister and AAP national convener Arvind Kejriwal on Wednesday asked residents of the national capital to refrain from bursting firecrackers and light diyas in Diwali, noting that Deepavali is a festival of lights and not firecrackers.

Addressing a press conference, the former Chief Minister said, “Even the Supreme Court and High Court have said that, in light of the pollution, we should refrain from bursting crackers and instead light diyas. This is the festival of lights, not fireworks. It is not about doing anyone a favor. The pollution that occurs will impact our children, so this issue transcends religion. Every life is important.”

This statement comes amid rising air pollution in the national capital. Delhi’s air quality has worsened over the past several days, prompting the Delhi government to implement measures aimed at controlling air pollution, including a crackdown on firecracker usage.

Earlier, Delhi Environment Minister Gopal Rai has written to Lieutenant Governor Vinai Kumar Saxena, urging him to take strict action against violations of the firecracker ban in the national capital.

On October 14, Rai announced a ban on the production, storage, distribution, and use of firecrackers in the city until January 1, 2025.

In his letter, Rai expressed concern that, despite the ban, firecrackers were being openly sold in various markets in Delhi. He noted that these firecrackers were being transported across borders connecting Delhi to Haryana and Uttar Pradesh.

Rai indicated that the Delhi Police, as law enforcement agencies, appeared to be neglecting the directions to enforce the firecracker ban, allowing vendors to openly flout the restrictions.

As of Tuesday, a thin layer of smog covered the National Capital, with parts of Delhi’s air quality remaining in the ‘very poor’ category. The Central Pollution Control Board (CPCB) reported an Air Quality Index (AQI) exceeding 300 around 7:00 am. At Anand Vihar, for instance, the AQI reached 317, while Aya Nagar recorded an AQI of 312—both in the ‘very poor’ category. Jahangirpuri also had a high AQI of 308. In contrast, Chandni Chowk reported better air quality, at an AQI of 191, which is considered ‘moderate.’

Meanwhile, Delhi BJP leaders noted that 108 incidents of stubble burning were recorded in Punjab. They protested against Punjab Chief Minister Bhagwant Mann regarding air pollution concerns at Kapurthala House. A delegation of leaders sought a meeting with the Punjab Chief Minister to submit a memorandum but was unable to meet him.

RJD MP Manoj Jha says Election Commission has become part of agenda

In a letter to the Congress party, the Commission urged them to refrain from making unfounded claims after every election, accusing the party of creating generic doubts without substance.

RJD MP Manoj Jha said on Wednesday that the Election Commission of India has become a part of the agenda after the election body rejected the Congress allegations about irregularities in the recently concluded Haryana Assembly elections.  

Hitting out at the Election Commission, the Rajya Sabha MP said that the ECI must be the custodian of a free and fair election, not the custodian of any machine, not of any paper.

“Congratulations to the Election Commission for being included in the agenda. When the structure of Article 324 was conceived, it was not conceived in the form of a machine or paper custodian but in the form of a free and fair election,” he said.

He added, “If you have even 1% doubt, then what stops you from going back to the ballot? I would like to say that the Chief Election Commissioner, you are the custodian of a free and fair election, not the custodian of any machine, not of any paper.”

The RJD leader’s comment came after ECI rejected allegations made by the Congress party regarding irregularities in the recent Haryana elections, labelling them as baseless, misplaced, and devoid of facts.

In a letter to the Congress party, the Commission urged them to refrain from making unfounded claims after every election, accusing the party of creating generic doubts without substance.

The Election Commission of India has advised Congress to implement strict measures to prevent irresponsible allegations, especially during sensitive periods like polling and counting days. Such claims could lead to public unrest, turbulence, and chaos.

The ECI highlighted five specific cases from the past year and urged Congress, a national party with significant experience, to practice due diligence and refrain from making habitual, evidence-free criticisms of the electoral process.

After a thorough re-verification by returning officers of all 26 contested Assembly constituencies, the ECI wrote to Congress President Mallikarjun Kharge, confirming that every step in the Haryana electoral process was executed flawlessly and was monitored by Congress candidates or their agents.

In response to Congress’s concerns about the EVM battery display, the ECI clarified that the battery’s voltage and capacity do not affect the voting functionality or integrity of the EVMs.

“The battery status displayed on the control unit is solely for technical teams to monitor power levels, ensuring smooth operation during polling,” the ECI stated.

India, China complete disengagement in Depsang, Demchok at LAC after 4 years standoff

In a significant development, India and China have completed the disengagement exercise in the Depsang and Demchok friction points at the Line of Actual Control (LAC) in eastern Ladakh. The troops of both the countries are now verifying the vacation of positions and removal of infrastructure.

Reportedly, the Indian Army said that coordinated patrolling will start soon by both sides, and the ground commanders will continue to hold talks. The two sides will exchange sweets for Diwali tomorrow.

Earlier, Foreign secretary Vikram Misri announced that New Delhi and Beijing reached an agreement to disengage in the remaining friction points at LAC in eastern Ladakh. After the agreement, the two countries began troops disengagement at the two friction points at Demchok and Depsang plains on October 23.

India-China relations worsened because of the Chinese troops’ aggression along the Line of Actual Control, the de facto border, in April 2020. It further deteriorated on June 15, 2020, after 20 Indian soldiers died in the line of duty thwarting the Chinese offensive in the Galwan Valley. New Delhi had said India’s bilateral relations with China will normalise only after the situation at the LAC returns to what it was before May 2020.

Reports said that the Indian Army and the Chinese People’s Liberation Army (PLA) have pulled back their forward-deployed troops and equipment from the two flashpoints, and have also dismantled temporary structures that had been built during the four-year-long standoff.

The Indian soldiers will resume their patrolling in areas that had been cut off because of the PLA’s presence. Nonetheless, the disengagement in Depsang and Demchok will not lead to the creation of buffer zones.

Both the countries had disengaged from Galwan Valley, Pangong Tso, Gogra (PP-17A) and Hot Springs (PP-15) areas and created buffer zones. Speaking to a newspaper publication, Lieutenant General Vinod Bhatia (retd), a former director general of military operations said that the disengagement at Depsang and Demchok will facilitate patrolling by both sides in a coordinated manner, and in the agreed upon frequency and strength of the patrolling parties.
