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.

Border Security Force (BSF) personnel shot and killed an individual attempting to cross the India-Pakistan border in the Ganganagar district of Rajasthan late on Tuesday, according to police.

Jitendra Kumar, the station house officer at Kesrisinghpur police station, stated that the man was trying to breach the barbed wire fence when he was spotted by BSF personnel. “They advised him to leave the area, but when he continued to advance, the BSF personnel shot him,” said the SHO.

Sriganganagar Superintendent of Police Gaurav Yadav confirmed that the suspect was allegedly trying to enter Indian territory around midnight on December 24, 2024. Despite warnings from the BSF soldiers, he did not heed their calls, which resulted in the shooting.

The incident occurred near a village in the Kesarisinghpur area. Items recovered from the intruder included Pakistani currency notes, a cigarette packet, an identity card, and other belongings. Authorities are currently gathering more information about him.

Ongoing discussions are taking place between the armed forces and police officers regarding the incident. An FIR has been filed that includes charges of trespassing and violations of the Passports Act and the Foreigners Act, according to Kumar. “We are investigating the case under these acts,” he added.

This incident is one of several similar occurrences along the border. In August, the BSF apprehended an intruder named Jagsi Kohli, who had entered about 15 kilometers into Indian territory in Barmer after locals alerted authorities that he was asking for directions to Tharparkar, a district in Pakistan’s Sindh province.

In March of this year, another person attempting to cross the border in Ganganagar was shot by BSF personnel. There have been additional incidents reported in October 2022 and twice in March 2021, all resulting in fatalities among the intruders.

Union Home Minister Amit Shah, BJP chief J.P. Nadda and Telugu Desam Party (TDP) president and Andhra Pradesh Chief Minister Chandrababu Naidu among leaders of the NDA met in New Delhi on Wednesday to discuss different issues including Shah’s comment on BR Ambedkar days ago in Rajya Sabha.

In attendance, apart from Shah, Nadda and Naidu, JD-U leader and Union minister Rajiv Ranjan Singh, Apna Dal (S) president and Union minister Anupriya Patel, as well as JD (S) leader and Union minister H.D. Kumaraswamy were present.

Also present were Jitan Ram Manjhi, leader of Bihar’s Hindustani Awam Morcha (S) and a minister in the Modi government, Rashtriya Lok Morcha (RLM) president Upendra Kushwaha, a Rajya Sabha MP, and Thushar Vellappally, president of Bharath Dharma Jana Sena.

While the specific agenda of the meeting was not officially disclosed, sources indicated that discussions revolved around good governance and various political issues—principles that were central to Vajpayee’s tenure as Prime Minister. The alliance had decided to convene on the birthday of the late BJP leader, noted for successfully leading the first coalition government to complete its term.

Following the meeting, Nadda shared on X, “Attended the NDA leaders’ meeting in New Delhi today. Under the visionary leadership of PM Narendra Modi, India is achieving unprecedented milestones and has positioned itself as a global superpower. The NDA government remains committed to realizing the vision of ‘Viksit Bharat@2047’, ensuring a brighter and more prosperous future for all.”

Sanjay Nishad, chief of the NISHAD Party in Uttar Pradesh, described the meeting as “informal” and focused on Vajpayee’s legacy. He emphasised the importance of unity among all alliance members heading into future elections, mentioning that they congratulated the BJP leaders for their electoral victories in Haryana and Maharashtra.

Nishad further outlined that the meeting addressed coalition strategies to ensure that Prime Minister Modi’s initiatives effectively reach the populace and that electoral promises are fulfilled. He raised the topic of providing reservations for the fishing community, stating, “I presented evidence on this issue, as it was a poll promise. They will follow up with us next week to discuss it.”

Responding to inquiries about whether Amit Shah’s controversial remarks on Ambedkar were discussed, Nishad said, “We are here for the welfare of the people. Our energy should focus on achieving success in that area, rather than engaging with negativity from opposition parties.”

The NDA meeting underscores the alliance’s commitment to the proposed simultaneous elections, with all members backing the initiative. A Joint Committee of Parliament, established to review two bills related to simultaneous polls, is set to convene on January 8.

Manipur CM Biren Singh says state needs immediate peace, understanding between two communities

He claimed that the administration is responding quickly to the displaced people’s needs in areas such as education and agriculture.

Published

Manipur Chief Minister N Biren Singh on Wednesday emphasised the urgent need for peace in the state, which has faced ethnic violence since May of last year, and called on two communities to reach a mutual understanding.

Speaking at the Good Governance Day event held at the state BJP headquarters, Singh expressed confidence that the BJP could restore stability to the northeastern state, highlighting the party’s commitment to coexisting harmoniously.

“What is happening in Manipur today has multiple causes. Those who seek to divide the state are now questioning the government’s actions… they are driven by a desire for power,” Singh remarked.

He mentioned several initiatives, such as ‘Meeyamgi Numit’ (People’s Day), designed to foster closer relationships between officials and the public. “We do not oppose any specific community. The BJP’s position is clear: we advocate for the idea of living together and have initiated efforts to strengthen ties between the police and the community,” he stated.

Singh added that the state government is diligently addressing the needs of internally displaced persons by establishing committees throughout the administrative framework. He claimed that the administration is responding quickly to the displaced people’s needs in areas such as education and agriculture.

“We have not made any mistakes. Our goal is to ensure the well-being of future generations. It is essential for both communities to remain calm. Rather than dwelling on the past, we should concentrate on the upcoming NRC process, capturing biometrics, and using 1961 as the foundation year for the Inner Line Permit,” Singh said.

He also highlighted the government’s commitment to acting within a democratic and constitutional framework, noting that achieving these goals will take time. “What we require now is immediate peace and a resolution of misunderstandings between the two communities,” he concluded.

The ongoing violence has resulted in the deaths of over 250 individuals and left thousands homeless due to clashes between the Meitei community and Kuki-Zo groups since last May.

“Only the BJP can save Manipur. BJP leaders possess strong values of nationalism and social justice, practicing reality-based politics in the nation’s interest. If I am not nominated for a ticket by the BJP, I will remain loyal to the party,” Mr. Singh added.

He also highlighted several unity-focused projects initiated by the BJP government, mentioning that a Unity Mall featuring stalls from all ethnic groups in the state will be constructed with an investment exceeding ₹140 crores.
