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.

Aban Ahmed, the youngest son of slain gangster-turned-politician Atiq Ahmed, was killed along with his friend in a road accident in Uttar Pradesh’s Jhansi district on Thursday after the SUV they were travelling in crashed into a divider.

Police said the second victim has been identified as 25-year-old Sonu, son of Raja. Three other occupants of the vehicle sustained injuries and were later shifted to Prayagraj for further treatment at the request of their families.

SUV crashed while travelling to Jhansi

According to police, 20-year-old Aban Ahmed, a resident of Prayagraj, was travelling to Jhansi to meet his two brothers, who are lodged in separate jails in the district. The accident occurred around 10.30 am on the Kanpur-Jhansi Road in the Poonch area.

Superintendent of Police (Rural) Arvind Kumar said the vehicle involved was a Hyundai Creta bearing registration number UP 70 FW 2432.

The injured have been identified as Azam (28), Mohammad Javed (30), and Mohammad Umar (24), all residents of Prayagraj.

Survivor says vehicle was moving at high speed

One of the injured passengers, Mohammad Umar, said the SUV was travelling at a high speed before the driver lost control.

“The car was travelling at a high speed, and the driver lost control,” Umar told reporters while receiving treatment.

Senior Superintendent of Police BBGTS Murthy said the preliminary investigation also indicates that the SUV was speeding. He added that one of the injured passengers informed police that the vehicle became uncontrollable before hitting the road divider.

Police examining CCTV footage

Police have launched an investigation into the accident and are reviewing CCTV footage from cameras installed along the national highway.

Officials are also examining whether the driver lost control after an animal suddenly came in front of the vehicle. However, police said no conclusion has been reached and the investigation is continuing.

Bodies taken to Prayagraj

After a post-mortem examination conducted by a panel of three doctors at Jhansi Medical College, the bodies of Aban Ahmed and Sonu were taken to Prayagraj late Thursday night for the last rites.

Rahul-Gandhi

The Congress on Thursday extended its support to students protesting in Ranchi against alleged irregularities in recruitment examinations, with Leader of Opposition in the Lok Sabha Rahul Gandhi saying that every government should listen to students’ concerns and work towards reforming the education system.

The party, which is part of the Jharkhand Mukti Morcha (JMM)-led government in the state, also said it would continue working to ensure students receive justice.

Rahul Gandhi calls for education reforms

During an interactive ‘Ask Me Anything’ session on Instagram, Rahul Gandhi was asked to support the ongoing student protest in Jharkhand.

Responding to the request, Gandhi said the student movements taking place across the country reflect growing dissatisfaction with the education system. He described the current system as unaffordable and oppressive, adding that meaningful reforms are needed.

He further said that every government—whether at the Centre, in Jharkhand, or a Congress-led state—must listen to students and take steps to improve the education system.

Congress says it stands with students

Congress president Mallikarjun Kharge said the party would support students irrespective of which party is in power. He said Congress leaders would raise the matter with the Jharkhand government and seek answers on the concerns raised by students.

Earlier in the day, AICC Jharkhand in-charge K. Raju and state Congress leaders met Chief Minister Hemant Soren and submitted a memorandum highlighting the students’ demands.

Raju later said the delegation appreciated the chief minister’s decision to constitute a ministerial committee to consult with the protesting students and recommend practical solutions.

He also reiterated that the Jharkhand Congress, along with the Indian Youth Congress (IYC) and the National Students’ Union of India (NSUI), stands firmly with the agitating students.

Protest enters 13th day

The protest over alleged irregularities in Jharkhand Public Service Commission (JPSC) and Jharkhand Staff Selection Commission (JSSC) recruitment examinations entered its 13th day on Thursday.

Six protesters continued their hunger strike, while students and job aspirants formed an 11-member delegation to hold discussions with the government.

The agitation began on July 25 under the banner of the JPSC-JSSC Reforms Manch at Jaipal Singh Munda Stadium in Ranchi and has emerged as one of the state’s largest student-led movements in recent years.

The protesters are demanding cancellation of the 14th Jharkhand Public Service Commission Civil Services Examination and an independent investigation into the alleged irregularities by either the Central Bureau of Investigation (CBI) or a panel of retired high court judges from outside Jharkhand.

Hemant Soren assures action

A day before the proposed talks, Chief Minister Hemant Soren said his government’s doors were open for discussions with the students.

In a post on X, Soren said the concerns raised by the students were being taken seriously and that investigative agencies were working continuously to identify those responsible for the alleged irregularities.

He said the government’s objective was not only to investigate the matter but also to provide a long-term solution to students’ concerns. Soren assured that every demand and suggestion would be carefully examined before announcing concrete measures.

Chhattisgarh High Court denies bail to ex-IAS officer in CGPSC paper leak case

The Chhattisgarh High Court has denied bail to retired IAS officer Jeevan Kishore Dhruv in the alleged CGPSC paper leak case, saying competitive exam paper leaks have a devastating impact on the careers of lakhs of aspirants.

paper Leak

The Chhattisgarh High Court has rejected the bail plea of retired IAS officer Jeevan Kishore Dhruv, who was arrested by the Central Bureau of Investigation (CBI) in connection with the alleged Chhattisgarh Public Service Commission (CGPSC) recruitment scam.

The court observed that leaking question papers of competitive examinations is “more heinous than murder” because it destroys the careers of lakhs of young aspirants and damages the integrity of the public recruitment process.

High Court cites seriousness of allegations

Justice Bibhu Datta Guru, while rejecting Dhruv’s bail application, noted that the alleged offence had a far-reaching impact on society and could not be treated as an ordinary crime.

The court observed that people involved in leaking competitive examination question papers jeopardise the future of candidates who spend years preparing for government recruitment examinations.

According to the order, the prosecution has, at the prima facie stage, collected material indicating that Dhruv, while serving as Secretary of the CGPSC during the 2020-2022 recruitment process, allegedly retained confidential question papers of the 2021 Main Examination and supplied them to his son.

The High Court also noted that the investigation pointed to the applicant’s alleged involvement through witness statements, documentary evidence and recoveries made during searches.

Considering the gravity of the allegations and their impact on the credibility of the recruitment process, the court said it was not inclined to grant bail.

Defence argues false implication

During the hearing, Dhruv’s counsel argued that the retired IAS officer had been falsely implicated only because he served as the CGPSC Secretary and was not named in the original FIR.

The defence submitted that no incriminating electronic devices or documents, apart from a mobile phone, were recovered from him. It also contended there was no evidence proving that he leaked confidential question papers or shared them with his children.

The counsel further argued that after learning both his sons were candidates in the examination, Dhruv informed the competent CGPSC authorities and requested to be relieved of all confidential work related to the recruitment process. According to the defence, official records showed he was subsequently assigned no confidential examination duties.

The defence also maintained that allegations of favouritism were weakened by the fact that one of Dhruv’s sons failed to qualify, while the other secured a rank below the top position.

CBI opposes bail

Opposing the plea, the CBI argued that the case involved large-scale irregularities that undermined public confidence in the recruitment system.

The agency alleged that Dhruv, along with the then CGPSC chairman, controller of examinations and other accused persons, entered into a criminal conspiracy to leak confidential question papers of the 2021 Main Examination, giving his son an unfair advantage.

According to the CBI, copies of questions and answers related to General Studies Paper VII and the Question-cum-Answer Booklet of the Essay paper were recovered during searches conducted at Dhruv’s residence.

The investigating agency also argued that the retired IAS officer could not claim parity with a co-accused who had received bail from the Supreme Court, as Dhruv was a senior public servant responsible for maintaining the secrecy and integrity of the examination process.

Several others also arrested

Apart from Jeevan Kishore Dhruv, those arrested in the alleged recruitment scam include former CGPSC chairman Taman Singh Sonwani, his nephews Nitesh Sonwani and Sahil Sonwani, former Deputy Controller of Examinations Lalit Ganvir, industrialist Shravan Kumar Goyal, his son Shashank Goyal, and daughter-in-law Bhumika Katiyar.
