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.

Prime Minister Narendra Modi revived his ‘dimagi Naxal’ remark while addressing the centenary celebrations of Shri Ram College of Commerce (SRCC) in Delhi on Saturday, using the term to criticise his opponents.

Speaking to students at the Delhi college, PM Modi described the phrase as a “homeopathic pill” and said it had prompted those he described as “dimagi Naxals” to come forward and reveal their views.

The prime minister also used his address to speak to Gen-Z about India’s development journey and asked students to consider the challenges the country had faced in the past.

PM Modi recalls past crises

During his speech, PM Modi referred to the 2013 Kedarnath disaster and the 2008 global financial crisis while criticising the handling of national emergencies by previous governments.

He said the government at the time of the Kedarnath disaster was shaken and questioned its ability to respond to the crisis.

Referring to the 2008 banking crisis, PM Modi alleged that the government of the time failed to effectively deal with the situation and claimed that India’s banking system was pushed close to collapse.

Prime minister lists challenges faced by his government

PM Modi also highlighted several major global crises that occurred during his government’s tenure.

He mentioned the COVID-19 pandemic, the Russia-Ukraine war, disruptions to global trade and supply chains, and the crisis in West Asia.

The prime minister said there had been concerns that India would struggle during these crises but argued that the country had continued to move forward.

PM Modi’s earlier SRCC visit

PM Modi had earlier visited SRCC in 2013, when he was the chief minister of Gujarat. His speech at the college received significant attention, particularly on social media, ahead of the 2014 Lok Sabha election.

His latest visit came during the college’s centenary celebrations, where his address focused on young people, India’s development ambitions and the challenges faced by the country.

PM Modi returns to SRCC after 13 years, revisits 2013 glass full speech

PM Narendra Modi returned to SRCC after 13 years for its centenary celebrations, revisiting themes from his landmark 2013 address.

Published

PM Narendra Modi

Prime Minister Narendra Modi returned to Delhi University’s Shri Ram College of Commerce (SRCC) on Saturday, 13 years after his previous visit to the institution as Gujarat chief minister. 

His latest visit came as SRCC marked its centenary celebrations. Modi’s 2013 address at the college had attracted significant attention as he spoke about India’s youth, governance and the country’s demographic potential.

In 2013, Modi was Gujarat chief minister and had not yet been named the BJP’s prime ministerial candidate. He returned to the same campus this year as Prime Minister, having completed 12 years as Prime Minister and serving his third consecutive term. 

What PM Modi said at SRCC in 2013

The 2013 lecture was titled Emerging Business Models in the Global Scenario. The address also covered governance and India’s young population.

He described India’s youth as a source of national strength rather than simply a group of new-age voters. He also highlighted India’s demographic advantage and argued that the country needed to make better use of its young population.

One of the notable moments from the speech involved a glass of water.  Modi contrasted the conventional descriptions of a glass as half full or half empty and said he viewed it as full, with half containing water and the other half air.

The speech also included his remarks on technology and young Indians. Referring to an anecdote from a visit to Taiwan, Modi used the phrase “mouse-charmers” to describe Indians using computers and suggested that young Indians had the ability to influence the world through technology.

‘Minimum government, maximum governance’

Modi’s 2013 address also touched on governance. He spoke about the role of government and the need for better governance.

He also spoke about India’s potential in the 21st century. 

Modi returns as PM for SRCC centenary

The September 5 visit coincided with Teachers’ Day and SRCC’s 100th anniversary. The Prime Minister’s Office had announced that Modi would participate in the college’s centenary celebrations and address the gathering. SRCC was established in 1926 by industrialist and philanthropist Sir Shri Ram.

Earlier this year, Modi also met the SRCC governing body at his residence in April in connection with the college’s centenary celebrations and released a commemorative postage stamp marking the occasion. 

The return to SRCC came 13 years after his 2013 appearance at the college, when he addressed students as Gujarat chief minister.
