Today, India maintains its own identity on the global stage in science, which is fulfilling every need from the health sector to defence and the common man. On the occasion of National Science Day on February 28, it is necessary to talk about the pharmacy of the world. Let us tell you that on this day in 1928, Sir Chandrasekhar Venkat Raman discovered the Raman effect. Sir CV Raman was awarded the Nobel Prize in 1930 for this discovery.
How was National Science Day announced
Sir CV Raman was the Tamil Brahman, who served from 1907 to 1933 at the Indian Association for Cultivation of Science, Kolkata. He researched many science subjects. One of them is the Raman effect.
In 1986, the National Council for Science and Technology requested the Government of India that National Science Day should be observed on February 28. The government accepted this request and in 1986, the Government of India declared National Science Day. The first National Science Day in the country was celebrated on February 28 1987.
How National Science Day is celebrated
Every year on February 28, the National Science Day celebrations are held at Vigyan Bhawan in Delhi, with the President being the chief guest. On this occasion, awards are given to those who play a leading role in science.
Sir CV Raman received the following awards
Areas of science in which India recently achieved success
On August 23, 2023, India made history with the successful completion of the Indian Space Research Organisation (ISRO)’s Chandrayaan 3 mission. This significant achievement came nearly four years after the Chandrayaan-2 mission faced challenges in achieving a soft landing on the Moon in September 2019. The success of Chandrayaan-3 marked India as the first nation to explore the lunar south pole, an area previously unexplored.
India Semiconductor Mission (ISM) aims to Propel Electronics Manufacturing
The India Semiconductor Mission (ISM), operating under the Digital India Corporation, is dedicated to fostering a thriving semiconductor and display ecosystem. Its primary objective is to position India as a global leader in electronics manufacturing and design. In 2023, ISM took significant steps toward achieving this goal, including the commencement of construction on Micron’s $2.75 billion semiconductor plant in Sanand, Gujarat. This initiative aims to create a robust semiconductor and display ecosystem, paving the way for India’s emergence as a major hub for chip manufacturing.
INS Vikrant: India’s Indigenous Aircraft Carrier Elevates Naval Capabilities
India’s naval capabilities soared to new heights with the commissioning of INS Vikrant, the nation’s first domestically built aircraft carrier. Weighing 45,000 tonnes and constructed by Cochin Shipyard Limited, INS Vikrant represents a significant stride in India’s pursuit of Aatmanirbhar Bharat (self-reliant India). Named in honor of its predecessor, INS Vikrant embodies India’s commitment to bolstering its defence capabilities and strengthening its maritime presence.
In 2023, India showcased remarkable progress across various technological domains, demonstrating a steadfast commitment to innovation and self-reliance. From advancements in semiconductor manufacturing to space exploration, defence capabilities, and rapid strides in telecommunications, India’s technological achievements underscore its position as a frontrunner in the global technological landscape.
It is said that necessity is the mother of invention, something similar happened with India in the Corona era when PM Modi gave the slogan of self-reliant India, then such talents came out from every corner of the country, who fought the war against this epidemic. Create a weapon by increasing your level by one. The biggest weapon among them was the COVID vaccine. Today, India’s vaccine demand is coming from almost every corner of the world. But all this was possible with science and technology.
In this regard, the Department of Science and Technology says that the Victory campaign to combat Covid-19, started with innovations and startups that have demonstrated a range of technologies, diagnostics and drugs, disinfectants and solutions that address COVUD 19 challenges Sanitiser, ventilator and medical devices, led PPE and incorporated science into the solution to control and treat epidemics, to control the pandemic. All this has been possible in these few months due to the extraordinary sharing of purpose, synergy, collaboration and synergies of research and development institutes, education and industry.
The National Super Computing Mission (NSM) rapidly promoted high-performance computing (HPC) to meet the growing demands of education, researchers, MSMEs and startups in oil exploration, flood forecasting, genomics and drug discovery.
If we talk about the field of space, then India’s largest space science institute, i.e. Indian Space Science Organisation, has completed 109 spacecraft missions to date. Has launched 77 missions, 10 students have launched satellites. Not only this, 319 foreign satellites have been launched for 33 countries.
Simultaneously, DRDO, i.e. Defence Research and Development Organisation established in 1958, gave missiles like Agni, Prithvi, fighter aircraft like Tejas, multi-barrel rocket launcher Pinaka, and many defence equipments including air defence systems like Akash. Moreover, INS Kavaratti, built by Garden Reach Shipbuilders and Engineers (GRSE), is the first 90 per cent indigenous warship. Earlier, the steel used in all warships made from abroad came from abroad; the steel used in this warship was provided by the Steel Authority of India Ltd. of India.
These are not just examples, but these instruments are a witness to the fact that India has proved its science capability in the whole world.
The theme for National Science Day, 2024 is ‘Indigenous Technologies for Viksit Bharat’.
Today, we also remember India’s great scientists, who gave up their whole life for science and technology, which played an important role in the welfare of mankind. Name of some great scientists of India-
Things related to National Science Day one must know
Today, India maintains its own identity on the global stage in the field of science, which is fulfilling every need from the health sector to defence and the common man. On the occasion of National Science Day on February 28, it is necessary to talk about the pharmacy of the world. Let us tell you that on this day in 1928, Sir Chandrasekhar Venkat Raman discovered the Raman effect. Sir CV Raman was awarded the Nobel Prize in 1930 for this discovery.
According to the Raman effect, when a monochromatic light passes through liquids and solids, some other characters of very low intensity are seen along with the incident light in it. Initially, Raman passed through the purple light beam Poonj, obtained by passing the sunlight through a violet filter. The output beam was mainly purple in color, but after passing through the green filter, the presence of green rays in it was also seen in very small quantities.
Understand in colloquial terms, when a ray of light passes through a transparent medium, some part of the light’s ray is dispersed. The wavelength of these dispersed rays is different from the wavelength of the original ray.
