National Science Day 2022: Interesting facts about Nobel Laureate CV Raman and why the day is important

The National Science Day (NSD) is celebrated every year on 28 February to commemorate the renowned Indian physicist CV Raman. He won the Nobel Prize in Physics in 1930 for discovering the Raman Effect, a phenomenon in spectroscopy.

India's most revered scientist Chandrasekhara Venkata Raman aka CV Raman, was born on 7 November, 1888 in Tamil Nadu. His father, who was a lecturer of Mathematics and Physics, had been a big influence on Raman to follow the course of science.

From his early years, CV Raman was fascinated with the scattering of light that later made him discover the change in wavelength that is seen when a beam of light is deflected by molecules. This scattering phenomenon was named as ‘Raman scattering’ or the ‘Raman effect’.

This year, the theme for National Science Day is "Integrated Approach in S&T for a Sustainable Future".

On the occasion of National Science Day 2022, here are some interesting facts about CV Raman:

- At only 11 years of age, Raman passed the matriculation as he was exceptional in his studies. He also passed the Intermediate-level of examination and joined the Presidency College two years later in 1902.

- Raman then went on to get his bachelor’s degree in 1904, where he got himself a first rank and gold medal in Physics. Following bachelor’s, he also completed his masters’ degree.

- Despite bagging a government job in the finance department of the colonial government, Raman quit it. He was then appointed as the first Palit Professor of Physics at the University of Calcutta in 1917.

- During his teaching tenure, he simultaneously conducted research at the Indian Association for the Cultivation of Science (IACS). In 1928, while carrying out experiments on scattering of light, he proudly ended up discovering the 'Raman Effect'.

- A year later, Raman won the Knight Bachelor award and became a Fellow of the Royal Society. In 1933, he was appointed as the first Indian director of Indian Institute of Science (IIS) for his hard work and contributions.

- When India gained independence in 1947, Raman was selected as the first National Professor of the country. He was also conferred with the highest civilian award of India, Bharat Ratna in 1954. Raman passed away in 1970.

- Years later, the country celebrated the first National Science Day on 28 February, 1987.

Elon Musk’s bid spotlights Twitter’s unique role in public discourse – and what changes might be in store

Twitter has been in the news a lot lately, albeit for the wrong reasons. Its stock growth has languished and the platform itself has largely remained the same since its founding in 2006. On April 14, 2022, Elon Musk, the world’s richest person, made an offer to buy Twitter and take the public company private. In a filing with the Securities and Exchange Commission , Musk stated, “I invested in Twitter as I believe in its potential to be the platform for free speech around the globe, and I believe free speech is a societal imperative for a functioning democracy.” As a researcher of social media platforms , I find that Musk’s potential ownership of Twitter and his stated reasons for buying the company raise important issues. Those issues stem from the nature of the social media platform and what sets it apart from others. What makes Twitter unique Twitter occupies a unique niche. Its short chunks of text and threading foster real-time conversations among thousands of people, which

To reach net-zero emissions and remove CO2 from the air, scientists drawn up six priorities

Image
To reach net-zero emissions by 2050, global emissions must be cut faster and deeper than the world has yet managed. But even then, some hard-to-treat sources of pollution – in aviation, agriculture and cement making – may linger for longer than we would like. It will take time for clean alternatives to arrive and replace them. That means the world also needs to find and ramp up ways of taking CO₂ out of the atmosphere to stabilise the climate. Just meeting the UK’s net-zero target is likely to require the removal of 100 million tonnes of CO₂ a year , similar in size to current emissions from the country’s largest-emitting sector, road transport, but in reverse. The UK government’s announcement of £31.5 million (US$44.7 million) in support for research and development of carbon removal is welcome. And while trials of new tech will help, there are many social issues that need to be tackled if removing greenhouse gases is to succeed. Done right, carbon removal could be the perfect a

NASA is planning to partner with SpaceX to reboost the Hubble Telescope and extend its life

Image
The Hubble Space Telescope is one of the most important scientific achievements of the human species that has helped us understand space. It has been in orbit for over 30 years and has been feeding some of the most vital streams of information that has not only helped us steer our space exploration efforts, but also solve some of the more deep mysteries of the universe . NASA would love to extend its usable life for as long as possible. Unfortunately, for some years now, Hubble Space Telescope has been slipping out of its orbit. That is why, NASA is planning to team up with Elon Musk’s SpaceX and place it into a higher much more stable orbit. NASA, SpaceX and Jared Isaacman, a private astronaut with the Polaris Program, hosted a media teleconference on Thursday to announce a feasibility study that will look into sending a commercial Dragon spacecraft to reboost the Hubble Space Telescope . This will, in effect place the telescope into a higher and more stable orbit than it’s curren
