Remembering CV Raman on his 50th death anniversary: The Eminent Physicist

After India’s independence in 1947, CV Raman became the director of the Raman Research Institute.

CV Raman

Sir Chandrasekhar Venkata Raman popularly knows as CV Raman was one of the most prominent scientists in India. He was awarded the Nobel Prize in Physics in 1930 for discovering the Raman Effect. The Raman effect is the inelastic scattering of a photon by molecules which are excited to higher vibrational or rotational energy levels. It is also called Raman scattering.

The Raman effect forms the basis for Raman spectroscopy which is used by chemists and physicists to gain information about materials. Every year, National Science Day is celebrated to commemorate the discovery of the ‘Raman Effect’ on February 28.

On his 50th death anniversary, let us remember the great mind and his contributions to science and this country:

  • After India’s independence in 1947, CV Raman became the director of the Raman Research Institute. Earlier in 1928, Raman had also led an experiment with KS Krishnan on the scattering of light when he discovered the phenomena of light which is now called the ‘Raman effect’.
  • In 1933, Raman joined the Indian Institute of Science, Bangalore, and became its first director. He also employed a monochromatic light from a mercury arc lamp which penetrated transparent material and was allowed to fall on a spectrograph to record its spectrum. Raman also detected the lines on the spectrum, which were later known as ‘Raman lines’.
  • Other investigations carried out by Raman are either experimental and theoretical studies on the diffraction of light by acoustic and ultrasonic and hypersonic frequencies which were also published from 1934 to 1942, along with the effects produced by X-rays on infrared vibrations in crystals when exposed to ordinary light.
  • Raman was appointed as the first National Professor by the new government of India in 1947. During the post-independence period, Raman studied the spectroscopic behaviour of crystals and approached a unique manner for the fundamental problems of crystal dynamics. After leaving IISc in 1948, he remained the director of Raman Research Institute until he died on November 21, 1970 at the age of 82.

International Day of Persons with Disabilities

International Day of Persons with Disabilities is an international observance promoted by the United Nations since 1992. It is celebrated on December 3 all around the world. It aims to increase public awareness, understanding and acceptance of people with disabilities and celebrate their achievements and contributions.

IDPD mobilizes support for critical issues relating to the inclusion of persons with disabilities, promotes awareness-raising about disability issues and draws attention to the benefits of an inclusive and accessible society for all.

UN agencies, civil society organizations, academic institutions and the private sector are motivated to support IDPD by collaborating with organizations for people with disabilities to arrange events and activities.

International Day of People with Disability: Theme

The theme for IDPwD 2020 is “Building Back Better: toward a disability-inclusive, accessible and sustainable post COVID-19 World”.

Every year the UN announces a theme to observe for International Day of People with Disability. The annual theme provides an overarching focus on how society can strive for inclusivity through the removal of physical, technological and attitudinal barriers for people with disabilities.

This has been occurring since 1992 when the General Assembly announced 3 December as the International Day of Disabled Persons.

National Disability Strategy 2010–2020

In Australia, the National Disability Strategy 2010–2020 commits all governments to a nationwide approach aimed at improving the lives of disabled people, their families and carers.

The Strategy’s ten-year national framework for reform concentrates on better inclusion for people with disabilities and seeks to create a society that enables people with disabilities to fulfill their potential as equal citizens.

On the 2012 International Day of People with Disability, the United Kingdom government introduced mandatory work for disabled people who received welfare benefits in order to “Improve disabled peoples chances of getting work by mandatory employment”.

A program is also launched on December 3 across India to serve the differently-able community of the country as an initiative called Accessible India Campaign under the Article 9 of UN Convention on the Rights of Persons with Disabilities (UNCRPD)

Farmers on Protest

Eager to break the deadlock with famers who are agitating for scrapping the new farm laws, the Bharatiya Janata Party (BJP) leadership held meetings for a second consecutive day on Monday and sent out the message that the Union government is ready for talks.

Union home minister Amit Shah met Union minister for agriculture, NS Tomar earlier in the day to discuss the strategy to break the logjam. A senior party functionary said, “The message from the top is clear that the laws are not anti-farmers and that the farmers are being misled. Prime Minister Narendra Modi has reiterated that laws will offer better opportunity for the farmers.”

The functionary said the government is ready to sit across the table and discuss the new laws and “address whatever concerns” the farmers have.

Speaking in Varanasi, the PM on Monday said the laws have given farmers new options and legal protection. He lashed out at the opposition for “misleading” the farmers and said earlier decisions of government were opposed now rumours have become the basis for opposition and propaganda is being served even though the laws favour the farmers.

The party has also opted for a cautious, measured response to the agitation. Even though it is pinning the blame on the opposition for provoking the protest, it is taking care not to rile the farmers. “The farmers are innocent. They are being misled by those with vested interests. The laws have barely been implemented and their impact is yet to be ascertained, so how can people rush to call these anti-farmers,” said Rajkuamr Chahar, head of the BJP’s Kisan Morcha.

He said the Punjab unit of the Morcha has been communicating with the farmers’ representatives and has relayed the government’s willingness to address their concerns.

On Monday, even as the party tried to diffuse the anger against the bills, its ally the Rashtriya Loktantrik Party (RLP) joined the chorus for the rollback of the laws. Rajasthan lawmaker and RLP chief, Hanuman Beniwal, shot off a letter to Shah, seeking the reversal of the laws.

“….In view of the countrywide sentiment in support of the ongoing farmers’ movement, the recently introduced three bills related to agriculture should be immediately withdrawn. (The Centre must) implement all recommendations of the Swaminathan Commission, and immediately hold dialogue with farmers in Delhi,” he said.

The BJP, however, played down the ally’s demand. Its national spokesperson on economic issues, Gopal Krishna Agarwal said, “We assure all, including our NDA partners that farmers’ well-being and welfare are in our heart. Large scale market reforms are needed and that has always been the consensus.”

He went on to add that while the BJP opposes misgivings about the APMC mandis being dismantled and MSP being withdrawn, the opposition is politicizing the issue along with the Arhtiyas (commission agents) and middleman.

“We have offered all the basic facilities to farmers, drinking water, toilets, shelters and medical facilities. They have been given permission to protest and also been invited for dialogue. We are open for all discussions on the merits or demerits of the three bills. If farmers have certain serious concerns, we are ready to listen to them,” he said.

Lunar Eclipse 2020: The fourth and the last Upachaya Chandra Grahan (Penumbral Lunar Eclipse) of 2020 will take place today. Though Sutak is not applicable during Upachaya Chandra Grahan, the constant movements of the Grahas (planets) may cast an impact on zodiac signs. It may influence people’s natal charts. Hence, people must chant mantras to negate the negative effect of Grahan.

The Lunar Eclipse will have a duration of 4 hours and 18 minutes. It will begin on Monday at 1.04 pm and reach its peak at 3.13 pm. The Lunar Eclipse will end at 5.22 pm and will have a magnitude of 0.82.
