The Raman effect is the reason why India celebrates Science Day
India celebrates National Science Day on February 28th each year to commemorate the discovery of the Raman Effect by the great physicist Sir Chandrasekhara Venkata Raman, also known as CV Raman
Chandrasekhara Venkataraman, popularly known as CV Raman, has a unique place in the history of India’s scientific revolution. He is the first Indian to win a Nobel in science, and the fact that it was in physics added to its significance. He was awarded the Nobel Prize for his work on the scattering of light and for the discovery of the effect named after him, the Raman effect. The scientific importance of his discovery is illustrated by the fact that even today, the majority of research papers in physics are on topics related to the Raman effect. CV Raman also received the Bharat Ratna, India’s highest civilian award, in 1954.
Raman was only 36 years old when he was elected a Fellow of the Royal Society of England in 1924. In 1925, Raman participated in the centenary celebrations of the Russian Academy of Sciences and was awarded the Lenin Peace Award, Russia’s highest award. Raman’s life paints a picture of how science and scientific research should be viewed when superstition and unscientific ideals are spreading across India at a maddening pace.
C.V. Raman was born on November 7, 1888 as the second of eight children of Chandrasekhara Iyer and Parvathi Ammal in the Thanjavur district of Tamil Nadu. In 1903, Raman joined Presidency College, Madras, for a BA and was the youngest student to graduate. In 1907, Raman completed his master’s degree with first rank.
Raman started his career in June 1907 as an accountant general in Calcutta. The Indian Association for the Cultivation of Science was located near Raman’s rented house in Calcutta. Raman was allowed to conduct research in his laboratory after working hours. Raman engaged in his research activities early in the morning and at night.
The Raman effect, discovered in 1928, was a continuation of the study of light begun by Raman in 1921, when he observed the blue colour of the sea while sailing from Europe.
Accepting the invitation of Calcutta University Vice-Chancellor Sir Ashutosh Mukherjee, Raman resigned from government service in 1917 and took charge of the Department of Physics at the Calcutta University Science College. The salary received from the university was only half of what was received for his government job.
The Raman effect, discovered in 1928, was a continuation of the study of light begun by Raman in 1921, when he observed the blue colour of the sea while sailing from Europe.
If light shines on a surface, the photons – or particles of light – can scatter inelastically thus gaining or losing energy. If this scattered light is then passed through a prism, the light is further split into its constituent wavelength, generating a colour spectrum. These new lines are called Raman lines, and this spectrum is called the Raman spectrum. This phenomenon related to the scattering of light in liquids is called the Raman Effect or Raman Scattering. It was explained that the colour of the sea is a result of the Raman scattering of light rays by liquid molecules. February 28, when Raman submitted his research paper, is celebrated as National Science Day in India.
Raman expected the Nobel Prize in 1928 when he presented his research paper. But the 1928 Nobel Prize in Physics was won by Owen Richardson, and the 1929 prize was won by Louis de Broglie
Raman expected the Nobel Prize in 1928 when he presented his research paper. But the 1928 Nobel Prize in Physics was won by Owen Richardson, and the 1929 prize was won by Louis de Broglie. This made him very disappointed. But Raman, who was certain that he would get the award in 1930, went to collect the Prize in July of that year.
CV Raman’s scientific career is not limited to Raman effect. His discovery of the quantum photon spin in 1932 underscored the quantum nature of light. Research related to sound waves was also Raman’s favourite subject. He researched musical instruments that produce sound through vibrations. Raman and his disciple Narendranath gave a theoretical explanation of the scattering of light in sound waves (the acousto-optic effect). This is known as Raman-Nath theory. Raman was also involved in research related to lasers. His other research topic was the interaction of sound waves at ultrasonic and hypersonic frequencies with X-rays and their effects on crystals.

Rebranding Bhutan: A case study in transforming identity
Nestled in the lap of the Himalayas lies the breathtakingly beautiful country of Bhutan. It is a serene land, rich in natural beauty. However, as a developing nation, Bhutan had limited basic facilities for tourism. Unlike its neighbouring countries, Bhutan had not experienced significant development or economic growth for a long period.
Moving forward in such a state seemed impossible. Bhutan needed a transformation. The country required a new identity. The Bhutanese government formulated a novel strategy: the “Made in Bhutan” initiative, aimed at promoting the nation’s products and services, alongside a unique philosophy—the “National Happiness Index.”
The goal was to harness Bhutan’s indigenous spiritual values and traditions to drive progress, while creating a new image for the country. And indeed, it worked like a charm. The entire nation united in this effort, with every action reflecting this philosophy. Years later, Bhutan became known as the “Country of Happiness” and transformed into a paradise for tourists.
Bhutan implemented a strategy of rebranding. It dismantled the outdated perceptions of the past and established a new, modern identity in their place. Beyond redefining names, logos, and colors, rebranding in Bhutan involved cultivating a new culture, deeply rooted in the country’s fundamental, traditional values.
Re-branding executed hastily or without proper preparation can lead to failure
We see similar rebranding strategies successfully applied in many businesses. There are various methods for rebranding, and you may have noticed changes in logos, such as with V-Guard. Such changes are often driven by clear necessities and philosophies. Altering deeply entrenched images, symbols, and colors in consumers’ minds is a delicate task that must be executed with care. The rebranding strategy should only be applied when absolutely necessary.
Re-branding executed hastily or without proper preparation can lead to failure. Take the failed re-branding of Tropicana as an example. The company made substantial changes to its old packaging design, creating a completely modern look. However, Tropicana’s new look did not gain acceptance among consumers, leading to a 20% decline in sales. Tropicana quickly reverted to its old design. This failed re-branding process demonstrates the risks of altering deeply ingrained images in consumers’ minds without understanding them.
Re-branding can help create a new identity for a brand, instill novelty, and enhance prestige. However, it should not be viewed as a simple process. In-depth study, research, and preparation are necessary before undertaking a re-branding effort. A brand is the personality of a business, and it requires careful consideration before making any alterations.

Trump’s push to abolish the Education Department: Could it really transform schools?
So, what would an America without the Department of Education look like?
President-elect Donald Trump wants the Department of Education gone. During his presidential campaign, Trump made waves by repeatedly pledging to eliminate the U.S. Department of Education, calling it a symbol of federal overreach and an unnecessary drain on taxpayer money. The promise was bold: “We will ultimately eliminate the federal Department of Education,” he declared at a rally in Wisconsin back in 2016. His critics and supporters alike raised eyebrows, but what would actually happen if such a move were to be made?
The Department of Education, created in 1979 under President Jimmy Carter, has long played a pivotal role in shaping America’s education system. If Trump’s plan were to move forward, it could mean sweeping changes to how K-12 schools are funded and how federal education policies are implemented.
The Core Functions of the Department
The Department of Education performs several essential roles in the American education system. For one, it funnels billions of federal dollars to states and schools. Its two major funding programs—Title I and IDEA—help support schools serving low-income students and children with disabilities. These programs provide nearly $28 billion annually to K-12 schools, although they represent only a small fraction of overall school funding. The bulk of K-12 school budgets comes from state and local taxes. The Department of Education also manages federal student loans and financial aid programs, including Pell grants, which distribute about $30 billion annually to help low-income college students.
Without these programs, how would schools and students fare? The answer isn’t clear-cut, but one thing is certain: federal funding has become a significant tool in ensuring access to education, especially for marginalized groups.
The Bureaucratic Web: Oversight and Regulations
In addition to distributing funding, the Department of Education plays an oversight role, ensuring that schools meet federal standards and investigating issues of discrimination. Through its Office of Civil Rights, the department enforces rules aimed at preventing discrimination on the basis of race, gender, and disability in schools. Over the years, the department has also been a key player in regulating hot-button issues—such as protections for transgender students and regulations on student loan forgiveness programs.
But what happens if this regulatory body no longer exists? One potential scenario could involve the transfer of these responsibilities to other federal agencies or a decentralization of decision-making power to state and local governments.
Federal Funds: The Strings Attached
Federal money doesn’t come without conditions. For instance, schools that receive funding through programs like Title I must adhere to certain rules and regulations. These guidelines can sometimes create what many consider “red tape.” For years, critics of the Department have argued that the bureaucracy tied to federal funding slows down school improvement efforts and imposes undue burdens on local administrators.
According to experts, the funding programs might survive, albeit in a different structure
Some policy experts suggest that even if the Department of Education were dissolved, the funding itself could continue—possibly in the form of block grants that offer more flexibility to local districts. But others warn that dismantling the department could result in a loss of essential oversight and services, especially for students with special needs.
What Happens to Federal Education Programs?
Interestingly, many of the funding programs the Department of Education oversees—particularly Title I and IDEA—were in place before the agency itself existed. This raises the question: Would these programs disappear if the department were abolished?
According to experts, the funding programs might survive, albeit in a different structure. Congress, which ultimately controls federal spending, has historically resisted efforts to cut education funding, even during budget negotiations when past presidents proposed cuts. Many believe that, even if the Department were to close its doors, the political and public support for these funding streams would likely push them into different agencies or programs.
Can Congress Actually Abolish the Department of Education?
While Trump’s rhetoric may have made abolition sound simple, shutting down a federal agency is no small feat. It would require an act of Congress—a challenge that previous efforts have failed to overcome. Even President Ronald Reagan, shortly after the department’s creation in 1980, proposed its elimination but eventually backed down due to lack of congressional support. The Trump administration also tried to merge the Education and Labor Departments, but that effort stalled in Congress.
Even if the GOP gains unified control of Washington in the coming years, it remains uncertain whether there will be enough support to completely dismantle the Department of Education.
The Road Ahead
So, what would an America without the Department of Education look like? In reality, it’s likely that some form of federal oversight and funding would continue, but the shape of it could change significantly. If Congress and the president were to act, the most likely outcome would be a shift in how federal funds are distributed—potentially with fewer strings attached—and a reorganization of some of the department’s key functions.
While Trump’s rhetoric may have made abolition sound simple, shutting down a federal agency is no small feat. It would require an act of Congress
Ultimately, the debate about whether to abolish the Department of Education touches on much larger issues: how to balance federal power with state autonomy, how to fund public schools fairly, and how to ensure that all students, regardless of background, have access to a high-quality education.
As the conversation continues, one thing is clear: any significant change to the Department of Education would have profound implications for the future of education in America, particularly for its most vulnerable students. Whether that future is shaped by a more decentralised approach or by a reformed federal agency remains to be seen. But one thing is for sure—the stakes are high.

India: Big Science in the 20th century and beyond
In this blog post, Ed Publica’s Science Editor, Karthik Vinod, skims over some of the state-funded science projects in India that existed before and after independence.
Science after World War II
Scientific research changed forever in the aftermath of the World War II. Nuclear weapons entered the fray, and scientists worked – not alone anymore – but now in groups rivalling organizations. Governments walked in for the first time, institutionalizing science as a state-project. In the US, Vannevar Bush’s Science: the Endless Frontier advocated for a dichotomy within science, between applied and basic research. India soon advocated for something Though flawed, it’s a blueprint used across the world, including in India. But it needs to change.
Following independence, Jawaharlal Nehru, India’s first prime minister, resorted to building centralized institutions across the country, with the Indian Institute of Technologies (IITs) being famous amongst those pursuing a technical stream. Along with the Indian Institute of Science (IISc.), they’ve attracted the country’s most meritorious and bright students. Nehru viewed and appreciated scientific thinking as a “way of life” and an aspect that’ll break the shackles of superstitious belief in many Indians. He popularized the phrase “scientific temper”, which was later amended into the Indian constitution by his daughter and late prime minister, Indira Gandhi. However, this was during the Emergency Period, when democracy was curtailed, dissidents were imprisoned, and mass sterilization campaigns castrated many men against their will.
Keeping political hypocrisy aside, the administrations since then hasn’t picked up much steam either on being serious about its fundamental scientific research. This is not to say there hasn’t been marvels in technological innovation. Vikram Sarabhai, the technocrat scientist and aristocrat, who helped seed incentives for the country to invest in a space program, envisioned science and technology to enable Indians use of state-of-the-art technology, without going through the rudimentary “stages of growth” that was thought to plague many developing nations. The Indian Space Research Organization (ISRO) builds satellites and rockets, and has been the harbinger rather in public eye for the country’s assertive rise as a space power. Fundamental science research has taken a backseat, with funding woes and political apathy felt even today.
Funding for ISRO virtually trumps anything else that churns in public scientific institutions. Though this is a common attributed share among space faring nations, India’s amongst the lower tier of nations that spends on research and development (R&D) – constituting just 0.64% of the Indian economy, and a continuing decline in funds allocated in yesteryears. India’s next door neighbor China spends some 2.4%, and both the US and UK spend either 3% or more per year.
It’s not like India doesn’t have illustrious or even seminal scientific contributions in the modern age. Scientific research did flourish in British India, amongst a few practitioners, benefitting from uninterrupted time in their laboratories with relatively cheap equipment– as with experimentalists such as Jagdish Chandra Bose and C.V. Raman; to name a few, or theorists including Meghnad Saha and S.N. Bose. Today though, these names remain largely confined to history in public discourse.
Science in pre-independent India
The imperial capital of science in India, Calcutta, was home to top-tier frontier research in quantum mechanics in the early 20th century. In the 1920s, Satyendra Nath Bose, a theorist, solved a particular problem related to the blackbody radiation law that evaded even Einstein. Bose, whom we profiled in our Know the Scientist page, fostered a collaboration with Einstein, culminating in numerous theoretical advances in quantum statistics, especially predicting the fifth state of matter, the Bose-Einstein condensate. Paul Dirac, the English physicist, coined the name bosons, after the class of quantum particles with integer spins, that Bose and Einstein’s statistics describe properties. It was one of these bosons (a word-play on “Bose-ons”) that particle physicists confirmed at the Large Hadron Collider (LHC) in Geneva, Switzerland in 2012.
Science during British India was top-notch, and continued its trend in the immediate aftermath of Indian independence. In 1948, Calcutta was abuzz again, but now with a cyclotron that they were building. A cyclotron’s a device that accelerates particles to near light-speed in the presence of electromagnetic fields, thereby producing radiation. It aided in frontier research in nuclear physics, for example, measuring cross-sections of the uranium nucleus (U-235). Housed at the Saha Institute of Nuclear Physics, accelerator physicists received funding to build a bigger cyclotron at the Variable Energy Cyclotron Centre, touching energies in the MeV range. Today, it’s part of the International Radioactive Ion Beam consortium, helping spread India’s fundamental research reach across the world.
So far, there’s been little coverage about the research in much of central universities and research institutions. It’s surprising how Bose’s contribution to quantum theory found no mention in India’s media discourse. Indian science hasn’t had limelight, not because there’s little research output – though there’s a case to make, as many has made before – but there’s a need for science communicators and journalists to help bridge that gap that exists between scientists and the public. The government has shown little consideration to extend science communication beyond publishing white papers about its importance.
Scientist or engineer?
Media representation of science is confused. The space program, that receives much public adulation and emblematic of national pride, is wrongly perceived as a scientific institution. Space engineers have become scientists in the public eye, despite rocket and satellite development is a matter of engineering, and not science. The former Indian president and “ISRO scientist” Abdul Kalam wasn’t a scientist per se, but an aerospace engineer. Barely mentioned in our public discourse are scientists that’ve done commendable research across the sciences.
Science done in central or local institutions for that matter hasn’t shared the limelight, anywhere as ISRO has since Independence. It’s the government’s pet, and has shaped narratives of technological innovation within and outside India. But this is largely technology history, without much scientific imperative.
Taking initiative
On the flip side, there’s much smaller science projects, that does combine the best of both worlds, combining technology development and science; thus blurring the dichotomy between applied and basic science research.
Govind Swarup, an Indian astronomer, worshiped by his peers as a “father of Indian radio astronomy” had voiced for a radio observatory, the first of its kind in Asia, to be constructed in the 1950s. The Indian government wasn’t interested, unless the astronomers received funds from sponsor countries. Australia had offered to pay and construct, after a long tussle, following which either party withdrew from discussions.
It was not until the 1980s, did India commence building an indigenous radio telescope. In 1995, the country’s first radio telescope, the Great Metrewave Radio Telescope (GMRT) was operational after a decade of construction. The team at GMRT contributed to the first detections of the cosmic gravitational wave background with its European radio astronomy counterparts in the Pulsar Timing Array project.
In 2016, the Indian astronomy community were greenlit to construct a gravitational wave detector in Pune, following confirmation of gravitational waves in February that year. Though this project too bas been plagued by successive delay construction would supposedly take off soon (perhaps late this year). In light of these late developments, politicians and scientists have begun beating the drums about the potential economic impact from involving Indian industry in the construction of the detector – utilizing state-of-the-art quantum technologies – in partnership with international teams. For the scientific community, precious data from the detector is incentive for attracting and inspiring the country’s emerging scientific talent.
Meanwhile, there’ve been hurdles that’ve prevented few other projects from taking off. The India-based Neutrino Observatory (INO), in Tamil Nadu, is one glaring example. Poor policy making amid environmental concerns that wasn’t addressed in time has forestalled construction for more than a decade. In this case rather, neither scientist nor policy maker bothered to engage with the public and hear out their concerns. And it takes much more development in science policies and public engagement to resolve these systemic issues.
