The Institution That Shaped Modern Indian Science

A journey from Mahendra Lal Sircar's vision to global scientific excellence. The year 2026 marks the sesquicentennial of the Indian Association for the Cultivation of Science (IACS), Kolkata, the oldest institution in India devoted exclusively to fundamental scientific research. Founded on 29 July 1876 by the visionary physician and educationist Dr Mahendra Lal Sircar, IACS emerged when India lacked institutions dedicated to experimental science. Convinced that scientific inquiry was indispensable for national progress, Sircar established an institution to nurture original research by Indians while promoting scientific knowledge among the public. One hundred and fifty years later, IACS remains one of India's foremost research institutions, its history closely intertwined with the evolution of modern science in the country. The genesis of IACS reflected the intellectual ferment of the Bengal Renaissance. Trained in Western medicine yet deeply committed to India's intellectual emancipation, Sircar argued that science should be cultivated through experimentation and discovery rather than merely imported through textbooks. Inspired by institutions such as the Royal Institution of Great Britain, he envisioned a publicly supported national laboratory where Indians could pursue independent scientific research. At a time when such opportunities were scarce under colonial rule, IACS became the country's first permanent home for fundamental scientific investigation. During its early decades, the Association combined public lectures and scientific demonstrations with laboratory research, fostering an interdisciplinary culture spanning physics, chemistry and the natural sciences. Though modest in resources, it established an enduring tradition of curiosity-driven research. The defining chapter in IACS history began with the arrival of Chandrasekhara Venkata Raman in 1907. While serving in the Indian Finance Department, Raman spent his evenings and holidays conducting experiments at IACS on acoustics, optics and the scattering of light. On 28 February 1928, he and his collaborators announced the discovery of the inelastic scattering of light by molecules—the Raman Effect—creating a powerful spectroscopic technique that transformed the study of molecular structure. Today, Raman spectroscopy is indispensable across chemistry, materials science, biology, medicine, pharmaceuticals, environmental monitoring and planetary exploration. For this achievement, Raman received the 1930 Nobel Prize in Physics, becoming the first Asian to win a Nobel Prize in the sciences for work conducted entirely in India. His success demonstrated that world-class scientific research could emerge from Indian laboratories. Yet IACS's scientific legacy extends far beyond Raman. Kedareswar Banerjee advanced crystallographic research through pioneering X-ray crystallography, while Satyendra Nath Bose's association with IACS enriched the intellectual environment that fostered advances in quantum physics. Meghnad Saha's theory of thermal ionisation transformed astrophysics, and together Raman, Bose and Saha established Kolkata as one of Asia's leading scientific centres. The institution also made major contributions to chemistry through Jnan Chandra Ghosh, whose work in physical chemistry laid foundations for modern chemical research in India. Following Independence, IACS expanded into chemical sciences, materials science, biological sciences and theoretical physics, reflecting the increasingly interdisciplinary nature of scientific inquiry. Among its distinguished scientists was Asima Chatterjee, whose pioneering research on natural products chemistry and medicinal plant alkaloids transformed phytochemistry and contributed significantly to pharmaceutical science. Ajoy Ghatak further strengthened IACS's reputation through his work in fibre optics, waveguides and laser physics, while his textbooks educated generations of physicists and engineers. More recently, IACS researchers have advanced ultrafast spectroscopy, nanomaterials, renewable energy, molecular electronics, quantum materials and computational biology. Today, IACS functions as a deemed-to-be university under the Department of Science and Technology, Government of India. Its interdisciplinary research spans the chemical, physical and biological sciences, supported by advanced facilities in spectroscopy, microscopy, X-ray diffraction, electron microscopy, computational modelling and materials characterisation. Its doctoral and postdoctoral programmes continue to produce scientists who contribute to universities, research laboratories and industry worldwide. The institution's enduring strength lies in its commitment to curiosity-driven research. Unlike organisations established primarily for technological development or industrial applications, IACS has consistently recognised that transformative innovation begins with fundamental scientific understanding. This philosophy, articulated by Mahendra Lal Sircar nearly 150 years ago, remains especially relevant in an era defined by quantum technologies, artificial intelligence, sustainable energy and molecular medicine. The sesquicentennial of IACS celebrates not only a remarkable institution but also the evolution of Indian science. From its modest beginnings in colonial Calcutta to its emergence as an internationally respected research institution, IACS has nurtured Nobel laureates, pioneering physicists, eminent chemists and generations of young researchers who continue to expand the frontiers of knowledge. As IACS enters its second century and a half, it carries forward Mahendra Lal Sircar's vision that science should be pursued with intellectual freedom, experimental rigour and an unwavering commitment to the advancement of humanity. Its 150-year legacy remains a powerful reminder that the greatest scientific discoveries begin with curiosity and flourish in institutions dedicated to excellence.

Caste-based Census Sparks Nationwide Debate

Updated: Oct 22, 2024

Caste-based Census

Caste-based identities continue to dominate rural India, directly or indirectly shaping electoral outcomes. Many major elections are influenced by specific caste groups. After the Bihar government released the first phase of its caste-based socio-economic survey, the caste census became a hot topic. The results, backed by evidence, showed improvements in the living standards and social status of marginalised communities, both in cities and villages. With parties like the JDU and NCP backing a caste census, there is growing momentum for the government to conduct one. However, every story has two sides—joy and sorrow. Even Mahatma Gandhi, the Father of the Nation, raised concerns about the caste census.

Rahul Gandhi accused the BJP of being “anti-Bahujan.” The clear meaning is that his father and forefather refused to execute a caste-based census, which might have far-reaching effects and even permanently fracture India’s social fabric. This may be negative for caste-based beneficiaries. The last caste census in India was conducted in 1931 by the British government. Those times were different from the present scenario. The data was made public and became the basis for the Mandal Commission Reports and reservation policies for Other Backward Classes. Rashtriya Swayamsevak Sangh (RSS) has clarified that the caste-based population count data will not be used for core politics. But the agenda for politics is always twisted and expanded.

The Central Government also joined the legal debate by filing an affidavit with the Supreme Court, leaving the matter unresolved. India’s partition, rooted in the divide-and-rule strategy, is frequently cited as a cautionary tale. Including caste in official census data could further deepen social divides. This issue has become a political pressure point, with various states pushing the Centre for action. Although the Constitution uses the term “class” instead of “caste,” the Supreme Court has consistently ruled that caste is a relevant, and at times, sole or dominant criterion for defining a backward class.

After the release of caste-based census data in Bihar, discussions around conducting similar censuses have gained momentum in states like Rajasthan, Chhattisgarh, and Jharkhand. Karnataka, which has already conducted its own caste census, may release its data soon as well.

Notably, all these states are governed by anti-BJP parties. Congress leader Rahul Gandhi also announced that Congress-ruled states have committed to carrying out caste censuses. Meanwhile, the BJP has remained silent on the matter, creating a significant roadblock.

Caste-based censuses focus on proportional representation in areas like jobs and education, with the argument that this will aid in targeted planning for the disadvantaged. However, the situation remains unclear, much like a foggy winter morning. The BJP’s stance on caste-based censuses and reservations seems different, as they fear the caste-based calculations could fragment their traditional Hindu voter base—an underlying concern for the party.

Professor Sanjay Kumar from The Centre for the Study of Developing Societies, says, “Let alone the BJP; no party can openly oppose it; it is not free from danger. BJP gets a large number of votes from the OBC community, their population across the country would be around 52%. Another downside is that the caste-based censuses could disrupt the balance of socio-economic zones. Data theft is a common issue in government systems, and people may feel disconnected from their actual rights.

The moot question is that if the financial status of an ST/SC/OBC or Dalit citizen moves up by a few notches, will his social status change automatically? The lifestyle of any class will only change when the income of a particular class is changed. The actual source of income is employment. The reality is that only metro cities have enough place and space for workers. Aside from the GIDC and IT sectors, less than 30% of industries have their own designated vacancy periods. After a decade, the Jamnagar and Rajkot Corporations have opened their doors to newcomers alongside experienced staff. However, age and caste bias often operate behind the scenes. It’s important to recognise that poverty is also widespread among many upper-caste individuals, and their needs cannot be overlooked. In the overall interests of the nation, terms like SC/ST/OBC, Dalits, etc. must be deleted from the nation’s vocabulary. Every citizen should have only one classification, that of being an ‘Indian’, in the spirit of the constitution.

Last year, when the Bihar government decided to conduct a caste survey in the state, the BJP was also Nitish Kumar’s partner in the state government, and it supported it. Political expert and former professor of Tata Institute of Social Science, Pushpendra Kumar, says, “It is not that the BJP does not talk about caste. It tries to reveal the caste of the Prime Minister as well. For caste politics, the BJP also tried hard to raise the issue of Pasmanda Muslims.”
