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.

Teaching the Swipe Generation

As Gen Z reshapes university life, educators must balance technology, discipline and empathy in a rapidly changing classroom.

The transformation of higher education has been a stealth change. In today’s classrooms, textbooks, lectures, and exams are no longer the only characteristics of a classroom. Instead, they are influenced by smartphones, artificial intelligence, social media, digital learning platforms and the attitudes of students. The core of this change lies with Generation Z, the generation that has grown up in a hyper connected world, with new expectations, behaviours and challenges for both education and teachers.


Gen Z students are different to their predecessors; they’ve been born to instant access to information. Now, knowledge is not just confined to classrooms or libraries; it is just a click away with search engines, online courses and AI enabled tools. Research reveals that Gen Z spends six-seven hours on digital platforms outside of their academic lessons, which has a significant impact on the way they communicate, learn and take in information. It doesn’t matter if there’s another classroom out there; it’s all about algorithms, notifications, and short attention spans.


Shifting Roles

With this technology, the role of teachers has been shifted from being the only source of knowledge to facilitators, guides and mentors. With this change came opportunities for interactive learning and innovation, as well as new challenges. Teachers see students today are more reliant on digital tools, less willing to wait long periods for a teacher to teach and more likely to get information in short bites, such as through short-form content or social media.


This change was further driven by the COVID-19 pandemic. Online classes became commonplace, digital interaction normal and flexible learning settings normal. Technology helped to maintain continuity in education but it also had a negative impact on face-to-face interaction in classrooms. In today’s world where students are constantly surrounded by distractions of digital technology, many teachers are finding it difficult to keep students engaged and interacting in the classroom.


This “new normal” has been enhanced by artificial intelligence. Students are turning to AI tools, such as ChatGPT and educational platforms, for assignments, research, and exam preparation. The adoption of AI among university students is also on the rise, according to reports by McKinsey & Company, highlighting the speed at which technology is becoming an integral part of university life all over the world. AI has the potential to enhance accessibility and efficiency, but it also poses a threat to critical thinking, originality and excessive reliance on technology.


Respect and classroom behaviour is also a current topic of discussion. Traditional education systems were often authoritarian based with the teacher having unwavering respect. However, Gen Z is more open to straightforward leadership, dialogue and emotions, than hierarchy. This change does not necessarily mean disrespect, rather a generational change in any student’s relationship with relationships and authority in learning spaces.


Socio-Emotional Aspect

As a result, mentorship is emerging as one of the most important aspects of modern higher education. Students want educators who will offer them more than just academic support — support for mental health challenges, career confusion, online distractions, and social anxiety. The World Health Organization (WHO) reported that the anxiety, stress, and burnout of young people have increased dramatically in recent years, especially since the pandemic. Schools are thus forced to address the socio-emotional aspect of learning and the provision of student support structures as well as academics.


Meanwhile there is increasing pressure on teachers. Teachers are required to be constantly flexible in their use of new technologies, to deal with a classroom that is often distracted by technology, and to be emotionally available to students as they work and to support administration and instruction. Teachers have to be adaptable because of the speedy changes in education technology.


But it is not only students or teachers that are to be blamed for the difficulties of higher education. The society has changed. Communication, socialization, jobs and the concept of education have evolved in the digital age. Gen Z students are growing up in a society that is facing significant economic instability, technological disruption and always being connected to the internet. Their attitudes and behaviours are a result of their growing up circumstances.


Conflict between generations is not the right answer; it’s about understanding and adaptation. The learning environment in educational institutions needs to establish a space in which discipline is embedded within empathy, technology promotes human interaction, and mentorship is the core of learning. It is important that teachers receive institutional support and training to cope with the dynamic of the classroom, and that student understand the importance of being patient, respectful and engaged in their academics.


Education for Higher Learning is no longer a mere process of assigning degrees; it is an educative process which prepares for the life of a rapidly changing world. As we live in this new normal, the teaching and learning process will not only be determined by the ability of students to achieve academic success, but also by the capacity of teachers to connect with students across generations and nurture understanding, adaptation and respect.


While the classroom of the future could be quite different from the past, one thing is certain – education is fundamentally a human experience and effective learning is as much about relationships as it is about knowledge.
