15 years at IISER Pune – Journey so far

Today, I complete 15 years as a faculty member at IISER-Pune. I have attempted to put together a list of some lessons (based on my previous writings) that I have learnt so far. A disclaimer to note is that this list is by no means a comprehensive one, but a text of self-reflection from my viewpoint on Indian academia. Of course, I write this in my personal capacity. So here it is..

  1. People First, Infrastructure Next
    As an experimental physicist, people and infrastructure in the workplace are of paramount importance. When I am forced to prioritize between them, I have chosen people over infrastructure. I am extremely fortunate to have worked with, and continue to work with, excellent students, faculty colleagues, and administrative staff members. A good workplace is mainly defined by the people who occupy it. I do not neglect the role of infrastructure in academia, especially in a country like India, but people have a greater impact on academic life.
  2. Create Internal Standards
    In academia, there will always be evaluations and judgments on research, teaching, and beyond. Every academic ecosystem has its own standards, but they are generalized and not tailored to individuals. It was important for me to define what good work meant for myself. As long as internal standards are high and consistently met, external evaluation becomes secondary. This mindset frees the mind and allows for growth, without unnecessary comparisons.
  3. Compare with Yourself, Not Others
    The biggest stress in academic life often arises from comparison with peers. I’ve found peace and motivation in comparing my past with my present. Set internal benchmarks. Be skeptical of external metrics. Strive for a positive difference over time.
  4. Constancy and Moderation
    Intellectual work thrives not on intensity alone, but on constancy. Most research outcomes evolve over months and years. Constant effort with moderation keeps motivation high and the work enjoyable. Binge-working is tempting, but rarely effective for sustained intellectual output.
  5. Long-Term Work
    We often overestimate what we can do in a day or a week, and underestimate what we can do in a year. Sustained thought and work over time can build intellectual and technical monuments. Constancy is underrated.
  6. Self-Mentoring
    Much of the academic advice available is tailored for Western systems. Some of it is transferable to Indian contexts, but much of it is not. In such situations, I find it useful to mentor myself by learning from the lives and work of people who have done extraordinary science in India. I have been deeply inspired by many people, including M. Visvesvaraya, Ashoke Sen, R. Srinivasan, and Gagandeep Kang.
  7. Write Regularly—Writing Is Thinking
    Writing is a tool to think. Not just formal academic writing, but any articulation of thought, journals, blogs, drafts, clarifies and sharpens the mind. Many of my ideas have taken shape only after I started writing about them. Writing is part of the research process, not just a means of communicating its outcomes.
  8. Publication is an outcome, not a goal Publication is just one outcome of doing research. The act of doing the work itself is very important. It’s where the real intellectual engagement happens. Focus on the process, not just the destination.
  9. Importance of History and Philosophy of Physics
    Ever since my undergraduate days, I have been interested in the history and philosophy of science, especially physics. Although I never took a formal course, over time I have developed a deep appreciation for how historical and philosophical perspectives shape scientific understanding. They have helped me answer the fundamental question, “Why do I do what I do?” Reflecting on the evolution of ideas in physics—how they emerged, changed, and endured—has profoundly influenced both my teaching and research.
  10. Value of Curiosity-Driven Side Projects
    Some of the most fulfilling work I’ve done has emerged from side projects, not directly tied to funding deadlines or publication pressure, but driven by sheer curiosity. These projects, often small and exploratory, have helped me learn new tools, ask new questions, and sometimes even open up new directions in research. Curiosity, when protected from utilitarian pressures, can be deeply transformative.
  11. Professor as a Post-doc
    A strategy I found useful is to treat myself as a post-doc in my own lab. In India, retaining long-term post-docs is difficult. Hence, many hands-on skills and subtle knowledge are hard to transfer. During the lockdown, I was the only person in the lab for six months, doing experiments, rebuilding setups, and regaining technical depth. That experience was invaluable.
  12. Teaching as a Social Responsibility
    Scientific social responsibility is a buzzword, but for me, it finds its most meaningful expression in teaching. The impact of good teaching is often immeasurable and long-term. Watching students grow is among the most rewarding experiences in academia. Local, visible change matters.
  13. Teaching Informally Matters
    Teaching need not always be formal. Informal teaching, through conversations, mentoring, and public outreach, can be more effective and memorable. It is free of rigid expectations and evaluations. If possible, teach. And teach with joy. As Feynman showed us, it is a great way to learn.
  14. Foster Open Criticism
    In my group, anyone is free to critique my ideas, with reason. This open culture has been liberating and has helped me learn. It builds mutual respect and a more democratic intellectual space.
  15. Share Your Knowledge
    If possible, teach. Sharing knowledge is a fundamental part of academic life and enriches both the teacher and the learner. The joy of passing on what you know is priceless.
  16. Social Media: Effective If Used Properly
    Social media, if used responsibly, is a powerful tool, especially in India. It can bridge linguistic and geographical divides, connect scientists across the world, and communicate science to diverse audiences. For Indian scientists, it is a vital instrument of outreach and dialogue. My motivation to start the podcast was in this dialogue and self-reflection.
  17. Emphasis on Mental and Physical Health
    In my group, our foundational principle is clear: good health first, good work next. Mental and physical well-being are not optional; they are necessary conditions for a sustainable, meaningful academic life. There is no glory in research achieved at the cost of one’s health.
  18. Science, Sports, and Arts: A Trinity
    I enjoy outdoor sports like running, swimming, and cricket. Equally, I love music, poetry, and art from all cultures. This trinity of pursuits—science, sports, and the arts—makes us better human beings and enriches our intellectual and emotional lives. They complement and nourish each other.
  19. Build Compassion into Science
    None of this matters if the journey doesn’t make you a better human being. Be kind to students, collaborators, peers, and especially yourself. Scientific research, when done well, elevates both the individual and the collective. It has motivated me to humanize science.
  20. Academia Can Feed the Stomach, Brain, and Heart
    Academia, in its best form, can feed your stomach, brain and heart. Nurturing and enabling all three is the overarching goal of academics. And perhaps the goal of humanity.

My academic journey so far has given me plenty of reasons to love physics, India and humanity. Hopefully, it has made me a better human being.

Writing in the age of AI

A contemporary question of interest: How can artificial intelligence (AI) influence writing?

Writing has two consequences – 1) a writer processing information and communicating it to an audience; 2) a reader processing the author’s information.

The first part has an element of personal touch, just like any art or craft (for example, pottery). One does write (or create a pot) partly because it gives some pleasure and helps one to understand something in the process. There is a gain of knowledge in writing. This pleasure and wisdom through writing cannot be replaced by an external agency like AI. This is because external tools like AI are assistants of thought, not internal replacements of thought. In that sense, no external tool can replace any amateur activity because something is done for the sake of the process. Writing as a tool of self-reflection cannot be replaced by something external.

So, where is the threat? Actually, it is professional writing which is under partial threat from AI. Wherever the end product is more important than the process of writing, AI can gain prominence, provided it is accurate. It is still a partial threat because a professional writer can create questions and combinations that may arise out of individual experiences. Those lived experiences are derived from “life“, and AI cannot be a substitute for such an internal experience.

Writing, like many human endeavors, is both internal and external. The former makes us human, and that is hard to replace. After all, the A in AI stands for artificial.

Questions as a class assignment

Over the years, I have been giving student assignments to write about their questions (rather than answers to my Qs).

Snapshot of email to my class below.

I have found some gems in the process and importantly reduces the ‘burden’ of single right answers. Student feedback on this process has been positive.

Even in the ChatGPT era, it is the quality of Qs that determines the answer, and in this assignment, students are free to choose their Qs as per their interest and experience connected to what I teach…something harder for ChatGPT to grasp (as of now).

Interesting times ahead.

Questions: Substance and Form

To wonder is to be human. At the heart of wondering is questioning. As an individual and a collective, encouraging people to ask questions is one of the most important things we can do. Start with your children or young people around you. Encourage them to question you. Try to answer them honestly. If you do not know the answer, explore the answer with them. Emphasize that no answer is complete and is subject to revision upon new evidence and ideas.
In my opinion, this process is the safest training you can give them as an adult and help them become informed citizens.

Along the way, teach them two things: 1) how to formulate a question and 2) pay attention to the tone of the question they ask.

Formulating a good question is a challenging task and requires iteration. Iterations mean patience. So, asking a good question is a training in patient thinking. Discourage rushing through. That does not mean the upper time bound is infinite. This means you shouldn’t settle for the default question. Question the question.

Next is the tone of the question. It is the tone which determines the intention of the question. If your intention is grounded in humility, curiosity and transparency, you will have a better chance of obtaining an answer. A question asked in a condescending tone generally discourages people from answering, even if their intention is not to conceal.

Of course, these are not general rules but guidelines that may be useful.

Conclusion:
Pay attention not only to the substance of your question but also to the form of your question. A questioning mindset can be extrapolated to your everyday thinking. Gradually, it will become a way of life.
Learning is more important than ego. When you realise this, questions become a great tool to explore the world.

Thinking in a Classroom

As I conclude my Optics course this week (40+ hrs, ~80 physics majors ), I have an opinion to express. There is no substitute for in-person human interaction and learning. This form of interaction is not to downplay the role of technology in education, but somehow, as humans, we still connect better in reality than in virtual space.

I have been formally teaching for the past 14 years or so, and for a couple of semesters, I have also taught online courses during the pandemic. During these years, I have learnt that technology can add significant value to teaching but cannot be a substitute for a teacher or a student. As we teach a class with a reasonable number of students, we experience live feedback from each other, which has no equivalent during an online interaction. Humans take this feedback for granted and assume we can replicate it in a virtual space with limited success. Such feedback may have a deeper connection to the evolutionary biology of human beings.

This feedback loop in a live class does not make teaching or learning a perfect act of communication. But it brings in a form of dissipative coherence, which indicates that the whole class, including the teacher, is thinking synchronously at the moment of exposition. I have deliberately used the word ‘dissipative’ because there is always some intellectual noise in the background. The beauty of this noise is that it adds up with the information under discussion and amalgamates with the topic of exposition. This combination is the uniqueness of learning. At that moment in the class, we are all thinking about a topic, but noise in an individual mind combines with the issue at large and possibly emerges as a new thought. This divergence of thinking at a personal level, combined with real-time feedback, makes a live class alive.

And at that hour, it becomes a single living entity with a single meta-brain.
