Sanskrit subhashita – don’t waste

Here is a Sanskrit subhashita that I like.

वृथा वृष्टि: समुद्रेषु वृथा तृप्तेषु भोजनम्।

वृथा दानम् धनाढ्येषु वृथा दीपो दिवाऽपि च॥

LLMs are getting better at translations.

Below is a comparison of translations on 2 platforms

English Translation from perplexity AI:

Rain over the ocean is wasted, food for those who are already full is wasted; Charity to the wealthy is wasted, and a lamp during the daytime is wasted.

English translation from ChatGPT:

Rain over the ocean is in vain, food for one who is already full is in vain; Charity to the wealthy is in vain, and a lamp during the day is also in vain.

ChatGPT – an experiment

Below is a small experiment with ChatGPT (GPT-4o, which is OpenAI’s most advanced model as of July 2025).

I asked for thoughts (from authentic sources) from Indian writers on the nature of the writing process (handwriting vs typewriting).

It confidently gave me quotations from Rabindranath Tagore, R.K. Narayan and U.R. Ananthmurthy. I was intrigued, and below is my conversation:

me: list the quotes from Indian writers above and give the exact sources

Chatgpt: I couldn’t find reputable sources for the exact quotes I previously suggested by Indian writers—so it’s safer to reconsider them.

This is something I have been observing with LLM chatboxes, especially when it comes to the sources that may not be mainstream. One may even say it is hallucinating, but after enquiring further, it said:

The quotes I initially provided appear to be popular paraphrases or second-hand interpretations, but none could be verified in primary texts or reliable interviews.

Then, it asked me if I wanted to use authentic sources to be presented to corroborate the initially mentioned sources. I said yes, and below was its reply:

Here are verified quotes from Rabindranath Tagore, with clear attributions to reliable sources—unfortunately, I couldn’t locate authenticated quotes for other Indian writers on writing methods

The quotes that it gave were peripheral to my initial question. It identified two to three quotations, but none of them were directly connected to my initial query.

There may be at least 2 hypotheses that I can draw from this, which need further testing:

  1. ChatGPT and its kind may be getting trained more intensely on sources that are mainly anglophonic, and its geographical distribution of sources may be skewed. Online literary sources from countries such as India may not be as dense as, say USA, the UK or even some European countries. Will depositing more authentic sources online, including their translations, help the authentic discovery of information from countries such as India?
  2. With the current developments and model training, there may already be a bias in the answers that LLM chatbots give. It may reinforce many viewpoints from Western repositories that may sometimes be disconnected or irrelevant to the user outside Western geographies. In that sense, new information is being built on old information. Are we entering a stage where data deposition asymmetry is creating an asymmetry of discovery?

I know these questions are not trivial to answer, but for LLM chatboxes to be authentic, they need to address questions with proper citations. I know some of them are trying to do that (eg, perplexity AI), but I find the links it provides for certain focused questions are not up to the mark.

My inference:

  1. I am cautiously optimistic about the developments and achievements in source-based LLM interfaces, especially when you feed an authentic source (eg, NotebookLM).
  2. But LLM chatboxes may be hyped when:
    • It comes to its capability of sourcing authentic information, and
    • The immediacy of replacements of existing knowledge systems.
  3. LLM chatboxes should be treated as an experimental tool for utilitarian tasks where the information can be verified independently.
  4. It is important to take the bottom line of ChatGPT seriously: ‘ChatGPT can make mistakes. Check important info.

ConForce 25 – highlights

From 15th to 18th June 2025, I attended a focused meeting called ConForce.

The location was at an interesting place: Casuarina Resort Park- Kurunji, which is about 70 km from Pune. It was a scenic and raw place, with an amazing landscape. The resort facilities were ok with limited facilities, but the landscape was just breathtaking. It rained almost all the time, but it created a wonderful visual across the horizon with lush green patches of mountains and grey clouds (see image).

The main theme of the meeting was related to force spectroscopy, with a greater tilt towards biophysical applications. I spoke in the optical tweezers section and enjoyed the discussion with various participants and speakers. Specifically, I presented some of our recent, unpublished work on optical binding and its optical perturbation.

YouTube as an Archival Source

There are several models for using YouTube. One of them is to use it as a substitute for television and media outlets. This is where the number of views, subscriptions, and reach becomes important.

Another model is to harness YouTube as an archival source that is open to the public. This is one of the crucial elements of a platform that is easily accessible and, importantly, searchable. Such a platform becomes a repository for many informal academic discussions and interactions.

The archive model is an important category, especially if there is no need to generate revenue from the content deposited on the platform. A crucial aspect is that it can be accessed across the world and, in that sense, represents truly open-access content without paywalls, publication charges or subscriptions. Therefore, I am glad to see that many Indian academic programs, including NPTEL, ICTS, Science Activity Center/Media Center at IISER-Pune and many others are utilizing platforms such as YouTube to post their lectures and talks. Also, many individual academics in India are gradually using YouTube to discuss their work, in the context of research, teaching and entrepreneurship.

This development is slowly turning out to be an invaluable resource that can reach a large audience. Although YouTube is one of the most well-known platforms, many other platforms in the context of social media can also be tapped to spread knowledge. Given their reach and simplicity of use, both for creators and users, these tools become important in a vast country such as India.

As audio-visual public platforms join hands with artificial intelligence tools, they can positively (hopefully) affect how people, especially students, consume educational content. Going forward, I anticipate language translation through direct dubbing to be a game-changer. It could attract many new viewers who have been hesitant to watch technical content simply because it was in a foreign language. Of course, on these platforms, the noise is equally high compared to the signal, and therefore, curating good, targeted resources will be vital. Also, these platforms cannot be treated as a substitute for formal education, but as an extension or complementary source for research and education.

Interesting times ahead.

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.
