My Response to Kaplan

Recently, anthropic co-founder Jared Kaplan, who has a background in physics, made the following comment, which was circulated on X. Below is the excerpt:

Below is my response:

A Remarkable Human Being = Remarkable Attribute(s) + Human Being

The first term in the RHS can be replaced by AI, but not the second term, for the following reasons.

  1. Machines, including AI, can surely change the way humans think, work and live, but it will be difficult to match human connection. A machine can enhance human life, but can it inspire a human life?
  2. People inspire people. Ask a child or any adult who inspires them. It will generally be a fellow human being. Machines add value, but human beings represent a valuable life. We utilize the former, and get inspired by the latter. It is this inspiration that propels people forward to do things that may further turn out to be remarkable. This contribution is not easily quantified, but it is hard to gauge a human life without inspiration.
  3. People like Ed Witten, Ashoke Sen and Terry Tao add value to humanity not only through their work and ideas, but their lives show that human beings can think and do something remarkable. It assures human beings that, individually, our species can do something good.
    Human beings derive meaning by interacting with fellow human beings and are inspired by the interaction. They also get inspired and draw meaning by studying people from the past. A human’s search for meaning and purpose is always in the background of other human beings. We are 8 billion plus, and it is hard to ignore each other.

It will be very unusual to find a serious student of theoretical physics who says I am inspired to live by ‘ChatGPT’.

Probably a young Kaplan, too, was inspired by a fellow human being! So, my question to Mr. Kaplan.
Who inspired you to do physics?

26 Jan – Indian Republic Day…and a few more

Happy Republic Day to all my fellow Indians !

26th Jan is also an important day in the history of physics/engineering –

 Oliver Hutchinson — subject of the earliest photograph of a television image, early 1926. National Media Museum (for image on right). Image from: The International Journal for the History of Engineering & Technology 84 (2): 227–47.

26th Jan 1926 – J.L. Baird “demonstrated television at his premises in Frith Street, London, to about forty people including members of the Royal Institution…..The Times was the only newspaper invited, and its reporter published the story on 28 January”. This exactly a 100 years today !

26th Jan 1939 – Niels Bohr publicly announced nuclear fission, specifically the splitting of the uranium atom.

26th Jan 1954Morris Tanenbaum et al. at Bell Laboratories showed a working silicon transistor.

C V Raman and long term thinking

A small sampling of Raman’s publication. These papers are related to light scattering and form the foundation on which he made his famous discovery. Raman wrote more than 400 research papers in his lifetime (apart from monographs, lectures and public talks). Writing such a series of papers on a particular topic can be observed throughout his career.

A note to young scholars: intellectual monuments are built this way: thought after thought, day after day, paper after paper. Never underestimate what can be achieved with consistent, honest effort.

Brillouin on Sommerfeld

Everybody wondered (and still wonders) why the Stockholm committee systematically ignored Sommerfeld’s pioneer work in modern physics. Such an omission is actually impossible to understand.”

Leon Brillouin, in the foreword of his book WAVE PROPAGATION AND GROUP VELOCITY (1959)

Brillouin further mentions the teachers who taught him, and rates Sommerfeld among the best:

I had the great privilege of attending, as a student, lectures given by some prominent physicists, such as H. A. Lorentz, H. Poincaré, and P. Langevin. But I was especially impressed by Sommerfeld’s mastery as a teacher.

Conversation with Srubabati Goswami

Srubabati Goswami is a pioneering Indian physicist specializing in high-energy physics, particularly neutrino physics. She is probably the first Indian woman to earn a PhD in neutrino oscillations from the University of Calcutta. She advanced research at Physical Research Laboratory, Ahmedabad (PRL), Saha Institute of Nuclear Physics, and Harish-Chandra Research Institute before becoming Senior Professor at PRL. A fellow of India’s three science academies, she unravels neutrino mysteries and champions women in science.

In this episode, we explored her intellectual history and her remarkable journey as a physicist.

Five Aspects of the Fifth Pillar – A Philosophical Perspective

In reference to a recent article on higher education in the Economic Times, a well-known tech entrepreneur and philanthropist wrote the following on X/Twitter: “75% of Indian higher education institutions still not industry-ready. Lot of work left to transform. But the 21st century requires education, research, innovation, and startups as four pillars of a university.”

This is a thought I do support, but I think there is one more important meta-pillar, perhaps a ‘foundation’ on which all these pillars are standing, and that is called ethics. Below are five aspects of ethics that I think need further attention.

  1. If one observes some of the major contemporary and pressing problems in our world, they can be connected to the ethical aspects of how humans function. A vital part of our educational system should re-emphasize this connection and make it central to everything that is done in a society.
  2. Ethics has two important elements to it: first, it has a philosophical grounding and connects to how humans function in a society. Second, it has an important connection to how trust in a society can be developed. Most of the discussions on ethics generally focus on the first element from a morality perspective, whereas the second point has an equally important utility and an economic connection.
  3. Ethical principles have great utility. It is important that we never keep it as an implicit aspect of human endeavour. Instead, we should start everything on the ethical grounds and build it up from there, including businesses, because a strong ethical foundation probably would be the best thing to happen for economic progress in any society, because trust is so important among human beings, and it is one thing that probably brings humans together. In the long run, the meaning of ‘prosper’ critically depends on the meaning of ethics. Being prosperous without being ethical is detrimental to any human pursuit. Zero-sum games are exciting, but in the limit of many games, the number of people who lose will be far more than the people who win. Instead, cooperative games have much larger dividends to all players and are inherently connected to a concept called as double thank you moment.
  4. The philosophy of ethics is something which the world has to revisit in greater detail, especially in an era where technological implications are driving human life in directions which we have not anticipated. One may think that raising ethical issues might hinder progress, but my argument here is that, instead of hindrance, one should look at it as an important requisite for human societies to not only survive but also to flourish. Large human endeavours cannot sustain without trust, and that trust is reinforced through ethical behaviour.
  5. Without ethical implications being factored in, it would be hard to really design anything related to technology. A case in point is the social media restrictions in countries such as Australia. Technology has the amazing capability to move fast before the philosophical debates can come in, but it does not mean that philosophy has to be completely ignored. The downstream of a scientific idea can become a product in a market, and positively impact society, but this evolution has a fellow-traveller, and that is ethics. The feedback loop is incomplete without the ethical considerations, and therefore, it should be looked at as an important ingredient in any human design.

There is an inherent connection between cooperation and trust, and that is founded on an ethical principle. The world requires an ethical recap, and it should be part of individuals, institutions, and governments. There is a rich history of ethics in all the cultures across the world, and it is worth revisiting them in a new light. Perhaps it is high time that we “Make Ethics Great Again.”
