  • Majorana 1, science journalism, and other things

    While I have many issues with how the Nobel Prizes are put together as an institution, the scientific achievements they have revealed have been some of the funnest concepts I’ve discovered in science, including the clever ways in which scientists revealed them. If I had to rank them on this metric, the first place would be a tie between the chemistry and the physics prizes of 2016. The chemistry prize went to Jean-Pierre Sauvage, Fraser Stoddart, and Ben Feringa for “for the design and synthesis of molecular machines”. Likewise, the physics prize was shared between David Thouless, Duncan Haldane, and John Kosterlitz “for theoretical discoveries of topological phase transitions and topological phases of matter”. If you like, you can read my piece about the 2016 chemistry prize here. A short excerpt about the laureates’ work:

    … it is fruitless to carry on speculating about what these achievements could be good for. J. Fraser Stoddart, who shared the Nobel Prize last year with Feringa for having assembled curious molecular arrangements like Borromean rings, wrote in an essay in 2005, “It is amazing how something that was difficult to do in the beginning will surely become easy to do in the event of its having been done. The Borromean rings have captured our imagination simply because of their sheer beauty. What will they be good for? Something for sure, and we still have the excitement of finding out what that something might be.” Feringa said in a 2014 interview that he likes to build his “own world of molecules”. In fact, Stoddart, Feringa and Jean-Pierre Sauvage shared the chemistry prize for having developed new techniques to synthesise and assemble organic molecules in their pursuits.

    In the annals of the science Nobel Prizes, there are many, many laureates who allowed their curiosity about something rather than its applications to guide their research. In the course of these pursuits, they developed techniques, insights, technologies or something else that benefited their field as a whole but which wasn’t the end goal. Over time the objects of many of these pursuits have also paved the way for some futuristic technology themselves. All of this is a testament to the peculiar roads the guiding light of curiosity opens. Of course, scientists need specific conditions of their work to be met before they can commitment themselves to such lines of inquiry. For just two examples, they shouldn’t be under pressure to publish papers and they shouldn’t have to worry about losing their jobs if they don’t file patents. I can also see where the critics of such blue-sky research stand and why: while there are benefits, it’s hard to say ahead of time what they might be and when they might appear.

    This said, the work that won the 2016 physics prize is of a similar nature and also particularly relevant in light of a ‘development’ in the realm of quantum computing earlier this month. Two of the three laureates, Thouless and Kosterlitz, performed an experiment in the 1970s in which they found something unusual. To quote from my piece in The Hindu on February 23:

    If you cool some water vapour, it will become water and then ice. If you keep lowering the temperature until nearly absolute zero, the system will have minimal thermal energy, allowing quantum states of matter to show. In the 1970s, Michael Kosterlitz and David Thouless found that the surface of superfluid helium sometimes developed microscopic vortices that moved in pairs. When they raised the temperature, the vortices decoupled and moved freely. It was a new kind of … phase transition: the object’s topological attributes changed in response to changes in energy [rather than it turning from liquid to gas].

    The findings here, followed by many others that followed, together with efforts by physicists to describe this new property of matter using mathematics, in harmony with other existing theories of nature all laid the foundation for Microsoft’s February 19 announcement: that it had developed a quantum-computing chip named Majorana 1 with topological qubits inside. (For more on this, please read my February 23 piece.) Microsoft has been trying to build this chip since at least 2000, when a physicist then on the company’s payroll named Alexei Kitaev published a paper exploring its possibility. Building the thing was a tall order, requiring advances in a variety of fields that eventually had to be brought together in just the right way, but Microsoft knew that if it succeeded the payoff would be tremendous.

    This said, even if this wasn’t curiosity-driven research on Microsoft’s part, such research has already played a big role in both the company’s and the world’s fortunes. In the world’s fortune because, as with the work of Stoddart, Feringa, and Sauvage, the team explored, invented and/or refined new methods en route to building Majorana 1, methods which the rest of the world can potentially use to solve other problems. And in the company’s fortune because while Kitaev’s paper was motivated by the possibility of a device of considerable technological and commercial value, it drew from a large body of knowledge that — at the time it was unearthed and harmonised with the rest of science — wasn’t at all concerned with a quantum-computing chip in its then-distant future. For all its criticism, blue-sky research leads to some outcomes that no other forms of research can. This isn’t an argument in support of it so much as in defence of not sidelining it altogether.

    While I have many issues with how the Nobel Prizes are put together as an institution, I’ve covered each edition with not inconsiderable excitement[1]. Given the fondness of the prize-giving committee for work on or with artificial intelligence last year, it’s possible there’s a physics prize vouchsafed for work on the foundations of contemporary quantum computers in the not-too-distant future. When it comes to pass, I will be all too happy to fall back on the many pieces I’ve written on this topic over the years, to be able to confidently piece together the achievements in context and, personally, to understand the work beyond my needs as a journalist, as a global citizen. But until that day, I can’t justify the time I do spend reading up about and writing on this and similar topics as a journalist in a non-niche news publication — one publishing reports, analyses, and commentary for a general audience rather than those with specialised interests.

    The justification is necessary at all because the time I spend doing something is time spent not doing something else and the opportunity cost needs to be rational in the eyes of my employers. At the same time, journalism as a “history of now” would fail if it didn’t bring the ideas, priorities, and goals at play in the development of curiosity-driven research and — with the benefit of hindsight — its almost inevitable value for commerce and strategy to the people at large. This post so far, until this point, is the preamble I had in mind for my edition of The Hindu’s Notebook column today. Excerpt:

    It isn’t until a revolutionary new technology appears that the value of investing in basic research becomes clear. Many scientists are rooting for more of it. India’s National Science Day, today, is itself rooted in celebrating the discovery of the Raman effect by curiosity-driven study. The Indian government also wants such research in this age of quantum computing, renewable energy, and artificial intelligence. But it isn’t until such technology appears that the value of investing in a science journalism of the underlying research — slow-moving, unglamorous, not application-oriented — also becomes clear. It might even be too late by then.

    The scientific ideas that most journalists have overlooked are still very important: they’re the pillars on which the technologies reshaping the world stand. So it’s not fair that they’re overlooked when they’re happening and obscured by other concerns by the time they’ve matured. Without public understanding, input, and scrutiny in the developmental phase, the resulting technologies have fewer chances to be democratic, and the absence of the corresponding variety of journalism is partly to blame.

    I would have liked to include the preamble with the piece itself but the word limit is an exacting 620. This is also why I left something else unsaid in the piece, something important for me, the author, to have acknowledged. After the penultimate line — “You might think just the fact that journalists are writing about an idea should fetch it from the fringes to the mainstream, but it does not” — I wanted to say there’s a confounding factor: the skills, choices, and circumstances of the journalists themselves. If a journalist isn’t a good writer[2] or doesn’t have the assistance of good editors, what they write about curiosity-driven research, which already runs on weak legs among the people at large, may simply pass through their feeds and newsletters without inviting even a “huh?”. But as I put down the aforementioned line, a more discomfiting thought erupted at the back of my mind.

    In 2017, on the Last Word on Nothing blog, science journalist Cassandra Willyard made a passionate case for the science journalism of obscure things to put people at its centre in order to be effective. The argument’s allure was obvious but it has never sat well with me. The narrative power of human emotion, drawn from the highs or lows in the lives of the people working on obscure scientific ideas, is in being able to render those ideas more relatable. But my view is that there’s a lot out there we may never write about if we couldn’t also write about what highs/lows it rendered among its discoverers or beholders, and more so if such highs/lows don’t exist at all, as is often the case with a big chunk of curiosity-driven research. Willyard herself had used the then-recent example of the detection of gravitational waves from two neutron stars smashing into each other billions of lightyears away. This is conveniently (but perhaps not by her design) an example of Big Science where many people spent a long time looking for something and finally found it. There’s certainly a lot of drama here.

    But the reason I call having to countenance Willyard’s arguments discomfiting is that I understand what she’s getting at and I know I’m rebutting it on the back of only a small modicum of logic. It’s a sentimental holdout, even: I don’t want to have to care about the lives of other people when I know I care very well for how we extracted a world’s worth of new information by ‘reading’ gravitational waves emitted by a highly unusual cosmic event. The awe, to me, is right there. Yet I’m also keenly aware how impactful the journalism advocated by Willyard can be, having seen it in ‘action’ in the feature-esque pieces published by science magazines, where the people are front and centre, and the number of people that read and talk about them.

    I hold out because I believe there are, like me, many people out there (I’ve met a few) that can be awed by narratives of neutron-star collisions that dispense with invoking the human condition. I also believe that while a large number of people may read those feature-esque pieces, I’m not convinced they have a value that goes beyond storytelling, which is of course typically excellent. But I suppose those narratives of purely scientific research devoid of human protagonists (or antagonists) would have to be at least as excellent in order to captivate audiences just as well. If a journalist — together with the context in which they produce their work — isn’t up to the mark yet, they should strive to be. And this striving is essential if “you might think just the fact that journalists are writing about an idea should fetch it from the fringes to the mainstream, but it does not” is to be meaningful.


    [1] Not least because each Nobel Prize announcement is accompanied by three press releases: one making the announcement, one explaining the prize-winning work to a non-expert audience, and one explaining it in its full technical context. Journalism with these resources is actually quite enjoyable. This helps, too.

    [2] Im predominantly a textual journalist and default to write when writing about journalistic communication. But of course in this sentence I mean journalists who arent good writers and/or good video-makers or editors and/or good podcasters, etc.

  • Let’s allow space missions to be wonderful

    Finally some external validation. After months of insisting Sunita Williams and Barry Wilmore aren’t “stuck” or “stranded” in the International Space Station, after Boeing Starliner’s first crewed flight test went awry, the two astronauts have themselves repudiated the use of such words to describe their mission profile so far. On February 18, Moneycontrol quoted a CNN report to say:

    In an interview with CNN, Wilmore said they are neither abandoned nor stuck. “We come prepared and committed,” he stated, adding that all ISS astronauts have emergency return options. Williams also reflected on their space experience, saying, “Floating in space never gets old.”

    Williams’s statement isn’t bravado just much as the use of “stranded” isn’t a matter of describing what’s right in front of us. Crewed missions to space are always more complicated than that. That’s why Boeing picked Williams and Wilmore in the first place: they’re veteran astronauts who know when not to panic. To quote from a previous post:

    The history of spaceflight — human or robotic — is the history of people trying to expect the unexpected and to survive the unexpectable. That’s why we have test flights and then we have redundancies. For example, after the Columbia disaster in 2003, part of NASA’s response was a new protocol: that astronauts flying in faulty space capsules could dock at the ISS until the capsule was repaired or a space agency could launch a new capsule to bring them back. So Williams and Wilmore aren’t “stuck” there: they’re practically following protocol.

    For its upcoming Gaganyaan mission, ISRO has planned multiple test flights leading up the human version. It’s possible this flight or subsequent ones could throw up a problem, causing the astronauts within to take shelter at the ISS. Would we accuse ISRO of keeping them “stuck” there or would we laud the astronauts’ commitment to the mission and support ISRO’s efforts to retrieve them safely?

    … “stuck” or “stranded” implies a crisis, an outcome that no party involved in the mission planned for. It creates the impression human spaceflight (in this particular mission) is riskier than it is actually and produces false signals about the competencies of the people who planned the mission. It also erects unreasonable expectations about the sort of outcomes test flights can and can’t have.

    Narratives matter. Words don’t always describe only what the senses can perceive. Certain words, including “stuck” and “stranded”, also impute intentions, motive, and agency — which are things we can’t piece together without involving the people to whom we are attributing these things (while ensuring they have the ability and opportunity to speak up). Wilmore says he’s “committed”, not “stuck”. When Williams says “floating in space never gets old”, it means among other things that she’s allowed to define her journey in that way without only navigating narratives in which she’s “stranded”.

    In fact, as we make more forays into space — whether specific tasks like taking a brand new crew capsule for its first spin, guiding robots into previously uncharted areas of space or ourselves going where only robots have been before — we need to stay open to the unexpected and we need to keep ready a language that doesn’t belittle or diminish the human experience of it, which by all means can be completely wonderful.

    Finally, I support restricting our language to what’s right in front of us in the event that we don’t know, which would be to simply say they’re in space.

  • Do the poor want to be poor?

    ‘Justice Gavai’s comments on freebies overlook people’s struggle for survival: Brinda Karat’, The Hindu, February 14, 2025:

    CPI(M) Polit Bureau member Brinda Karat said the recent remarks on freebies by Supreme Court Judge Justice B.R. Gavai fails to recognise the struggle of India’s labouring class for survival in the face of “rampant unemployment, precarious nature of work and low wages”.

    In an open letter to Justice Gavai on Friday (February 14, 2025), Ms. Karat urged him to reconsider his comments as they could prejudice social opinion against those receiving social benefits from the government.

    Justice Gavai made the remarks on Wednesday while hearing petitions on the shortage of night shelters for the urban homeless in the national capital. During the hearing, he had asked whether untrammelled freebies lull the poor into a parasitic existence, depriving them of any initiative to find work, join the mainstream, and contribute to national development.

    Kudos to Brinda Karat for raising this counterargument and for asking Justice Gavai to reconsider his views. Aside from “prejudicing social opinion”, Justice Gavai’s observation also goes against a fact that social scientists and behavioural economists alike have repeatedly established: the poor don’t want to stay poor, they don’t like to stay poor. This extends to the degree to which they are comfortable about leading a “parasitic existence” as well as vexes the allegation that they are devoid of initiative. This is why, Justice Gavai may be interested in being reminded, researchers and policymakers have found the most effective welfare scheme in various countries worldwide to be simply giving poorer people money to spend as they see fit. Studies of social welfare schemes in low- and middle-income countries have even found that giving households money to spend doesn’t affect whether their working-age members want to work. If Justice Gavai’s concern is that the poor stay poor and don’t seem to be able to exit poverty, he should redirect the force of his words at how easy it has become to slip into destitution in contemporary India and at initiatives that render direct benefit transfer schemes — including handing out money — more frictionless.

  • Subtracting from science funding

    ‘NavIC’s hurdles project govt’s reluctance to fund innovation’, Hindustan Times, February 7, 2025:

    India … chose a more cautious path. For decades, we’ve been telling ourselves that we’ll invest in science “when we’re economically better off.” It’s both prudent and a paradox. How do you become economically better off without investing in the very thing that drives development in the first place? It’s like waiting to plant a tree until you’re sure it will bear fruit tomorrow. That hesitation shows in the numbers: India spends just 0.6% of its GDP on scientific research. For comparison, China spends over 2.5%, and the United States spends 3%.

    Charles Assisi has an interesting analysis of the partial failure of the NVS-02 mission. (‘Partial’ because ISRO is currently looking to repurpose the satellite. The terms of this exercise aren’t yet clear.) “When you’re constantly short of funds, every setback feels heavier” — spot on. In fact, my cynical self inclined is inclined ask him if he really believes the present government is interested in stoking development when it has been making the right noises, but only noises, about increasing the private sector’s contribution to R&D expenses while allowing the growth of the public sector’s contribution to grow more slowly than the GDP.

    This said, I’m more curious about the final sentence of the same paragraph:

    Worse still, when you dig into the details, much of India’s scientific budget is buried within defense spending, which means it doesn’t always trickle down to civilian applications or long-term innovation.

    Unless growth in defence spending has somehow exactly matched decline in spending on R&D, I’m curious how defence alone can be said to have subtracted from science. Perhaps it did, perhaps it didn’t, but I wouldn’t have used the argument because it presumes whatever that money was spent on didn’t have civilian interests at heart. It’s a strawman. It isn’t a crime without a victim either because of the notion that the scientific enterprise is incapable of delivering anything less than “civilian applications or long-term innovation”, even with sufficient funding. The arc of the scientific enterprise doesn’t bend towards the public interest by itself.

    It’s also possible that what the R&D budget lost, the nuclear establishment gained — and I could get behind that. But beyond the subtraction itself, the question of which ministry or sector benefited is meaningless. The finance ministry makes its allocations from a large pool, and it only makes sense to talk about what science lost in terms of what science lost, rather than because X gained rather than Y.

  • Learning with ChatGPT

    I have access to the premium version of ChatGPT, and every day I ask it a few questions about concepts in physics that I’d like to know more about. Yesterday, for example, I learnt the difference between quenching and annealing and later about the Weierstrass function, which it was also able to plot after some difficulty.

    I have found using ChatGPT in this way to be a valuable learning tool, and I imagine there are already people out there who are repackaging instances of ChatGPT to be autonomous ‘teachers’ for students looking to learn something, although not one that can be a school-based learning. The only major human input is knowing what questions to ask and when. This activity can be split into two modes: one when the student asks doubts and follow-up questions and the other when the ‘learning programme’ determines the pace at which to introduce new concepts.

    One of my jobs at The Hindu is to get explanatory articles for concepts in (pure) science. I recently attempted one on amplifiers, which required me to explain the working of a NPN bipolar junction transistor, a device I’d until then been happy to leave behind in my high school classroom. I turned to ChatGPT, asking for a visualisation of the transistor, and it obliged. I’m a visual learner and having access to the tool made a big difference.

    I have a background in engineering plus more than a decade’s experience in spotting red flags in scientific papers, and I imagine anyone with these skills will have an easier time navigating ChatGPT’s answers. If a school education can bring a person to this point, ChatGPT can be a valuable guide for the time after. All we need is a guarantee from OpenAI that the tool doesn’t hallucinate or that it hallucinates in specific contexts, and definitely not above a certain rate.
