  • Review: ‘Oppenheimer’ (2023)

    Oppenheimer was great. I really liked it. I don’t have a review as much as some notes that I took during the film that I’d like to share. But before diving into them, I should say that I got a certain impression of the film before I watched it based on all the reviews, the hot-takes, and the analyses, and it was almost entirely at odds with my final experience of it. How happy am I to have been wrong.

    SPOILERS AHEAD

    1. “Brilliance makes up for a lot.” – The idea that genius is an excuse to overlook other flaws, a famously problematic notion among scientists, as we’ve seen of late, recurs non-ironically throughout the film. But it’s also the sort of criticism that, while it’s important to take note of, doesn’t seem interesting vis-à-vis the film itself. The film shows Oppenheimer as he was, warts and all – and there’s value in that – living and working in a time that encouraged such thinking. The point was neither to redeem him nor make sure we ‘learn’ that such thinking is worthy of discouragement, in much the same way it doesn’t discuss who occupied the land where the Trinity test was conducted.

    (This said, it did strike me as odd why the film chose not to show the images of the bomb’s consequences in Japan, as they were being displayed to an audience that included Oppenheimer. I can’t say I agree that us observing him as he reacted to those images was more important.)

    2. Military and science – This is a tension that’s also been made clear in several historical accounts of the Manhattan Project, of the working culture among scientists clashing with how the military operates, and how, in the course of this contest, each side perceived profound flaws in the way the other achieved its objectives. One is, or claims to be, democratic (epitomised in the film by Oppenheimer persuading Teller to stay back at Los Alamos) while the other prizes brutal efficiency and a willingness to get its hands ‘dirty’ because of the clear apportionment of blame (irrespective of whether that’s really possible from the PoV of today).

    3. “How could this man who saw so much be so blind?” – Strauss’s comment in the beginning sets up the kind of person Oppenheimer was very well. The real-world Oppenheimer was often disrespectful, flippant towards other people’s opinions or feelings. But in the film, this disposition is directed almost always at Strauss, so it’s possible to come away thinking that Oppenheimer just believed Strauss alone to be worthy of some disdain. But Strauss’s comment hints at Oppenheimer’s hubris very well, and so concisely.

    4. “Scientists don’t respect your judgment” – Another comment of Strauss’s, which although we see by the end of the film was born largely out of an inflated self-importance, also spoke, I thought, to the tension between how the scientists and the soldiers operate and to the sense of unease among some in the military that comes of looking outside-in into the Manhattan Project, until of course the bomb was delivered.

    5. A science and military complex – Vannevar Bush is ‘represented’ in the film. After the war ended, he was to famously advocate for the US investing in blue-sky research, that such research, while delivering no short-term gains, would in the longer one hold the country in good stead on a variety of advanced technologies. The complex still operating today is the military-industrial one, but science during the war became a glue holding them together. And it’s interesting to get such a well-dramatised view of the tensions through which these two enterprises were reconciled.

    6. Tension ahead of Trinity – This is the principal reason I liked Oppenheimer. I’ve read a lot (relatively) about how the bomb came to be, but one thing all of those accounts lacked is such a faithful – or what I imagine is a faithful – description of the emotions at play as the bomb was built, tested, and reckoned with. When that man’s fingers tremble over the big red button that would detonate the weapon, I was trembling in my seat. The nervousness, the anger, the frustration, even the complementary nonchalance of Teller and Feynman. This is very difficult to get through scholarship.

    7. Nolan’s comment – In several interviews before the film’s release, Nolan said he believed Oppenheimer was the “greatest person” to have ever lived. I assumed before watching the film that this was an insight into the sort of film Oppenheimer would be, with hero worship and its attendant rituals. But in the end, the comment was so irrelevant to the experience of the film.

    8. What is a nuclear weapon? – To me, Oppenheimer‘s principal triumph is that, through the eyes of its eponymous protagonist, it conveys what it means for there to be such a thing as a nuclear weapon. It’s fundamentally the breaking of the strong nuclear force between two nucleons, but it’s also, to paraphrase something Strauss says in his angry tirade near the end, the irreversible act of letting the nuclear genie out of the bottle and everything that entails. It’s power and therefore a herald of cynical politics. It’s classified information and therefore a source of mis- or dis-trust. (“If you create the ultimate destructive power, it will also destroy those who are near and dear to you” – Nolan.) It’s knowledge of another country’s power and intent. It’s a demonstration of its scientists’ ability to channel their talents as well as their moral bearings. It’s the weapon to reshape all wars. So forth.

    9. Shockwave in the gymnasium – This was such an excellent, poignant scene, when Oppenheimer is going through the motions, or what he thinks ought to be the motions, and the place goes quiet just as it did when the Trinity shot succeeded. Then, as he is walking out, the sound of his audience’s cheering hits him like a shockwave. Such a well-conceived metaphor for the bomb’s political nature, and a cementing of Oppenheimer’s epiphany that there’s really nothing he can do to control how it will be used.

    10. Partial fictions – Strauss’s vendetta against Oppenheimer isn’t borne out in the historical record, including the fact that Strauss was the one to hand the FBI the all-important file (via Borden). This sadly constitutes the same sort of mistake that films of lower calibre do: claiming to be based on real-world events (or, as in this case, a book documenting real-world events) but then fictionalising some small detail. The effect is for a watcher to be left wondering what else didn’t exactly happen, which they won’t know about unless they specifically check. In Oppenheimer, this is true of parts of the Strauss storyline, the Oppenheimers’ parenting skills, how concerned the physicists really were of the bomb setting “the air on fire”, and, irony of ironies, it all begins with a literal poisoned fruit.

    (A couple inconsistencies are in my opinion worth singling out, despite being quite minor: (i) when the Trinity shot succeeds, Oppenheimer is shown being accosted by George Kistiyakowsky demanding the $10 he bet Oppenheimer the previous night that the test would go through. Oppenheimer says “I’m good for $10” and hands him a bill, but in reality he didn’t have the money. But that’s not all. In that moment, Oppenheimer would later recall mulling those famous words from the Gita, only for Kenneth Bainbridge to have been plainer: “Oppie, now we’re all sons of bitches.” (ii) When Chevalier tells Oppenheimer that Eltenton can help pass information through to the Soviets, Kitty comes to the kitchen not wanting the two of them to be alone and is also the one to tell Chevalier that his proposal constitutes treason. In the film, Kitty enters the kitchen after this conversation has concluded. This is worth pointing out because, in the film itself, she’s always been the better judge of character than Oppenheimer.)

    11. Compartmentalisation – The concept of compartmentalisation appears throughout the film in the context of maintaining the secrecy of the Manhattan Project. But as it happened, a certain loss of compartmentalisation had to transpire for the project’s physicists to actually want to build a bomb – something that happened, by some accounts, at a meeting on April 15, 1943, when Robert Serber clarified to those present at the Los Alamos site that they were to build a nuclear weapon. When the physicists set about their task with gusto, they surprised Enrico Fermi, who then told Oppenheimer: “I believe your people actually want to make a bomb.” A terribly profound comment.


    Addendum

    Oppenheimer forced me to confront and question a little knot of apprehension that had taken root within my mind when it released. It was fed mostly by the fact that the film would expose to a very large number of people a world of information that had taken many others (myself included) a lot more time to find, learn, and parse. I was apprehensive that some nuance of this passage of history would get shredded by some inane right- or left-wing outrage, and be denied an opportunity to make some meaningful impression on the minds of its viewers.

    I daresay that this is a legitimate concern at a time when writers and journalists have had to double-check how something might be construed on social media platforms, in specific parts of the country, even to a court somewhere. We may never be able to fully control how something that we produce will be consumed but there are parts of it that we can. In my own writing, I noticed last year a tendency to be defensive, to write in such a way that I explain myself thoroughly and accommodate all possible counter-arguments. The style is time-consuming and, more importantly, because how we write can affect how we think, it leads to defensive thinking as well.

    I was also anxious of encountering the hypocrisy that I suspected would be put on display when, despite being able to find physics beautifully described in hundreds of articles and videos on the web, the “average audience” recoils from them but gravitates with glee to Oppenheimer, and perhaps after holds forth on Facebook as if it understood the ideas involved all along.

    But then, in the film, Oppenheimer tells Leo Szilard that the scientists who made the bomb have no greater say than others about how to use it. I disagreed with the comment, but it struck me that we’d have to agree if we replaced “bomb” with “knowledge”. I’m glad that more people now know about the circumstances in which the first nuclear weapons were made because even if only a few are prepared to treat the film as a gateway, rather than as the definitive take or whatever, the world should be the better for it.

  • Irritating Google Docs is irritating

    The backdrop of the shenanigans of ChatGPT, Bard and other artificial intelligence (AI) systems these days has only served to accentuate how increasingly frustrating working with Google Docs is. I use Docs every day to write my articles and edit those that the freelancers I’m working with have filed. I don’t use tools like Grammarly but I do pay attention Docs’s blue and red underlines indicating grammatical and typographical aberrations, respectively. And what Docs chooses to underline either way is terribly inconsistent. I have written previously on how Docs ‘learns’ grammar, based on each user’s style, and expressed concern that its learning agent could be led astray by a large number of people, such as Indians, using English differently from the rest of the world and thus biasing it. Fortunately this issue doesn’t seem to have come to pass – but the agent has continued to be completely non-smart in a more fundamental way. This morning, I was editing an article about homeopathy on Docs and found that it couldn’t understand that “homeopathy”, “homeopathic”, and “Homeopathy” are just different forms of the same root word. As a result, correcting “homoeopathy” to “homeopathy” didn’t suffice; you have to correct each form to remove the additional ‘o’.

    It gets worse: the same word in bold is, according to Google Docs, a different word…

    … as is the word with a small ‘H’.

    Google has a reputation for having its fingers in too many pies and as a result neglecting improvements in one pie because it’s too busy focusing on another. There is also a large graveyard of Google products that have been killed off as a result. There’s some reason, for now, to believe Docs won’t meet the same fate but then again I don’t know how to explain the persistence of such an easily fixable problem.

  • NYT’s profile of India’s space startup scene

    The New York Times published a ‘profile’ of the Indian spaceflight startup scene on July 4. The article is typical in that: a) by virtue of being published by one of the world’s most-read news outlets, it can only be a big boost to the actors in its narrative, in this case a few Indian startups; and b) it takes a superficial outside-in view that flattens complex issues and misses finer points that, to local observers, would change the meanings of some sentences in important ways.

    By and large, the article seems like a swing in the opposite direction from that distasteful cartoon in 2014 – even if there is still that note of surprise, and that fixation on ISRO doing things at a lower cost, overlooking that it has not infrequently come at the expense of lower efficiency on many fronts. Then again, the article’s protagonists are the space startups, and I’m sincerely excited about their work.

    In this post, I want to point out one issue that I think The New York Times could have fixed before publishing: the word “heavy” has been used in a confusing way in the article even if it’s been used only twice. First (emphasis added):

    As ISRO … makes room for new private players, it shares with them a profitable legacy. Its spaceport, on the coastal island of Sriharikota, is near the Equator and suitable for launches into different orbital levels. The government agency’s “workhorse” rocket is one of the world’s most reliable for heavy loads. With a success rate of almost 95 percent, it has halved the cost of insurance for a satellite — making India one of the most competitive launch sites in the world.

    In the launch-vehicle sector, the word ‘heavy’ has a specific meaning and can’t be used directly in its colloquial sense. The “workhorse” referred to here is obviously the Polar Satellite Launch Vehicle (PSLV), which, like the Geosynchronous Satellite Launch Vehicle (GSLV), is classified as a medium-lift launch vehicle. ‘Medium-lift’ means being able to lift 2-20 tonnes to the low-earth orbit (LEO). This in turn implies that the article’s (first) use of “heavy” means just colloquially heavy. The second use creates the confusion (emphasis added):

    It was Elon Musk who stole India’s — and the world’s — thunder on the space business. His company, SpaceX, and its relaunchable rockets brought down the cost of sending heavy objects into orbit so much that India could not compete. Even today, from American spaceports at $6,500 per kilogram, SpaceX’s launches are the cheapest anywhere.

    One could think that since both the PSLV and SpaceX’s reusable launch vehicle, Falcon 9, lift “heavy” payloads, they have the same capacity, affirmed by the line that SpaceX stole India’s thunder. This is not true: Falcon 9 (in the Block 5 configuration currently in use) can lift 22.8 tonnes to the LEO and 8.3 tonnes to the higher geostationary transfer orbit; the PSLV can manage only 1.4 tonnes to the latter.

    A clarifying quote follows:

    “We are more like a cab,” Mr. Chandana [of Skyroot] said. His company charges higher rates for smaller-payload launches, whereas SpaceX “is more like a bus or a train, where they take all their passengers and put them in one destination,” he said.

    Given the masses involved, the PSLV was always a “cab” compared to the Falcon 9. In fact, ISRO is currently working on its own reusable launch vehicle with a payload capacity of around 20 tonnes to the LEO and an expected mass-to-orbit cost of $4,000/kg, down from around $20,000 today. This thing, whenever it is ready, will create an actual opportunity for thunder-stealing on either side (it has already been considerably delayed).


    There are many other niggles that, as I said, I won’t get into, but I must say that I’m very curious why “pharmaceuticals” has been singled out here, together with “information technology”:

    An image of India’s first satellite graced the two-rupee note until 1995. Then for a while India paid less attention to its space ambitions, with young researchers focused on more tangible developments in information technology and pharmaceuticals. Now India is not only the world’s most populous country but also its fastest-growing large economy and a thriving center of innovation.

    What is this secret revolution that I’ve missed, a revolution that, by implication, contributed to the country’s economic position today? Perhaps it’s generic drugs – but it pales in comparison to the growth of the IT sector and there has been no indication that it was led by “young researchers”. So, curious…

  • A request to ISRO about Chandrayaan 3

    The Indian Space Research Organisation (ISRO) has said its launch window for the Chandrayaan 3 mission is July 12-19. For now, the mission is expected to lift off on July 14 (at 2.35 pm IST). Chandrayaan 3’s mission is the same as that of its predecessor, Chandrayaan 2, with some marginal additions.

    It has the same hardware configuration, including a lander named ‘Vikram’ containing a rover named ‘Pragyan’, attached to a propulsion module. The surface lunar mission has a planned lifetime of 14 days. The lander has four scientific payloads and the rover, two. The propulsion module itself has one. The biggest difference between the two missions, it would seem, are changes to reduce the chances of another crash-landing. As Jatan Mehta wrote in his ‘Moon Monday’ newsletter:

    To increase the chances of sticking the landing this time around, ISRO has made several upgrades to the Chandrayaan-2-like lander, such as software improvements to accommodate failure, strengthened legs, a couple of new sensors for enhanced and redundant navigation-related measurements, and better power and communication systems.

    Chandrayaan 3’s success will strengthen India’s position within the Artemis Accords, which it signed just last month, because it will make the country one of only four to have landed and operated a rover on the Moon. But as much as ISRO has a good reason to aim for success, it may have an opportunity if the mission fails as well – an opportunity to show that it has matured as an organisation.

    The Chandrayaan 2 mission experienced a partial, but significant, failure on September 7, 2019, when its lander, bearing the rover, crashed on the lunar surface instead of gently touching down. ISRO researchers later traced the problem to a glitch in the onboard computer that lowered the amount by which the lander had to decelerate as it descended and an issue in the propulsion system. But a few months passed between the crash and the crash report, and in this time, the public conversation surrounding the accident was a cesspool of hyper-nationalist narratives and counterproductive statements by senior ISRO members.

    As soon as news of the lander’s crash became public, ISRO stopped communicating updates, and refused to admit – despite all the evidence pointing that way – it had happened for a full week. In keeping with the national BJP government’s mission until then to make the Indian space programme a matter of national pride by couching its feats in a nationalist narrative, social media platforms were inundated with claims from the usual corners that the part of the mission that had failed was a “technology demonstrator” that made up a minor part of Chandrayaan 2.

    Around this time, then ISRO chief K. Sivan also told journalists that the Chandrayaan 2 mission was a “98% success” – a stunningly disingenuous attempt to downplay what had been, until the mission’s launch, the basis of many of ISRO’s claims to greatness as well as which had occupied hundreds of scientists and engineers for several years. Technology demonstrators are important, but ‘Vikram’ and ‘Pragyan’ weren’t just that; more importantly, no way they were just 2% of the mission. Yet Sivan had been the one to say such a thing, even if he later palmed the blame off to a review committee, even as the organisation he helmed made Herculean efforts to reestablish contact with ‘Vikram’. All of this vitiated the narrative of the incident.

    To make matters worse, after the lander’s crash on the day, journalists gathered at the ISRO HQ in Bengaluru were treated to a scene as Pallava Bagla shouted demanding Sivan address them. When ISRO members other than Sivan did turn up, he was rude. Bagla later apologised for his behaviour – but not before a senior Congress leader, Abhishek Singhvi, called Bagla “insane” and asked for him to be sacked. It seemed for a time that no one was interested in letting the dust settle.

    For those who were plainly curious about the mission’s technical specifics as they existed, the specifics in which ISRO’s lessons for future missions, including Chandrayaan 3, would take root, the sole resource (in my limited experience) was the ISRO forum on Reddit, where independent spaceflight enthusiasts were putting together and combing through photos captured by NASA’s Lunar Reconnaissance Orbiter to find the lander’s resting place and clues to the cause of the accident.

    The Indian government has a penchant for cutting access to information after major accidents and disasters. It did so after the Joshimath landslip, when ISRO reported that the town had slid by 5.4 cm in 12 days. It did so after it supposedly liberated Jammu and Kashmir by abrogating Article 370 of the Constitution. It did so after the Manipur riots and is yet to restore connections in the state, going so far as to brook long-winded arguments about access to VPNs in the process.

    Even before Chandrayaan 2, there were some signs that ISRO had become part of the fold, including – but not limited to – the BJP government’s narratives of ISRO’s feats, the organisation’s increasing opacity, and pettiness in the face of criticism. In 2018, its then chief Sivan said that ISRO would like to lead international efforts to mine helium-3 on the Moon and transport it to the earth, disregarding the unhelpful hype and pseudoscience surrounding the isotope’s potential as a nuclear fuel.

    More recently, Sivan’s successor and current chief S. Somanath claimed that India has had a “knowledge society” since “Vedic times”, that Indians’ accomplishments were appropriated by Western scholars who then regurgitated it as their own findings, and that “those working in the fields of artificial intelligence [and] machine learning love Sanskrit”.

    These signs aren’t encouraging, but it’s possible to hope that these individuals and their advisors will put ISRO above themselves and their opinions. I sincerely wish that Chandrayaan 3 succeeds to the tune of 100%. At the same time, space is hard, as they say (especially for less-well-funded and less-well-technologically supplied organisations like ISRO).

    And in the event of a failure, I hope ISRO will respond by sharing regular and timely updates, answer journalists’ queries, think before speaking, and, overall, conduct itself with the grace of being the premier space-faring body of the Global South.
