The Nobel prize in mathematics

There was an interesting article in Der Spiegel about Angela Merkel’s visit to a Berlin secondary school as part of the the “EU-Projekttag”, a national day for teaching about the EU and its institutions. (No surprise that nothing like this happens in Britain.) This school has mostly Muslim immigrant children, and she found that instead of asking about the functions of the European Parliament the children wanted to tell her about discrimination in Germany.

Fatma, eine 15-jährige Jugendliche mit Kopftuch, klagt über Schwierigkeiten beim Praktikum im Kindergarten, weil die Eltern keine Erzieherinnen mit Kopftuch wollen. Das habe ihr Chef ihr gesagt. Ja ja, sagt Merkel, die inmitten der Schüler auf der Bühne Platz genommen hat, man kenne das Problem von Bewerbungen junger Menschen mit komplizierten, ausländisch klingenden Namen. “Viele glauben da nicht, dass jetzt gleich ein Nobelpreisträger in Mathematik um die Ecke kommt.”

[Fatma, a 15-year-old with head-scarf, complains about her difficulties in an internship in a kindergarten, because the parents don’t want a teacher with head-scarf. Her boss told her that. Yes, yes, says Merkel, who is sitting on the podium with the students, we know these problems, as with job applications from young people with complicated, foreign-sounding names. “Many people don’t think, this is a future Nobel-prize winner in mathematics coming around the corner.”]

Never mind this bizarre and nearly incomprehensible stream-of-consciousness from a major world leader asked an uncomfortable question by a 15-year-old. What is it about the chimeric Nobel prize in mathematics? Alfred Nobel established prizes in subjects that were related to the kind of practical science that he made his fortune with (chemistry and physics) and to the kind of selfless causes (medicine, literature, peace) that he hoped would blur the association of his name with weapons manufacture. There are lots of subjects that he did not create prizes in. Mathematics. Geology. Engineering. Astronomy. History. Cooking. No one thinks it odd that any of these subjects don’t have a Nobel prize, except mathematics. They think it so odd, that they either imagine that there actually is one, as above, or they invent outlandish stories to explain this lacuna, generally involving some mathematician — Gosta Magnus Mittag-Leffler, when he is given a name — running off with Nobel’s wife. (This story has the advantage of Mittag-Leffler actually having been Swedish, but the fact that Nobel never married is usually counted against its credibility.)

Risk categories and e-cigarettes

I’ve been reading Kate Fox’s celebrated Watching the English, which is sort of a pop-sociological treatise on English customs, but somewhat hard to take for all its flattering the English in all the myths they cherish about themselves — including their supposed modesty and inability to accept compliments. (I was particularly astonished by her description of the supposedly considerate English drivers. Perhaps they treat other drivers with more respect than they can spare for pedestrians.)

Anyway, since I am intrigued by the way “e-cigarettes” — devices for inhaling an addictive drug — have managed to float free from drug regulations, not to mention the prohibition that usually gets slapped onto designer drugs, as well as from their association with increasingly illicit tobacco. Fox is a huge fan, and can’t understand how anyone could object:

These clever devices are a sort of glorified version of nicotine inhalators, which look and feel rather more like a real cigarette, and emit a totally harmless, odourless steam or vapour that looks a bit like smoke. Many people are now accustomed to seeing these electronic cigarettes, and know that they are harmless…

Some people, however, do not instantly grasp this… and I have been conducting informal cross-cultural research on their reactions. In England, there are the usual raised eyebrows, frowns, pursed lips, tuts and mutters… But in all the years that I have been using these e-cigarettes on public transport and in restaurants, pubs and other public places where smoking is banned, only one English person has ever actually ‘confronted’ me about it…

In almost all countries, this disapproval quickly turns to friendly laughter, or curiosity, once I have explained that my ‘cigarette’ is an innocuous electronic device. The only exception I have found so far is the US, where some people seem to object almost as much to completely risk-free e-cigs as they do to the real thing — an irrational reaction that brings to mind my favourite definition of Puritanism: ‘The haunting fear that someone, somewhere, may be having fun.’

(Mencken’s definition was actually “that someone, somewhere, may be happy”.) There’s a fascinating number of words about risk here: odourless, harmless [twice], innocuous, completely risk-free, irrational reaction. It brings to my mind the ridicule heaped upon the killjoys who suggested in the 1980s and 1990s that something as innocuous as sidestream tobacco smoke could harm people’s health. Now everyone accepts that sidestream smoke is highly toxic, but the completely unregulated mixtures of chemicals spewed out by e-cigarettes are supposed to be harmless. On the basis of advertising copy, so far as I can see.

In contrast to the anthropologist Kate Fox, mere epidemiologists do not describe the second-hand exposure to e-cigarette vapour as “completely risk-free”. Instead, they say things like

Schober et al. measured indoor pollution from 3 people using e-cigarettes over a 2-hour period in a realistic environment modeled on a café. They found elevated nicotine, 1,2-propanediol, glycerin, aluminum, and 7 polycyclic aromatic hydrocarbons classified as probable carcinogens by the International Agency for Research on Cancer in the room air.[…]

on average, bystanders would be exposed to nicotine but at levels 1/10th that of cigarette smoke (e-cigarette aerosol, 3.32±2.49 μg/m3; cigarette smoke, 31.60±6.91 μg/m3; P=0.008). Both e-cigarette aerosol and cigarette smoke contained fine particles …

So e-cigarette vapour contains known carcinogens and the addictive drug nicotine. It is known that persistent low-level exposure to nicotine can provoke nicotine dependence, particularly in adolescents, or predispose them to other drug addiction.

Some people choose to take that drug recreationally, and I don’t object to them having that right. But why would a scientist disparage other people’s unwillingness to accept these risks to support her habit as “an irrational reaction”?

Of course, I know why. It’s one of the standard clichés about scientists, that they use the pose of rationality to claim an authority that they have not earned, to pretend that their private caprices are facts. It is unprofessional, and it undermines the whole enterprise of science.

A real champion of academic freedom

I’ve commented before about the craven assault on academic freedom at the University of Southampton, which feigned concerns about “health and safety” to justify cancelling an uncomfortable conference on international law and the legitimacy of the state of Israel. But for me it’s mainly an abstract issue. I’m not involved in the conference, my political views lie messily between those of the conference organisers and their opponents, and it’s not a hugely important topic to me.

One name that I noticed, with interest, on the programme, was that of Geoffrey Alderman, professor of history at University of Buckingham. I know of him from his frequent contributions to the Jewish Chronicle, which I usually filed in the “staunch Zionist” column, with some of the blindspots typical of that worldview. I was impressed with his willingness to appear in such a forum, clearly slanted against his beliefs, both because of the discomfort that entails, and because of the danger that his ideological allies would see him as a traitor to the cause.

He has now written a letter to Times Higher Education, forthrightly condemning this triumph of obscurantism.

As a proud Jew and a proud Zionist, I am appalled. As a patron of the Council for Academic Freedom and Academic Standards, I am outraged. As someone who was to have presented a paper at the conference, I am horrified.

Academic freedom is indivisible. There is no subject that cannot be discussed in a university environment.

As a proud non-Zionist Jew, I am hugely impressed, and encouraged.

Truth and typeface

In an article about a performance by Allen Ginsberg 50 years ago in the Albert Hall, we read

Ms Leavey, who has listened to a recording of the event made by the BBC but never used in its entirety, said that Ginsberg faced a torrent of heckles, the clearest of which was a reference to an earlier recital by Christopher Logue, who had been on stage performing translations of Sophocles.

One wonders who was the author of Sophocles, and which language it was translated from.
Interestingly, I note that the online version does not put Sophocles in italics. It’s an interesting example of where typeface, like punctuation, can make hash of an otherwise accurate statement.

The biggest genetics-investment opportunity ever!

I was just looking at this paper from 2012, that purports to discover the heritability of economic and political preferences by slightly shady statistical analysis of GWAS data. And then it hit me: We could market

An investment plan tailored to YOUR genotype

Okay, we’ll have to work on the catchphrase. Feel free to send your seed money. (The genotype-based diet is running like gangbusters.) Excuse me while I go off for a moment to write the patent application.

Impact!

A new challenge for computer science

Do you remember the Sokal affair? Mathematical physicist Alan Sokal submitted a fake paper titled “Transgressing the Boundaries: Towards a Transformative Hermeneutics of Quantum Gravity” to a postmodern cultural studies journal Social Text. Well, it was a real paper, but it was a hoax. It was written as a hoax, cobbling together the silliest tropes he could find about social construction of science and left-wing politics. Once it was published, he used it as a club to beat up on postmodern theory, and the humanities more generally. Many self-satisfied scientists claimed, at the time, that this confirmed all their worst suspicions about the emptiness of academic jargon-spinning in the humanities and social-scientists. The implication — sometimes made explicit — was that the reverse could never happen, that scientists know exactly what their terms mean, and could never be fooled by such a prank.

It turns out, the situation is much worse than that. Springer and IEEE have been forced to withdraw 120 papers that they published in various conference proceedings, and that turn out to have been randomly generated by the software SCIgen. Concerned to assure the public of the reliability of their peer-review process, Springer has now announced a technical solution: SciDetect, software that checks papers to determine whether they have been generated by SCIgen. (If it had been announced today I would have assumed that it was an April Fools prank, but the press release is from 23 March.)

Confirming me in my opinion that the whole system of peer review has outlived its usefulness, and is now living on as a vestigial parasite on the scientific enterprise.

Anyway, Springer has now thrown down the gauntlet, and young computer scientists should rise to the challenge of improving SCIgen, to fool the new software. We may see an accelerating arms race in scientific publishing, a kind of reverse Turing Test, with computers trying to fool other computers into believing that they are computer scientists. In the end, maybe the software will get so good that it will be doing original research and writing real scientific papers.

Heckler’s veto in Southampton

A couple of weeks ago I signed a petition in support of a conference planned for 17-19 April at the University of Southampton, on “International Law and the State of Israel: Legitimacy, Responsibility and Exceptionalism” that had been threatened with cancellation because of pressure from the Board of Deputies of British Jews and the UK Zionist Federation; ubiquitous-parking enthusiast and Communities minister Eric Pickles also contributed his opinion. It seemed to me an obviously legitimate academic conference, on a subject of both academic and public interest. If the choice of speakers does not cover all possible opinions on the matter — my impression is that my own view would not really coincide with any of those represented, and the framing of the topic is too politically tendentious for my taste — well, that’s unfortunate, though I’d wait until after they’d spoken to comment on what they have to say, and then opponents are free to organise their own conference.

Now the university has decided to cancel the conference because of specious “health and safety” concerns: because protestors threatened violence, or because the university authorities consider them the protestors — or the conference organisers — inherently deranged. I recognised long ago that “health and safety” is the leading weasel word in the British bureaucratic vocabulary. Pretty much anything can be justified with it, and it sounds so much more decisive and incontrovertible than saying “I am worried that someone could get hurt” (or “someone could catch Ebola”).

This is a dangerous decision. As someone whose grandparents’ generation was forced out and/or murdered by brownshirt thugs who came to power in Germany and then most of Europe after applying the strategy of directed violence against opposing political and intellectual viewpoints, I am dismayed to see that Jewish organisations in the US (see, e.g., the Salaita affair) and UK have come to the conclusion that the main problem with the Third Reich was too much free speech. Never again!

This is a dangerous step. Either Southampton will make itself a pariah by this move, or it will make itself an example to other universities, who increasingly find that all that academic exchange-of-ideas mumbledy-goop just gets in the way of the free exchange of money and services with well-connected donors.

Prenatal sex ratio

A paper that I’ve been involved with for a dozen years already has finally been published. We bring together multiple data sets to show that the primary sex ratio — the ratio of boys to girls conceived — is 1, or very close to 1. Consequently, the fact that more boys than girls are born — the ratio is about 1.06 pretty universally, except where selective abortion is involved — implies that there must be a period in the first trimester when female embryos are more likely to miscarry than male.

This is one of those things that is unsurprising if you’re not an expert. The experts had developed something close to a consensus, based on very little evidence, that the sex ratio at conception was much higher, some saying it’s has high as 2 (so that 2/3 of the conceptuses would be male), with excess female mortality throughout gestation. (We know that male mortality is higher in the second half of pregnancy, and after that… forever.)

The paper has its problems, but I think it’s a useful contribution. It’s also the first time I’ve been involved in research that is of any interest to the general public. Several publications have expressed interest, and an article has already appeared in two German magazines online, including the general news magazine Der Spiegel.

Update: Guardian too. This makes it interesting, in retrospect, that we had such a hard time getting a journal even to be willing to review it. One said it was too specialised.

The Pope’s Shluchim

I’ve just been reading Amir Alexander’s book Infinitesimal, about the intellectual struggle over the concepts of infinitesimals and the continuum in mathematics and science (and theology) in the 17th century. The early part of the book is a history of the Society of Jesus, presented as a ruthless and intellectually daring force for religious conservatism, strictly hierarchical, devoted to its holy founder, a thoroughly mystical movement that built its reputation and influence on educational outreach. And then it struck me: The Jesuits were just like Chabad-Lubavitch!

The patron saint of cranks and charlatans

I can’t remember who it was who referred to Galileo that way. Ted Cruz, the right-wing US senator, presidential candidate, and one-time Ivy League super-elitist has invoked the protection of this saint to defend his position on climate change, in opposition to the overwhelming consensus of the experts:

Today the global warming alarmists are the equivalent of the flat-earthers. You know it used to be: ‘It is accepted scientific wisdom the Earth is flat.’ And this heretic named Galileo was branded a denier.

This is standard crank-Galileo stuff, impressive for the number of misconceptions it builds into such a small space. Of course, Galileo’s critics didn’t think the Earth is flat. It was certainly not “accepted scientific wisdom” in his day. (Beyond any theoretical or cultural understanding, it was nearly a century since Portuguese sailors had circumnavigated the globe.) Galileo was not dismissed by the scientific experts of his day. His theories and discoveries were controversial, but he was generally acclaimed by scientific authorities. He was punished for contradicting the Church’s entrenched philosophical commitments, by a panel that, while not completely devoid of expertise in astronomy and Aristotelian physics, was chosen for its institutional commitment to the Church. It’s not really the most felicitous comparison for a climate-change denier to bring up.

Logical fallacies aside — “They laughed at the Wright brothers. They also laughed at the Marx brothers.” — there aren’t many cases of new ideas being dismissed as ridiculous by the scientific community, and later proved right. There is often entrenched conservative resistance (as there should be) to radical new ideas, but almost never is a single thinker so far beyond everyone else that his ideas don’t elicit significant support. Perhaps the best exception is Alfred Wegener, with his obviously crackpot theory of continental drift. For some reason Galileo, who was very much respected and mainstream, gets called into service to defend the crazies, and not Wegener. I imagine that Cruz’s backers would be almost as uncomfortable with plate tectonics as they are with evolution, if they knew anything about it. At that point the USGS would be banned from using plate tectonics to predict earthquakes.

In any case, Wegener wasn’t sitting in a Senate office reading Heritage Foundation talking points; he learned everything that was known about geophysics (which wasn’t much at the time) conducting expeditions to Greenland to collect evidence.
