thraway180306··on The reanimation of pseudoscience in machine learning
For context, you have a consulting business, and spoke at a conference about AI in administering justice organized under auspices of recently ousted illiberal government of Poland.

Here's an abstract to one of your "papers": "The paper presents selected tools, as described by their developers. The list includes Hello Quantum, Hello Qiskit, Particle in a Box, Psi and Delta, QPlayLearn, Virtual Lab by Quantum Flytrap, Quantum Odyssey..."

Et patati et patata - no way to tell what you're about with your review other than enumeration and platitudes. Yet you criticize authors of a review paper (detail revealed by immediate next sentence, one you curiously decided to omit from quoting) that clearly state their angle first and at least have something to say. It's just not aligned with your opinions, nothing to do with writing.

You by the way demand "results" of a review paper. What were the research results of you playing quantum web games?

thraway180306··on New cryptocurrency could potentially cause an SSD or hard drive shortage
Yeah, wow, whitepaper expects their reserve matched by other farmers only after 21 years of Chia mining/plotting.

I see Bram Cohen got the original authors of "proof of space" or whatever this is to author papers with him, and also got inflationary pressure in there, but if that's the extent of research, well, that's still not how the economy works. At least ransomware gangs won't switch from encrypting to deleting stuff altogether for space.

thraway180306··on Eye-catching advances in some AI fields are not real
The whole point of Bousquet study was comparability, so it had to be the lowest common denominator, especially in a field that defines SotA differently year to year in each wave of research. Your objection wouldn't embarrass anyone.
thraway180306··on Eye-catching advances in some AI fields are not real
You are complaining how the article doesn't mention GANs while replying to a comment about article's treatment of GANs. Revealing you are biased against even reading the biased article, or comprehending the parent comment.
thraway180306··on The strange postulated link between the human mind and quantum physics (2017)
That's a significant goalpost move. From debating particular mechanisms and postulated inevitability of AI, to assuming full blown strong Church-Turing-Deutsch principle and moving from there. Along with moving whole discussion from practical concerns into philosophy and really arguing from the thesis, at which point most people lose interest.
thraway180306··on The strange postulated link between the human mind and quantum physics (2017)
All chemistry is ultimately quantum, same with rocks and everything up to celestial bodies (meaningfully, the moon Hyperion decoheres). For most of calculations though classical models are good enough, vast majority of chemical reactions behave as if molecules were newtonian springs. When people talk of quantum effects in chemistry they really mean it. In case of photosynthesis the basic molecule's efficiency was found hinging on stuff that is very quantum. This was described by Gregory Engel et al. Alan Aspuru-Guzik interprets some of what's happening as a realization of quantum computation running a tree-walking algorithm.

The wider conclusion is that living organisms do evolve around quantum effects (if the molecule existed a priori somehow) or maybe even evolve to the point of reaching and then harnessing them (making the molecule).

Now to what's Penrose about. Seldom anybody actually reads the guy or know the context. He was after the computational theory of mind. Not necessarily looking for a theory, but sneering at one big non-theory. This is in context of the 80's with unhinged stuff coming from the AI community (same as today). He was wondering if brain could really be this reducible and a known model of computation (he hasn't done a good review) from the physical point of view. For him a full logical reductionism necessiated excissing the measurement problem (the basic point goes back to Niels Bohr who thought biology cannot be entirely physics because of this). So he proposed a crude version that fleshes out measurement as a real physical process. His idea has the main upside of removing both quantum and AI mysticism.

This received angry and mostly off-topic response based on caricature summaries like elsewhere in this thread. Of course lending themselves to such caricatures says a lot about writing if not the ideas, but it's an honest try that ain't entirely silly and without upsides. The microtubules guy is someone else who Penrose was just happy to see come and collaborate with later. He'd be happy with any kind of other stuff, such as from the original article. BTW the author is Philip Ball, a long time editor of the Nature journals, and he's got a new book out about interpretations of quantum mechanics that is really superb to anything else on the market by far (that is could be better but isn't worthless).

thraway180306··on Academic Activists Send a Published Paper Down the Memory Hole
I find these threats doubtful, I don't see the editorial board wasting their life on sustained activism over the years chasing remnants of something they helped to create and what would be served a deathly blow by their resignation already. The author however has a history of activism I haven't looked into, but that usually involves a spin. There's also the possibility of his correspondents' misguided politeness by throwing him something to chew on to diffuse the blame. Mathematical Intelligencer editor could be seen as doing that in a somewhat more intelligent way blaming the possibility of "international hype".

As for the description of alleged emotional states involved, I'm oblivious and not seeing the relevance. Recounting the events and actions taken sufficed for a horrific story. The author deemed it important however to make it into something even more colourful with threats of some unspecified future actions (how does one harass a journal?).

The managing editor you speak of went on leave and has an interim replacement. I can see that entirely appropriate if only because of how retraction was handled by deletion and overwriting, instead of a proper notice in place. This was extremely unprofessional administration, which is usually a duty of the managing editor solely. The other possibility I described is that it wasn't really published the usual way, which is even more damning.

thraway180306··on Academic Activists Send a Published Paper Down the Memory Hole
The process, as told by the author, was that one of the editors invited to submit, and three weeks later it was published upon which the rest of the editorial board took notice and threatened resignation.

By that telling it was published practically on the spot, especially for mathematics where things are famously glacially slow. Browsing through the journal one mostly sees submission and publication dates separated by many months. Last published paper in the current volume was received over a year before. But this paper made it in three weeks.

So it was fast tracked by an editor. Editorial board could take issue with that, arguing it haven't gone by the review properly or whatever the usual procedures before publication are. It might have been put up on the web by the managing editor (since on leave and replaced in the interim) or whomever had the admin password, but editorial board to whom the journal's reputation really belongs hasn't deemed it to be their publication.

Of the timeline, author says he's uploaded to ArXiv in September, while by that time he was on revision 3 of https://arxiv.org/abs/1703.04184 uploaded in March. What was added in September however was a piece of journalism in an appendix, that then disappeared in most recent revisions. Last revision was posted just 2 weeks ago, apparently there still were arguments to strengthen (or journalism to remove) before Quillette ran the story.

There he paints his work as "science" and some people including the editorial board as "activists". By Google however appears the same Ted Hill founded a site "to promote campus activism in general" and "to serve as a focal point for organizing activists" where he chronicles his long history of activism http://www.motherfunctor.org/CompleteHistory2013.php

thraway180306··on Academic Activists Send a Published Paper Down the Memory Hole
Sorry, but the ArXiv does have a moderation team and stuff is being removed. Alike, most online journals remove stuff by wholly replacing it with a retraction notice. Journals printed on paper issue retraction letters and leave it at that, but some also do restrict online access afterwards.

What no journal does is to replace erroneously published article with another entirely unrelated one in-place. This is a very poor behaviour on the part of the managing editor here, who is currently on leave and replaced.

Nature is unusual, for example they publish letters complaining about ArXiv's moderation, beside publishing a lot of editorial and opinion stuff.

thraway180306··on Academic Activists Send a Published Paper Down the Memory Hole
Sorry, but it is for everybody to decide. Reviewers don't have a sacred sanction and exclusive right to judge. Many a time in cases of plagiarism I worked through I've met with this argument from the accused authors. It boils down to that I have no right to question basic decency because only reviewers are entitled to pass judgement on that and they already did.

Also from the description, which is not impartial being by the author, it is admitted it was snuck into an online journal by one of its editors. We don't know anything about the nature of peer review in this case other than when the wider board of editors got a know of that, majority of them allegedly threatened to resign.

It is however a very bad form by the managing editor to publish another article in the place of the other, even if that one was decided to be published erroneously. NYJM journal page says he's on leave and ceded his duties to an interim replacement.

thraway180306··on Academic Activists Send a Published Paper Down the Memory Hole
What the parent charitably didn't stress is that this proof is the totality of mathematical work in this paper.

The rest is a stream of words.

As such it is a work of social science. It might even have been respectable in social science journal. Economists input a lot of assumptions into calculus 101 level equations and call that a "mathematical proof" of an economic theory.

If the author wanted this to be a interdisciplinary discussion, why drag it into a mathematical journal where actual mathematical truths are published?

Author says himself he was unable to formulate actual mathematical idea and recruited help. Why ask Tabachnikov, who is a geometer specializing in classical mechanics, instead of someone with like a clue about statistical modeling? He then compares his experience to one he had fighting in Vietnam... which only makes me wonder if that wasn't the point: to either succeed with a flag-planting diversion or be able to make that comparison and hero of himself anyways.

thraway180306··on A visualization of the prime factors of the first million integers
It captures more of the spatial (metric topological) arrangement in the set. Example they give in the paper is the MINST dataset where distinctly looking digits like 1 and 0 get separated farther apart and similar ones clump together, whereas t-SNE while correctly delimiting individual clusters clumps them all in a blob.
thraway180306··on A visualization of the prime factors of the first million integers
Without (arbitrary) scaling normalization PCA gives different results with change of dimensional units, that is principal components depend on choice of units or scaling.
thraway180306··on A visualization of the prime factors of the first million integers
structure to the space of prime factors

There is topological structure https://math.stackexchange.com/questions/2879/mapping-natura... http://ncatlab.org/nlab/show/arithmetic+topology as well as geometric (arithmetic geometry). Question is how does the picture correspond to any of it. Glancing at the UMAP paper https://arxiv.org/abs/1802.03426 it looks like a proper invariant preserving embedding, so maybe loops in the image are real. Even if not, it does hint artistically at sorts of stuff that exist.

thraway180306··on A visualization of the prime factors of the first million integers
PCA is dimensionally invalid, it destroys, not preserves structure and consists of arbitrary linear algebra operations. It is "less arbitrary" the way x86 assembly is "less arbitrary" wrt. C (actually it ties you to a certain mode of thinking).
thraway180306··on Do electrons think? (1949)
Not true, a lot of mathematical problems behave better (but other semiclassical approaches also exist).

As for the epicycles comparison, it's actually apt. They could have given complex plane and Fourier analysis for free if they had a chance (not to mention Copernicus actually used more of them than Ptolemy)(which incidentally is also the case with Many-World-necessiated landscapes and parameter spaces - just as much additional layer but with additional problems that are, in contrast, untractable by current math).

thraway180306··on Do electrons think? (1949)
This is something different. Zeilinger paints himself disproving realism alone and has a well known philosophical stance/bias here. Local realism testing here however is about being both local and realist, and pilot waves aren't local to begin with.
thraway180306··on Do electrons think? (1949)
Relativistic extensions aren't pleasant in standard QM either.

Bohmian formalism would require something perhaps no less aesthetically repulsive, but surely more alien: a preferred foliation of spacetime to avoid a preferred reference frame. Turns out it wouldn't have to be an artificial choice, as it can be derived from the wave function itself https://arxiv.org/abs/1307.1714 (that would also mean this preference existing within QM irrespective of any interpretation).

thraway180306··on Do electrons think? (1949)
It would help if these weren't all from the same single source: Zeilinger's Vienna group and friends.

On the other hand formalism works seamlessly mathematically, which cannot be said of standard quantum mechanics. Even this year's Fields medalist Figalli has a paper on how good things are in Bohmian land.

thraway180306··on 2018 Fields Medal and Nevanlinna Prize Winners
It is in fact age limited precisely to combat ageism of the early 20th century. Otherwise only elders would get it (would they outlive the queue of their masters), when it's irrelevant to their career development (but beneficial to the prize's prestige). It was intentionally set up with this reasoning - not to be about lifetime contribution (which really compounds linearly in mathematics, there is no age dropoff "in the data" if you will) but making career easier for a very few young upstarts.

Otherwise it would be old people game.

thraway180306··on Welcome to the New Space Age
I made the joke on you.
thraway180306··on Welcome to the New Space Age
I just hate people

Wow, that's rich.

After some decades I discovered that physics too is about people. Social aspect is inescapable. That didn't turn me off, but taught to appreciate the narrative aspect as integral and thus maybe a part of the beauty. Not necessarily in the watered down journalism (which is fine, as a scientist I'm not the target audience) but the fact that the big narratives that harnessed collective resources previously were just that: big narratives. That was one of the functions and enablers of the Space Program itself, not sustained nor repeated since, to the determent of our capability. And that's what bystanders look for in science. (Not just them, if your social status and self-esteem hinges on you being a scientist, that's also taking part in narrative that enables you to thrive despite hating people).

If you really just hate people, then take example in Teller - he also knew the power of storytelling but just used it mercilessly.

thraway180306··on Gene discovery from a genome-wide association study of educational attainment
That's as much as Turkheimer's three laws of behavioural genetics are saying.

Contrary to how this field styles itself it is a quantitative social science having little to do with actual genetics, using next to none of its methods but a lot of quantitative social science's statistics with levels of signal similar to social science.

thraway180306··on Gene discovery from a genome-wide association study of educational attainment
May that be because this isn't field of genetics at all, but unrelated one called "behavioural genetics" (using quantitative methods of the social sciences, with similar levels of signal, and none of the certainty of actual genetics) wherein Turkheimer formulated the so called "three laws" not unaligned with GP's point?
thraway180306··on British cave diver considering legal action after 'pedo' attack by Elon Musk
But I see that frequently. There was all the kerfuffle around head of Tesla Autopilot quitting over Musk behaviour that also descended to namecalling. That painter guy who took issue with Musk stealing his artwork that ended up the same. That earnings conference call which felt like it could go there. Not on Twitter there are lots of stories of management by yelling.
thraway180306··on Things That Happen in Silicon Valley and Also the Soviet Union
Aggregate statistics for the EU is pretty much the same as for any single member state. You don't get any more complicated history than that, also half bigger than US. I don't see how you're so exceptional an orange. But then I don't roll my eyes as a proxy for thinking.
thraway180306··on EU copyright law proposal rejected
But I see no mention of lists, much less preventive lists. Yup, this is one of the possible mechanisms, but nowhere do I see it mandated as THE mechanism. For me it's business as usual just that now I fingerprint all files and maybe have a cron job for reuploads. I don't even see myself having to be accurate, just take care. I'm liable if negligent.

The most unfortunate thing I find about this is that's just a broad directive for each of the member states to implement its own way. But that's a general argument about every EU regulation.

thraway180306··on EU copyright law proposal rejected
Thank you for this very good summary. This is the most factual recount I've seen in numerous HN threads to date (which have been quite unhinged frankly). However I don't see how this forces content filtering. Service provider has to take responsibility for served content by having a process to help the complainant in the cleanup in contrast to just hiding behind users with a token “sorry for that, we'll now allow you to play hide and seek with them, sorry again”. Apart from shifting that burden, which I find reasonable, I see no difference to current mechanisms.

In particular I see no preventing publication, and the rightholder has to actively take part to indicate/identify the matter.

Beisde, the most recent text I see http://www.europarl.europa.eu/sides/getDoc.do?type=REPORT&mo... is a wasteland. Articles 13a, 13b and 13c popped up into existence, article 13 got itself a point -1 (that's a minus one). No wonder the Parliament requested further work. Which is what it did contrary to misleading reporting of rejecting anything (in particular any of the articles specifically).

Also, the text functions in a whole context of European law and reuses lots of notions. For example who is a commercial service provider seems to be lifted directly from a law being in force since the year 2000.

Most European law is peppered with calls to scale and proportion you take issue with, and yet they exist and live on with little problem.

thraway180306··on Eric Weinstein on the crisis of late capitalism
Now I have to read more of Weinstein's writings

Start with the one on how currencies and stocks behave like elementary particles in gauge fields. I stopped there, it was not just bad thinking, but torturous and clumsy twisting of physics bordering on crackpottery, just to jump on the bandwagon while the mainstream economics suffered acute physics envy. Now that mainstream narrative has changed he suddenly discovers philosophical issues and himself an inner philosopher.

I find it disgraceful that as per the linked bio "He delivered the Special Simonyi Lectures at Oxford University in 2013 putting forth a theory he termed “Geometric Unity” to unify the twin geometries (Riemannian and Ehresmannian) thought to ground the two most fundamental physical theories". These are outreach lecutres to lay public. To my knowledge "twin geometries" aren't "thought to ground" anything by anyone else than Eric Weinstein so that's misleading at best. Especially that he apparently didn't bother to write up what he means, even clumsily, much less to publish.

In fact he didn't publish anything in a physics venue ever at all. MathSciNet indexing math journals also returns zilch.

thraway180306··on The Universe Is Not a Simulation, but We Can Now Simulate It
Falsification is a philosophical issue. Some say it's important. Some could live without. See Feyerabend.

None of that matter if there is no theory in the first place. Much was tried. 't Hooft got as far as holographic principle. And there's still no theory at all.
