Of course, it is true that his books are unavailable on Amazon and Amazon-owned sites. I wish I knew what caused this, or how to find out.
I know people who, when considering faculty job offers from universities, use "are libraries open to the public" as a proxy for other valuable properties of the university. It seems like a pretty good heuristic to me.
I've been asked for ID exactly once on a university campus---I needed security to let me into my office building in the middle of the night because I'd forgotten my wallet in there, and they needed to record my name for some record. The officer didn't seem interested in _checking_ the ID so much as copying down the name.
The problem, of course, it that the timing doesn't make sense at all. You say this happened in the early 50's. That can't be the early 1850's, since Bader wasn't born yet. But by the 1950s, Feynman was already long gone from high school. Indeed, he'd already devised path integrals, and so he certainly knew about the principle of least action!
Perhaps you meant 30's?
A reasonable survey to send around might be "how often do you use the FreeBSD docs?" "How often do you notice errors in section 1? Section 2? Section 3?" That's not what this is. It's "here's a specific error, and I'm gonna run a /poll/ to figure out what the priority on fixing it is".
Even ignoring the "that's why we hired /you/" component---this must be a singularly ineffective way to gain reliable information. Very few people are going to reply (because each of the ~100 questions is rather technical!). The responses are therefore going to be self-selected to... I don't know, whoever has the time and will to waste on this.
In any case, here's the follow-up with the winners: https://scottaaronson.blog/?p=42
Really, this is a transparent attempt to bring that topic into unrelated threads. Let the namecheap-bashing stay in the namecheap-bashing threads.
I mean, we don't live in a representative democracy. Not in the sense you're describing.
(Assuming you, like me, live in the U.S.) Civil servants are not elected, are not directly accountable to elected officials, and are certainly not drawn from a representative cross section of the public. You may feel like they represent you, but that is (to be frank) little more than an expression of your own place in society. Civil servants form a discrete and powerful class, with their own interests, unions, and lobbying groups. Ignoring this is, optimistically, naive.
Surely this is several typos? Longitude, which marks east-west, must span 360 degrees (-180 to 180, perhaps? although 0 to 360 is just as reasonable). Latitude, marking north-south, spans only 180 degrees, and therefore is presumably -90 to 90 (so that 0 is the equator).
The article really has a strong vibe of "algorithms are faulty, we need humans in the loop to make sure they're behaving well!", with a hidden assumption of "humans are less faulty than algorithms". That's an empirical assertion to be determined on a domain-by-domain basis. It's certainly true that having a human in the loop leads to worse outcomes in chess (unless the human has enough modesty to just not do anything). The same is increasingly true of other domains as well.
Perhaps someday, incorrect, largely content-free FUD articles about how algorithms suck will themselves be written entirely by algorithms.
This is pushing way too many of my buttons, so I'll just close by pointing out (on the other side of the apps/humans scale) that a substantial fraction of the time, when I check the weather on NWS, it says something like "Today's high: 56; current temperature: 58". I certainly hope that a human in the loop would fix that problem.
There were and are taboos around loans in many societies (our own included). This seems like it's probably part of a broader family of methods for working around those taboos.
I came across this only from a side remark in Yukichi Fukuzawa's autobiography. I don't know of a good source (the wikipedia article is admittedly not great).
> Editors’ note, [30] March 2020: We are aware that this article is being used as the basis for unverified theories that the novel coronavirus causing COVID-19 was engineered. There is no evidence that this is true; scientists believe that an animal is the most likely source of the coronavirus.
And from "The Scientist":
> Update (March 11, 2020): On social media and news outlets, a theory has circulated that the coronavirus at the root of the COVID-19 outbreak originated in a research lab. Scientists say there is no evidence that the SARS-CoV-2 virus escaped from a lab.
And an obligatory link to SA's recent post on the phrase "no evidence": https://astralcodexten.substack.com/p/the-phrase-no-evidence...
> Prior to the outages, citizens had for months only been given a few hours of electricity per day
and I thought the fuel shortages were a recent phenomenon.
Regardless: does anyone have a link to a decent primer on what's going on (regarding supply chains, fuel, and all the other recent economic disruptions)? I'm not interested in the usual politically motivated "just so" stories, just a list of what's happening, what parts are definitely understood, and what parts are not understood.
Do you have a link to the CDC saying that? I found [0], which claims the rate went from 19% to 22% --- far from doubling.

So, I'm curious: what's the _strongest_ case one could make for including a more robust SAT solver as part of the exhaustiveness checking? Is there any reasonable place where this could matter? (Extremely autogenerated code?)
I'm much less certain of this, but I think Lean is better for non-mathematicians trying to learn more about math --- provided, that is, that you're set on playing with a proof assistant. I'm not sure I'd recommend that.
> As we oppose all government intervention in the marketplace, we favor the repeal of intellectual property laws. Disputes between inventors, creators, authors, artists, businesses, and other such entities should be resolved without government intervention.
This is madness. Without a notion of "property", there is no marketplace. Even the more extreme libertarians will generally agree that it is necessary for government to have police powers, partly to ensure that property rights are respected.
Now, one can argue (without being completely incoherent) that intellectual property should not exist as a concept, but that amounts to abolishing a certain marketplace, not preventing "government intervention in the marketplace". Moreover, denying property rights outright for intangible goods is a strong position, and not one I usually associate with libertarians.
Sometimes local third party politics is the only thing less sane than national two-party politics.
An important object-level question is "are trade deficits bad?". (I have no real opinion on this question, because hey, I'm not an economist --- none of this is about the object-level question!) For those who live under an even larger rock than I do, Trump sided with "yes", causing a predictable sorting of opinions in US politics.
The article leans very strongly in the direction of "no", stating above the fold:
> The notion that bilateral trade deficits are bad in and of themselves is overwhelmingly rejected by trade experts and economists.
There follow 5 citations, of which 4 are articles about Trump. (Three mention Trump in the title.)
The claim is repeated in the body of the article; it's the first sentence in the section "Views on Economic Impact". But the very next sentence is
> According to the IMF trade deficits can cause a balance of payments problem, which can affect foreign exchange shortages and hurt countries.
The paragraph structure makes it seem like this is a sentence in support of the thesis, but it's really not. And the very next sentence, again, is on negative effects of trade deficits:
> On the other hand, Joseph Stiglitz points out that countries running surpluses exert a "negative externality" on trading partners, and pose a threat to global prosperity, far more than those in deficit.
Note that this specific claim of "negative externalities" is very similar to the strongly politically coded claim that this article and its citations are so keen to claim is "overwhelmingly rejected". The following sentence is on negative effects of eurozone imbalances, but I'll stop quoting here.
I've seen similar patterns on other articles, but this is the clearest example. The article actually reads as something that was once a representative hodge-podge of arguments for and against, and then had to be "fixed" in the days of Trump and brexit to avoid confusing hapless readers.
It's relatively petty, but note another sentence above the fold:
> The notion of the balance of trade does not mean that exports and imports are "in balance" with each other.
This sort of pre-emptive heading off of common misconceptions is not encyclopedic. There are only seven sentences above the TOC, and one of them is this! (For instance, I checked the article on "quantum superposition", and no similar sentence is included, despite the obvious and common misconceptions.)
(for anyone who shares my pet hatred for researchgate)
So there must be a confounder. What could it be?
- Do the top schools all instruct students to always use spaces? This should have been partly taken care of when the author controlled for level of education though, right?
- Choice of editor? This seems like a weird one, but editor defaults are definitely linked to tabs vs spaces, and the survey didn't even collect data on this.
- Starting language?
- Total number of languages used? Spaces are tolerable in more languages than tabs are. Of course, I'd expect "both" to beat "spaces" if this was the case.
None of these strikes me as particularly plausible, except maybe the last one. This result is kind of bothersome, because it's big, obviously not a statistical fluke, and hard to understand.
EDIT: a past thread (https://news.ycombinator.com/item?id=20719010) suggested that some higher paying companies mandate spaces. This also seems plausible.
Not all people will agree that Tao's exposition is unclear. I linked it precisely because I found it more clear than other, "more physical" explanations (as a graduate student in physics, not math). When I was trying to understand gauge symmetry, it was that article that finally made things click for me. And, of course, many people I know would disagree, and point to other expositions as superior. That's the point: different people will not agree on what is well-written and what is incomprehensible.
You state "even pure mathematicians use numerical reasoning while trying to reason about a subject". Yes, some pure mathematicians do. Others use graphical reasoning. Others tend to lean purely on algebraic manipulations. Others tend to "reason" by analogy. And I'm sure there are other modes of thinking with which I'm too poorly acquainted to name. The result is that it's perfectly reasonable for people to disagree, quite strongly, about what is comprehensible and what is not, particularly people coming from different intellectual traditions.
It's a tangential nitpick, but I can't resist:
> [...] novella length explanation
As an undergrad I wanted to learn differential geometry, so I went to the library to pick a diff geo textbook. Well, I didn't want a difficult one, so I decided to pick the shortest book I could find --- surely that would be the easiest textbook to read? Haha.
As far as I'm concerned, the length of Tao's explanation is a strong merit.
