There’s an old story about that. Possibly apocryphal, but here goes: IBM mainframes used to come with documentation in ring binders. Some pages might indeed be marked “This page intentionally blank”. And they would from time to time send ou

You can't know. However, it is a consequence of the axiom of choice (AC). You can't know if AC is true either; but mathematics without it is really really hard, so it usually assumed.

Heh. To borrow an idea from xkcd (measuring gas consumption as area): The kWh measures energy, right? And energy is force times distance. So energy divided by distance is force! Let’s all start measuring EV consumption in newtons, folks. It

Even worse with just two digits for the year! 01/02/03 could be 1 Feb 2003, or 2 Jan 2003, or 3 Feb 2001. Let’s just be thankful no one ever uses any of remaining three permutations.

71. So far, the oldest to respond. Only a tiny minority of readers are likely to respond, though. And all you will learn from the responses is the age disribition of that tiny minority! Who knows how well that correlates with the totality o

Good point about pluralization. I tend to be confused about that because we don't pluralize units in Norwegian (except the equivalent of degrees). But confusingly, in English, you sometimes see people trying to pluralize the abbreviati

If you’ll excuse a bit of trivia: SI units named after people are not capitalized. So we have newton, joule, weber, kelvin, named after Newton, Joule, Weber, and Kelvin. (But their abbreviations are capitalized: N, J, Wb, K.)

I could have sworn it was Asimov, but now I’m not so sure. As I remember it, the problem was communication with astronauts in the outer reaches of the solar system.

That makes no sense, and is not consistent with video evidence. Max flaps (40 degrees or so) are typically used only for landing. That is very obvious when you see it! Usual flap setting for takeoff is on the order of 5–15 degrees.

They have a RAT (ram air turbine) that deploys automatically under specific conditions. It’s basically a turbine providing electric and hydraulic power. It was almost certainly deployed on the accident flight. It will only power the most cr

Too late to edit further, but I should add that there could be many reasons for the apparent failure to flare. I did not intend to speculate that the pilot is to blame. That is for the crash investigators to figure out.

A properly scathing resignation letter catches media attention better than anything you say after being fired, which would be interpreted by many as whining.

Indeed. Likely a wing tip strike, the right wing was ripped off, then the left wing is of course still flying so its lifting force rolls the plane over until that wing hits the ground. I think it stayed attached, so after that, the plane ju

I guess if we all add our favourite papers, we’ll end up with a very long list indeed. My own additions: As we may think by Vannevar Bush, and then something on Project Xanadu. There doesn’t seem to be any foundational paper on the latter,

They can, but they need to learn the proper techniques. In a country like Norway with a high proportion of electric cars, I think all fire departments know the drill by now – even if they never had to do it themselves. Most important: Don’t

Electric cars don't burn more often than gas cars. And most electric car fires don't involve the high voltage battery at all, but originate in the 12 volt wiring. That said, high voltage battery fires do happen, and they are much

> sometimes the reviewer selection is an utter crap shoot Indeed, but when someone of Tao's caliber submits a paper, any editor would (should) make an extra effort to get the very best researchers to referee the paper.

Or cheese slicer publishing, as you are selling your cheese one slice at a time. The practice is usually frowned upon.

by hanche 2y ago
Normally, referees are unpaid. You're just supposed to do your share of referee work. And then the publisher sells the fruits of all that work (research and refereeing) back to universities at a steep price. Academic publishing is one

It’s called the modified Julian day (MJD). And the offset is 2,400,000.5 days. In the Julian day way of counting, each day ended at noon, so that all astronomical observations done in one night would be the same Julian day, at least in Euro

That's done in the paper. Using a log(log) scale for time, measured in number of heat deaths of the universe. It's the most amusing part of the study.
