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 in…

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 permutation…

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 mino…

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 …

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…

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 s…

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 dep…

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…

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. The…

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 v…

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 uni…
