@nikitonsky I guess what I want to say is really that the process potentially went the other way around. First people noticed that the earth revolves around the sun in ~365 days. Then they wanted to encode this number in a unit of measurement. But the unit should be convenient, which imposes nice divisibility conditions on the number for a whole turn. The closest number to 365 which is divisible by 2,3 and 5 is 360. This might explain it. It might also be completely wrong
@nikitonsky I am not an expert, but it might be a combination of the fact that counting in groups of 60s was a thing (time is still counted like that for example; it has a lot of divisors, which is convenient) _and_ that the year is somehow very close to that πŸ€·β€β™‚οΈ
In particular, you wouldn't want the angle to be 365Β°, because you lose most nice divisors! Actually, for any number between 361 and 365, either the half circle or a third of a turn are not expressible with integer values πŸ€”
@randahl @shuro I'm not sure I understand your point then: do you want to stop the random individual who's not too technically competent (which your suggestion would stop), or state actors (you cite Putin in the initial post) for whom I struggle to see how effective this measure would be?
If you are scared that some random thief might break in your home and steal your computer, a lock is a good idea. If you're scared that Putin wants your computer, I don't see what a lock can do to protect it.
@randahl wouldn't the use of VPNs just circumvent the mechanism that you are outlining, or am I missing something?

@memdmp @luci Hi, I'm a maths PhD student and I wanted to let you know that 0 and 13 can very well be equal (of course not as elements of the integers, but [if you are interested] as elements of finite fields or other "counting systems"). My research only applies to such context, so for me the flowchart suggests to actually use AI, but I don't think I'm going to follow it πŸ˜‰

(As a similar example consider the clock: 12 and 0 are the same, and we all accept it!)

@olafurw another nice example is Miegakure, I'm still waiting for it to be released though πŸ₯²
(On Wikipedia there's a nice timeline of the various announcements πŸ˜…)

*IF* you want a flight ban that's MEANINGFUL, do this

- 4 hours by train, not 2.5 hours

- apply to ALL flights, inc. transfers and private jets

- turn connecting flights into connecting trains with guaranteed passenger rights in case of delay

Anything LESS than that and it's gesture politics

@corentin @jon That would be the best option (imho), and Trenitalia in Italy signals it very well imho: it has an option marked "Paris (all stations)". DB in my experience has not been so consistent: I just booked a train to Milan and I had to spell out the station, otherwise looking for trains to Milan would not find the one I was looking for πŸ™ˆ

@sil actually the whole problem of naming objects and ideas in mathematics is fascinating to me: ideas tend to be quite abstract, but you still want to give them a name which is as evocative as possible... And this can lead to many outcomes: poetry (for example, imho, Γ©tale morphisms by Grothendienck), antonomasia and also... Well, let's say more graphic examples (the monster group, the devil's staircases and blowups to name a few)
(Ah, we like to kill stuff in maths too πŸ˜…)
