You need the kind of language that will strip the paint off the furniture. Alas, such language is hard to come by.

You may be interested to know that Alain Connes gave a new proof of Morley's theorem in 1998. It's based on a result about three elements of the group of affine transformations of the line. It's not super easy to find, though, as it's in a book from IHES.

I am totally indifferent to baseball.

My guess is that is what he meant. The same idea struck me almost the moment I saw the animation. Without it, it would have taken me (much?) longer.

Nice, but it should be Bayes' theorem. The man was named Bayes, not Baye.

And your vacation pay is actually earned in the previous year, so the first year of work, you get the vacation time but without pay.

Yeah, that's the socialist hellhole called Norway in a nutshell. 🇳🇴😀
But eight weeks of paid vacation? That's an overstatement. It's five weeks currently (25 workdays), with an extra six days for those over 60.
Of this, you have the right to three consecutive weeks in the summer months.

In all the sites I have passkeys on (not many), the old password based login (usually with TOTP 2FA) still works. There are also recovery codes, that you should copy and keep safe where available. Finally, I like to have two passkeys, one in the macos world (icloud) and one in bitwarden.
