@CentrumEuropy Czyli teraz jest superbohaterem

@Almost_Sure Please do, that would be great!

@Evolving_Ego @probnstat The expression in B indeed converges to σ² as n->infty. The problem is that B) doesn't make any sense as an answer to this question: it depends on n, and we're asked about a (specidic kind of) limit *as n goes to infty*.
It's a silly trap for testing reading comprehension, really

@chris_juravich @USDescartes @SyberMath @drpkmath @AssumeTheAxiom @CPierre67 I say it depends on what you're doing. If you want to have a square root function, you need to make some choice. In real numbers, the standard is that the positive solution is chosen. In complex settings, you pick a branch.
But you can also say that 2 and -2 are both sqrts of 4.

@LukePaulPL Rzeczywiście tak to zabrzmiało. Proszę zastąpić sobie w myślach słowa "byłem zaskoczony" przez "jestem pod wrażeniem" w poprzednim wpisie (bo ja nie mam możliwości edytowania...)

[Piotr Skalski @PStilance]

@LukePaulPL Nie, ale byłem zaskoczony, że Pan dał radę. Trudna algebra tam jest uprawiana, ja wymiękłem

@tunguz “Ed Witten isn’t brilliant” is certainly a take!

@kon_cuppy @__paleologo :)

[Piotr Skalski @PStilance]

@kon_cuppy @__paleologo Nobody's claiming it's applicable to the real world -- this uses the Zermelo well-ordering theorem!

@octonion I need to read the English translations someday

[Piotr Skalski @PStilance]

@VladimirGurevi2 @microfusio91945 Neat!

[Piotr Skalski @PStilance]

@chris_juravich @yureq That's always appreciated and a big advantage :)

[Piotr Skalski @PStilance]

@yureq @chris_juravich (Not sure if it's best suited for probability, but it's a good measure theory book I think)

[Piotr Skalski @PStilance]

@yureq @chris_juravich Have you seen Terence Tao's book?

[Piotr Skalski @PStilance]

@mathandcobb @martinmbauer Is it really wrong though?

@AcerFur So higher mathematics *is* in fact about counting up to higher numbers. Noted 😆

@genzforreadonly @octonion @JDHamkins Do hallucinogenic drugs cause AI hallucinations? :)

@chris_juravich @Diarytells Your typesetting skills are now much better than mine 😄
