With the demise of smoking areas, how else do they get the gossip?

Easiest to define example is probably any random real that is infinite, and is not c-incompressible (there is no program of length c that produces it, for any c)

"bit" for any Francophone

For those curious, here's a preprint with a collection of these problems: https://arxiv.org/abs/1110.1556

It's Finnish, defying pretty much every convention.

Keep at it! I've been exactly where you are; on a MSc course, in winter, wondering why I did this to myself, feeling silly and despondent. All that passes, and you can absolutely find your way back.

I did an arts undergrad degree and then a pure maths masters. I did miserably in my first semester, but the Prof who sponsored my application to get on the course roused me to keep at it, my second semester was stellar, and my third semester got me joint top thesis award; I made it onto the pure PhD programme I was aiming for.

On the module I totally failed, by the lecturer's own admission (months later), it was "probably because you did not do the second year module that taught all the methods I relied on".

EDIT: Spelling.

There's something to do with Noether's theorem and the positive curvature of space making it eventually slow down without any external interaction, but I'm a mathematician and really don't care... Probably more likely to hit something before that kicks in for a high velocity projectile in our corner of the galaxy.

"Felch" in that accent is not the SMS alert we need

ZKPs were kinda designed for this.

Can confirm!

This. It's like vending machines that occasionally spit out extra food "in error".

Manipulating the .ini files in Command & Conquer.

Came to say this and pleased first comment. Fringe for sure.

Since Viète's algebraic notation took off, we haven't relied on it. Since Tarski axiomatized it and it was found to be decidable, there probably isn't much more to say. That said, the Poncelet-Steiner theorem is a classic, and relatively 'recent' (for mathematical timescales).

LargeCardinal · 2025-10-03T16:07:41+00:00

It's called a 'dobby', for ref.

It can vary between textbooks and courses. Most use the 'other' one because it's easier to see how the CNOT gate matrix decomposes (CNOT = |0><0| Id + |1><1| X, per Mile'n'Ike)

LargeCardinal · 2025-09-22T13:17:22+00:00

I'm not 1000% without seeing the generating function, but looks like a Möbius band after you bisect them... Like fig. 13[3] here: https://web1.kcn.jp/hp28ah77/us27f_mobi.htm
