I love how fediverse things use 'client-username' @ 'server-domainname'

And they look like email addresses,

And email is old and we all know about it but it IS federated! :DD

And it's like, user@domain.tld is just the syntax of a user address in a federated system, and email was the only federated system anyone knew about so we thought of things in that syntax as "email addresses" when they're really just federated addresses! \:D/

Often, when I am reading a good book, I stop and thank my teacher. That is, I used to, until she changed her number.

Survived the real analysis midterm.

The classical Axiom of Choice is obviously wrong: the more tasks you have to do, the more difficult it is to choose where to start, now recall that there are infinitely many tasks…

If you study Buddhism and learn to accept the impermanence of all things, you don't need to do backups anymore.

PSA: the Q in my screenname is not an abbreviation.

I'm trying to come up with a good concrete example of a sequence that is bounded but doesn't converge and a subsequence that converges in order to illustrate the Bolzano-Weierstrass theorem. So far all I've got is the harmonic function, which is kind of a trivial and uninteresting subsequence ;) Anyone have suggestions?

Hmmmm should I watch Free Speech or GOD TV?

The course is still open and free. Six short modules, three on mathematical mindset and three on actual math strategies:

Survived the first two weeks of an accelerated four week real analysis class that i'm taking this summer, meets 3 hours a day four days a week. Please send help... our first midterm is on Monday!

I found a nice tool for looking up a LaTeX symbol; it lets you draw the symbol and then it attempts to guess which one you were trying to draw: detexify.kirelabs.org/classify

"I'm impressed -- her gestures are pretty much what I'd expect from someone actually teaching this proof. Did they use a math double for this scene?﻿"

I love this YouTube comment. I want to be a math stunt double in the movies too.

I enrolled in a class on continuous mathematics, and the first day’s challenge is: can you find a rational number between any two real numbers? My intuition said no, but the teacher seemed to be saying yes...
