27 Unhelpful Facts About Category Theory

Category theory is the heart of mathematical structure. In this video, I will drive a stake through that heart. I don't know why I made this.

You've heard of "The mitochondria is the powerhouse of the cell", now get ready for "A monad is a monoid in the category of endofunctors"

As a cocreator of this video, I very much like it.

You made an entire video, just to explain to *270 000* people _juuust_ enough about category theory, so you could hit them with the worlds nerdiest your mum joke. Respect.

“A coconut is just a nut” I absolutely lost it here, I don’t know why

[TeeMee]

You say category theory's one application is functional programming, but among programmers, there is a joke about asking of the applications of functional programming

Thanks a bunch! If i’m ever at a party where someone asks me to prove my intelligence by naming 27 facts about Category Theory, i’m set! (No, wait, I’m Class!)

A comathematician is a device that turns cotheorems into ffee.

I feel like I now know less math than I did nine minutes and twenty-five seconds ago.

This was extremely unhelpful! Thank you!

[antikovt]

Just admit it: this whole video's point was to teach us category theory in simplest terms possible so that we all understand the joke about the terminal object in a set of people and sexual relations.

The analogy of category theory being the "they are the same picture meme" is accurate. That is what makes category into a beautiful black whole where students fall and sometimes they never leave/recover

I hope you'll remain faithful and won't forget to make the serious follow up video

I spent 9 minutes 30 seconds watching a video learning about something I didn't know existed, and I'm pretty sure I know less now than when I started. I've since liked the video, subscribed, and hit the bell icon. Excellent stuff!

"Set theorists can construct the set of all things that cause you pain" im functing dead lmao, subbed

[joriskbos]

I have been learning australian category theory for a while now, and only recently found out it is actually isomorphic to regular category theory. If you flip everything upside down, it is just category theory!

This was all well and good until mathematicians discovered another even more abstract field of maths where the basis of communication is flustered frustrated hand waving.

[Pabloable]

"It's a good idea not to upset set theorists. They can construct the set of all things that cause you pain."

I'm invincible, though, because nothing causes me more pain than the set of all things that cause me pain. Well, unless they're using some model other than ZF. Then I'm screwed.

The main application of category theory is to make Haskell programmers look smarter than they are.

[LarryGarfieldCrell]

"What do you call someone who reads a paper on category theory" is my new favorite math joke. Damn, dude. Damn.

[treetheoak]

I don't know what's worse. The jokes in this video, the fact that I found them funny or the fact that I was genuinely disappointed that this was a joke video 😂
