oh no , the dog is drinking the wave equation

thanks tumblr I too simp for mathematics

This is the best horf I have ever seen. It's awful. I love it.

Ok so, I finally found a way to combine my obsessions with upsetting centaurs and 4-dimensional geometry, and his name is Horace. I will be taking questions now

The maths fandom is wild. “Real” and “imaginary” numbers? I think you mean canon and non-canon. You guys seriously go “this is my number oc his name is i and he is the square root of -1” when in numbers canon lore it’s actually impossible to square root a negative but sure whatever. “Complex numbers”? I think you mean a character x oc ship. “f(x) = 3x - 5”? That is self-insert fanfiction.

As a mathematician, this really pisses me off for two reasons

1. π is just about the sexiest thing there is, how dare approximately half the population choose anything else.

2. INFINITY IS NOT A NUMBER, IT IS A CONCEPT ok numbers are concepts to INFINITY IS A DIFFERENT CONCEPT THAN NUMBERS

Anyway I'm normal now

You all like bijective functions, but just wait until the trijective functions drop. Those are the real deal.

I do so love revolving door integrals. It gets even more fun and magical when you have something like \int e^x sin(3x) dx instead. (I'll let you cast that particular spell yourself; it's not that much harder.)

okay so we did this in class today Y'all wanna know the dumb ass solution to integrating e^x cos(x)?

first, you integrate by parts twice:

then, you set the entire integral equal to it like this:

then, you move the entire fucking integral over to the left hand side of the equation:

and then you can simplify to this:

and then this:

and boom you solved it.

the integral sign NEVER GOES AWAY and yet it's solved. what the hell man

The cool thing about doing math professionally is that you can work anywhere - on your walks, in the shower, as you fall asleep - just by rotating problems in your head. What's not so cool is that this drives you insane

A circle inscribed in a square covers 79% of the square.

A ball inscribed in a cube fills 52% of the cube.

A 4-ball inscribed in a hypercube fills 31% of the hypercube.

A 5-ball inscribed in a 5-cube fills 16% of the 5-cube.

⋮

A 9-ball inscribed in a 9-cube fills it up less than 1% of the way, yet there’s no room to fit a second ball of the same size without intersecting the first.

⋮

In dimensions 23 and up, you can fit a little cube in the corner of the diagram, such that the cube has a larger volume than the ball!

That's especially disconcerting because the 23-cube has 8,388,608 corners. Even if you inscribe the little red cubes in all eight million corners, your big cube will still be 99.5% empty space.

"not malicious" SEEMS PRETTY MALICIOUS TO ME!!

Look, I know this response isn’t malicious and simply an attempt at connection, but it’s still funny and incredibly frustrating that one of the most common responses a to “oh I’m doing/enjoy [math related thing]“ is “Oh man I HATE math” despite being an insanely wild response. Like, can you imagine this in a slightly different context?

“Hey, so what are your plans this weekend?”

“Oh, I’m just gonna hang out with my best friend”

“Neat, who is it?”

“David!”

“God, I HATE David, can’t STAND him!”

Like, in almost any other context this becomes hostile. What, you expecting me to shit on something I love with you??? Really?

I just genuinely don’t know what people expect to come of this response.

God, I love ∩ and ∪ being resized versions of ∧ and ∨. Very intuitive game design

[soullesz13]

do you guys ever see those accounts on instagram where they're like "i'm doing a phd in math at this extremely prestigious school" and then proceed to really slowly and dramatically prove theorems from undergrad analysis like the cauchy schwartz inequality or rolle's theorem? do we think they make money doing this? because there's certainly quite a lot of views on those videos? should we all be doing this? it probably takes them like 5 minutes max to edit that content
