This proof is a banger, but I have a proof that the eqation x^n^ + y^n^ = z^n^ has no integer solutions for n > 2 on my buttocks

Unfortunately I can't share it with you, as there might be british people on this website.

[–] Enkimaru@lemmy.world 1 points 6 days ago

Your tattoo is likely not a proof, but just a formula. And if I am not mistaken: the assumption that the formula is true, got disproven a few years ago.

Actually, currently all the Lemmy instances are blocking the UK because of the new porn law. So you are safe.

Oh, you mean... there are currently more Argentines than british on lemmy? Escucharon muchachos? Ganamos*

You're wrong.

Source: British not using VPN... Well, not for Lemmy, anyhow.

[–] Ilovethebomb@sh.itjust.works 13 points 1 week ago

Oh, that's hilarious.

[–] Lumisal@lemmy.world 13 points 1 week ago

Does that mean reddit.uk is gone now?

(It's also why I thought "buy European" being hosted there was dumb, especially post Brexit)

I have discovered a truly marvelous proof of this, which my buttocks is too narrow to contain

Formatting is wild there my dawg. Fermat's sufficiently recognisable tho' that I know what it meant to say

The proof is actually pretty simple but the character limit on my instance is too small to contain it

Me to the tattoo artist: "show your work"

[–] socsa@piefed.social 45 points 1 week ago (2 children)

I mean you do you but the most famous undergrad level proof might not be the flex you imagine it to be.

[–] FuglyDuck@lemmy.world 32 points 1 week ago (2 children)

and basic algebra is a bigger flex?

[–] socsa@piefed.social 45 points 1 week ago (1 children)

I suppose if you really pressed me on it I'd say Pythagorean theorem is maybe less tryhard due to its innocence. It's like the Casio watch of basic maths. Euler's identity is like the cheapest Omega. You're kind of hoping the observer recognizes the brand is expensive, but doesn't know more than that.

[–] teft@piefed.social 16 points 1 week ago (1 children)

You better define all those symbols in the same tattoo

[–] cannedtuna@lemmy.world 20 points 1 week ago (1 children)

I wonder if it’s a pun or joke. Like her back is C. Idk what else to make to it.

Yeah, at least do the fundamental theorem of algebra, or Stokes' theorem.

For anyone else that needs the reminder, the one on the right is Euler's formula.

[–] kautau@lemmy.world 50 points 1 week ago (1 children)

It’s amazing how much a visualization can help to explain

Like I had to take a few higher level math classes in college since I majored in comp sci, and the difference between a professor just writing notation on a board and rambling for an hour vs a professor explaining application and using visuals to explain was such a wild difference in the quality of classes

[–] rothaine@lemmy.zip 26 points 1 week ago (1 children)

Meanwhile Euler was coming up with all this shit while being blind

More specifically, the power series proof of Euler's identity.

[–] MonkeMischief@lemmy.today 9 points 1 week ago (1 children)

Oh sweet! That's the magic that makes rotations work intuitively in Blender and game engines! :D

... Still can't say I understand it but I sure am grateful!

[–] logicbomb@lemmy.world 9 points 1 week ago (1 children)

I thought the magic that makes rotations work intuitively in games was quaternions.

[–] MonkeMischief@lemmy.today 6 points 1 week ago* (last edited 1 week ago)

Wait, you're totally right! I had it turned around!

Quaternions avoid the gimbal lock issue, and are more efficient overall, but they're a bit more complicated to understand.

Euler is more user-friendly on the editing side of things, and easier to understand, but it's got some shortcomings. (Maybe that's why I thought this, perhaps some tutorials were telling me to use Euler at first...? Hm.)

Both are an option in Blender and Godot for instance, because one might suit a given situation better than the other.

[–] BreakerSwitch@lemmy.world 29 points 1 week ago (7 children)

Listen, Pythagoras gives us the hands down best way to tell intelligent life visiting earth that we're intelligent. Drawing a right triangle and marking the sides with 3 dots, 4 dots, and 5 dots immediately demonstrates that we are a sapient species that has developed mathematics with no need for a device or language. Of course, we're all carrying devices these days, so maybe that's no longer relevant.

Girl on the right has the kind of ink I'm actually a little shocked nobody I've slept with has had. Though my ex wanted Euler's formula as a tattoo.

[–] CluckN@lemmy.world 25 points 1 week ago

They both pale in comparison to the Grover’s Algorithm tramp stamp that your mom has.

[–] DrDystopia@lemy.lol 14 points 1 week ago (2 children)

I'mma be honest with you guys, I don't get either. And none of the maths either.

[–] rc__buggy@sh.itjust.works 13 points 1 week ago (11 children)

Left is basic algebra/geometry that allows anyone to find a basic square angle. It's used daily in construction. You can learn how to use it today by searching "345 triangle"

Super useful for anyone, even meatheads like me.

Pythagorean theorem

[–] victorz@lemmy.world 13 points 1 week ago

Left is the Pythagorean equation. Pretty simple, basic equation that's easy to use and apply.

Right is an elegant mathematical proof, so a little more "attractive" if you like maths I suppose. 😄

[–] bjoern_tantau@swg-empire.de 14 points 1 week ago (1 children)

Pythagoras is at least something I regularly use in day to day life.

I think that is LaTeX on her arm. How sexy.

[–] Gladaed@feddit.org 10 points 6 days ago

No it's not. latex is the source code

I've had thoughts about math formula cheat sheet tattoos while in school
