Ok, but how did the perimeter go from 4 to 24??

Just wait until you find out astronomy uses pi=10.
What?! Why?
Because when you’re dealing with measurements that are in the billions or trillions, you start working with orders of magnitude instead of specific numbers. A difference of a million miles is insignificant when the galaxy you’re measuring is 500 trillion miles away.
I think you’ve heard that trivia wrong. NASA uses 15 decimals of pi. The curiosity is that they don’t need to use more decimals even if many more are known.
I can’t think of any good reason to use 10 instead. The consequence would be if the galaxy is 157 trillion miles or 500 trillion miles away. That’s alot of space to disregard for no good reason.
Really depends on the situation. If you have to land an aircraft on the moon, you better get the value of π right.
However when estimating the distance to another galaxy, you’re not gonna fly there so you just want to know the order of magnitude: is it 10^9 or 10^15 miles away?
It may be a joke from xkcd, but I am not sure anyone in their right mind would bother using 10 instead of 3 or whatever.

Holy shit a site that explains xkcd jokes. You just made my whole week.
Let’s not pretend none of us have ever not understood an xkcd comic.
My brother has a PhD in astrophysics and he said similar likes like pi is 10.
I’m referring to Fermi estimations. Yes, NASA uses 15 decimal points for pi, but astronomers aren’t always making super precise calculations. As I mentioned in my previous comment, it’s used for estimating orders of magnitude. It’s helpful when precise calculations are complex, because any error along the way could be obscured or glossed over. A decent fermi estimation will help you identify when your precise calculation is wrong. This estimation can often be done quickly with very little actual data, because you’re only looking at orders of magnitude and rough numbers.
Let’s say you’re trying to calculate something complex. Your Fermi estimate takes like two minutes, and says that the answer is probably in the ballpark of ten million. Your precise answer takes an hour, and comes out to be nearly a billion instead. You can look at your fermi estimate for a minute or two to see if you missed a zero or two somewhere. And if you didn’t, then you need to scrutinize your complex calculation because you know you made an error somewhere.
Then why not use 1? It’s closer to pi than 10 and even easier to calculate with.
In the presence of a supermassive black hole, pi gets bend.
Amateurs, in MY field I use pi=100
In MY field, I use pie = tasty
calculations become a lot easier when you use pi=0
the pi(e) is a lie

I love how filth is in bold.
As an O notation enjoyer, I don’t get why people are so obsessed with constant factors. Is it exponential? Bad. Is it polynomial? Good. That’s it basically.
As a theorem prove enjoyer, I don’t get why people are so obsessed with variables in their exponents. Is it undecidable? Bad. Is it decidable? Good. That’s it fundamentally.
Gravitational Constant? Yeah, take 10… or 5… what gives?
There should be a version of this where the dad just wants to show his daughter a book he bought.
on it
Awesome, will look out for
There have been so many times I’ve been asked to consider π² as 10
… do we really wanna keep using a literal Neo-Nazi’s comics for memes, even if we’re changing the text?
It’s making fun of the comic, so why not? It brands the comic as a meme template rather than idiotic political agenda.
… do we really want to keep saying “this meme was originally racist and made by an asshole” under every goddamn meme?
Let’s take their work, transform it so it spits in the face of their idiotic ideology, and have a laugh
What? Can you enlighten us?
Guy who drew the original is really out there
It was made by this guy on Twitter: https://twitter.com/GPrime85/status/1697222846030721336
Yes. It’s a great format and obscures the initial message so why not?
Please link the inspiration too!
I wish I could but I wasn’t able to find it…
Oh it was only a comment, that’s why. Thank you sir!

I can’t make sense of the guys face in the last panel
Imagine someone who has his mouth wide open, tongue sticking up toward the roof of jis mouth, with his head tilted back as I screaming to the sky. You see the tongue and mouth from below due to perspective, as well as head tilt.
Ohhh that’s his tongue. Thanks I see it now

You round 2.14 down smh
