I love this meme template lmao

[–] RQG@lemmy.world 40 points 1 year ago (2 children)

It has a dark past. But yeah it. Makes for a good meme.

The author is an alt-right weirdo, and the original comic is about "liberal" parents attacking her daughter for having a Bible.

[–] lugal@sopuli.xyz 18 points 1 year ago

For me it's part of the joke to make fun of this stupid guy.

Check through his other comics. It gets more racist the further down you go.

what's the past? link maybe if u can idk

[–] stebo02@lemmy.dbzer0.com 34 points 1 year ago (1 children)

The author is right-wing but makes fun of themselves without realizing it

[–] prumbles@lemmy.world 23 points 1 year ago (1 children)

Okay this is actually funny

[–] Vespair@lemm.ee 27 points 1 year ago

Yeah, a lot of their stuff is genuinely funny as satire, but the author truly has zero irony or satirical intent about any of it. They truly intend for these to be read and understood at face value. The shit they believe is real fucked.

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

Just wait until you find out astronomy uses pi=10.

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.

[–] bstix@feddit.dk 43 points 1 year ago* (last edited 1 year ago) (2 children)

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.

[–] stebo02@lemmy.dbzer0.com 11 points 1 year ago (1 children)

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?

[–] bstix@feddit.dk 19 points 1 year ago (2 children)

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.

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.

[–] al4s@lemmy.world 12 points 1 year ago

Then why not use 1? It's closer to pi than 10 and even easier to calculate with.

[–] famfo@social.dn42.us 18 points 1 year ago

In the presence of a supermassive black hole, pi gets bend.

Amateurs, in MY field I use pi=100

[–] Viking_Hippie@lemmy.world 6 points 1 year ago

In MY field, I use pie = tasty

[–] affiliate@lemmy.world 4 points 1 year ago (1 children)

calculations become a lot easier when you use pi=0

Gravitational Constant? Yeah, take 10... or 5... what gives?

[–] lugal@sopuli.xyz 10 points 1 year ago (1 children)

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.

[–] SrTobi@feddit.de 7 points 1 year ago

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.

There should be a version of this where the dad just wants to show his daughter a book he bought.

[–] silverwing@lemmy.world 6 points 1 year ago

There have been so many times I've been asked to consider π² as 10

[–] snaptastic@beehaw.org 5 points 1 year ago (5 children)

Please link the inspiration too!

What's funny is that physicists approximate and round way more than engineers do.
