Is it actually? I'll admit im pretty rusty on time complexity, but naively I'd think that pi being irrational would technically make even reading or writing it from memory an undecidable problem
That's because your engineering ass needs things to be physical and sane. Physics is a field for the mentally unwell to sink further into insanity while incoherently scribbling greek letters on every available flat surface.
On a more serious note, yeah you absolutely have to be careful about where you apply really ambitious simplifications like that. There are plenty of mathematical regimes where you can use natural units (this is the term to look up if your interest extends further) and simplify your reference frame by a hell of a lot though. Setting the speed of light to 1 is also a hell of a drug, and brother I've got an addiction
Somebody else already said it, but that's what the title is.
Longform: a lot of calculations that happen in astro deal with distances so large so large that only order of magnitude changes actually meaningfully affect the end result. To connect to a more common topic, here's a joke.
"Whats the difference between a million dollars and a billion dollars?"
"About a billion dollars"
This joke works for the same reason; 1 billion is so many orders of magnitude larger than 1 million that (1,000,000,000 - 1,000,000 = 1,000,000,000) is only incorrect by ~0.1%, even though substituting 0 for 1 million in that equation seems ridiculous on the face of it. Substituting 1 for pi has similarly minimal errors (tbh it usually matters waaaaaaaaay less than .1% error) in a lot of astro math
I used to have an old man cat that was like that. He wanted to sniff everything that came in the house; not super urgently but he was always interested. It got hard for him to walk eventually and my girlfriend would always poke fun at me for carrying him around and holding him up to each new thing so he could investigate. He seemed happy about it though, he never stopped being interested in investigating
The most important thing I've ever been told about quantum is "shut up and calculate." Results don't seem physical? That's quantum. Results don't make sense? That's quantum. Shut up and calculate
Christian scientists on their way to tell you about how their evidence free belief in magic shouldn't affect how you view their ability to derive truth from evidence
My brothers wife. Started a conversation with me one day like "you know, my 2yo stepbrother has autism, and you don't act anything like him. I don't think you really have autism." I'm sure our difference in behaviour is because I don't have autism, not the fact that I'm literal decades older than him
I'm sure this is real and that guy is super talented, but I'd love to see a video of somebody who couldn't do this but still had confidence because they thought the video would be edited so the bread didn't all fall to the ground
Avatars are a psychological trick useful for building up sunk cost fallacy and making a user more likely to personally identify with a product. I don't have social media avatars for the same reason I don't have "nabisco" tattooed on my asscheek.
Depends on how much of a purist you are about the definition of parrying. I'd say the gameplay loop of missile command is basically a parry/counter mechanic
