Glad you like it :)
And hey, you never know. You’re a person on the internet I don’t know; I wouldn’t want to look like a fool in front of you and your deer furry lover if that happens to be your situation

Grow up. The imgflip watermark is clearly visible in the meme, and it’s an ancient meme format.

Euclidean geometry enjoyers in shambles
- Comment on Order of magnitude is a hell of a drug 2 weeks ago:
I guess n would be infinite in the limit I’m looking for. I’m looking at this in like a “musing about theoretical complexity” angle rather than actually needing to use or know how to use pi on modern systems.
For the record, I realize how incredibly pedantic I’m being about the difference between the irrational pi and rational approximations of pi that end up being actually useful. That being said, computational complexity has enough math formalism stink on it that pedantry seems encouraged

You sound like an involved and caring father. Rock on, dude
- Comment on Order of magnitude is a hell of a drug 2 weeks ago:
Do said atomic instructions produce pi though, or some functional approximation of pi? I absolutely buy that approximate pi is O(1), but it still seems like a problem involving a true irrational number should be undecidable on any real turing machine
- Comment on Order of magnitude is a hell of a drug 2 weeks ago:
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

“is not like you do calculations by hand anyway”

- Comment on Order of magnitude is a hell of a drug 2 weeks ago:
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

The real comment mvp. You deserve every positive vote my post got
- Comment on Order of magnitude is a hell of a drug 2 weeks ago:
Somebody else already said it, but that’s what the title is.
Longform: for 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

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

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

- Comment on JUST DO PSYCHEDELICS LIKE NORMAL PEOPLE 1 month ago:
“Drugs” is a pretty wide net, and yeah most of them would make it more difficult. Someone who isn’t me once told me that psychedelics make it a lot easier to follow really abstract thought, and that comes in handy when trying to imagine theoretical geometries our brains and other sensory equipment didn’t evolve to comprehend
- Comment on JUST DO PSYCHEDELICS LIKE NORMAL PEOPLE 1 month ago:
No no, I think there’s a misunderstanding here. If you can accurately describe to me what an n-brane is or have ever used terms like “deformation in the local topology”, I assume you’ve done SIGNIFICANTLY more psychedelics than most people. I’ve never had easier access to psychedelics in my life than when I spent most of my time near the math buildings at uni.

Telomeres are a structure on DNA. These things, aglets, are a common metaphor used to describe the function of telomeres as aglets basically do for shoelaces what telomeres do for DNA

- Comment on If I snapped you back in time 650 years right this very second, how would you use your current knowledge to succeed? 2 months ago:
I could probably discover electricity, depending on where I landed. Jewelers of the time could make wire, copper was common, and magnets (lodestones) had been discovered. Realistically though I’d be a dumb giant (ie, speak no known languages of the time and statistically I’d have like a foot on the “tall” people of the era). I’d probably try to find some party trick that looked like magic to people of the era then hope that people would welcome and try to integrate me rather than burning me as a witch. Then I’d probably die in a week or two anyway to some disease lol

- Comment on Given how paintball guns work, could you swap paintballs for a waterballs? 2 months ago:
Paintballs are trickier than just a water balloon. They have to be rigid/strong enough to survive the blast of co2 or compressed air that propels them, then they have to be soft enough to break on impact without harming the other player.
They also just aren’t that messy. I worked under the table as a referee at a Paintball place when I was 13, and we played such that gameplay didn’t stop when refs were doing paint checks. We’d toss people out if they were intentionally focusing on us but I got lit up probably 10+ times a day, every weekend for 2 years. My jersey and slider pants came clean in the wash every time, and to this day the only lasting blemishes are the shredded fabric on the knees/elbows/ass from when I dove and slid a lot.
