Welcome to c/science_memes @ Mander.xyz!

A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.



Rules

  1. Don't throw mud. Behave like an intellectual and remember the human.
  2. Keep it rooted (on topic).
  3. No spam.
  4. Infographics welcome, get schooled.

This is a science community. We use the Dawkins definition of meme.

More importantly, the full moon occupies 0.00077% of our sky, and is moving at 1.022 km/s around the earth. Suffice to say, if you land on the moon, you've done something incredible.

Yeah, it's a funny meme, but a basic understanding of physics reaaaallly flips it on its' head.

A basic understanding ~~of physics~~

Just "a basic understanding", yeah

The sun is 1.4 million kilometres in diameter, and it is surprisingly hard to throw something into it.

The more important question is how much of our night sky the moon takes up, and the answer is only 0.5 degrees.

How much is that in hamburgers? Sorry I only understand freedom units

[–] [email protected] 13 points 1 year ago (1 children)

Approximately .075 hamburger at arms length

[–] [email protected] 12 points 1 year ago (1 children)

I think you meant 5/64 of a hamburger.

I was told that the concept of decimal is too hard to understand compared to fractions.

[–] [email protected] 6 points 1 year ago

Unfortunately you're completely wrong here. Americans, burgers, and fractions don't mix well.

Third pound burger failed because people thought it was smaller than a Quarter Pounder

0.5° is 0.00873 radians

Turkey at distance is the proper measure here. That's a Turkey at I'd reckon 10 football fields.

Degrees are the freedom unit!

Having played Kerbal Space Program, orbital mechanics and ballistics make that diameter a lot smaller than one might anticipate. It's pretty easy to fuck up.

[–] [email protected] 19 points 1 year ago (1 children)

Yeah. But then you remember that space is big—so it’s pretty damn easy to miss.

You just won't believe how vastly, hugely, mind-bogglingly big it is.

[–] [email protected] 6 points 1 year ago (1 children)

you might think it's a long way to the chemist's...

[–] [email protected] 5 points 1 year ago

but that's just peanuts to space.

[–] [email protected] 16 points 1 year ago

I did the perfect shot, but then it just move out of the way >=\

Counterpoint:

Orbital semimajor axis of the moon (basically the orbit radius): 384400 km

Subtract earth's radius: becomes 378000 km above earth's surface at mean sea level.

Moon radius: 1737.4 km

tan^-1^(1737.4 / 378000) = 0.26 degrees

Conclusion: at best, assuming the moon is directly overhead and any glancing contact is a success, you can deviate maximally 0.26 degrees from a dead centre hit to hit the moon.

Good luck with that.

Thank you for doing the math on that.

[–] [email protected] 2 points 1 year ago

You're welcome! I thought it would be in the spirit of this community to put numbers to it, so that's exactly what I did.

[–] [email protected] 14 points 1 year ago (1 children)

Then you remember that he's in a 2'407'100 km void.

Ok. What country uses apostrophes instead of commas, or periods? I had thought that India's messed up comma system was the most irritating notation possible. I had never seen this notation.

[–] [email protected] 5 points 1 year ago* (last edited 1 year ago)

1,00,000

what in the actual hell.

ok so it kinda makes sense?

https://en.m.wikipedia.org/wiki/Indian_numbering_system

Still, wow.

[–] [email protected] 1 points 1 year ago* (last edited 1 year ago)

German i guess? The apostrophe for thousands, the dot for fractions. Using commas in numbers is the weird thing.

[–] [email protected] 11 points 1 year ago

I mean sure but the moon occupies less than 1% of the celestial hemisphere and its moving

[–] [email protected] 10 points 1 year ago

You could easily fuck it up more. Like, shoot in the opposite direction, or shoot for the sun. Hell, you could just blow the rocket up altogether. Guys, it’s so easy to fuck it up waaayyy more.

Sounds like someone hasn't considered the challenges of achieving escape velocity...

[–] [email protected] 9 points 1 year ago

Do not underestimate the amount of "Hold my beer" that people possess. :-P

[–] [email protected] 7 points 1 year ago (1 children)
[–] [email protected] 2 points 1 year ago

We just need to wait for a full moon so we don't miss.

[–] [email protected] 6 points 1 year ago* (last edited 1 year ago)

Yeah well escape velocity >: (

YOU DO IT
