It was great until my thumb slipped and I accidentally launched my telescope into the air at Mach 8.

TIL, I can totally enrich uranium with a modified dental drill.
Well, I’m off to start a new project, I’ll let everyone know how it goes.
Isn’t record 78rpm instead of 72rpm?
A lot of people won’t notice the difference.
You’d think the WR would a lot higher…
Yes.
It’s probably a PAL record instead of NTSC.
300 RPM for screwdriver ??? I guess it’s electric/machine ones, because no one in gods green earth can turn regular screwdriver 300 RPM
“Sidereal” pronounced /saɪˈdɪəriəl, sə-/ sy-DEER-ee-əl, sə-
I get I never learned phonetics but how tf do you pronounce upside down e
Like ethereal
Side real
meaning “of the stars” (from Latin, as opposed to Astral from the Greek)
used in modern English in “consider” (literally: with the stars, meaning to scrutinize the sky).

Nah, that’s sub + scribere: “write under”, as in signature. No relation to sidereal.
What would the bird version of “consider” be?
Conavis?
Stupid question… are these RPMs true??
Maybe I’m dense but shouldn’t the clock be:
- H: 0.01667
- M: 1
- S: 60
Yep, I’m a dumb, realized after a cup of coffee. Confirmed by the reply below.
I think I’m just going to go back to bed and skip today
Oh my god I’m full of caffeine and still wondered this same thing. In my defense it’s Friday afternoon and I’m tired.
Yes, you’re dense lol. The speeds are correct: the second hand that does one full Revolution Per Minute, the minute hand does one full Revolution Per Hour and the hour hand does one Revolution Per 12 Hours.
The sidereal telescope mount one seems to be right (approx 1 rotation per day).
Everything in XKCD is based on truth. That’s what makes it so funny… to geeks, at least.
Edit: God damn it, he put 72 instead of 78 RPM. I guess he does make mistakes after all…
He also put 33 instead of 33 and ⅓. Get the pitchforks!
Just a random thought, I always knew that 33 multiplied by 3 is 99 and 33 1/3 multiplied by 3 is 100, but I never considered that 33 is 99% of 33 1/3.
Woah…
He’s made typos a few times in the past too: https://explainxkcd.com/wiki/index.php?search=typo&title=Special%3ASearch&go=Go
I mean, technically, the record will play just fine. Everything will be slightly slower and lower pitched, but it’ll work. Think doom metal meets 1930s jazz.
Wow, dental drills spin stupidly fast. I never realized they’re jamming something in my mouth that makes a turbopump seem sluggish, and that makes the scariest laboratory centrifuge I’ve ever seen blush in shame.
Big centrifuges are quite scary. Think of how much mass they are moving at those speeds. In comparison, a small drillbit turbine being rotated by compressed air seems less scary.
