Maybe I’m dense but shouldn’t the clock be:
- H: 0.01667
- M: 1
- S: 60

Stupid question… are these RPMs true??

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.

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.

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.

He also put 33 instead of 33 and ⅓. Get the pitchforks!
TheOakTree@lemm.ee 5 months ago
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.
