Your face when you realized that pi^2 is almost equal to g (the gravitational acceleration on Earth, sea level)

>> No.2180244

My face when:
dimensional analysis

>> No.2180253

i don't what g is and i don't understand what pi^2 means

and I vote

My face when I realized that e^pi - pi equals 20, but only on bug-free processors.

There's actually a good reason why that's the case, OP.

Actually, pi is measured in units of m^(1/2)/s^1

pendulums
2pi/T = (g/l)^1/2
set l = 1, T=2

>> No.2180327

>>2180317
That happened to me today. I collected data from 6 pendulums of different lengths, and when I plotted sqrt(L) vs T, the slope was 1/2. As a result, g = pi^2

No. ... But you're pretty cunning for an engineer.
Pi is a dimensionless value - you gloss over the dimensional conversion in your calculation above as it would have a magnitude of unity.

You know, gravity does extend from mass in a spherical shape. You probably just reverse engineered g.

This is why dimensional analysis is important because if you get confused you say something like this that makes no sense.
Isn't there a xkcd about this too?
