SO I'm extremely drunk (the 5HT agonist kind) and for a second I couldn't understand the leverage effect, I actually had to google it

Turns out the leverage effect is pretty simple. You conserve energy, not forces.

Anyways, what's a stress-energy tensor and what's the whole deal with time translation symmetry being the reason we have to conserve energy in the first place?

Never understood the whole deal with symmetries being important.

Explain like I'm moderately clever and extremely drunk, /sci/
