Well, I guess... chemists think it's kinda cool, but really... who trusts a chemist? All of us? Shit. You mean I can't just blow this off 'cause it's hard? Fine.

Fine.

FINE! I'm doing it, OK?!




Gets to the point around 3:00 minutes in and makes a pretty good and simple argument to understand it over the next 2 minutes.

I learned about it in Thermodynamics in college, but it hasn't come up since then in my work.
My actual definition without research would have been:
It's one of about 30-ish forms energy can take and sneak around in, and it's one of the less intuitive ones.
Turn out I would've been kinda right and kinda wrong because it's a sum of other energies, so not technically one of the forms energy can take, but more just a convenient package of a couple forms of energy to make math easier.
