Oh, that’s easy. It’s just another word for wakalixes.
(Two irrelevant remarks: 1. Sorry, that webpage is eyeball-bleedingly ugly. 2. I conjecture that the last two words in the excerpt are why HPMOR!Harry chose to give his army a name that enabled him to call himself General Chaos. I suspect, more precisely, that at some point Eliezer read that bit of Surely you’re joking… and thought “hmm, General Chaos would be a good name for a supervillain or something”.)
Hm. If I had to give an answer, I’d say it’s the stuff that’s conserved because the laws of physics don’t change over time. But that’s pretty theoretical—maybe an extensional definition would be better.
I am a graduate student of physics and I am inclined to say that I now know even less about what energy is.

Maybe completely blanking on that question is a sign of having studied some physics?
The difference is that the guy who studies physics can explain why the question is difficult.
