I don't know you, nor what you know, nor what you don't know.
But one clearly has to be smart enough to be able to ask for what one doesn't know.
So i can't say "smarter" or "not smarter", we seem to share the same ability of understanding,
so it is thrown back at the theory of relativity, which you used to make your joke.
I am sure i can learn from you what i don't know already as you can learn from me what you do not know already but i know. If one wants so. Some prefer otherwise.
Second law of thermodynamics states: Energy flows from hot to cold objects.
OTOH one could say: "cooler" objects(systems in this case) suck heat from hotter objects.
Ectotherm beings ain't able to move when it's cold (below a certain temperature) but can move faster when it's warm/hot. Snakes/Lizards for example are ectotherm beings.
Humans are endotherm, they generate heat. The counterpart is Exotherm.
Endotherm is defined as chemical reaction(s) which causes a generation of heat(transformed).
Exotherm is defined as a chemical reaction(s) which sucks up heat resp. cools down.
Transmission happens.
But in fact it also might be appreciation or jealousy. What you meant. Did you?
Now i ask myself it is still phunny, when i had to explain a part of the joke.
