i got that feeling too, that couldn't have been einstein.
because most of the facts the studentslists can be deduced from evidence or have at least
a valid background (e.g. there is heat, cold, darkness because humains perceive them all the same, or at least the vast majority).
I mean the we don't know which colour the sky is, but we perceive it as blue ( most of the time anyways), so people name the sky blue. So this doesn't needs evidence, it is more of a definition, and so is that the lack of light is called darkness.
