>>11727891All were at one point scientists. Not like you put Bill Nye there.
Maybe Tyson is the least of them, then Sagan, but both were still scientists.
I like Kaku the least, but he worked in normal academic string theory wankery non-theless. If you don't count that, then put him last.
Hawking definitely had a physicist career, but of course he's painfully overrated.
Nothing can be said against Curie, Einstein and Feynman.
I'm really unsure why you say 2. If we say Feynman was a lesser Einstein (both being hardcore theroreticans), then I suppose you mean Curie and Einstein?
