Re: [math-fun] Flow of time

----- This reminds me of a variant of Einstein's explanation of relativity that I heard many years ago: If an old decrepit man sits holding an attractive young woman's hand for ten minutes, to the old man it seems like a minute and to the young woman it seems like an hour. (Sexist, yes, and heterocentric, so adapt it as you will; I'm relaying the version that I heard.) It could be that this version is due to (Isaac) Asimov. Dan, does this ring any bells? ----- Due to . . . whom? --Dan Daniel Asimov Visiting Scholar Department of Mathematics University of California Berkeley, California
