An improbably small amount, but knowing that may make the difference to
winning the trivia competition on a cloudy night at a star party.
By the way, speaking of star parties, where they do the laser range finding
to the reflectors on the Moon is from the McDonald Observatory, which we
visited in Texas, only a few miles away from where the Texas Star Party is held.
They'd probably say, "That's some more trivia for y'all". |
