I'll add a question: if it makes no difference, does the weight on a scale increase because a bird (or a plane, or, for that matter, Superman) flies overhead? This question is the basis for a bizarre joke about somebody delivering 3 tons of parakeets in a 1-ton truck, and having to pound on the wall behind him "to keep 2/3 of them in the air." Jack Paar told it on the Tonight Show and Hugh Downs, his announcer, stopped the show dead by explaining that 3 tons of parakeets could not possibly fit into a panel truck (Downs must have a physics degree... or maybe even something worse, like math). As for me, every morning I get on my bathroom scale with my parakeet, Braak, standing on my finger. If the reading is greater than that for the previous day, I give Braak hell. Yes, I know this isn't physics. Turn off those accelerators. -- D Gary Grady Duke U Comp Center, Durham, NC 27706 (919) 684-3695 USENET: {seismo,decvax,ihnp4,akgua,etc.}!mcnc!ecsvax!dgary
