Imponderables: The Solution to the Mysteries of Everyday Life

Feldman, a media consultant and lover of the obscure, here addresses scores of questions that one may have contemplated, but to which no answers are readily forthcomingwhy certain traffic jams occur and clear up without apparent reason, why the word ""Filipino'' is spelled with an F and not a Ph, why unleaded gasoline costs more than leaded. In an engaging, sometimes jocular manner, Feldman communicates an impressive amount of information: a piece on popcorn develops into an examination of the economics of running a movie theater; the answer to a question on laundry bleach is worthy of an encyclopedia. Occasionally, Feldman offers such a fresh way of looking at a phenomenonas when he discusses why people cry at happy endingsthat he makes us see it as if for the first time. This is an entertaining collection of trivial and not so trivial information. Illustrations not seen by PW. (April 21)
