Recent revelations about Tiger Woods playdates have exploded his wholesome image in a Big Bang louder than the sound of an Esclade hitting a fire hydrant and tree. But it also has given a sales boost to "Get a Grip on Physics" by science writer John Gribbin. Photos released by the Florida Highway Patrol show the book in Woods' mangled car, amid shards of glass. That has been enough to lift the book to the 2,268th position on the Amazon sales list, up from 396,224th the previous day.
