SAN DIEGO (AP) - Lots of high school kids ask, what good will all that math and science do? Well, a University of California San Diego scientist has beaten a traffic ticket in court. Dmitri Krioukov used physics and geometry in his appeal of a failure to stop citation. He was able to convince a judge the officer may have been mistaken when the prof was charged with running a stop sign. Krioukov says the calculations were simple and it took only five or ten minutes. He also wrote a four-page paper for the judge, titled "The Proof of Innocence." He says it was a minor inconvenience compared to hiring a lawyer and paying the $400 ticket.
