Remember when you used to gripe about doing mathematical proofs in high school arguing a lack of real-life applications for it to be worth your while? Well, here’s how one man got off the hook for traffic ticket he received by using a math problem.
University of California-San Diego physicist Dmitri Krioukov was pulled over and issued a ticket for running a stop sign. While many wouldn’t go through the hassle of actually fighting this ticket in court, Krioukov is an exception — and he came prepared. io9 reports that he presented a mathematical paper to prove his innocence, aptly named “The Proof of Innocence,” and convinced the judge of his case.
