Breakthrough could lead to more precise lasers, traffic speed guns
(NEWSER) - A team of physicists say they’ve managed to “tie light in knots” using holograms and abstract mathematics. The breakthrough could have a host of practical applications, including more precise lasers and traffic speed guns. It’s also the first physical application of “knot theory,” a branch of mathematics inspired by the winding of shoelaces, which was previously believed to be totally abstract. More»
