To heat a slice of pizza, you probably wouldn't consider first chilling it in the fridge. But a theoretical study suggests that cooling, as a first step before heating, may be the fastest way to warm up certain materials. In fact, such precooling could lead sometimes to exponentially faster heating, two physicists calculate in a study accepted in Physical Review Letters.
