When you cut a cake to produce a slice like the one in the picture above, you're actually performing a non-optimal cut. Why? If you don't eat the rest immediately, the inner surfaces of the remaining cake are exposed to the air, drying it out.

As Numberphile explains in the video below, the mathematician proposed a series of straight cuts across the entire cake. With this method, the remaining uneaten pieces can be pushed together so that no surfaces are exposed to the air for a prolonged period of time.
