MADRID, Spain (AP) - The Poincare conjecture involves topology, a branch of math that studies shapes. It essentially says that in three dimensions you cannot transform a doughnut shape into a sphere without ripping it, although any shape without a hole can be stretched or shrunk into a sphere. There is a catch: the space has to be finite. Imagine an ant crawling on an apple in a straight line. It can only walk so far before it's back where it started. Even though the apple has three...
