Aside from game night wars fueled by Monopoly, there are few arguments that will drive a wedge between family members faster than “who gets the biggest slice of pizza?” As we all know, very few pizzerias cut eight perfect slices; someone always ends up getting the short end of the crust.But fear not — mathematicians at the University of Liverpool have completed some very important research and discovered a method of cutting pizza into 12 identically shaped slices — no sibling rivalry required.
The catch is that this method looks a bit complicated, and requires some serious exotic geometry and knife-wielding skills. The recipe for slice shape perfection is known as monohedral disc tiling and results in six slices that form a star in the middle, with six other curved pieces forming the remainder of the pie around the outside.

“I’ve no idea whether there are any applications at all to our work outside of pizza-cutting,” says Haddley, who has tried out this method in real life. “But the results are “interesting mathematically, and you can produce some nice pictures.”
