If there’s one food we can all agree on, it’s pizza. And at this point in your life, you’ve probably figured out your own go-to way to slice a pizza pie.

But as these two mathematicians showed, cutting a pie evenly is actually a complex geometry problem. Lucky for us, they figured out the “perfect” way to do it.

Joel Haddley and Stephen Worsley, researchers at the University of Liverpool, have adapted a method of pizza-cutting known as “monohedral disc tiling,” which uses curved polygon shapes to get the most slices out of the pie.

Using the traditional method of pizza-cutting, you end up with eight triangle slices. But using monohedral disc tiling, you end up with 12 perfectly even slices, though of different shapes.

Don’t get too excited about the new method, though. Half of those slices won’t have any crust on them, which could make or break this method’s appeal, depending on your stance on pizza crust.

Researchers Joel and Stephen discovered that you could use the same tiling method to divide a pizza indefinitely. You simply use shapes with a higher number of sides, known as 5-gons, 7-gons, and so on. The higher the number, the more slices you get.

“Mathematically there is no limit whatsoever,” Joel told NewScientist.
