# Put your science education to work. Cut pizza equally.

Learn how.

Or so they say. From Mashable:

It’s an age old question: Can cutting pizza ever be truly equal? …

But mathematicians Joel Haddley and Stephen Worsley at University of Liverpool in England believe they have cracked the code for perfect equality at the dinner table by cutting somewhat complex, curved slices — also known as monohedral disc tiling. More.

From Phys.org:

“I’ve no idea whether there are any applications at all to our work outside of pizza-cutting,” said Haddley in New Scientist. He has tried slicing a pizza in this way for real. But the results are “interesting mathematically, and you can produce some nice pictures.”

In short, the math is beautiful, but the pizza was probably a freaky mess.

Paper’s .pdf for the truly obsessive: “This paper gives new solutions to the problem: ‘Can we construct monohedral tilings of the disk such that a neighbourhood of the origin has trivial intersection with at least one tile?’”

The additional twist to their slicing is the restriction that “a neighbourhood of the origin has trivial intersection with at least one tile” – meaning, that at least one piece doesn’t touch the center.

Otherwise triangles would be fine, thank you.

Yes, DiEb, but that’s just the point. Some people mainly like crust. A locally trading firm sells dipping sauce to accommodate them. Now math has come to the rescue.

See, equality includes fairness of enjoyment, right? 😉

I make my pizzas square.

Well, some pizza places have a cutting template, with each space the exact same as the next. If it fits the pizza and is placed correctly, the slices will be equal.

It would be astonishing if this variation, which the authors mention, turns out to be possible:

to produce a monohedral disk tiling such that a neighbourhood of the origin is contained entirely within the interior of a single tile.
