Need a new party trick? Mathematicians from the University of Liverpool have developed fancy geometric designs that can be used to cut a pizza into equally sized slices.

Joel Haddley and Stephen Worsley expanded on a previous design that shows it is possible to cut a pizza into 12 identical pieces by first cutting six curved pieces, and then slicing those in half. In mathematics, this process is known as monohedral disc tiling, and there is actually a precedent of using pizza slices to discuss the geometry of circles. The researchers from the University of Liverpool write, “Such tilings are produced on a daily basis by pizza chefs by taking radial cuts distributed evenly around the centre of the pizza.”
