With an odd number of cuts, things start to get more complicated. Here the pizza theorem says that if you cut the pizza with 3, 7, 11, 15… cuts, and no cut goes through the centre, then the person who gets the slice that includes the centre of the pizza eats more in total. If you use 5, 9, 13, 17… cuts, the person who gets the centre ends up with less (see diagram).
Now, here’s the problem with the likes of Sheldon Cooper, while they figure out how to cut the damn thing, I’d have finished it and moved on. And you thought I didn’t have a life. hah!
