How to Cut a Cake Using Science

By Jamie Condliffe on at

If you're like most people, when you cut a cake you simply take a wedge out, making two lines from the edge straight into the centre. But there's a far, far better way to take a slice, based on maths that's over 100 years old.

In this video, mathematician Alex Bellos describes how you can use some science to take slices which make your cake last longer. Of course, depending on how much cake you eat that might not be particularly useful. But you will at least feel smug knowing you're doing it right. [Numberphile]
