Alex Bellos demonstrates cutting a cake using scientific principles.
Brilliant!
In 1906, Sir Francis Galton proposed a way to cut a round cake so that the exposed inside does not go stale. For some reason, his method of cutting a cake did not catch on. Numberphile explains it to us, which is interesting in a geometric way, but only truly useful for people who have a round cake and find themselves eating it over several days all by themselves. Which is sad. Galton must have been a lonely man. When I bake a cake, there isn’t any at all left by the next day. And if you do eat cake by yourself, here’s a tip: you don’t have to put it in the refrigerator.
