11 Madcap maths

A In mathematics, the hairy ball theorem states that there is no non-vanishing continuous tangent vector field on even-dimensional n-spheres. In other words, given a ball with hairs all over it, it is impossible to comb the hairs continuously and have all of them lying flat

B In mathematics, the ham sandwich theorem states that, given n measurable objects in n-dimensional Euclidean space, it is possible to divide all of them in two halves with a single (n 鈥� 1)-dimensional hyperplane. In other words, if you make a sandwich from bread, butter and ham, you will always be able to slice it to share all three ingredients equally

C In mathematics, the ugly duckling theorem is an argument showing that, if you assume a finite number of properties combinable by logical connectives and a finite number of objects, any two different objects share the same number of (extensional) properties. In other words, a duckling is just as similar to a swan as two swans are to each other
