The Borsuk-Ulam-theorem and the Tucker-lemma Let us recall the Borsuk-Ulam-theorem, a topological result which is often illus- trated to a layman by the claim that at any moment there is a pair of antipodal points on the surface of the earth with the same temperature and air pressure. Here, two points on a sphere are called antipodal if they are in exactly opposite directions from the sphere's center.
