Abstract
Stanislaw Ulam is probably best known among pure mathematicians for one of his early works with Karol Borsuk: the Borsuk-Ulam theorem. The special case of this theorem in dimension 2 is usually dubbed as “there are always two antipodal points on earth’s surface that have the exact same temperatures and exact same pressures.” Hidden
behind is a reasonable assumption that temperature and pressure vary continuously on the surface of the earth. Among well-read non-mathematicians, he is probably well-known for his central role in the Manhattan Project. Few people would know that he invented the Monte-Carlo method, that he came up with the concept of cellular automata, and that he even made important contributions to the moon landing project and mathematical biology.
