After coming to the United States permanently, Ulam was appointed an associate professor at the University of Wisconsin. In , he was asked by his friend John von Neumann to work on the Manhattan Project at Los Alamos. Ulam&#;s expertise was needed to ensure the proper design and construction of an implosion-type weapon. He was responsible for carrying out hydrodynamical calculations, which determine the behavior of solids at high temperature and pressure. This was crucial to the design of a proper explosive lens, which would be necessary to achieve perfect spherical implosion. Eventu

    Ulam was born in Lwów, Poland (then in Galicja, autonomous province of Austria-Hungary, now L'viv, Ukraine). His master in mathematics was Stefan Banach a great Polish mathematician, one of the moving spirits of the Lvov school of mathematics.

    Ulam came to the US in as a Harvard Junior Fellow. When his fellowship was not renewed, he served on the faculty at the University of Wisconsin, and supported his brother, Adam, who had fled from Poland on the eve of World War. While there, in the midst of World War II, his friend John von Neumann invited him to a secret project in New Mexico. To research the invitation, Ulam checked out a book on New Mexico from the University Library, and found, listed on the library check-out card, those who had successively disappeared from the campus at the UW. Ulam then joined the Manhattan Project.
