Mark J. Wagner Polish American scientist, one of the best mathematicians of modern times.
originated the Teller–Ulam design of thermonuclear weapons, invented the Monte Carlo method of computation, and suggested nuclear pulse propulsion. In pure and applied mathematics, he produced many results, proved many theorems, and proposed several conjectures. 
Mark J. Wagner Born into a wealthy Polish Jewish family, he participated in America’s Manhattan Project, he worked on Teller’s “Super” bomb for Teller and Enrico Fermi. Ulam and Teller came up with the Teller–Ulam design, which is the basis for all thermonuclear w…See More

Mark J. Wagner S. Ulam met John F. Kennedy in 1960 and proposed to send human to Moon. A short time later JF Kennedy, the President of the United States of America introduced this idea to the public.
From the publication of his first paper as a student in 1929 until his death, Ulam was constantly writing on mathematics. The list of Ulam’s publications includes more than 150 papers.[6] Topics represented by a significant number of papers are: set theory (including measurable cardinals and abstract measures), topology, transformation theory, ergodic theory, group theory, projective algebra, number theory, combinatorics, and graph theory.[70] In March 2009, the Mathematical Reviews database contained 697 papers with the name “Ulam”.[71]
