In mathematical set theory, an Ulam matrix is an array of subsets of a cardinal number with certain properties. Ulam matrices were introduced by Stanislaw Ulam in his 1930 work on measurable cardinals : they may be used, for example, to show that a real-valued measurable cardinal is weakly inaccessible .
Apart from 1 + 2 = 3 any subsequent Ulam number cannot be the sum of its two prior consecutive Ulam numbers. Proof: Assume that for n > 2, U n−1 + U n = U n+1 is the required sum in only one way; then so does U n−2 + U n produce a sum in only one way, and it falls between U n and U n+1.
Hence, his wife calls him demonyo (demon/devil). Hence, the title. Appeared only once and aired exactly one week before Christmas. Dingga: 2010: A parody of Darna with Michael V as Ading, a lame man who, whenever he ate a magical bubble gum will transform him into a gay superhero named Dingga. The enemies shown in this spoof were also inspired ...
Ulam's game, or the Rényi–Ulam game, is a mathematical game similar to the popular game of twenty questions. In Ulam's game, a player attempts to guess an unnamed object or number by asking yes–no questions of another, but one of the answers given may be a lie.
Ivy Mike, the first full test of the Teller–Ulam design (a staged fusion bomb), with a yield of 10.4 megatons (November 1, 1952) The Teller–Ulam design is a technical concept behind modern thermonuclear weapons, also known as hydrogen bombs.
Ulam was the one who suggested using a discrete system for creating a reductionist model of self-replication. [12] [13] Nils Aall Barricelli performed many of the earliest explorations of these models of artificial life. John von Neumann, Los Alamos ID badge. Ulam and von Neumann created a method for calculating liquid motion in the late 1950s.

The Ulam spiral is constructed by writing the positive integers in a spiral arrangement on a square lattice: and then marking the prime numbers: In the figure, primes appear to concentrate along certain diagonal lines. In the 201×201 Ulam spiral shown above, diagonal lines are clearly visible, confirming the pattern to that point.
