Close Window Today is Stanislaw Ulam's Birthday! Happy Birthday Stan Ulam! Born: April 3, 1909 in Lvov, Poland Died: May 13, 1984 in Santa Fe, New Mexico Ulam was a very versatile mathematician who wrote numerous articles in the fields of set theory, group theory, topology, and mathematical physics, as well as several popular books about mathematics. Shortly after emigrating to the United States, he became a major contributor in the construction of the first fusion (hydrogen) bomb. While working on the problem of fusion, Ulam developed what is now known as the Monte Carlo method, a technique for solving a variety of mathematical problems by making use of random numbers and the laws of probability.

Stanislaw Ulam, the Hydrogen Bomb... and Nuclear Saucers Stanislaw Ulam was a Polish mathematician who came to the US in the 1930s on John von Neumann's recommendation and participated in the development of the first nuclear weapons at Los Alamos during WWII. When interest in bombs based on thermonuclear fusion began to grow in the late 1940s, Ulam returned to the New Mexico laboratory as a member of Edward Teller's "Super" working group, which was attempting to solve the seemingly intractible fusion problem. By all accounts, the partnership was not a smooth one, given Teller's famous temperament and ego. But by early 1951, the two scientists had devised a configuration of nuclear and chemical materials that would prove to be an extremely efficient means of igniting a fusion reaction. As John McPhee elegantly explains in The Curve of Binding Energy , one of the more important advances in nuclear weapons design in the post-war period involved a principle called "levitation," an improvement on the original implosion technology used in the "Trinity Gadget" and the Fat Man bomb that had destroyed Nagasaki. In the Fat Man implosion design, the high explosive shell and a heavy "tamper" material had rested in direct contact with the plutonium sphere at the center of the bomb. In the levitated concept, a gap between outer and inner portions of the nuclear core allowed the imploding shell to accelerate to tremendous speed before striking the nuclear material, greatly improving the compression of the core and the efficiency of the ensuing nuclear reactions.

70. Basic Principles Of Staged Radiation Implosion ("Teller-Ulam Design") technique for doing this is staged radiation implosion, also called the Tellerulam configuration after its original joint inventors, stanislaw ulam and Edward http://nuclearweaponarchive.org/Library/Teller.html

Based on excerpts from Section 2 of Nuclear Weapons Frequently Asked Qustions by Carey Sublette. "Teller-Ulam" Summary All thermonuclear weapons existing in the world today appear to be based on a scheme usually called the "Teller-Ulam" design (after its inventors Stanislaw Ulan and Edward Teller), or "staged radiation implosion" for a physically descriptive designation. Other designs have been devised that use thermonuclear reactions to enhance weapon yield in various ways, but the term "hydrogen bomb" can be taken to be virtually synonymous with this scheme. Basic Principles of Staged Radiation Implosion To make use of these fuels, the slower reaction rates must be offset by compressing them to densities hundreds or thousands of times greater than those of normal conditions. At any given temperature the reaction rate goes up with the square of the density, a thousand-fold compression gives a million-fold reaction rate increase. The work required to compress a gas is proportional to its temperature (at these pressures the physical strength of materials is negligible, and everything can be considered a gas). To minimize the work required for compression, or alternatively to achieve maximum compression for a given amount of work, it is important to keep the fusion fuel from getting hot until after the desired density is reached. The key to making large fusion bombs is finding a way for using the energy of an atomic bomb trigger to compress a mass of deuterium sufficiently for the D-D reactions to become practical, followed by heating of the mass to ignition temperatures after the proper density has been achieved. The technique for doing this is staged radiation implosion, also called the Teller-Ulam configuration after its original joint inventors, Stanislaw Ulam and Edward Teller (also reinvented independently by Andrei Sakharov and his associates, and by others in Britain, France, and China).

72. Prime Numbers And The Ulam Prime Spiral Pattern Tucked Away In The Number Sequen And the excitement about primes flared up even more in the wake of boredom of a devoted 20 th century mathmagician named stanislaw ulam. http://www.abarim-publications.com/artctulam.html

8.2 There's something about the Number Sequence Prime Numbers (2, 3, 5, 7, 11, 13, 17,...) There are many kinds of numbers and all different kinds come down to the same thing: they are amounts of something before the something is added. In a weird and far sought way, all numbers are equal, but some numbers are more equal than others. Those are the prime numbers, and primes are of royalty. Prime numbers are numbers that can only be divided by themselves and by one, which in both cases comes down to not dividing at all. Primes are diamond numbers. They're rock hard and can't be tampered with. Primes are the atoms of the number sequence and all other numbers are built from primes. And that's why we call them composite numbers. Composite numbers are molecules. Primes are atoms. And the number sequence is so arranged that some molecules (like 4) are a lot smaller than some atoms (like 2 -1). Nature obviously doesn't work like that, although some molecules (like H O) are a lot smaller than some atoms (like uranium). Still, molecule-atom ratios like 4 / 2 -1 do not occur in nature. Because nature isn't based on an infinite string of atoms. The number sequence is. In fact, it is provable that between a certain number N and that same number times two (2N) at least 1 prime number has to exist. (

He was 77. Ulam was affiliated with Harvard's Russian Research Center (renamed the Davis Center for Russian Studies in 1997) for more than 50 years. He twice served as the Center's director, from 1973 to 1976 and from 1980 to 1992. During his tenure, the Center became one of the leading institutions in the world for the study of the Soviet Union. Marshall Goldman, associate director of the Davis Center, described Ulam as "a Renaissance man who knew and had heard of and had thought about everything. If you wanted to know something, rather than go to a reference librarian, you would go to Adam." Emeritus , said: "Adam Ulam was an old-fashioned professor in the best sense of the word. The life of the mind was his primary occupation. Research and students were his main concerns. The Russian Research Center was his home – quite literally – for many decades. He really was one of the giants in a rich generation of refugee scholars, most of whom – alas – are gone." Edward Keenan, the Andrew W.

Work and Get Paid - Take the Cash but Get the Credit Someone deserves the renown associated with thermonuclear weapons ... and to the general public another person's name is associated with the credit. To see how this plays out, look over the Biographical Information , where a key excerpt reads: Ulam, Stanislaw M. (1909 - 1984) Stanslaw Ulam played a major role in the development of the hydrogen bomb at Los Alamos. Born in Lemberg, Pol., Austrian Empire [now Lviv, Ukraine], Ulam received a doctoral degree (1933) at the Polytechnic Institute in Lvov (now Lviv). At the invitation of John von Neumann, he worked at the Institute for Advanced Study in Princeton, N.J., in 1936, and lectured at Harvard (1939-40) and the University of Wisconsin, Madison (1941 to 1943). Los Alamos In 1943 he became an American citizen and was recruited to work at Los Alamos on the development of the atomic bomb. He remained at Los Alamos until 1965 and taught at various universities thereafter. Ulam had a number of specialties, including set theory, mathematical logic, functions of real variables, thermonuclear reactions, topology, and the Monte-Carlo theory. Fusion Bomb Working with physicist Edward Teller, Ulam solved one major problem encountered in work on the fusion bomb by suggesting that compression was essential to explosion and that shock waves from a fission bomb could produce the compression needed. He further suggested that careful design could focus mechanical shock waves in such a way that they would promote rapid burning of the fusion fuel. Teller suggested that radiation implosion, rather than mechanical shock, be used to compress the thermonuclear fuel. This two-stage radiation implosion design, which became known as the Teller-Ulam configuration, led to the creation of modern thermonuclear weapons.

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 Stan Ulam is also important in the early history of nuclear weapons . It was Ulam who showed Edward Teller 's early model of the hydrogen bomb to be inadequate.
