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.

Stanislaw Ulam Nato in Polonia nel 1909, fu uno degli esponenti di maggior rilievo della scuola matematica polacca. Nella seconda metà degli anni Trenta emigrò negli Stati Uniti, dove visse e lavorò fino alla morte, avvenuta nel 1984, ricevendo importanti riconoscimenti accademici e scientifici. Durante la seconda guerra mondiale prese parte al progetto di costruzione della bomba atomica. Rimase poi, per oltre quarant'anni, collaboratore scientifico dei laboratori di Los Alamos. E' autore di più di 150 pubblicazioni, tra articoli, saggi e libri scientifici. I suoi contributi, che spaziano dalla matematica pura alla fisica nucleare, hanno esercitato una profonda influenza sullo sviluppo della matematica e sui suoi rapporti con altri settori della scienza e della tecnologia.

66. Basic Principles Of Staged Radiation Implosion ("Teller-Ulam Design") technique for doing this is staged radiation implosion, also called the Tellerulamconfiguration after its original joint inventors, stanislaw ulam and Edward http://nuketesting.enviroweb.org/hew/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).

A professor of applied mathematics, mechanical and aerospace engineering at the University of California, Irvine, he is the Stanislaw M. Ulam Scholar in the Center for Nonlinear Science (T-CNLS) at the Laboratory. Titi said he's been interacting with scientists at the Lab since the late 1980s. In 1997, he was an Orson Anderson Fellow Scholar for the Lab's Institute of Geophysics and Planetary Physics (IGPP). "The United States is a great land of opportunities, in particular, for science," he said. "This is the leading country in science. It's everyone's dream to come here, to avail themselves of the scientific resources and opportunities the United States has to offer." A citizen of Israel, Titi recently accepted a position as full professor at the Weizmann Institute of Science in Israel. He said he would be the first ethnic Palestinian citizen of Israel to be a professor in that scientific institute.

10. 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. (

I NTRODUCTION TO THE U LAM Q UARTERLY The Ulam Quaterly Journal is an electronic journal, which means that papers are submitted to editors and refereed as with any other journal. The difference is that the publication is available online. Editorial Policy The Ulam Quarterly Journal is dedicated to the universal character of Stanislaw Ulam's scientific interests. These interests led him to make contributions in logic, set theory, measure theory, probability theory, computer science, topology, dynamical systems, number theory, algebra, algebraic and arithmetic geometry, mathematical biology, control theory, mathematical economics, and mathematical physics. In this spirit the Ulam Quarterly Journal is devoted to the publication of original research and open problems in all areas of mathematics. The objective of the Journal is to disseminate qualified, refereed publications in the mathematical sciences. The Journal is published electronically at no cost to the subscriber, however a printed copy-of-record is kept. Submission of Articles Submission of article for publication in the Journal should be sent to the Electronic Editor. They will be refereed according to current practice and, upon acceptance, transcribed to a uniform format. There is no typsetting or formatting charge for articles which are formatted using TeX dialacts consistent with the requirements of the Journal. A page charge for electronic typesetting is however levied to the author for articles which are completely consistent with formatting requirements, or are not in electronic-readable format. In cases of hardship this page charge is waived. Contributions of articles covering diverse topics in mathematics are encouraged from all in the international mathematics community.
