News and Updates | IGDA INCOSE Théorie des graphes Un article de Wikipédia, l'encyclopédie libre. La théorie des graphes est une théorie informatique et mathématique. Les algorithmes élaborés pour résoudre des problèmes concernant les objets de cette théorie ont de nombreuses applications dans tous les domaines liés à la notion de réseau (réseau social, réseau informatique, télécommunications, etc.) et dans bien d'autres domaines (par exemple génétique) tant le concept de graphe, à peu près équivalent à celui de relation binaire (à ne pas confondre donc avec graphe d'une fonction), est général. De grands théorèmes difficiles, comme le théorème des quatre couleurs, le théorème des graphes parfaits, ou encore le théorème de Robertson-Seymour, ont contribué à asseoir cette matière auprès des mathématiciens, et les questions qu'elle laisse ouvertes, comme la conjecture d'Hadwiger, en font une branche vivace des mathématiques discrètes.

SAO/NASA ADS: ADS Home Page Gamasutra - The Art & Business of Making Games Wonders of Math - The Game of Life What is the Game of Life? by Paul Callahan Rules of the Game of Life Life is played on a grid of square cells--like a chess board but extending infinitely in every direction. A cell can be live or dead. A live cell is shown by putting a marker on its square. To apply one step of the rules, we count the number of live neighbors for each cell. A dead cell with exactly three live neighbors becomes a live cell (birth). Note: The number of live neighbors is always based on the cells before the rule was applied. In Life, as in nature, we observe many fascinating phenomena. The rules described above are all that's needed to discover anything there is to know about Life, and we'll see that this includes a great deal. Life Patterns A good way to get started in Life is to try out different patterns and see what happens. The R-pentomino is the first pattern Conway found that defied his attempts to simulate by hand. What Kinds of Objects Emerge in Life? Some other still lifes you will see are:
Atomic Clock Ensemble in Space (ACES) / Human Spaceflight Research / Human Spaceflight Atomic Clock Ensemble in Space (ACES) Atomic Clock Ensemble in Space (ACES) is a fascinating new ESA mission developed in cooperation with the French Space Agency (CNES) that will expand the range of research on the International Space Station (ISS). The ACES clocks will be installed on the external payload facility of the Columbus module. The frequency reference generated on-board the ISS will be used by a worldwide network of ground terminals to perform comparisons with the best available atomic clocks on the ground. Time flies on the ISS Short introductory video of ACES. The most precise measurement of time yet – in space – will be used to probe our knowledge of the fundamental laws of physics ruling the Universe. The ACES payload will be installed on the external payload facility of the Columbus module. ACES attached to Columbus. The most precise measurement of time yet – in space – will be used to probe our knowledge of the fundamental laws of physics governing the Universe. Conclusion

How does a light-mill work? [Physics FAQ] - [Copyright] updated June 1997 by PEG. Original by Philip Gibbs July 1996. In 1873, while investigating infrared radiation and the element thallium, the eminent Victorian experimenter Sir William Crookes developed a special kind of radiometer, an instrument for measuring radiant energy of heat and light. Crookes's Radiometer is today marketed as a conversation piece called a light-mill or solar engine. It consists of four vanes, each of which is blackened on one side and silvered on the other. When sunlight falls on the light-mill, the vanes turn with the black surfaces apparently being pushed away by the light. When this was realised, other explanations for the radiometer effect were sought and some that people came up with are still mistakenly quoted as correct. To understand why these common explanations are wrong, think first of a simpler setup in which a tube of gas is kept hot at one end and cool at the other. The vanes of a radiometer are not porous.

The Interactive Fiction Database - IF and Text Adventures Report on Reich Research from Group in Greece An introductory paper giving a Reichian perspective on zero point energy, global weather phenomena, free energy, modern science and non-science, misconceptions and associated dangers; as a contribution to discussions involving climate changes, disasters, and the quest for new energies. by Bababamoto, 2011-05-10 for Pure Energy Systems News This paper is based on our own research and experience. In view of the, for some, controversial nature of what we are trying to get across, it seems prudent to go into some detail about our scientific and psychological background: My brother and I have been in the fortunate position to be able to run our own privately funded research laboratory in for some years. Our father, who emigrated from Germany to Sweden in 1953, was apparently instrumentally involved with a highly secret development program involving nuclear weapons technology in Sweden between 1953 and 1962.
