Since Arthur and some of his companions are found in Welsh (Celtic) literature, it is only right to list their possessions here. Back to the Appendix French Legend Though, the Charlemagne legend doesn't belong here, they are sometimes listed in Arthurian legend, comparing the object between two different legends.

Relancé activement lors des années culturelles croisées France-Chine en 2004-2005, le jumelage entre Marseille et Shanghai, signé le 26 octobre 1987, fête son 25ème anniversaire.
A la clé, un nouvel accord de coopération fin 2012 et bon nombre de festivités dans les deux villes. Photo DRIE Culture, santé publique, sécurité incendie, développement économique et commercial, social, sport, tourisme… Nombreux sont les domaines concernés par les accords de coopération signés en mai 2005 et août 2009 entre Marseille et Shanghai. C’est à la suite de la « Semaine de Shanghai à Marseille » en 2004 et, réciproquement, de la « Semaine de Marseille-Provence à Shanghai » l’année suivante avec le déplacement d’une délégation de 350 personnes conduite par le maire de Marseille que les relations entre les deux villes se sont vraiment resserrées. Depuis, la coopération n’a fait que progresser.

The International Organization for Standardization (ISO) is an international standard-setting body composed of representatives from various national standards organizations. Founded on 23 February 1947, the organization promotes worldwide proprietary, industrial and commercial standards. It is headquartered in Geneva, Switzerland, and as of 2013 works in 164 countries. It was one of the first organizations granted general consultative status with the United Nations Economic and Social Council. Name and abbreviations The three official languages of the ISO are English, French, and Russian. The name of the organization in French is Organisation internationale de normalisation, and in Russian, Международная организация по стандартизации.

The Englert–Greenberger duality relation relates the visibility, , of interference fringes with the definiteness, or distinguishability, , of the photons' paths in quantum optics. As an inequality: The relationship was first experimentally shown by Greenberger and Yassin in 1988. It was later theoretically derived by Jaeger, Shimony, and Vaidman in 1995, and over a year later it was also mentioned by Englert, in 1996. The mathematics of two-slit diffraction This section reviews the mathematical formulation of the double-slit experiment. The wave function in the Young double-aperture experiment can be written as The function is the wave function associated with the pinhole at A centered on ; a similar relation holds for pinhole B. Is a position in space downstream of the slits. And are proportionality factors for the corresponding wave amplitudes, and is the single hole wave function for an aperture centered on the origin.
Where is the radial distance from the pinhole. then we get: . How to Build a Collective Intelligence Platform to Crowdsource Almost Anything. Introduction The MIT Center for Collective Intelligence recently published an important overview of the theory and mechanisms behind successful crowdsourcing efforts. Their report, called “Harnessing Crowds: Mapping the Genome of Collective Intelligence“, can be found here. Their research reveals similarities behind many high-profile collective intelligence (CI) systems, including Threadless, Wikipedia and InnoCentive.
It then describes how these lesson can be applied to the design of other successful CI platforms. I call this work the MIT Approach to Collective Intelligence, which is a generic approach applicable to a wide range of problems and circumstances. This post explores how I have used the MIT approach in my own work and how you can use it to build your CI system. The MIT approach to collective intelligence According to the Center for Collective Intelligence, a good collective intelligence platform (CI) must address the following themes: What is to be accomplished? Conclusion. Mebae. Mirage topologique. Un article de Wikipédia, l'encyclopédie libre. En cosmologie, un mirage topologique est un hypothétique mirage, qui serait dû à la topologie de l'Univers.
Plus précisément, cet effet serait lié à la structure et aux raccordements topologiques de celui-ci. Ce mirage nous donnerait l'impression que l'univers est plus vaste qu'il ne l'est en réalité en démultipliant les sources « lumineuses » qui nous proviennent du cosmos : un peu comme une pièce tapissée de miroirs réfléchit infiniment son propre contenu. Origine de la théorie[modifier | modifier le code] Origine de l'illusion[modifier | modifier le code] Rappelons que la relativité générale stipule que les rayons lumineux se déplacent selon les géodésiques - les « lignes droites » - de l'espace.
Donc dans un espace analogue à la surface d'un tore, les rayons lumineux vont inexorablement revenir à leur point de départ.

The double-slit experiment is a demonstration that light and matter can display characteristics of both classically defined waves and particles; moreover, it displays the fundamentally probabilistic nature of quantum mechanical phenomena. The experiment belongs to a general class of "double path" experiments, in which a wave is split into two separate waves that later combine back into a single wave.
Changes in the path lengths of both waves result in a phase shift, creating an interference pattern. Another version is the Mach–Zehnder interferometer, which splits the beam with a mirror. This experiment is sometimes referred to as Young's experiment and while there is no doubt that Young's demonstration of optical interference, using sunlight, pinholes and cards, played a vital part in the acceptance of the wave theory of light, there is some question as to whether he ever actually performed a double-slit interference experiment.

On nomme lois scalantes, ou parfois aussi lois de puissance, un certain nombre de lois constatées le plus souvent empiriquement et où interviennent des phénomènes d’invariance d'échelle, d’où leur nom, ou parfois d’invariance de repères. Il arrive qu’on soupçonne leur validité dans des domaines autres que ceux pour lesquels elles ont été démontrées ; c’est le cas par exemple pour la Loi de Mandelbrot. Les plus connues sont : Loi de Zipf (constatée)Loi de Mandelbrot, généralisation de la précédente (démontrée)Loi de Pareto et principe de Pareto, dit aussi des 80/20 (constatée ; étudiée par Knuth dans The Art of Computer Programming, vol. 3, « Sorting and searching »)Loi de Benford Loi de distribution du premier chiffre dans des tables numériques ou des carnets d’adresses (démontrée)Courbe d'apprentissageDistribution de la vitesse des molécules dans un gaz.

The one-electron universe hypothesis, commonly associated with Richard Feynman when he mentioned it in his Nobel lecture, postulates that there exists only a single electron in the universe, propagating through space and time in such a way as to appear in many places simultaneously.
History Feynman's thesis advisor, John Wheeler, proposed the hypothesis in a telephone call to Feynman in the spring of 1940. He excitedly claimed to have developed a neat explanation of the quantum mechanical indistinguishability of electrons: As a by-product of this same view, I received a telephone call one day at the graduate college at Princeton from Professor Wheeler, in which he said, "Feynman, I know why all electrons have the same charge and the same mass" "Why? " "Because, they are all the same electron! " References External links Jagdish Mehra, The Beat of a Different Drum, The Life and Science of Richard Feynman, Oxford, 1994, pages 113–115.

( Chinese : 李 白 ; pinyin : , 701 – 762, also well known as , among other transliterations ) was a major Chinese poet of the Tang dynasty poetry period . Regarded as one of the greatest poets of the Tang Dynasty , often called China's "golden age" of poetry, Li Bai was both a prolific and a profound poet, as well as one who stretched the rules of versification of his time. Around a thousand yet existing poems are attributed to him. [ 1 ] Thirty-four of his poems are included in the popular anthology . In the area of Chinese cultural influence, Li Bai's poetry has been much esteemed from his lifetime through the present day.
His influence also extends to the West through many translations, adaptations, and much inspiration. Li (李) is the family name , or surname; however, he has been and is known by various names. The year of Li Bai's birth is generally considered to be 701. While she was pregnant with him, Li Bai's mother had a dream of a great white star falling from heaven. 處世若大夢, 胡爲勞其生. Forêt des songes.

Two-dimensional visualization of the Alcubierre drive, showing the opposing regions of expanding and contracting spacetime that displace the central region. The Alcubierre drive or Alcubierre metric (referring to metric tensor) is a speculative idea based on a solution of Einstein's field equations in general relativity as proposed by theoretical physicist Miguel Alcubierre, by which a spacecraft could achieve faster-than-light travel if a configurable energy-density field lower than that of vacuum (i.e. negative mass) could be created.
Rather than exceeding the speed of light within its local frame of reference, a spacecraft would traverse distances by contracting space in front of it and expanding space behind it, resulting in effective faster-than-light travel.

10 Abandoned Psych Wards Photographers Love Sneaking Into. Abandoned buildings have long held a fascination for me. They imply a mystery (what happened?) And a challenge (can I get inside and see?) As well as a thrilling bit of danger (guard dogs! Rape-happy squatters! My Strange Geographies photo essays grew out of my fascination with abandoned things (and expanded from there), and I actually did hit a mental hospital recently -- a few months ago, on an island just off Venice, Italy, of all places. There are many UrbEx photographers out there (the advent of high-quality, relatively cheap digital cameras that can take pictures practically in the dark helped spread the craze), but one of my favorites, and a friend of mine, is Martino Zegwaard, a seemingly fearless Dutchman whose pictures of skin-crawly places are imbued with a strange beauty.
