Biographie de Edouard Lucas
Edouard Lucas est un arithméticien français également connu pour ses Récréations mathématiques. Enfant issu d'une famille très modeste (son père est artisan tonnelier à Amiens), il reçoit une bourse communale et réussit le concours d'entrée à l'Ecole Normale Supérieure, en 1861 (année de la promotion de Gaston Darboux, qui sera le seul à le précéder à l'Agrégation quelques années plus tard!). A la sortie de l'Ecole, il devient astronome adjoint à l'Observatoire de Paris, puis après la guerre franco-prussienne, il obtient une chaire de Mathématiques Spéciales à Moulins, de 1872 à 1876, où il épousera en août 1873 Marthe Boyron. Puis il occupe une chaire à Paris, d'abord au lycée Charlemagne à Paris, puis au déjà très prestigieux lycée Saint-Louis. Ses travaux mathématiques concernent la géométrie euclidienne non élémentaire (celle des transformations, en particulier la géométrie projective vue à travers ses homographies), et surtout la théorie des nombres.
Chaos & Fractals
Chaos is a relatively new and exciting science. Although chaos was often unfavorably viewed its early stages, scientists now perform active research in many areas of the field. Presently, there are several journals dedicated solely to the study of chaos. This website was written in conjunction with a talk given for Intermediate Physics Seminar of the Department of Physics and Astronomy at the Johns Hopkins University. It is intended to merely highlight a few of the more interesting aspects in the field of chaos. For further information, please consult the reference section of this document.
What’s the Difference Between a MOOC and an LMS? | Your Training Edge ®
Massive open online courses (MOOCs) have been around long enough that most people in the training industry have at least a general understanding of what they are. But there is still some confusion about how they differ from more familiar forms of elearning and online courses. In particular, a question I’m often asked is: “What’s the difference between a MOOC and a learning management system (LMS)?” The basic answer is that an LMS is a platform for hosting a course, while a MOOC is the course itself. In general, however, I don’t think the real question is about the difference between a MOOC as a course and an LMS as a platform. Small versus large (or massive) In theory MOOCs can accommodate an unlimited number of learners. Discrete versus continuous Traditional courses hosted on LMSs are usually discrete entities, meaning that that they start on a particular day, end on a particular day, have particular due dates, and so on. Content versus context This is a common distinction that is made.
coefficients binomiaux et la suite de Fibonacci / Café mathématique / Forum de mathématiques
Salut, Non, décidément, ton idée de gens qui savent et ne veulent rien dire, n'a pas de sens, cela confine à la paranoïa...La formulation des coefficients binomiaux, comme des Arrangements et Combinaisons est donnée en Terminale...D'accord ?Et les Maths ne s'arrêtent pas à la Terminale...Or, que trouve-t-on, entre autres, sur BibMath ?Tout simplement ceci : un dictionnaire de Maths...Et si tu le feuillettes, tu t'apercevras qu'il regorge de notions très pointues qui dépassent de loin le niveau Terminale...Mais ce que tu cherches ne s'y trouve pas !D'accord ?Alors, comment ton affirmation peut-elle être compatible avec ce fait ? la premiere est qu'un savoir maths est dependant d'un niveau scolaire:celui qui aide fait cela en tant que pédagogue afin que l'on avance dans les mathssi on lui demande telle ou telle formule qu'il connait il ne verra pas l'interêt pédagogique de la donner celui qui aide fait cela en tant que pédagogue afin que l'on avance dans les maths Vale tibi !

Golden ratio
Line segments in the golden ratio In mathematics, two quantities are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of the two quantities. The figure on the right illustrates the geometric relationship. Expressed algebraically, for quantities a and b with a > b > 0, The golden ratio is also called the golden section (Latin: sectio aurea) or golden mean.[1][2][3] Other names include extreme and mean ratio,[4] medial section, divine proportion, divine section (Latin: sectio divina), golden proportion, golden cut,[5] and golden number.[6][7][8] Some twentieth-century artists and architects, including Le Corbusier and Dalí, have proportioned their works to approximate the golden ratio—especially in the form of the golden rectangle, in which the ratio of the longer side to the shorter is the golden ratio—believing this proportion to be aesthetically pleasing (see Applications and observations below). Calculation Therefore, Multiplying by φ gives and History
