SVT A L'AFFICHE - LeWebPédagogique | par Liliane Arnaud Soubie, professeur :cours de collège, EDD, jeux éducatifs, actualités scientifiques tout publicSVT A L'AFFICHE – LeWebPédagogique | par Liliane Arnaud Soubie, professeur :cours de collège, EDD, jeux Fentes de dessication dans un fond de lagune après les inondations de 1983 dues à un Niño. Après cinq ans d’absence, le phénomène El Niño est réapparu dans l’océan Pacifique tropical. La communauté scientifique annonce le développement dans l’océan Pacifique de l’événement El Niño le plus intense depuis le début du XXIe siècle… Ce nouvel épisode pourrait affecter de nombreuses régions du globe jusqu’au printemps 2016 Voir l’article de Grégory Fléchet / CNRS Le journal: El Niño. Anomalie, vue par satellite, de la température de la surface de la mer et de la couverture nuageuse durant l’épisode El Niño 1997-1998, le plus intense du siècle dernier. El Niño ? Des précisions sur cette oscillation Elle consiste en un renversement de la circulation des alizés de sud-est dans le Pacifique sud mettant fin à la remontée d’eaux froides le long des côtes du Pérou. Comparaison entre une situation normale dans le Pacifique tropical et une situation El Niño. Sources partielles de l’article: CNRS IRD

Nice Neighbors a webgame for science! (961/965 solved in this set) research mode! Thanks for playing! How to play Play the tutorial (button in the upper-right corner)- it only takes about 30 seconds. Or watch this video (2:30): Or read these words: Click and drag to move the dark blue nodes from one spot to another. About this game Update As of January 2015 all of the solvable puzzles have been solved, and the remaining ones have been proven by an exhaustive computer search to be unsolvable. Short version An unsolved mathematical question in digital topology has been transformed into this web game. Long version In a Summer 2014 project at the Fairfield University REU in mathematics, Jason Haarmann, Meg Murphy, Casey Peters, and Chris Staecker discovered an interesting question about which abstract "digital images" are homotopy equivalent to smaller digital images. Each "experimental level" in the game with at least 8 points represents a specific digital image whose reducibility is not known. Technical Links

Algorithms: Design and Analysis, Part 1 - Stanford University About the Course In this course you will learn several fundamental principles of algorithm design. You'll learn the divide-and-conquer design paradigm, with applications to fast sorting, searching, and multiplication. You'll learn several blazingly fast primitives for computing on graphs, such as how to compute connectivity information and shortest paths. Finally, we'll study how allowing the computer to "flip coins" can lead to elegant and practical algorithms and data structures. Learn the answers to questions such as: How do data structures like heaps, hash tables, bloom filters, and balanced search trees actually work, anyway? Course Syllabus Week 1: Introduction. Week 2: Running time analysis of divide-and-conquer algorithms. Week 3: More on randomized algorithms and probability. Week 4: Graph primitives. Week 5: Dijkstra's shortest-path algorithm. Week 6: Further data structures. Recommended Background Suggested Readings No specific textbook is required for the course. Course Format

multimaths.net | Ressources pédagogiques en mathématiques Grid Paper PDFs Free Online Graph Paper / Grid Paper PDFs Downloadable and very printable, I find these PDFs extremely useful. Tip number one! Though I do return the correct header for a PDF, sometimes Explorer gets confused when downloading... So if you're running Windows, you may need to right-click a link and choose "Save link to disk". Tip number two! Some people may need to turn off the option in Adobe's Acrobat reader "shrink to fit" which may resize the grid slightly to fit your printer's printable area. Tip number three! If you want the hexes aligned with the other edge of the paper, just make your paper size "11 x 8.5" and print the result in landscape mode!

Automata - Stanford University About the Course I am pleased to be able to offer free over the Internet a course on Automata Theory, based on the material I have taught periodically at Stanford in the course CS154. Participants have access to screencast lecture videos, are given quiz questions, assignments and exams, receive regular feedback on progress, and can participate in a discussion forum. Those who successfully complete the course will receive a statement of accomplishment. The course covers four broad areas: (1) Finite automata and regular expressions, (2) Context-free grammars, (3) Turing machines and decidability, and (4) the theory of intractability, or NP-complete problems.Why Study Automata Theory? This subject is not just for those planning to enter the field of complexity theory, although it is a good place to start if that is your goal. The concepts of undecidable problems and intractable problems serve a different purpose. During the course, I'm going to prove a number of things. Course Syllabus

Le cartable de M.Orain (Collège Goupil Beaugency) FRACTAL MACHINE The shape you see is the combined output of the controls below. Mouse over them to see what they do. If the page gets too slow, turn some of the parameters down. Press H or ~ to hide the controls. Find out more in this blog post. This slider changes the first and last angles of the motif. Skew the motif asymmetrically. Set the number of times each line is substituted for the motif. Segment the motif into more or fewer pieces of equal length. Change the base shape the fractal is drawn on. Add lines that stick out from the motif's corners. Mirror the motif at every level of the fractal.
