21 GIFs That Explain Mathematical Concepts “Let's face it; by and large math is not easy, but that's what makes it so rewarding when you conquer a problem, and reach new heights of understanding.” Danica McKellar As we usher in the start of a new school year, it’s time to hit the ground running in your classes! Math can be pretty tough, but since it is the language in which scientists interpret the Universe, there’s really no getting around learning it.

index Australopithecus deyiremeda is the name of the new fossil hominid species discovered in the site of Woranso-Mille —in the central region of Afar, in Ethiopia. The discovery, described in the international scientific journal Nature, takes to another level the on-going debate on early hominid origin and evolution in Africa. The scientific team lead by Professor Haile-Selassie has found several fossil remains (upper and lower jaws and a collection of teeth) in the sites of Burtele and Wayteleyta, in Woranso-Mille, in the central region of Afar, about 50 kilometres north of Hadar and 520 kilometres northeast of the capital Addis Ababa. Experts have assigned these 3.3 – 3.5 million-year-old fossil specimens to the new species Australopithecus deyiremeda. Lucy was not the only australopithecus in the Afar region Map of Ethiopia showing the Afar Region. Scientists have long argued that A. afarensis was the only pre-human species which lived in the region between 3 and 4 million years ago.
Every Black Hole Contains a New Universe | Inside Science Inside Science Minds presents an ongoing series of guest columnists and personal perspectives presented by scientists, engineers, mathematicians, and others in the science community showcasing some of the most interesting ideas in science today. (ISM) -- Our universe may exist inside a black hole. This may sound strange, but it could actually be the best explanation of how the universe began, and what we observe today. It's a theory that has been explored over the past few decades by a small group of physicists including myself. Successful as it is, there are notable unsolved questions with the standard big bang theory, which suggests that the universe began as a seemingly impossible "singularity," an infinitely small point containing an infinitely high concentration of matter, expanding in size to what we observe today. But these theories leave major questions unresolved. The first is general relativity, the modern theory of gravity.
L’avenir de la programmation : le langage naturel Il existe deux types de programmation du langage naturel ; celle qui est effectuée par les grosses compagnies comme IBM et Apple, sur laquelle on ne possède bien souvent que quelques indications, et celle élaborée par les milliers de créateurs, souvent amateurs, de « chatbots » (programmes conversationnels). Celle-ci peut susciter l’intérêt du non-programmeur désireux de s’initier à cette discipline, car les outils sont disponibles et les procédés bien balisés. Les connaissances structurées : une tâche complexe et couteuse en ressources Comment fonctionnent les « gros » programmes de reconnaissance du langage naturel ? En gros, on peut travailler selon deux stratégies distinctes. A première vue l’approche structurée semble plus sûre parce qu’elle évite par trop les ambiguïtés liées au langage et ne met pas trop de pression sur le programme informatique. Un gros programme de reconnaissance du langage comme Watson, l’ordinateur champion de Jeopardy, utilise en fait la première approche.
Beautiful Mathematical GIFs Will Mesmerize You Digital artist and physics PhD student Dave Whyte is dazzling our computer screens with his mesmerizing GIFs that are the perfect marriage of mathematics and art. And we can’t stop watching them. Whyte shares his brilliant, procrastination-fueling creations on an almost daily basis on his Tumblr account, Bees & Bombs. Whyte studies the physics of foam and told Colossal that his first geometric GIFs riffed on computational modules that he was exploring as an undergraduate student. To create his eye catching animations, Whyte uses a programming language called Processing. [Via Colossal, io9 and Bees & Bombs]
La inmunoterapia contra el cáncer de piel que tiene un éxito nunca antes visto - BBC Mundo WolframAlpha : Une nouvelle sorte de science pour une nouvelle sorte de moteur de recherche Par Rémi Sussan le 03/06/09 | 6 commentaires | 6,463 lectures | Impression Aujourd’hui, vous avez sans doute déjà visité et utilisé WolframAlpha, et, selon vos préférences, vous l’avez trouvé plutôt extraordinaire, ou (surtout si vous êtes peu porté sur les chiffres), globalement décevant. Difficile pour l’instant de juger l’engin, qui n’en est, nous affirme-t-on, qu’à ses débuts (un truc à noter pour les collégiens et lycéens : il donne la solution des équations et trace les courbes de fonctions !). Car pour son créateur, le physicien Stephen Wolfram, également créateur du fameux logiciel Mathematica, pas de doute. Image : Stephen Wolfram, le créateur de Wolfram Alpha par Hybernaut. L’informatique est le socle de la structure du monde Qu’affirmait NKS (comme on a affectueusement surnommé ce livre) ? Autrement dit, le postulat en cours depuis Newton selon lequel les mathématiques étaient le langage de choix pour comprendre l’univers était une mauvaise habitude. Tout cela est bel et bon.
Visually stunning math concepts which are easy to explain History El hallazgo podría sentar las primeras pruebas sobre la existencia de 'físicas exóticas', absolutamente desconocidas para la ciencia actual. Un equipo internacional de astrónomos descubrió un 'súper-vacío' de 1.800 millones de años luz de diámetro, mientras se encontraba estudiando un área gigantesca del espacio, demasiado fría y raramente vacía. Esta región está situada relativamente cerca de nutro sistema solar, a unos 3 mil millones de años luz y, según el científico István Szapudi, a la cabeza del equipo, "se trata de la mayor estructura individual jamás identificada por la humanidad". Este 'punto frío' fue descubierto en la zona de 'súper-vacío', hace unos 10 años. El hallazgo, por entonces, asombró a la comunidad científica, dado que la aceptada teoría del Big Bang no prevé zonas frías de semejantes dimensiones. Fuente: The Guardian Imagen: NASA
