The Secret to Activating Your Audience’s Brain. If you are like me, you are always looking for the latest and greatest ways to do things faster, better, and cheaper.

Personally, I get a thrill as I hunt for the best piece of hardware, software, or acclaimed process that will “change my life.” In the world of presentations, there is one key ingredient that will radically change them – specifically, how you engage your audience and how they perceive you. And, it’s a solution you have been hearing for quite some time now, but I want to take it one step further. Tell a story.

[EDIT: I rewrote the first couple of paragraph, because I realized a better way to say what I had in mind.]

There are many ways to define dimension and some of them give the same answer some of them don't. Depth is a sort of dimension. Perhaps not the most obvious, but one that works well in many situation. In general we count dimension by chains and the main difference between Krull dimension and depth is about the same as the difference between Weil divisors and Cartier divisors.

During the middle of one game, we went through the entire deck, so we shuffled the cards in the discard pile a few times and started playing again. Hmmm.

Ron Eglash: The fractals at the heart of African designs When Ron Eglash first saw an aerial photo of an African village, he couldn’t rest until he knew — were the fractals in the layout of the village a coincidence, or were the forces of mathematics and culture colliding in unexpected ways? Here, he tells of his travels around the continent in search of an answer. The Paradox of the Proof. On August 31, 2012, Japanese mathematician Shinichi Mochizuki posted four papers on the Internet.

The titles were inscrutable. The volume was daunting: 512 pages in total. The claim was audacious: he said he had proved the ABC Conjecture, a famed, beguilingly simple number theory problem that had stumped mathematicians for decades.

By Yasha Berchenko-Kogan A lot of math grad school is reading books and papers and trying to understand what's going on.

The difficulty is that reading math is not like reading a mystery thriller, and it's not even like reading a history book or a New York Times article. The main issue is that, by the time you get to the frontiers of math, the words to describe the concepts don't really exist yet. Communicating these ideas is a bit like trying to explain a vacuum cleaner to someone who has never seen one, except you're only allowed to use words that are four letters long or shorter. Games to entertain a commutative mathematician. I get the Tyne & Wear Metro in and out of work every day.

When I don’t have a quality periodical to peruse, I like to play games on my phone. I’ve found a few really good games for my phone that also exercise my maths muscle recently, so I thought I’d write a post about them to share the fun, and prompt you to recommend even more. Since I’ve got an Android phone, I’m no doubt missing some fantastic games on iOS, but lots of apps these days have versions for both big platforms. I’m also giving UK prices; prices in your country are likely the same numbers with different symbols in front. Quento Android, iOS; full version 75p. 17 Equations That Changed The World.

Description du Projet ARIVAF a pour thème l'étude de la variation de certaines propriétés arithmétiques dans les familles de variétés. On peut donner plusieurs définitions naturelles de la notion de 'famille' de variétés. Dans le contexte schématique, une 'famille' est un morphisme de schémas plat et de type fini. Dans le contexte catégoriel, une 'famille' est une catégorie fibrée sur la catégorie des schémas (ou des schémas sur une base fixée) dont on demande qu'elle ait de bonne propriétés, par exemple que ce soit un champ, voire un champ algébrique.

Mathematics of Planet Earth 2013. La2revelación, reseñas, artículos y opinión » Blog Archive » EDWIN ABBOTT Y LA TOPOLOGÍA EN PLANILANDIA. 13 Apr 2010, por Joaquin Gonzalez Alvarez :: Ensayos y estudios, :: Literatura: Comentarios de libros, ¬> Otros | 3,297 visitas A mediados del del siglo XIX el escritor inglés Edwin Abbott dio a conocer su novela Flatland, título que se traduce al español como Planilandia. Con la misma se apartaba drásticamente de su línea creativa dedicada fundamentalmente a temas de índole teológica, pues la obra que en ese momento presentó calificaba dentro del género fantástico al estilo de lo que hoy se conoce como de ciencia-ficción. Con singular maestría que le valdría alcanzar un éxito que hoy todavía se reconoce, aborda un tema clásico de la matemática: el número de dimensiones del espacio.

Claro está que algunas licencias narrativas debe tomarse el autor para el fluir de la trama cuyo interés logra mantener en todo momento. Tags: Edwin Abbott, Flatland, Planilandia, topología. Project Euler. K-MODDL > Tutorials > Reuleaux Triangle. If an enormously heavy object has to be moved from one spot to another, it may not be practical to move it on wheels. Instead the object is placed on a flat platform that in turn rests on cylindrical rollers (Figure 1). As the platform is pushed forward, the rollers left behind are picked up and put down in front. Yuri Manin - Science Lives - Simons Foundation. Yuri I. Manin’s richly diverse body of work justifies the term “Universal Mathematician.” In an academic landscape defined by discrete specialties, this work, as mathematics, philosophy or commentary, defies compartmentalization. Throughout his career spent investigating disparate branches of mathematics and physics, searching for – or pointing to – uniting characteristics, he has earned a host of accolades and an audience extending beyond these disciplines.
