Le Bitcoin peut-il transformer l'apprentissage des mathématiques ? Bitcoin , la monnaie virtuelle qui fait beaucoup parler d’elle , pourrait avoir une influence sur la manière dont les enfants apprennent à compter. C’est l’hypothèse de Nicola Smith, présidente des innovations à Engauge , dans un article publié sur Wired . En effet, l’argent a un rôle clé dans l’apprentissage des mathématiques. C’est l’intégration concrète d’une notion abstraite à la réalité, permettant une découverte puis une maitrise plus intuitive des opérations. Nous disposons déjà d’exemples prouvant que la technologie peut être un formidable catalyseur d’apprentissage . D’après l’auteure, la meilleure solution se trouve aujourd’hui dans l’opportunité de connecter les univers numérique et physique à l’école. Retrouvez l’intégralité de l’article de Nicola Smith ici !

bitcoin logic To understand Bitcoin, one must first understand what its function is. Bitcoin, technophilic headline-grabber of contemporary times, is a cryptocurrency. What this means is not that the transactions are encrypted, but the method by which the units of currency exist is guaranteed by cryptography. To keep anyone from messing with the log, computers all around the world are building the blockchain, in a processed ‘mining’ (which is frankly a misnomer and a bit confusing). How many computers are working on the mining process? The reason that so many computers are working on mining is the reason for the misnomer—computers are awarded new Bitcoins in a random lottery, which works out to be generally proportional to how much computing work you put in to the network. This begs the pointed question: isn’t this a huge waste of resources? One might be tempted to put the answer to this question in terms of economic incentives. But this neglects an important fact.

TECNOSAPIENS La ciencia ha buscado en varias ocasiones definir la frontera entre el ser humano y el resto de los animales. Encontrar qué es lo que nos hace distintos, especiales. Hubo varias teorías parciales al respecto, con hipótesis centradas en el lenguaje, interacción social, capacidad craneal y uso de herramientas. Lo más probable es que la romántica línea divisoria no sea más que un borrón achaparrado con muchas manchas, y sea el todo resultante mucho más que la suma de las partes. Es por eso que podemos ver ejemplos de lenguaje elaborado, sociedades complejas, grandes cráneos y usos de herramientas en distintas especies animales. No sólo en la humana. Si cambiamos la palabra herramientas por la palabra tecnología, obtendremos una sutil diferencia que puede que nos haga confrontarla instintivamente con el reino animal. Es por eso que ninguna especie posee una tecnología ni remotamente comparable con la nuestra.

Bitcoin’s creator is Japanese mathematician Shinichi Mochizuki, says hypertext inventor Promotional posters for the new Everest movie recently appeared in New York City subway stations, and these days I travel to and from work with a strange lump in my throat. Everest, which opens in wide release in the US today (Sept. 25), is based on the true story of how eight people died in a storm on the world’s tallest mountain in 1996. It’s the same story that Jon Krakauer told in his bestselling book Into Thin Air. It was, until last year, the most deadly accident in Mount Everest’s history. Then on April 18, 2014, an ice release killed 16 climbers on the mountain. I was there, and my feelings about it are still a mess of contradictions. But when I watched the Everest trailer online a few weeks ago, I couldn’t stop shaking. I fretted about writing this article. But I’m still going to tell you all about it. I started reading books about mountaineering in grade school, and in college I developed an academic interest in the Himalayas. I was mostly worried about altitude sickness.

Bitcoin is ludicrous, but it tells us something important about the nature of money There was a great piece in the satirical news source The Onion a few years ago in which it “reported” that Fed chairman Ben Bernanke experienced a moment of existential panic during a congressional hearing as he paused, shook his head, and said, “It’s just an illusion . . . Just look at it: meaningless pieces of paper with numbers printed on them. Worthless.” Sayeth the Onion headline: “U.S. Economy Grinds to Halt As Nation Realizes Money Just A Symbolic, Mutually Shared Illusion.” It's all just an illusion, man. Which brings us to bitcoin. Bitcoin really is a tiny market in the scheme of things, and its recent gyrations mean that the dollar, euro and yen have nothing to fear from the competition. We can all agree that the dollar bills in my wallet are money, as are the quarters and dimes in the jar on my dresser. The common thread here is that money has almost nothing to do with physical form. Rather, what makes money money is what you can do with it. Bitcoin exacerbates that problem.

Bitcoin's Impact On So-Called Social Issues This morning, I awoke to an individual on Twitter letting me know, in no uncertain terms, that bitcoin and social issues were unrelated. Since literally everything is related to everything else in some way, I’ll assume what he meant is that bitcoin and social issues are particularly far apart in terms of overlap. This is of course absurd. While “social issues” is a term which needs to be defined prior to further discussion, the “social issues” that particularly interest me are issues of poverty, class, mobility, equality of opportunity and access to resources. Access to banking and credit Credit is one of humankind’s most important innovations. Bitcoin addresses this inequity in two ways. Second, the Bitcoin protocol offers the promise of Smart Contracts. Remittances and fighting oppressive regimes The ability to transfer money globally is a very powerful tool in the fight against poverty. In addition, bitcoin offers an escape hatch to people trapped under oppressive regimes. Charity

Bitcoin : fantasmes et menaces autour de la monnaie P2P La monnaie virtuelle Bitcoin suscite bien des fantasmes et conserve son lot de mystère. Générant des mouvements spéculatifs violents sur sa valeur. Un bref rappel des fondements s’impose avant d’aller plus loin : Bitcoin est présenté comme un logiciel libre et publié sous la licence MIT. Elle exploite une technologie P2P pour fonctionner sans autorité centrale. « Par le biais de ses propriétés uniques, le Bitcoin rend possible des usages prometteurs qui ne pouvaient pas être couverts par les systèmes de paiement précédents », précise la version française du site officiel de la monnaie virtuelle. Le doute subsiste sur la paternité du concept : Bitcoin serait « une amélioration significative d’un concept imaginé par Wei Dai, appelé b-money dans un document d’avril 19993 et du concept ‘bitgold’ décrit en 2005 par Nick Szabo ». Un certain Satoshi Nakamoto déclare avoir travaillé sur son concept pendant deux ans entre 2007 à 2009 (contribution disponible via le site P2P Foundation). Vraiment ?
