Ue bêtise de Cambrai. La soixantaine de très sérieux participants (chercheurs, philosophes, juristes, artistes) au colloque sur la sérendipité organisé du 20 au 30 juillet à Cerisy (Manche) par le CNRS, a reçu, comme mise en bouche, cette friandise. La petite histoire raconte que le berlingot naquit, dans les années 1830, d'une bourde d'un apprenti confiseur. Les clients en raffolèrent tant que la recette fut analysée et conservée.

Héberger ses vidéos sur YouTube ou utiliser un compte Hotmail, est-ce encore Internet ? A l'origine, le net a la particularité d'être un réseau où rien n'est centralisé, où les données ne sont pas stockées dans un seul et même endroit. Or pour Benjamin Bayart, président de FDN (French Data Network), le plus vieux fournisseur d'accès Internet français, cette structure est en danger.

THE END OF UNIVERSAL RATIONALITY [3.31.09] A Video-Talk With Yochai Benkler

World Wide Web@20

| No Comments
Il y a vingt ans naissait un projet qui allait transformer le monde à jamais. Tim Berners-Lee remettait à son chef Mike Sendall un document intitulé « Gestion de l'information : une proposition ». « Vague, but exciting» (un peu vague, mais prometteur) commenta Mike Sendall, qui donna à Tim Berners-Lee le feu vert pour développer son projet. L'année suivante, le World Wide Web était né.

Brain researchers trying to understand the neural basis of religious belief have concluded that the brain has no special region or network for this task. Rather, it depends on general networks that exist for other purposes.

A team led by Dr. Jordan Grafman of the National Institute of Neurological Disorders and Stroke questioned volunteers about their religious beliefs while monitoring the blood flow in their brains with a scanning machine. Extra blood flow is assumed to reflect the activity of neurons in a specific region of the brain.

Different networks of neurons sprang into action when subjects were asked their view of three sets of statements about the religious beliefs, Dr. Grafman and colleagues report in this week's Proceedings of the National Academy of Sciences.

Scientists will warn this week that rising sea levels, triggered by global warming, pose a far greater danger to the planet than previously estimated. There is now a major risk that many coastal areas around the world will be inundated by the end of the century because Antarctic and Greenland ice sheets are melting faster than previously estimated.

Watchmen

| No Comments
The anticipated film Watchmen, based on the 1980s DC Comics 12-part comic book series (later adapted as a graphic novel), hits theaters tomorrow. Die-hard fans of the original publication may fret over its faithfulness to the series, but studio execs also worried about their movie's faithfulness to science. To set their minds at ease, they placed a call to Jim Kakalios, a physics professor at the University of Minnesota.

Google menacé ? Pas encore mais...

Curieux dimanche du côté de San Francisco. La blogosphère locale s'enflamme autour d'une proposition peut-être géniale, sûrement enflée. Il s'agirait d'un nouveau type de moteur de recherche capable de révolutionner le web et de faire trembler Google. Mais nous n'en savons presque rien, si ce n'est le nom : Wolfram Alpha .
