But it looks like the site has found plenty of users. The French startup just announced that it crossed two big milestones in March: It has more than 100,000 users curating links, and it received more than 10 million pageviews. Not only does that show the concept is resonating, but it also suggests Pearltrees could reach the scale where it can build a real business around advertising or by offering premium accounts for publishers. When you share links on Pearltrees, they show up as little circles called Pearls.
Wikipedia : Team Not to be confused with Teem. A team comprises a group of people or other animals linked in a common purpose. Human teams are especially appropriate for conducting tasks that are high in complexity and have many interdependent subtasks. A group does not necessarily constitute a team. survol géolocalisé 'Your own personal helicopter': New version of Maps will let you dive round exact 3D replicas of citiesHi-tech 'Google Planes' amass enough data to recreate buildings, bridges... even treesRe-vamp comes just as Apple 'plans to ditch Google Maps on the iPhone and iPad' By Eddie Wrenn Published: 20:07 GMT, 6 June 2012 | Updated: 16:18 GMT, 7 June 2012
Wikipedia : Pearl The most valuable pearls occur spontaneously in the wild, but they are extremely rare. These wild pearls are referred to as natural pearls. Cultured or farmed pearls from pearl oysters and freshwater mussels make up the majority of those that are currently sold. Imitation pearls are also widely sold in inexpensive jewelry, but the quality of their iridescence is usually very poor, and often, artificial pearls are easily distinguished from genuine pearls.
rituels (Ashanti group N.Y.) Dave Sanders for The New York Times Nana Acheampong-Tieku appeared in kente cloth and crown after being sworn in as the Ashanti chief of metropolitan New York during the first night of a two-day ceremony in the Bronx last month. More Photos » A scrum of men formed at one end of the hall and hoisted to their shoulders a wooden litter. It bore the newly inaugurated chief, wearing gold jewelry and a gold-studded leather crown, who bobbed above the celebrants and flicked a horsetail whisk and a golden scarf in a studied regality.

graphe3D In an impressive mix of visual sciences and sci-fi, the ICT Graphics Lab at USC has created a low-cost volumetric 3-D display that brings every kid's hologram dreams closer to reality. The process is not simple but can be defined through a few key concepts: spinning mirrors, high-speed DLP Projections, and very precise math that figures out the correct axial perspective needed for a 360-degree image (even taking into account a viewer's positioning.) USC ICT Graphics Lab's Volumetric Display Different companies have been trying to create a viable 3-D technology for years, but have found several barriers in their way: small viewing areas, high costs and the viewer disconnect with blurry optical illusions. The most recent attempts have included Helio Display that recreate 2-D projections into floating 3-D illusions, as well as Jeff Han’s Holodust, which involves infrared lasers 'lighting up' particles in space.

Talmud Name of two works which have been preserved to posterity as the product of the Palestinian and Babylonian schools during the amoraic period, which extended from the third to the fifth century One of these compilations is entitled "Talmud Yerushalmi" (Jerusalem Talmud) and the other "Talmud Babli" (Babylonian Talmud). Used alone, the word "Talmud" generally denotes "Talmud Babli," but it frequently serves as a generic designation for an entire body of literature, since the Talmud marks the culmination of the writings of Jewish tradition, of which it is, from a historical point of view, the most important production. The Name. "Talmud" is an old scholastic term of the Tannaim, and is a noun formed from the verb "limmed" = "to teach." In the second place, the word "talmud"—generally in the phrase "talmud lomar"—is frequently used in tannaitic terminology in order to denote instruction by means of the text of the Bible and of the exegetic deductions therefrom.
» actor-network theory Yesterday, Google introduced a new feature, which represents a substantial extension to how their search engine presents information and marks a significant departure from some of the principles that have underpinned their conceptual and technological approach since 1998. The “knowledge graph” basically adds a layer to the search engine that is based on formal knowledge modelling rather than word statistics (relevance measures) and link analysis (authority measures). As the title of the post on Google’s search blog aptly points out, the new features work by searching “things not strings”, because what they call the knowledge graph is simply a – very large – ontology, a formal description of objects in the world. Unfortunately, the roll-out is progressive and I have not yet been able to access the new features, but the descriptions, pictures, and video paint a rather clear picture of what product manager Johanna Wright calls the move “from an information engine to a knowledge engine”.
