Le sifflement de la locomotive à vapeur. Le picotement de la machine à coudre. La mélodie robotique du modem. Ces sons qui ont défini à leur manière leur époque sont aujourd'hui en voie de disparition. Saurez-vous les reconnaître ?
En effet, des pays comme le Danemark étudient la possibilité de supprimer le cash. D’autres comme la France, la Belgique ou l’Espagne interdisent déjà les transactions en cash au-delà d’un certain montant. Et des banques américaines comme JP Morgan ont interdit à leurs clients de déposer des espèces dans les coffres qu’ils louent. Mais cela, ce n’est que la partie émergée de l’iceberg.
Skype a intégré en beta une fonctionnalité baptisée Skype Translator qui permet de traduire en temps réel, tout ce que vous dites, dans une autre langue.
How it works
Speak another language without learning another language. Simply set up a Skype video or voice call with someone who speaks another language to you and start talking.
✔ Your conversation is translated into their language in real time.
✔ And what they say is translated back in your language.
✔ An on-screen transcript of your call is displayed.
✔ Instant message chats in 45 languages can be translated.
In order for humans to live in outer space, they must have a steady supply of oxygen they can depend on. Now, instead of relying on plants that may not survive, they can use an artificial biological leaf designed by a London graduate student.
http://en.wikipedia.org/wiki/EmDrive
EmDrive (also Relativity Drive) is the name of a spacecraft propulsion system proposed by British aerospace engineer Roger J. Shawyer, who develops prototypes at Satellite Propulsion Research Ltd (SPR),[1] the company he created for that purpose in 2000.[2] New Scientist ran a cover story on EmDrive in its 8 September 2006 issue.[3] The device uses a magnetron producing microwaves directed inside a specially shaped, fully enclosed tapering high Q resonant cavity whose area is greater at one end, upon which radiation pressure would act differently due to a relativistic effect caused by the action of group velocity in different frames of reference. The inventor claims that the device generates a thrust even though no detectable energy leaves the device. If proven to work as claimed, the EmDrive could allow the design of spacecraft engines that would be electrically powered and would require no reaction mass. Such an engine would be a breakthrough in airflight and spaceflight.
