Brain simulates actions in stories as a person reads: study

What scientists discovered was that parts of the brain associated with certain activities described in the story would light up as the person read those sections.

This study suggests that readers do mental simulation when they comprehend a story,"

«Nous exposons notre cerveau à cet environnement et nous lui demandons de faire des choses qui ne font peut-être pas partie d'une évolution normale, résumait il y a quelques semaines le neurologue américain Adam Gazzaley, de l'Université de Californie, dans les pages du New York Times.

le mythe de l'humain multitâche et hautement productif avec son iPhone en main qui lui permet de suivre les cours de la Bourse, de programmer sa télévision à distance, de gérer sa bibliothèque musicale, de tenir à jour son agenda, d'informer ses amis de ses déplacements tout en téléchargeant des livres d'histoires à lire à ses enfants le soir avant de se coucher.

La technologie tend à reconfigurer les connexions du cerveau, mais elle est aussi contre-productive lorsqu'utilisée avec excès, estiment les chercheurs, et le fléau touche certainement la majorité des ménages dans les sociétés hautement numériques

Z-Wave is a wireless communications protocol designed for home automation, specifically to remotely control applications in residential and light commercial environments. The technology uses a low-power RF radio embedded or retrofitted into home electronics devices and systems, such as lighting, home access control, entertainment systems and household appliances.

Newton (unit) From Wikipedia, the free encyclopedia Jump to: navigation, search Not to be confused with Newton scale, a rarely used non-SI temperature scale. Newton Unit system: SI derived unit Unit of... Force Symbol: N Named after: Isaac Newton In SI base units: 1 N = 1 kg·m/s2 The newton (symbol: N) is the SI derived unit of force. It is named after Isaac Newton in recognition of his work on classical mechanics, specifically Newton's second law of motion.

Nombre figuré

un nombre entier qui peut être représenté par un ensemble de points disposés de façon plus ou moins régulière et formant une figure géométrique.

On attribue parfois à Pythagore les premières études de nombres figurés[1] (nombres carrés). Diophante a résolu plusieurs problèmes les concernant. Pascal a écrit un traité sur le sujet.

OpenLeaks

OpenLeaks is a project that aims at making whistleblowing safer and more widespread. This will be done by providing dedicated and generally free services to whistleblowers and organizations interested in transparency. We will also create a Knowledge Base aiming to provide a comprehensive reference to all areas surrounding whistleblowing.

Volt From Wikipedia, the free encyclopedia Jump to: navigation, search For other uses, see Volt (disambiguation). Josephson junction array chip developed by NIST as a standard volt The volt (symbol: V) is the SI derived unit for electric potential, electric potential difference, and electromotive force.[1] The volt is named in honor of the Italian physicist Alessandro Volta (1745–1827), who invented the voltaic pile, possibly the first chemical battery.

A single volt is defined as the difference in electric potential across a wire when an electric current of one ampere dissipates one watt of power.[

Second From Wikipedia, the free encyclopedia Jump to: navigation, search This article is about the unit of time. For other uses, see Second (disambiguation). A light flashing approximately once per second The second (SI unit symbol: s) is the International System of Units (SI) base unit of time[1] and also a unit of time in other systems (abbreviated s or sec[2]). Between 1000 (when al-Biruni used seconds) and 1960 the second was defined as 1/86,400 of a mean solar day (that definition still applies in some astronomical and legal contexts).[3][4] Between 1960 and 1967, it was defined in terms of the period of the Earth's orbit around the Sun,[5] but it is now defined more precisely in atomic terms. Seconds may be measured using mechanical, electric or atomic clocks.

Metre From Wikipedia, the free encyclopedia   (Redirected from Meter) Jump to: navigation, search This article is about the unit of length. For other uses of "metre" or "meter", see meter (disambiguation). 1 metre = SI units 100 cm 1000 mm US customary / Imperial units 3.2808 ft 39.370 in The metre (meter in the US), symbol m, is the base unit of length in the International System of Units (SI). Originally intended to be one ten-millionth of the distance from the Earth's equator to the North Pole (at sea level), its definition has been periodically refined to reflect growing knowledge of metrology. Since 1983, it has been defined as "the length of the path travelled by light in vacuum during a time interval of 1 ⁄ 299,792,458 of a second.[1]

Kilogram

The kilogram or kilogramme (SI symbol: kg), also known as the kilo, is the base unit of mass in the International System of Units and is defined as being equal to the mass of the International Prototype Kilogram (IPK), which is almost exactly equal to the mass of one liter of water. The avoirdupois (or international) pound, used in both the Imperial system and U.S. customary units, is defined as exactly 0.45359237 kg, making one kilogram approximately equal to 2.2046 avoirdupois pounds.

USS Lincoln VS canada This is the translation of the ACTUAL radio conversation of a U.S. naval ship with the Canadian authorities off the coast of Newfoundland. The Chief of Naval Operations on October 10th 1995 released the radio conversation. Canadians: Please divert your course 15 degrees to the South to avoid a collision. Americans: Recommend you divert your course 15 degrees to the North. Canadians: Negative. You will have to divert your course 15 degrees to the South to avoid a collision. Americans: This is the Captain of a US Navy ship. I say again, divert YOUR course. Canadians: No. I say again, you divert YOUR course. Americans: THIS IS THE AIRCRAFT CARRIER USS LINCOLN. THE SECOND LARGEST SHIP IN THE UNITED STATES ATLANTIC FLEET. THREE DESTROYERS, THREE CRUISERS AND NUMEROUS SUPPORT VESSELS ACCOMPANY US. I DEMAND THAT YOU CHANGE YOUR COURSE 15 DEGREES NORTH, I SAY AGAIN, THAT'S ONE FIVE DEGREES NORTH, OR COUNTERMEASURES WILL BE UNDERTAKEN TO ENSURE THE SAFETY OF THIS SHIP. Canadians: We are a lighthouse. Your call.

Coulomb

The coulomb (symbol: C) is the SI derived unit of electric charge. It is defined as the charge transported by a steady current of one ampere in one second: One coulomb is also the amount of excess charge on the positive side of a capacitance of one farad charged to a potential difference of one volt:
