2013/03/26 > BE France 279 > Vers l'émergence de transistors en 3D En direct des laboratoiresVers l'émergence de transistors en 3D Brique de base de la microélectronique, le transistor se présente sous la forme d'un élément semi-conducteur, dit "canal", reliant deux bornes. Le passage d'un courant entre celles-ci est contrôlé par une troisième borne que l'on appelle la grille, véritable interrupteur déterminant l'ouverture et la fermeture du transistor. Si la taille des transistors n'a cessé de se réduire au cours des décennies passées, leur miniaturisation semble atteindre aujourd'hui des limites avec ce modèle d'architecture planaire. D'où les alternatives explorées par les chercheurs du monde entier afin de poursuivre cette miniaturisation.

The Century of the Self – The Rise of the All-Consuming Self and the Influence of the Freud Dynasty Edward Bernays invented ‘Public Relations' in the 1920s, being the first person to take Freud's ideas to manipulate the masses. He showed American corporations how they could make people want things they didn't need by systematically linking mass-produced goods to their unconscious desires. “If we understand the mechanism and motives of the group mind, it is now possible to control and regiment the masses according to our will without them knowing it.” Edward Bernays – also known as the “father of propaganda” – took Freud's key thesis that individuals were driven by unconscious irrational forces and used it to develop marketing techniques which are now common place. One example was Bernays campaign to convince women to smoke in the 1920s. Bernays used psychoanalysis to associate the act of smoking with a sort of challenge to male sexual power. After the historical public event, women started lighting up more than ever before. Related Posts
Future Trends Future Trends When faced with fresh challenges and the opportunities and threats posed by technological innovation, the human race has always evolved to live, work and explore in new ways. Listed below are some of those rising social, industrial and organizational phenomenon that look set to trigger many changes in our lives and belief systems over the coming decades. Please note that trends specifically linked to particular technologies and their development are included here in the future technologies section. More Local Living Due to Peak Oil and wider resource depletion, within a few decades it is going to be impossible to trade globally in most foods and many basic goods. Low Energy Lifestyles The 'net energy' output of all alternative energy sources is far lower than that of petroleum. Crowdsourcing The Internet offers the opportunity to help us collectively solve problems and develop products in new ways. Dematerialization Design for Repair Vertical Farming Life Extension
À 15 ans, elle invente une source de lumière inépuisable Ann Makosinski, une jeune canadienne de 15 ans a inventé une lampe fonctionnant grâce à l’énergie émise par la chaleur du corps humain. Ann Makosinski a inventé un objet révolutionnaire : une lampe-torche alimentée uniquement par la chaleur corporelle de la paume de la main. Appelée Hallow Flashlight, cette lampe de poche fonctionne en utilisant le principe de l’effet Peltier. C’est un principe physique qui veut que l’on puisse créer de l’énergie en utilisant les déplacements de chaleur sur des morceaux de métal conducteurs. Ainsi, elle explique : « Il y a plusieurs paires de ces deux métaux prises en sandwich entre deux plaques de céramique. La Hollow Flashlight peut rester allumée pendant au moins 20 minutes grâce à la chaleur de votre main, précisant qu’elle n’a pas encore fait de test au-delà de cette durée. Si vous souhaitez encourager Ann, vous pouvez aller sur ce site dédié au concours du Google Science Fair. Sources : Dailygeekshow / Le JDS Like this: J'aime chargement…
