The Awakening - Mécanique quantique du cerveau humain et la conscience «Times End Game Before reading this interesting and potentially life changing blog, it would be a good idea to watch the following short videos at the links provided below; and read the article, third link below, as a prerequisite if one does not understand the double slit experiment or basic quantum physics. Dr. All these refer to the elusive relationship between the body and the mind referred to more generally as the brain-mind problem. Psychology and related sciences were able to continue for many years by either ignoring the brain entirely or at best treating it as a black box whose rules of operation could be understood without reference to its internal contents or composition. The human brain without doubt is the most complex organ in the known universe. Consciousness on the other hand is neither physical nor biological. However, there are differences.

World’s First Perpetual Motion Machine? | ASTOUNDE.com Can this machine operate forever? Since at least the 12th century, man has sought to create a perpetual motion machine; a device that would continue working indefinitely without any external source of energy. A large scientific contingent thinks such a device would violate the laws of thermodynamics, and is thus impossible. Could it be that as a race, we don’t fully understand the laws of physics and such a device may indeed be possible? Norwegian artist and mathematician Reidar Finsrud is an outside the box thinker that has devised a machine that he believes achieves true perpetual motion. The dream is that if we’re able to produce perpetual motion machines, that we’d have tapped into the holy grail of sustainability: an infinite energy source. A device that requires no input to run that could be affixed to a generator would harvest free energy to power whatever we so pleased. What are your thoughts? Source: Finsrud Comments comments
Matières Vivantes | Physique, Biologie, évolution, et tout le reste … par Tom Roud Physicists Achieve Quantum Teleportation of Photon Over 25 Kilometers For the first time, a team of physicists have successfully teleported a quantum state of a photon to a crystal over 25 kilometers away through a fiber optic cable. This effectively showed that the photon’s quantum state, not its composition, is important to the teleportation process. The team was led by Nicolas Gisin of the University of Geneva and the results were published in the journal Nature Photonics. With this new paper, Gisin’s team has successfully squashed the previous record they set a decade ago by teleporting a quantum state of a proton 6 kilometers. The quantum state of the photon is able to preserve information under extreme conditions, including the difference between traveling as light or becoming stored in the crystal like matter. To test this and ensure what they were observing was actually happening, one photon was stored in a crystal while the other was sent along optical fiber, over a distance of 25 kilometers.
Mécanique quantique : nouvelle définition de la fonction d'onde - Fondamental La fonction d'onde de l'hydrogène (Wikimedia Commons) Un outil statistique et peut-être plus que ça En mécanique quantique, qui traite du comportement physique des particules atomiques et subatomiques, la fonction d’onde permet de calculer la densité de probabilité de présence d’une particule en certains points. En effet, à cette échelle, toute tentative de mesure influe directement sur la particule de sorte qu’il est impossible de connaître simultanément sa position et sa vitesse, c’est le fameux principe d’incertitude d’Heisenberg. Du coup, les mesures n'expriment pas des certitudes mais seulement des probabilités, représentées par la fonction d’onde. Pour les physiciens, la fonction d’onde est une abstraction mathématique et statistique qui permet de réduire, pas complètement, l’incertitude quantique. L’interprétation de Copenhague serait erronée Le débat sur la façon de comprendre la fonction d'onde remonte aux années 1920. Un «séisme» physique
Hawking Radiation Recreated In A Laboratory A researcher claims to have produced a simulation of Hawking radiation, which if true will give physicists the chance to test one of Stephen Hawking's most significant predictions. In 1974, Hawking upended ideas about black holes with his theory that just outside the event horizon, particle-antiparticle pairs should appear as a result of the black hole's gravitational field. One of these would be drawn into the hole, but the other escape. Since the appearance of the pair draws energy from the hole and only half of this is recaptured, the effect is to reduce the hole's mass, causing it to eventually evaporate. Hawking's equations have won widespread support from physicists, and are a major contributor to his reputation. Now Professor Jeff Steinhauer of the Technion-Israel Institute of Technology claims to be getting close. The fluctuations occur in pairs, modelling the particle-antiparticle pairs appearing around a black hole. Image CC BY-SA 2.5
Aperçu "Equation du tout...et information" When Parallel Worlds Collide . . . Quantum Mechanics Is Born Parallel universes – worlds where the dinosaur-killing asteroid never hit, or where Australia was colonised by the Portuguese – are a staple of science fiction. But are they real? In a radical paper published this week in Physical Review X, we (Dr Michael Hall and I from Griffith University and Dr Dirk-André Deckert from the University of California) propose not only that parallel universes are real, but that they are not quite parallel – they can “collide”. In our theory, the interaction between nearby worlds is the source of all of the bizarre features of quantum mechanics that are revealed by experiment. Many worlds in existing interpretations The existence of parallel worlds in quantum mechanics is not a new idea in itself – they are a feature of one of the leading interpretations of quantum mechanics, the 1957 “many worlds interpretation” (MWI). First, its formalism is extremely remote from everyday experience. Heads or tails? Many interacting worlds Implications and applications
Un monde sans temps ni espace Recensés : Carlo Rovelli, Quantum Gravity, Cambridge, Cambridge University Press, 2004 et Carlo Rovelli, Qu’est-ce que le temps ? Qu’est-ce que l’espace ?, Paris, Bernard Gilson Éditeur, 2008. Les entreprises scientifiques et épistémologiques, c’est un lieu commun, seraient avant tout des démarches de taxonomie. C’est très exactement en faux par rapport à ces schèmes fort répandus, que Carlo Rovelli s’inscrit dans ces deux ouvrages magistraux. Carlo Rovelli, éminent physicien théoricien et acteur majeur de la science contemporaine, est l’un des inventeurs de la gravitation quantique à boucles. La proposition est vertigineuse. La gravitation quantique à boucles [2] propose de considérer l’Univers comme une sorte de superposition de gigantesques réseaux abstraits (dits « de spin ») dont les nœuds constitueraient des « grains d’espace » et les arrêtes des relations de contiguïté entre ces grains. La quête d’unification a révélé son efficace.
Researchers at Brown University shattered an electron wave function A team of physicists based at Brown University has succeeded in shattering a quantum wave function. That near-mythical representation of indeterminate reality, in which an unmeasured particle is able to occupy many states simultaneously, can be dissected into many parts. This dissection, which is described this week in the Journal of Low Temperature Physics, has the potential to turn how we view the quantum world on its head. When we say some element of the quantum world occupies many states at once, what’s really being referred to is the element’s wave function. If a particle could be in position (x,y,z) in three-dimensional space, there are probabilities that it could specifically be at (x1,y1,z1) or (x2,y2,z2) and so forth, and this is represented in the wave function, which is all of these possibilities added together. Visually, we might imagine a particle in its undisturbed state looking more like a cloud than a point in space. Maris is chasing a fairly old mystery with this work.
Qu'est-ce que Quark Want to stay on top of all the space news? Follow @universetoday on Twitter Asking the right questions? (Image: CERN) It’s a Higgs boson. Right now, scientists have answered – or at least postulated the answer to – some very ponderous questions that lay just beyond the scope of the standard model. It should be easy, shouldn’t it? This lack of findings is causing some folks to wonder if we’re expecting answers to the wrong questions, but Rolf-Dieter Heuer, CERN’s director general is more optimistic.

Scientists Discover a Jewel at the Heart of Quantum Physics Physicists reported this week the discovery of a jewel-like geometric object that dramatically simplifies calculations of particle interactions and challenges the notion that space and time are fundamental components of reality. “This is completely new and very much simpler than anything that has been done before,” said Andrew Hodges, a mathematical physicist at Oxford University who has been following the work. The revelation that particle interactions, the most basic events in nature, may be consequences of geometry significantly advances a decades-long effort to reformulate quantum field theory, the body of laws describing elementary particles and their interactions. Interactions that were previously calculated with mathematical formulas thousands of terms long can now be described by computing the volume of the corresponding jewel-like “amplituhedron,” which yields an equivalent one-term expression. The amplituhedron itself does not describe gravity.
