Description of physical properties at the atomic and subatomic scale Quantum mechanics is a fundamental theory in physics that describes the behavior of nature at and below the scale of atoms.[2]: 1.1 It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science. Classical physics, the collection of theories that existed before the advent of quantum mechanics, describes many aspects of nature at an ordinary (macroscopic) scale, but is not sufficient for describing them at small (atomic and subatomic) scales.
Most theories in classical physics can be derived from quantum mechanics as an approximation valid at large (macroscopic) scale.[3] Overview and fundamental concepts Quantum mechanics allows the calculation of properties and behaviour of physical systems. A fundamental feature of the theory is that it usually cannot predict with certainty what will happen, but only give probabilities. . And , where Here. Physicists challenge classical world with quantum-mechanical implementation of 'shell game' Inspired by the popular confidence trick known as "shell game," researchers at UC Santa Barbara have demonstrated the ability to hide and shuffle "quantum-mechanical peas" -- microwave single photons -- under and between three microwave resonators, or "quantized shells.
" In a paper published in the Jan. 30 issue of the journal Nature Physics, UCSB researchers show the first demonstration of the coherent control of a multi-resonator architecture. This topic has been a holy grail among physicists studying photons at the quantum-mechanical level for more than a decade. The UCSB researchers are Matteo Mariantoni, postdoctoral fellow in the Department of Physics; Haohua Wang, postdoctoral fellow in physics; John Martinis, professor of physics; and Andrew Cleland, professor of physics. According to the paper, the "shell man," the researcher, makes use of two superconducting quantum bits (qubits) to move the photons -- particles of light -- between the resonators.

Infinity can always be divided up into ever increasing sets of infinities because of the continuous expansion at the quantum level. Uncertainty principle. Where ħ is the reduced Planck constant. The original heuristic argument that such a limit should exist was given by Heisenberg, after whom it is sometimes named the Heisenberg principle. This ascribes the uncertainty in the measurable quantities to the jolt-like disturbance triggered by the act of observation. Though widely repeated in textbooks, this physical argument is now known to be fundamentally misleading.[4][5] While the act of measurement does lead to uncertainty, the loss of precision is less than that predicted by Heisenberg's argument; the formal mathematical result remains valid, however.
Since the uncertainty principle is such a basic result in quantum mechanics, typical experiments in quantum mechanics routinely observe aspects of it. Certain experiments, however, may deliberately test a particular form of the uncertainty principle as part of their main research program. Introduction[edit] Click to see animation.

With yields where. 8 shocking things we learned from Stephen Hawking's book. From the idea that our universe is one among many, to the revelation that mathematician Pythagoras didn't actually invent the Pythagorean theorem, here are eight shocking things we learned from reading physicist Stephen Hawking's new book, "The Grand Design," written with fellow physicist Leonard Mlodinow of Caltech. The book, covering major questions about the nature and origin of the universe, was released Sept. 7 by its publisher, Bantam. 1. The past is possibility According to Hawking and Mlodinow, one consequence of the theory of quantum mechanics is that events in the past that were not directly observed did not happen in a definite way. Instead they happened in all possible ways. For example, if all we know is that a particle traveled from point A to point B, then it is not true that the particle took a definite path and we just don't know what it is.
Yeah, we're still trying to wrap our brains around this. 2. Photons are the little packets that light comes in. 3. 4. 5. 6. 7. 8. Tsipise. Writing. Will you perceive the event that kills you? David Eagleman is guest blogging this week. When light strikes your eyes, it takes some hundreds of milliseconds before you become conscious of the event. As a consequence, you are always living in the past. This strange fact of our existence is well known is neuroscience, but there’s an interesting, underappreciated consequence: you may not ever become aware of the thing that kills you. Cormac McCarthy addresses this point in his post-apocalyptic novel The Road, in a scene in which the main character has his pistol leveled on a miscreant. The malefactor challenges: “you won't shoot....they [my companions] will hear the shot.”
The protagonist replies, “Yes they will. “How do you figure that?” “Because the bullet travels faster than sound. One way to appreciate the slowness of your perception is to compare it to the speed of mechanical devices. 15 ms - Roof begins to absorb part of the impact. The last line is the zinger. David Eagleman is a neuroscientist and a writer. Nanotube yarn makes self-cleaning clothes that are also batteries. By turning powders into fibers using carbon nanotube webs, researchers at the University of Texas have managed to make yarn that can clean itself and work as a battery.
It also happens to be a superconductor, but most importantly, it's machine-washable. You may not think about it, but a lot of the cool technologies that we depend on every day rely on powders to work. Lithium ion batteries, for example, use a fine powder with a huge surface area as an electrode to store energy. This is great, except powders are messy, and you can't really use them in non-rigid applications. One way to get around this problem is to use nanotubes, those magical carbon structures that are capable of just about anything.
The upshot of this technique is that you can make yourself a piece of fabric that is, for all intents and purposes, one giant battery.

Arthur Schopenhauer (1788-1860), was a brilliant German philosopher. These 38 Stratagems are excerpts from "The Art of Controversy", first translated into English and published in 1896. Carry your opponent's proposition beyond its natural limits; exaggerate it. The more general your opponent's statement becomes, the more objections you can find against it. The more restricted and narrow his or her propositions remain, the easier they are to defend by him or her.
Use different meanings of your opponent's words to refute his or her argument. Ignore your opponent's proposition, which was intended to refer to a particular thing. (abstracted from the book:Numerical Lists You Never Knew or Once Knew and Probably Forget, by: John Boswell and Dan Starer)
