Macroscopic quantum superpositions, a.k.a. the "many-worlds interpretation" or MWI, was proposed in 1957 and brought to the general attention of the scientific community in 1970. Ever since, MWI has steadily gained in popularity. As of 2008, MWI may or may not be endorsed by a majority of theoretical physicists (attempted opinion polls conflict on this point). Of course, Science is not supposed to be an opinion poll, but anyone who tells you that MWI is "science fiction" is simply ignorant. When a theory is slowly persuading scientists despite all academic inertia, and more and more graduate students grow up familiar with it, at what point should one go ahead and declare a temporary winner pending new evidence? Quantum Explanations: Quantum mechanics doesn't deserve its fearsome reputation. Quantum physicists show a small amount of randomness can be amplified without limit. Once again quantum physics gives us philosophical implications: physicists showed how a small amount of randomness can be amplified without limit.
Classical physics is deterministic: for example, we can determine the position and velocity of a particle at any time in the future. Quantum theory, on the other hand, states that there exist processes which are fundamentally random: for instance, the outcomes of measurements of quantum particles seem to be determined entirely by chance. - StumbleUpon. A Theory on the Deja Vu or Déjà vu Phenomenon During the time while this web-page has been on the Internet, more than three thousand people (up to Nov 2009) have e-mailed to say that they have Déjà Vu experiences.
That is interesting, but their descriptions have virtually always described some different phenomenon. If a person has any pre-knowledge of something that is yet to happen, like in a dream, it cannot be Déjà Vu, and is likely to be some type of Precognition. (Even if the Precognition is only a few seconds before the event.) A person cannot know that a Déjà Vu experience is coming, and also, it is also always sensed as INSTANTANEOUS, as being a sudden realization that an experience "was somehow familiar". This last part effectively eliminates credible Deja Vu from occurring in any place that the person has already been! Space Time Travel & Relativity Visualized. Physics Documents.

Cromie Gazette Staff "Two years ago we slowed it down to 38 miles an hour; now we've been able to park it then bring it back up to full speed. " Lene Hau isn't talking about a used motorbike, but about light – that ethereal, life-sustaining stuff that normally travels 93 million miles from the sun in about eight minutes. Less than five years ago, the speed of light was considered one of the universe's great constants. Albert Einstein theorized that light cannot travel faster than 186,282 miles per second. Hau, 41, a professor of physics at Harvard, admits that the famous genius would "probably be stunned" at the results of her experiments.
Lectures. Quantum Mechanics Explained. Quantum mysteries. John Gribbin For seventy years, physicists have worried about what quantum mechanics means.
They can use quantum physics, to be sure; witness the successful designs of lasers and computer microchips, and the understanding of molecules that makes genetic engineering possible. But the equations that are a routine part of this kind of work contain one embarrassing feature. The say, according to the standard interpretation (the Copenhagen interpretation), that nothing is real unless you look at it, that an electron (say) exists only as a wave of probability, called a wave function, which collapses into reality when it is measured, and promptly dissolves into unreality when you stop looking at it.
We are no further advanced philosophically, on this picture, than the image of the tree in the quad which disappears when nobody is looking at it. In fact, few physicists worry about such things. So far, simple enough. It works like this. Quantum Diaries. We’ve been discussing the Higgs (its interactions, its role in particle mass, and its vacuum expectation value) as part of our ongoing series on understanding the Standard Model with Feynman diagrams.
Now I’d like to take a post to discuss a very subtle feature of the Standard Model: its chiral structure and the meaning of “mass.” This post is a little bit different in character from the others, but it goes over some very subtle features of particle physics and I would really like to explain them carefully because they’re important for understanding the entire scaffolding of the Standard Model.
My goal is to explain the sense in which the Standard Model is “chiral” and what that means. In order to do this, we’ll first learn about a related idea, helicity, which is related to a particle’s spin. The Transactional Interpretation of Quantum Mechanics. John G.
Cramer This paper was originally published in Reviews of Modern Physics 58, 647-688, July (1986). Introduction to quantum mechanics. Many aspects of quantum mechanics are counterintuitive[3] and can seem paradoxical, because they describe behavior quite different from that seen at larger length scales. In the words of quantum physicist Richard Feynman, quantum mechanics deals with "nature as She is – absurd".[4] For example, the uncertainty principle of quantum mechanics means that the more closely one pins down one measurement (such as the position of a particle), the less accurate another measurement pertaining to the same particle (such as its momentum) must become.

A Lazy Layman's Guide to Quantum Physics. That's an easy one: it's the science of things so small that the quantum nature of reality has an effect. Quantum means 'discrete amount' or 'portion'.
Max Planck discovered in 1900 that you couldn't get smaller than a certain minimum amount of anything. The Strong Force for Beginners. “I found I could say things with color and shapes that I couldn’t say any other way — things I had no words for.” –Georgia O’Keeffe When it comes to the Universe, it isn’t just the stuff that’s in it that’s important. Image credit: 2MASS Extended Source Catalog (XSC). It’s also how all that stuff interacts with itself and everything else. To the best of our knowledge, there are four fundamental forces in the Universe, and they’re all essential to our existence.

Quantum Entanglement and Information (Stanford Encyclopedia of Philosophy) - StumbleUpon. First published Mon Aug 13, 2001; substantive revision Thu Aug 26, 2010 Quantum entanglement is a physical resource, like energy, associated with the peculiar nonclassical correlations that are possible between separated quantum systems.
Entanglement can be measured, transformed, and purified. A pair of quantum systems in an entangled state can be used as a quantum information channel to perform computational and cryptographic tasks that are impossible for classical systems.
