Einstein's hope for a purely algebraic theory[edit]The Bohm interpretation of quantum mechanics hypothesizes that the state of the universe evolves smoothly through time with no collapsing of quantum wavefunctions. One problem for the Copenhagen interpretation is to precisely define wavefunction collapse. Einstein maintained that quantum mechanics is physically incomplete and logically unsatisfactory. In "The Meaning of Relativity," Einstein wrote, "One can give good reasons why reality cannot at all be represented by a continuous field. From the quantum phenomena it appears to follow with certainty that a finite system of finite energy can be completely described by a finite set of numbers (quantum numbers). This does not seem to be in accordance with a continuum theory and must lead to an attempt to find a purely algebraic theory for the representation of reality. But nobody knows how to find the basis for such a theory." If time, space, and energy are secondary features derived from a substrate below the Planck scale, then Einstein's hypothetical algebraic system might resolve the EPR paradox (although Bell's theorem would still be valid). Edward Fredkin in the Fredkin Finite Nature Hypothesis has suggested an informational basis for Einstein's hypothetical algebraic system. If physical reality is totally finite, then the Copenhagen interpretation might be an approximation to an information processing system below the Planck scale.

Acceptable theories" and the experiment[edit]According to the present view of the situation, quantum mechanics flatly contradicts Einstein's philosophical postulate that any acceptable physical theory must fulfill "local realism".
In the EPR paper (1935) the authors realised that quantum mechanics was inconsistent with their assumptions, but Einstein nevertheless thought that quantum mechanics might simply be augmented by hidden variables (i.e. variables which were, at that point, still obscure to him), without any other change, to achieve an acceptable theory. He pursued these ideas for over twenty years until the end of his life, in 1955. In contrast, John Bell, in his 1964 paper, showed that quantum mechanics and the class of hidden variable theories Einstein favored[17] would lead to different experimental results: different by a factor of 3⁄2 for certain correlations. So the issue of "acceptability", up to that time mainly concerning theory, finally became experimentally decidable. There are many Bell test experiments, e.g. those of Alain Aspect and others. They support the predictions of quantum mechanics rather than the class of hidden variable theories supported by Einstein.[2] According to Karl Popper these experiments showed that the class of "hidden variables" Einstein believed in is erroneous.[

Standard quantum mechanics can be approached in three different ways: the matrix mechanics, the SchrÃ¶dinger equation and the Feynman path integral.
The Feynman path integral[2] is the path integral over Brownianlike quantummechanical paths. Fractional quantum mechanics has been discovered by Nick Laskin (1999) as a result of expanding the Feynman path integral, from the Brownianlike to the LÃ©vylike quantum mechanical paths. A path integral over the LÃ©vylike quantummechanical paths results in a generalization of quantum mechanics.[3] If the Feynman path integral leads to the well known SchrÃ¶dinger equation, then the path integral over LÃ©vy trajectories leads to the fractional SchrÃ¶dinger equation.[4] The LÃ©vy process is characterized by the LÃ©vy index α, 0 < α ≤ 2. At the special case when α = 2 the LÃ©vy process becomes the process of Brownian motion. The fractional SchrÃ¶dinger equation includes a space derivative of fractional order α instead of the second order (α = 2) space derivative in the standard SchrÃ¶dinger equation. Thus, the fractional SchrÃ¶dinger equation is a fractional differential equation in accordance with modern terminology.[5] This is the main point of the term fractional SchrÃ¶dinger equation or a more general term fractional quantum mechanics. As mentioned above, at α = 2 the LÃ©vy motion becomes Brownian motion. Thus, fractional quantum mechanics includes standard quantum mechanics as a particular case at α = 2. The quantummechanical path integral over the LÃ©vy paths at α = 2 becomes the wellknown Feynman path integral and the fractional SchrÃ¶dinger equation becomes the wellknown SchrÃ¶dinger equation.

Usually quantum mechanics deals with matter on the scale of atoms and atomic particles. However, at low temperatures, there are phenomena that are manifestations of quantum mechanics on a macroscopic scale, the bestknown being superfluidity and superconductivity.
Between 1996 to 2003 four Nobel prizes were given for work related to macroscopic quantum phenomena.[1] Macroscopic quantum phenomena can be observed in superfluid helium and in superconductors,[2] but also in dilute quantum gases and in laser light. Although these media are very different, their behavior is very similar as they all show macroscopic quantum behavior. Quantum phenomena are generally classified as macroscopic when the quantum states are occupied by a large number of particles (typically Avogadro's number) or the quantum states involved are macroscopic in size (up to km size in superconducting wires).

WASHINGTON (The Borowitz Report)Â—In an impressive whiteknuckle performance on live television today, members of Congress spent several hours in a hearing room pretending to understand the Internet.
Beginning this morning, members of the House Energy and Commerce Committee devoted four hours to grilling Website contractors about site architecture, Web traffic, software, and other I.T. concepts about which their ignorance is nearly complete. Â“As members of this committee, we are supposed to have a deep understanding of the technology involved in the healthcare Web site,Â” said Chairman Fred Upton (RMichigan).Â“So it was absolutely imperative for us to fake that we do.Â” For the duration of the hearings, the Web contractors offered detailed testimony about Â“endtoend testing,Â”Â“enterprise identity management,Â” and other technical concepts to a group of elected officials who can barely use email. Â“I would say that, to a man, we did not understand ninetynine per cent of that computer nonsense they were going on about,Â” Chairman Upton said.Â“To me it was a whole lot of blahbittyblahbittyblah. I hope it wasnÂ’t too obvious.Â” Rep. Upton said that Â“looking serious and nodding our heads a lotÂ” contributed to the illusion that committee members had even scant comprehension of what was being discussed. At the end of the day, a lot of it came down to not asking the questions you really wanted to ask,Â” he said.Â“Like,Â‘What exactly is a Web site?Â’Â”

Really? " Factcheck.org and the Kaiser Family Foundation have breakdowns of the RyanÂ’s Â“Path To ProsperityÂ” plan from March 2012." Under RyanÂ’s plan, beginning in 2023, people over 65 would pick an insurance plan in a new Medicare exchange system, with Medicare competing with other insurers for their business. The government would send money, called a premiumsupport payment, directly to the insurer picked by the consumer. If the consumer picks a plan more expensive than the government premium payment they receive, the consumer must pay the difference out of pocket. If the consumer picks a cheaper plan, they pocket the difference in the form of a rebate check. The Ryan plan set the premium payment to consumers at the cost of the secondleast expensive governmentapproved plan. The federal government will determine the minimum level of benefits that all plans must offer. The premiumsupport payment is capped at the growth of GDP, plus 0.5 percent. The subsidy will be adjusted based on the income level of the consumer. After 2022, seniors are guaranteed they can enroll in any plan offered by the new exchanges and Medicare despite their health status or age. In RyanÂ’s March 2012 plan, there is no limit of outofpocket costs incurred by seniors, and the plan doesnÂ’t address prescription drug costs." Now, what's different about Ryans' plan for Seniors and the Affordable Care Act? http://news.yahoo.com/understandingpaulryan...

The physical interpretation of the quantity
(15) depends on the number of particles. Fig.1 represents a container with a certain number of particles with a small control volume ΔV inside. We check from time to time how many particles are in the control box. We distinguish three cases: 1. There is only one particle. In this case the control volume is empty most of the time. However, there is a certain chance to find the particle in it given by Eq.(15). The chance is proportional to ΔV. The factor ΨΨ∗ ; is called the chance density. 2. If the number of particles is a bit larger there are usually some particles inside the box. We can define an average, but the actual number of particles in the box has relatively large fluctuations around this average. 3. In the case of a very large number of particles there will always be a lot of particles in the small box. The number will fluctuate but the fluctuations around the average are relatively small. The average number is proportional to ΔV and ΨΨ∗ ; is now interpreted as the particle density. In quantum mechanics the particle probability flow density Jp (unit: particles per second per mÂ²) can be derived from the SchrÃ¶dinger equation to be

The phase space formulation of quantum mechanics places the position and momentum variables on equal footing, in phase space. In contrast, the SchrÃ¶dinger picture uses the position or momentum representations (see also position and momentum space). The two key features of the phase space formulation are that the quantum state is described by a quasiprobability distribution (instead of a wave function, state vector, or density matrix) and operator multiplication is replaced by a star product.
The theory was fully detailed by Hip Groenewold in 1946 in his PhD thesis,[1] with significant parallel contributions by Joe Moyal,[2] each building off earlier ideas by Hermann Weyl[3] and Eugene Wigner.[4] The chief advantage of the phase space formulation is that it makes quantum mechanics appear as similar to Hamiltonian mechanics as possible by avoiding the operator formalism, thereby "'freeing' the quantization of the 'burden' of the Hilbert space."[5] This formulation is statistical in nature and offers logical connections between quantum mechanics and classical statistical mechanics, enabling a natural comparison between the two (cf. classical limit). Quantum mechanics in phase space is often favored in certain quantum optics applications (see optical phase space), or in the study of decoherence and a range of specialized technical problems, though otherwise the formalism is less commonly employed in practical situations.[6] The conceptual ideas underlying the development of quantum mechanics in phase space have branched into mathematical offshoots such as deformation theory (cf. Kontsevich quantization formula) and noncommutative geometry.

Main articles: Quasiprobability distribution, Wigner quasiprobability distribution, and WignerÂ–Weyl transform
The phase space distribution f(x,p) of a quantum state is a quasiprobability distribution. In the phase space formulation, the phasespace distribution may be treated as the fundamental, primitive description of the quantum system, without any reference to wave functions or density matrices.[7] There are several different ways to represent the distribution, all interrelated.[8][9] The most noteworthy is the Wigner representation, W(x,p), discovered first.[4] Other representations (in approximately descending order of prevalence in the literature) include the GlauberSudarshan P,[10][11] Husimi Q,[12] KirkwoodRihaczek, Mehta, Rivier, and BornJordan representations.[13][14] These alternatives are most useful when the Hamiltonian takes a particular form, such as normal order for the GlauberÂ–Sudarshan Prepresentation. Since the Wigner representation is the most common, this article will usually stick to it, unless otherwise specified. The phase space distribution possesses properties akin to the probability density in a 2ndimensional phase space. For example, it is realvalued, unlike the generally complexvalued wave function. We can understand the probability of lying within a position interval, for example, by integrating the Wigner function over all momenta and over the position interval:

like you molesting a child A point of caution, however: despite the similarity in appearance, W(x,p) is not a genuine joint probability distribution, because regions under it do not represent mutually exclusive states, as required in the third axiom of probability theory. Moreover, it can, in general, take negative values even for pure states, with the unique exception of (optionally squeezed) coherent states, in violation of the first axiom. Regions of such negative value are provable to be "small": they cannot extend to compact regions larger than a few ħ, and hence disappear in the classical limit. They are shielded by the uncertainty principle, which does not allow precise localization within phasespace regions smaller than ħ, and thus renders such "negative probabilities" less paradoxical. If the left side of the equation is to be interpreted as an expectation value in the Hilbert space with respect to an operator, then in the context of quantum optics this equation is known as the optical equivalence theorem.(For details on the properties and interpretation of the Wigner function, see its main article.)
