I use Standalone Compiz with Xfdesktop to manage the desktop. Compiz is is actually fast and lightweight because your 3D viedo card does all the heavy lifting. It actually consumes no more memory than most 2D window Managers'. I have been using GLX-Dock which like Avant has an OSX look and feel:

Motl may be brilliant mathematically but he is a prejudiced paranoid whose dubious behaviour into trying con arXiv into censoring scientists he disagreed resulted in his "resignation" (aka firing) from his post at Harvard.

<quote><p> the idea that un-entangled states would be able to communicate with one another is a bit more problematic than the idea that entangled states would be able to communicate with one another.</p></quote>

I imagine Valentini would have an explanation. In fact he has argued that something similar should occur as remnants of entanglements from the early universe before matter became close to equilibrium and the quasi-classical domain emerged and that should give rise to non-local effects potentially observable today. OK it is due to entanglements but not to recent experimentally prepared entanglements as in EPR ad the Bell theorem.

Einstein and Schr&#246;dinger also regarded the Copenhagen solution as effectively superstitious and nonsense. Bohr and Heisenberg won that round but they are loosing now, this paper shows that the Copenhagen interpretation is of necessity non-local something Einstein tried to prove with the EPR thought experiment. David Bohm and his supporters were prepared to loose locality to provide a hidden variables/quantum potential alternative to the Copenhagen interpretation, however I doubt the supporters of the Copenhagen interpretation and its modern variants are about to embrace non-locality.

Everett and quantum reality rules.

Yes one of the implications of this paper is that if we are to have a local theory of QM consistent with relativity is that then Everett and the many-worlds interpretation of QM is right. Hilbert space then becomes real, not just a mathematical vector space, and is filled with orthogonal real worlds with each world as real as any other.

I read the preprint over the weekend after I saw a reference to it on Cosmic Variance. The implications of it are still just beginning to sink in.

Bee the German theoretical physicist at the Perimeter Institute here in Canada has a recent post about scientific tattoos on her blog Backreaction. It includes to nice photos of scientists with scientific tattoos on their arms:

I have for the last twenty years have been trying to persuade myself into getting a tattoo of Schrodingers wave equation, someday I will, or maybe not.

The Java based music player / organizer aTunes is fully cross platform and is in many ways comparable to Songbird in features.

MS is probably paying them back more in some other related deal in order to pay I/O Data for joining in the FUD campaign the way they bought all the others who "paid" for MS licenses on unsupported patent claims against Linux

It is not particularity Windows like. It is just a standard KDE 3.5 desktop using the crystal icon set with a few new icons like the red star for the start menu icon. The file browser is Konqueror. Nothing new here. No special effort to make it look like Widows.

Yet again someone who just doesn't get what QM shows.

The evolution of the State Vector is unitary and therefore deterministic. That is a consequence of unitarity, as all the probabilities must add up to one. Any quantum experiment you perform can only return a probabilistic result. This is independent of whatever interpretation of QM you prefer and is not dependent on the Copenhagen Interpretation.

Einstein did not like the elimination of determinism from physical theory and believed a theory showing hidden variables that would establish determinism might be developed. He and his co-workers Podolsky and Rosen (EPR) developed a thought experiment designed to act as a reductio ad absurdum of a non-deterministic QM.

Von Neumann provided a mathematical proof that eliminated all local hidden variables theories of QM. Einstein disliked non-local deterministic theories of QM more than non-deterministic ones as the principle of locality is essential to relativity.

Later it was realized that the EPR thought experiment could be developed into a real experimental test of QM via the Bell inequality. Experiments have been carried out with QM confirmed and Einstein proved wrong. Hidden variable theories that restore determinism have been shown to be impossible.

The physical world we live in is fundamentally stochastic and it is one of the consequences of QM.
