Many Worlds by Splitting a Wiener Sausage is extremely simple as far as models go. Before we can resolve the Einstein-Podolsky-Rosen paradox with it however, we need to understand what is still wrong…

The DZERO collaboration has just produced an update of their analysis of the dimuon charge asymmetry using 9.0 inverse femtobarns of proton-antiproton collisions. The new result confirms the…

In their seminal paper of 1935, Einstein, Podolsky, and Rosen (EPR) put forward the following criterion, which they considered reasonable: If, without in any way disturbing a system, we can predict…

A few years back I heard Joy Christian give a talk on his disproof of Bell's theorem, where he explained his idea for an experiment involving two hemispheres with a mass stuck on each. To me it…

I am quite happy today to announce here that there is a new blog to visit, and to bookmark!, for those among you who are interested to know what does a PhD in physics do after he or she graduates. In…

I think of myself as non-violent, a purple guy in the blue state of Massachusetts.When it comes to proposals in science though, I go for head shots. Nature doesn’t care if we keep repackaging…

I feel quite grateful to the DZERO collaboration for publishing today in the Cornell arxiv the preprint of their search for neutral MSSM Higgs bosons in the tau-pair decay mode. Not more than 12…

This recent Nature article makes people jump up and down in classical, non-quantum jumps as we speak: “Experimental non-classicality of an indivisible quantum system”. There are plenty of misleading…

Quantum entanglement was strange when it was conceptualized.   It violated Einstein's famous speed limit in his Theory of Relativity and he called it spukhafte Fernwirkung - “spooky action at a…

Continued from the last post. Discounting the Bohmian song and dance, we are led to conclude that each electron does in some sense pass through both slits. But in what sense? Saying that an electron…
