Physics

Twitter and Facebook have been studied extensively and have provided some insights into the formation and maintenance of human social networks. But could this approach be adapted to gain…

In the beautiful hideout of Falassarna, Crete (see below), I am blogging today from the terrace of my hotel room, overlooking a wonderful beach. Although still "connected" and in touch with the…

Consider the following scenario. An initial measurement indicates that two indistinguishable particles – particles of the same type, carrying no kind of identity tag – are headed northward and…

I was waiting for the announcement in the Fermilab seminar of next Friday, but apparently despite I am still a member I am not well enough informed of what happens inside CDF, the experiment at the…

Julian Barbour is an independent theoretical physicist who has gained some attention of late. Minkowski is dead. From my soapbox here, I will channel Minkowski in this gentlemen’s disagreement. Links…

The Many Worlds Wiener Sausage is the first step in understanding the Einstein-Podolsky-Rosen (EPR) paradox. However, there are still three steps missing until we can resolve the EPR paradox…

While other sources (voluntarily not linked here, to avoid pissing off my collaborators) choose to be "on the news" these days, with a brand new exclusion plot of the Higgs boson obtained using…

This instance of my "guess the plot" contest will be hopefully raising fewer controversies than the former one. You are asked to explain what the figure represents, possibly guessing the units on the…

This just to report progress on the Quantum Randi Challenge. It has changed a lot, so please have a look to see whether you think it is now attractive enough for you to help “internetizing” it, which…

The game of quantum mechanics is rigged, but I will let you in on the rules. The wave function has all the information usually written as complex values. Operators are used to grab out different…
