The CDF Collaboration blessed yesterday afternoon the results of a search for massive Gravitons decaying into pairs of Z bosons. And it is a startling new result! Usually after a blessing (which is…

The formulation of a fun physics problem with practical -and pleasant- applications occurred to me yesterday. I am currently spending a week in Madrid with my family, and we have chosen a very nice…

  Birefringence and the polarized light 1. Definition Birefringence is a kind of optical phenomenon that when the light go through an anisotropic crystals, there are two emergent refracted…

We are on. This afternoon just after 1PM the LHC beams have started to produce proton-proton collisions in the heart of the experiments, at the never-before achieved energy of 7 TeV. It was a long…

So how dangerous is the Large Hadron Collider? How likely is it that when operated at maximum energy the LHC will create a black hole and wipe out earth? Eric Johnson, assistant professor of law at…

Reflecting an interest that I've had for some time, that has been rekindled due to its inherent entanglement with my fundamental area of research  - the nature of time, I am releasing the first…

Scientists have discovered the world's smallest superconductor, a sheet of four pairs of (BETS)2GaCl4 molecules less than one nanometer wide. Their new Nature Nanotechnology study provides the first…

One of the original things that I've done in terms of reserach, has to do with super massive black holes and how they don't fit into a single reference frame from all points of view. I presented this…
