It bugs me a little when 'time' is randomly called a dimension in casual talk. Since just after Einstein's relativity, we've been treated to the mathematical idea that time is its own dimension -…

Just a small post to mention the recent activity in my Greek blog, where with the help of a very kind Greek student we are offering a selection of articles translated in Greek language. Here are the…

Most stories on the so called "accelerator on a chip" either fail to mention or deeply bury an important detail.     This device needs to be primed by a conventional accelerator.  …

In 1963, Roy Kerr's hypothesis was of a "clean" black hole model and that remains the dominant paradigm. From theory to reality things may be quite different, black holes may be much "dirtier" than…

A few days ago I posted the results of a poll ran on 50 or so participants to a workshop on the Higgs boson in Madrid. The poll consisted of six questions on the expectations one had on the…

UPDATE: Just found out that Peter Woit anticipated me on this - see his blog entry.--- Just five years ago, on the eve of the start of the Large Hadron Collider, most particle physicists -…

I have reported about the studies of resonances in the decays of the B+ meson by CDF, CMS, and LHCb a few times in the recent past. The situation, in a nutshell, was the following until yesterday:…

The ATLAS Collaboration published last week the results of a search for dark matter particles produced in association with a W or Z boson by the 8-TeV proton-proton collisions collected during the…

How to present in a simple way the spinorial space-time and the privileged space direction it generates? What is the fundamental difference between space-time spinors and the conventional description…

Researchers are reporting the first experimental determination of the weak charge of the proton, one of the four fundamental forces in our universe, along with gravity, electromagnetism and the…
