"I learned the stopping-rule principle from Professor Barnard in conversation in the summer of 1952. Frankly, I then thought it a scandal that anyone in the profession could advance an idea so…

Effect of embedding Fe3O4 nanoparticles in silica spheres on the optical transmission properties of three-dimensional magnetic photonic crystals Magnetic and optical properties of three-dimensional…

I am very happy to report here (after having done the same on my Greek blog first, for a change) that the "Max Planck" medal for 2011 has been assigned to Giorgio Parisi, a distinguished Italian…

In another thread on Science 2.0 we got onto the nature of existence and what we can say for certain about the universe (if anything).  Given that physics and math seem so intimately linked in…

At the Edge you can find a rather interesting discussion between Lee Smolin and Leonard Susskind, involving all the stuff I try to demystify often. They fought via email, then agreed to each write a…

A really interesting piece of news comes from the CERN laboratory today. The CMS experiment has detected a handful of Z boson decays in events featuring the collision between heavy ions, accelerated…

Atoms of antimatter have been trapped and stored for the first time by the ALPHA collaboration, an international team of scientists working at CERN.  ALPHA stored atoms of antihydrogen,…

The DZERO collaboration  published a few days ago the results of their search for multi-b-quark signatures of Supersymmetry in a large dataset of proton-antiproton collisions at 1.96 TeV. The…
