"During the years 1962 to 1964 a debate developed about whether the Goldstone theorem could be evaded. Anderson pointed out that in a superconductor the Goldstone mode becomes a massive plasmon mode…

Inspired by my friend Peter Woit's openness in discussing his work in progress (a thick textbook on the foundations of quantum mechanics), I feel compelled to come out here about my own project. I…

I'm speaking of bare particles. "Heroes" is maybe too pathetic, but blocks or "bricks" would be OK since everything is made of them despite their being non-observable. Why are they non-observable?…

Just a quick link to allow you to browse a very nice set of pictures taken at CERN by Andri Pol. The subjects are physicists in their daily activities - brainstorming at the blackboard, cycling…

Last Tuesday I was in Mantova, a pleasant little town in northern Italy, rich of monuments and treasures like the Palazzo Ducale,  which hosts a vast collection of paintings and frescoes from…

"We haven't the foggiest idea what drives the new high-temperature superconductors, or what makes a snowflake, or how the mind or the economy works. What is more, nothing high energy physics can do…

Classical gravity is not good enough.  As a first step, one must think about groups since that is the foundation of the Standard Model of physics. All my failed efforts to think about gravity…

The top quark is the most massive elementary particle that we have so far discovered at particle accelerators. One usually describes this by saying that the top mass is about 185 times larger than…

I may today perhaps make the boldest claim I ever made, at least many will think so, and I am not known for my humbleness (though I should be – how many established scientists do see themselves as…

In a paper appeared a few days ago on the Cornell Arxiv Campbell, Ellis and Williams discuss how the LHC experiments have a chance to obtain information on the Higgs boson width by studying four-…
