Today I wish to briefly discuss a recent important measurement produced by the LHCb collaboration, a measurement of CP violation in the decay of charmed mesons. Before I do, I think I need to explain…

A list of eleven steps to analyzing an action will be presented. I could have added one more, but then people might think I was giving up on my physics addiction. The method will be applied to Newton…

In 2011, science has been confronted with several high profile awkward situations of having to explain why standard methods like classical significance analysis are acceptable in for example medical…

Physicists have succeeded in taking a decisive step towards the development of more powerful computers; they were able to define two little quantum dots (QDs), occupied with electrons, in a…

UHFF stands for Ultra-High Field Facility. The project is at times confused with the Extreme Light Infrastructure (ELI), which includes three other experiments apart from UHFF. The total bill is $1.6…

Gauge symmetry is a clear, direct idea in EM, as I will detail. This property is essential, [correction: due to redundancy found in the 4-potential description of light and not any issue of the speed…

I would like to signal an interesting article I have found on the web: Brian Cox is wrong: blogging your research is not a recipe for disaster - by Sarah Kendrew I tend to agree with Sarah, but I…

Neutrinos were first postulated in 1930 by Wolfgang Pauli, who won the 1945 Nobel Prize in Physics. “I have done something very bad today by proposing a particle that cannot be detected,” Pauli wrote…

These days I am preparing a three-hour course of statistics for particle physicists which I will give at a winter school in a couple of months. This stimulating task forces me to find nice and simple…

My recent article  on the relationship between Einstein's Theory of Relativity and superluminal neutrinos has triggered a series of comments. Some of them were reasonable, some others not. Among…
