One more view at Italy's escape of brains

Jan 15 2014 | comment(s)

In Italy the debate over the escape of brilliant young scientists to foreign countries has been going on for decades now. Italians like to debate, much less to solve their own problems. So although the problem is clearly identified and a recipe to solve it is evident, nobody does anything to implement the solution. Which, of course, would be to raise salaries to researchers and allow for quicker and easier ways to access a career for young post-docs.

Aitzaz, 14 Years, Hero

Jan 10 2014 | comment(s)

The 14 year old kid in the picture on the right was named Aitzaz Hasan Bangash. His name is a difficult one to remember for westerners, but that is a pity, because he ended his life as a true hero.

Last Monday Aitzaz was lingering out of school with two friends in the small shiite town of Ibrahimzai, near the Pakistani capital Islamabad. Just before getting in they were approached by a 20-year-old who claimed he wanted to enrol to the school. The students realized that he was concealing a bomb and planned to blow up the school.

The Quote Of The Week - The Nonsensical Hypothesis Of Quarks

Jan 09 2014 | comment(s)

At the 1962 Rochester conference in Geneva, the prediction that a particle later called the Omega minus should exist, already proposed in a paper by Glashow and Sakurai, was not considered important enough to be mentioned in any invited or contributed talk. It was mentioned in a comment from the floor by Gell-Mann. The paper proposing the existence of quarks was accepted by Physics Letters only because it had Gell-Mann's name on it. The editor said, "The paper looks crazy, but if I accept it and it is nonsense, everyone will blame Gell-Mann and not Physics Letters. If I reject it and it turns out to be right, I will be ridiculed."

The Sacred Sword - Radioactive Contamination At Fermilab In 1986

Jan 07 2014 | comment(s)

In a guest post written three years ago Giorgio Chiarelli told us the story of how the CDF detector saw its first proton-antiproton collisions, during the night of October 13th 1985. It was a very important moment for the history of the collaboration, the start of a data collection campaign that would last over a quarter of a century. Below I wish to tell you the story of one of the worst radiological incidents in the history of the experiment, which happened a few months after those first collisions were recorded.

Two Papers By DZERO On Jet Physics

Dec 31 2013 | comment(s)

The DZERO experiment is one of the two multi-purpose detectors that have collected 1.96 TeV proton-antiproton collisions at the Fermilab Tevatron collider until two years ago, when the machine was decommissioned.

Experiments of this kind out-live the demise of the hardware, since the extraction of precise physics measurements from the large datasets accumulated may take several years to complete. And in fact, it is not a surprise to see two new preprints in the Arxiv (here and here) which describe in detail the experimental techniques that the collaboration uses to extract jet physics results from the data.

Highlights From A Chess Tournament

Dec 24 2013 | comment(s)

The XVIth international chess tournament "Citta' di Padova" ended last Sunday with the victory of GM Kiril Georgiev, who got 7 points out of 9 games. The tournament saw the participation of 63 players from 13 countries, with a total of 11 grandmasters and 13 international masters, plus nine other Fide titled players.

I participated in the event and scored a good 4.5/9, winning four games and losing four. Below I am showing some salient points from a few of my games.
