My Top 10 Particle Physics Articles Of 2011

Dec 31 2011 | comment(s)

A blog is by nature a place where things move on fast. Articles disappear beyond the horizon in the matter of a week or two, and only rarely get resuscitated by a later article linking them back from oblivion.

At Science 2.0 things are no better than in any other blog sites, with the aggravating feature that there is no "archive" button, nor a "random post" feature. Since I believe that many of my articles are not very connected to the specific time at which they have been written, I have in mind to reorganize the material somehow, when I have the time. However, this looks like a grievious task, since the number of posts I have written here is about 500.

The Say Of The Week - Heinrich on Coverage

"Exact coverage, like the Grail of legend, if approached by any but a perfectly
pure and holy frequentist, is borne away and vanishes from sight."

ATLAS Discovers New Chi_b Resonance

Just as you thought it was over for 2011, and you proceeded to hung the Higgs mass plots on the christmas tree as a wish for stronger signals next year, ATLAS comes out with a new particle discovery. That's what I like of particle physics - there's always so much going on that the excitement is never really over.
High Resolution Images Of Vesta By DAWN

High Resolution Images Of Vesta By DAWN

Dec 23 2011 | comment(s)

NASA is featuring the first high-resolution images of asteroid Vesta as taken by the DAWN spacecraft during a low-altitude orbit. The images show a very interesting surface, battered with old and more recent craters, plus "textures such as small grooves and lineaments that are reminiscent of the structures seen in low-resolution data from the higher-altitude orbits. Also, this fine scale highlights small outcrops of bright and dark material." (from the NASA piece).

Franco Rimondi, 1944-2011

Dec 23 2011 | comment(s)

I was saddened today upon hearing of the death of Franco Rimondi, a colleague in the CDF experiment. Franco was a professor of physics at the university of Bologna since 1980. His research in particle physics encompasses the last forty years, during which he collaborated with many experiments, starting with bubble chamber kaon decay studies in the late sixties, and then ADONE at Frascati in the seventies, and the split field magnet (SFM) at CERN. The experiment he spent most of his research career on was however probably CDF, at the Fermilab Tevatron collider.
Those Deceiving Error Bars

Those Deceiving Error Bars

Dec 22 2011 | comment(s)

Have you ever looked at a histogram with the data displayed as counts per bin in the form of points with error bars, and wondered whether those fluctuations and departures from the underlying hypothesized model (usually overimposed as a continuous line or histogram) were really significant or worth ignoring ?
