I am an experimental particle physicist working with the CMS experiment at CERN. In my spare time I play chess, abuse the piano, and aim my dobson telescope at faint galaxies.... Read More »

I am very happy to report that Professor Giorgio Parisi won another prize. Parisi is an Italian theoretical physicist who is very well known for his decisive contribution to QCD, with the DGLAP equations (the P stands for his last name) that govern the dynamics of gluons. However his work did not stop there - after that result Parisi continued excellent research and it is not by chance that he collected prizes and acknowledgements along the way for the more recent contributions he has given to theoretical physics. 
The 2016 prize called after Lars Onsager is given to Giorgio by the APS
I think it is due time that I point out a few interesting articles that have appeared in the past couple of months in the blog of the AMVA4NewPhysics network, a consortium of 16 among universities, research institutes, and industries that has the goal of studying Higgs physics and new Physics with the LHC, using advanced statistical learning methods.
The issue is not new. Scientific journals require articles to produce quantitative answers - of course, that's how you do science. And scientists usually rely on a formalism based on classical statistics to report those results: they report the probability of their data given some hypothesis. P-values, that is.
On March 3rd and 4th the AMVA4NewPhysics network met in Venice, in the beautiful venue of Ca' Sagredo. Ca' Sagredo is a 500-year-old palace on the Canal Grande, home of the Sagredo family and in the 600s of Giambattista Sagredo, who hosted many times Galileo Galilei there. As for the AMVA4NewPhysics network, it is a "Innovative Training Network" of 16 research institutes, universities and industries that have joined forces to train young scientists in particle physics and the development of advanced multivariate-analysis tools.

How many phenomenological papers discussing the 750 GeV diphoton resonance have you read since December 15th 2015 ? I believe that having read none of them, or ten, does not make a big difference - you missed most of them anyways. In fact, I think the count has gone past 200 by now. 
Do you know what a lucid dream is ? It is the experience of being aware of your asleep state during a dream. Lucid dreaming occurs during the REM phase of sleep, and it is usually created when, while dreaming, one suddenly realizes his or her dreaming state. The dream may then continue, but the individual has some degree of control over what happens. Laws of physics continue to not apply, of course, and one has the power of "writing the script", to some extent. In a sense, one's desires are the driver of the script.
