I received yesterday a copy of the brand-new book by Ilya Narsky and Frank Porter, "Statistical Analysis Techniques in Particle Physics" (Wiley-vch 2014), and I would like to offer here my…

Chapter 10 of the report on the 2013 community summer study held at Snowmass, titled "Communication, Education, and Outreach" is available since Jan 24th in the Cornell ArXiv. It is a 26-pages…

In a paper posted to the arXiv a few days ago Stephen W. Hawking the preeminent expert on black holes argued quite effectively that given what we know about quantum gravity they don't exist. Quantum…

"The most important task at hand is experimental. Based on our considerations of dynamical symmetry breaking through preons and the assumption of universal size for all quarks and leptons, we are led…

I must say I feel proud of myself tonight. In Italy a unified procedure to rank candidates to the position of associate or full professor has been launched last year, and I of course participated to…

Measuring a 27-dimensional quantum state is a time-consuming, multistage process using a technique called quantum tomography, which is similar to creating a 3D image from many 2D ones. Researchers…

"Statistical power does not corrupt" Leland Wilkinson, "Statistical Methods in Psychology Journals", in American Psychologist, August 1999. [Note: "power" in the context of statistical tests measures…

Tetraquarks are hypothetical particles made up by four quarks (two quarks and two antiquarks). Unlike mesons (quark-antiquark pairs) and baryons (three-quark or three-antiquark systems), the quarks…

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…

I will try to keep my Newtonian wig on. Digressions will be in well-defined sidebars. Time to serve the meat and potatoes. The Action for the Newtonian Gravitational Field Two things go into this…
