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…

The Z machine at Sandia National Laboratories is moving us toward a fusion future by stepping into the past - in this case using a 19th century device called a Helmholz coil, which is a pair of…

Today the Baryon Oscillation Spectroscopic Survey (BOSS) Collaboration announced that they have measured the scale of the universe to an accuracy of one percent.    BOSS is the largest…

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…

Have you ever seen a demonstration of any of the principles of General Relativity?  What about The "famous" "rubber sheet" analogy, where a heavy ball, like a bowling ball, is placed on a rubber…

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…
