The Plot Thickens: Yet Another Lattice QCD Calculation Restores The Anomaly Of The Muon Magnetic Moment

In a recent post I discussed the conclusions of a study aimed at computing a small but very important correction to the theoretical prediction of the anomalous magnetic moment of the muon. The interest of this lays in the fact that the latter quantity is v ...

Gemstone Classification With A Specific Gravity Scale

The isolation that most of the civilized world has been subjected to, during the past few weeks, has produced a number of nasty effects, first and foremost on our economies, but it has also had a few positive ones. One of them is, at least in my case, an u ...

Nuisance Parameters In Classification Problems: A Simple Example

These days I have been writing a chapter of a book on machine learning for physics, and in so doing I have found myself pondering on how to best explain, in very simple terms, the nocuous effect that model uncertainty may have on the result of a classifica ...

Who Discovered The Top Quark Anyway?

You may be wondering, upon reading the above title of this post, what I am after today: the top quark has been around for 25 years now, and there is no long-standing controversy on who discovered it-almost. Well, I will come to that in due time, but to exp ...
