Okay, the year is not over just yet, but it is already time for a little accounting of the traffic on this site in the course of the last eight-and-a-half months -that is, since I moved my blog to…

The turnaround of the three physics questions I offered a few days ago, to stimulate your neurons and extract you from the chocolate and alcohol flood caused by the usual string of Christmas parties…

Two days ago I offered you three problems in experimental particle physics, of varied complexity. Three readers tried answering the test in the comments thread: a rather underwhelming turnaround, but…

Scared by the void of Christmas vacations ? Unable to put just a few more feet between your mouth and the candy tray ? Suffocating in the trivialities of the chit-chat with relatives ? I have a…

Two days ago, there was a post on backreaction about the naturalness in science, which is considered by many as a fundamental concept. The point of view expressed in the post is quite easy to grasp…

This morning LHC machinists, experimentalists from the LHC experiments, as well as other CERN personnel gathered in the Main Auditorium at CERN to give their end-of-year report. After a LHC status…
