One of the most suprising results of the "Machine Learning for Jets" (but really, for particle physics in general) workshop I attended in New York City two weeks ago was the outcome of a challenge that the organizers had proposed to the participants: find a hidden signal of some new physics process in a dataset otherwise made up of some physics background, when no information on the new physics was given, nor on the model of the background.<\p>

The third "Machine Learning for Jets" workshop is ongoing these days at the Kimmel centre of New York University, a nice venue overlooking Washington Square park in downtown Manhattan. I came to attend it and remain up-to-date with the most advanced new algorithms that are been used for research in collider physics, as I have done last year. The workshop is really well organized and all talks are quite interesting, so this is definitely a good time investment for me.

What hurts you is not what you don't know, but those mistaken assumptions which "everyone knows to be true".

Although you probably did not notice, this blog has been inactive during the past three weeks. The reason is simple: I took a break, treating myself to a 24-day trip to Thailand and the Philippines. Anticipating that many of the places I would visit would offer non-existent or very bad internet connection, I decided that it was going to be frustrating to pretend I could blog during the trip, and just left my laptop at home (or rather, in the Bangkok hotel which I first visited for a conference, before leaving for the tour).
I am currently in Bangkok, where the final 2019 meeting of the CMS collaboration started today. The meeting was inaugurated this morning with an official visit of Her Royal Highness Princess Maha Chakri Sirindhorn, giving me the rare opportunity to miss an appointment with a princess, something that was still missing from my repertoire. Checked now. 
Last month the Museum of Natural History of Venice hosted, in the last room of the exhibit called "room of the cetaceans" (where a large skeleton of a whale hangs from the ceiling), an exhibit of artwork produced by high-school students from the Venice area. The event, which belongs to the "Art and Science across Italy" project, was the culminating point of a series of lectures on particle physics, on science in art, and related topics which involved the students and INFN personnel from the Padova section.
