A Quantum Diaries Survivor

Academics direly need objective, meaningful metrics to judge the impact their publications have on their field of expertise. Nowadays any regular Joe will be able to show many authored papers in their CV, and it will be impossible to objectively assess the relative merits of each and every one of them, if you are trying to rank Joe in a list of candidates for tenure, or just a research job at a University. 

CERN has equipped itself with an inter-experimental working group on Machine Learning since a couple of years. Besides organizing monthly meetings and other activities fostering the dissemination of knowledge and active research on the topic, the group holds a yearly meeting at CERN where along with interesting presentations on advances and summaries, there are tutorials to teach participants the use of the fast-growing arsenal of tools that any machine-learning enthusiast these days should master.

These days the use of machine learning is exploding, as problems which can be solved more effectively with it are ubiquitous, and the construction of deep neural networks or similar advanced tools is at reach of sixth graders.  So it is not surprising to see theoretical physicists joining the fun. If you think that the work of a particle theorist is too abstract to benefit from ML applications, you better think again. 

While spending a few vacation days on a trip around central Italy I made a stop in a place in the Appennini mountains, to visit some incredible caves. The caves of Frasassi were discovered in September 1971 by a few young speleologists, who had been tipped off by locals about the existence, atop a mountain near their village, of a hole in the ground, which emitted a strong draft wind - the unmistakable sign of underground hollows.

I am very glad to observe that Adam Falkowsky has resumed his blogging activities (for how long, that's early to say). He published the other day a blog entry titled "Where were we", in which he offers his view of the present status of things in HEP and the directions he foresees for the field.I was about to leave a comment there, but since I am a very discontinuous blog reader (you either write or read, in this business -no time for both things together) I feared I would then miss any reply or ensuing discussion. Not that I mean to say anything controversial or flippant; on the contrary, I mostly agree with Adam's assessment of the situation. With some distinguos.

I do not keep crocodiles[*] in my drawer, so this short piece will have to do today.... Stephen Hawking, the world-renowned British cosmologist, passed away yesterday, and with him we lost not only a bright thinker and all-round scientist, but also a person who inspired two or three generations of students and researchers, thanks of his will to live and take part in active research in spite of the difficulties he had to face, which he always managed to take with irony. Confined on a wheelchair by ALS, and incapable of even speaking without electronic assistance, he always displayed uncommon sharpness and wit.

Large amounts of ink (well, electrons) have been spilt over the web in the past few months to discuss the #MeToo movement. It seems this blog will eventually join the crowd, although a bit belatedly, and with a slightly different viewing angle. After keeping silent on the matter, I am stimulated to discuss it after a BuzzFeed article exposed several cases of alleged sexual harassment and related inappropriate behavior by world-class cosmologist-cum-science-pop-guy-cum-skeptic Lawrence Krauss. Plus, yesterday was international women's day, and I never miss a chance to miss a deadline.

Statistical hypothesis testing is quite boring if you apply it to cases where you know the answer, or where the data speak loud and clear about one hypothesis being true or false. Life at the interface between testability and untestability is much more fun.

This is just a short note - a record-keeping, if you like - to report that my long review on "Collider Searches for Diboson Resonances" has now appeared on the online Elsevier site of the journal "Progress of Particle and Nuclear Physics". I had previously pointed to the preprint version of the same article on this blog, with the aim of getting feedback from experts in the field, and I am happy that this has indeed happened: I was able to integrate some corrections from Robert Shrock, a theorist at SUNY, as well as some integrations to the references list by a couple of other colleagues.

Dark Matter (DM), the mysterious substance that vastly dominates the total mass of our universe, is certainly one of the most surprising and tough puzzles of contemporary science. We do not know what DM is, but on the other hand we have a large body of evidence that there must be "something" in the universe that causes a host of effects we observe and which would have no decent explanation otherwise. 

Great news for the CMS experiment - and for Italy, and for my institution, Padova, where I coordinate accelerator-based physics research for INFN. Professor Roberto Carlin, a longtime member of the CMS experiment, where he has taken many important roles in the construction and operations of the experiment, and recently was deputy spokesperson, has now been elected spokesperson. This consolidates a "rule" which sees Italian physicists at the lead of the experiment every other term, after Tonelli (2010-12) and Camporesi (2014-16).
