I once was an active chessplayer, but work duties have long taken tournaments off my plate - I simply do not have the time to sit through long hours of chess battles. So I play blitz online on chess.com (my handle is "tommasodorigo", in case you wondered).
Humanity progresses thanks to the diffusion and sharing of human knowledge. In particular, scientific progress is brought forth by the sharing of ideas, measurements and experimental results among scientists, and the distribution of excellent education. We have grown very good at doing that, but can we improve the sharing of knowledge for the common good? The answer is certainly yes, as the interconnection of the scientific community and the interdisciplinarity of its efforts are hampered by borders, language barriers, cultural differences, political influences, religious hindrances, education system challenges, and also by different conventions, policies, metrics in the different areas of scientific research.
At about this time of the year I find myself teaching my students about the construction of V-A theory, which is a milestone in the construction of the Standard Model of particle physics. And in so doing I rejoice about having a chance to tell them the details of one of the most brilliant experiments of the twentieth century, one performed in 1957 by Maurice Goldhaber with his colleagues Grodzins and Sunjar, and which has become a cornerstone of the physics of weak interactions and of particle physics in general.
The DeepLearn school series, now reaching the seventh edition, offers insight into artificial intelligence and applications in a week-long course, tightly packing a significant number of high-profile instructors. The present edition, currently being held at the Technical University of Lulea, in the north of Sweden, features the following:- Sean Benson, Netherlands Cancer Institute- Thomas Breuel, Nvidia- Hao Chen, Hong Kong University of Science and Technology- Janlin Chen, University of Missouri- Nadya Chernyavskaya, CERN- Efstratios Gavves, University of Amsterdam- Quanquan Gu, University of California Los Angeles
For some reasons, my personal web page features high in web searches for master thesis offers. I got to learn this by inquiring with a few students who asked me to supervise them remotely on some of the offered topics: where did they get to know about my research activities, and what led them to pick my offers? They all answered that they bumped into my web page section "thesis offers". Well, at least that was no wasted time when I wrote it.
In a recent post in this blog I discussed the idea of exploiting the properties of negative muons for a new kind of imaging technique of unknown volumes of material. The idea is based on the fact that negative muons stopped inside matter have a lifetime that is modified by nuclear interactions, so that a precise detection of their lifetime and point of decay becomes a means of inferring the composition of unknown volumes. Here, I want to offer the results of a quick simulation of the processes, to show that the idea is not so far-fetched.Different techniques for muon tomography
Are you a recently (8 years) appointed Ph.D. graduate in fundamental physics, who wants to work in Italy? This post is for you. The INFN is opening 20 positions for foreigners who would like to join a group of research in one of the INFN sections (there are 25 across Italy). The positions are for one year, renewable, and the salary is competitive, given that it is roughly at the level of a starting associate professor in Italy. Note, also Ph.D. students who plan to graduate before November 1st 2023 can apply! Also, the 8-years limit can be waived if you spent time in maternity, military service, or illness. The winning candidates are expected to start their contract before November 2023.
In the final day of the ICNFP 2022 conference in Kolympari (Greece), we could listen to an enlightening presentation by Prof. Marek Karliner (Tel Aviv University), who is an absolute authority on the matter of the theory of hadron spectroscopy.
A reader of this blog left an interesting question in the comments thread of the article I wrote on recent ATLAS results two days ago. As I tried to answer the question exhaustively, I think the material might be of interest of other readers here, so I decided to make an independent post of it, adding some more detail.John asks whether it is possible that what we see, when we plot the mass of a particle, is the true distribution of values of the particle - i.e. that the particle does not have only one mass, but a distribution of values. The question is not an idle one! So let us discuss it below. I will make a few points to clarify matters.1. We estimate by proxy
Bill Murray gave a nice summary of recent results from the ATLAS collaboration at the ICNFP conference this morning, and I will nit-pick a few graphs from his presentation to show the level of detail of investigations in subnuclear processes that the Large Hadron Collider (LHC) is providing these days, as seen from the lens of one of its two main microscopes, the wondrous ATLAS detector.The LHC is taking data. What, again?
I arrived to Kolymbari, a nice seaside resort on the western coast of the Greek island of Crete, late yesterday night, and am now already immersed in the morning session of the XI edition of the International Conference on New Frontiers in Physics. This event, which takes place at the Orthodox Academy of Crete in Kolymbari since 2012, takes a rather broad view on advances in both experimental results and theory of fundamental physics.
In over 15 years of blogging, in this and previous sites, I have mostly stayed away from the topic of climate change, the environmental catastrophe we are creating with our "perennial growth" myths and our disdain of our planet and the other species that inhabit it, and the continuous slaughter of over a billion animals every year for our unnecessarily opulent lunch tables.
Today I am back from one of the most interesting workshops I ever attended to, and I wish to share some thoughts I had on possible ways to enhance our research of new ideas for future particle detectors with you. Those ideas come from discussions with other participants to the workshop, or just from re-digesting things I have been pondering over for a while.
