On A Roll

1 week ago | science20.com | Tommaso Dorigo

What? Another boring chess game? Buzz off, this is my blog, and if I feel like posting a chess game, that's what is going to happen. But if you like the game, stay here - this is a nice game. Again played after hiours today, and again on a 5' online blitz server (chess.com). What amazes me is that these days I seem to have a sort of touch for nice attacks and brilliant combinations. Let me show you why I am saying this.
When The Attack Plays Itself

1 week ago | science20.com | Tommaso Dorigo

After a very intense day at work, I sought some relaxation in online blitz chess today. And the game gave me the kick I was hoping I'd get. After a quick Alapin Sicilian opening, we reached the following position (diagram 1):As you can see, black is threatening a checkmate with Qxg2++. However, the last move was a serious error, as it neglected the intrinsic power of my open files and diagonals against the black king. Can you find the sequence with which I quickly destroyed my opponent's position? 1.
Toponium Found By CMS!

2 weeks ago | science20.com | Tommaso Dorigo

The highest-mass subnuclear particle ever observed used to the the top quark. Measured for the first time by the CDF experiment in 1994, and subsequently confirmed by CDF and D0 in 1995, the top quark is the heaviest elementary particle we know of, and it is a wonderful physical system per se, which has been studied with momentum in the past thirty years at the Tevatron and at the LHC colliders.
The Problem With Peer Review

3 weeks ago | science20.com | Tommaso Dorigo

In a world where misinformation, voluntary or accidental, reigns supreme; in a world where lies become truth if they are broadcast for long enough; in a world where we have unlimited access to superintelligent machines, but we prefer to remain ignorant; in this world we are unfortunately living today, that is, the approach taken by scientists to accumulate knowledge - peer review - is something we should hold dear and preserve with care. And yet... Yet the peer review system is crumbling.
Interna

In the past few years my activities on this site - but I would say more in general, as the same pattern happened also on social media - have progressively shifted away from pure casual blogging and reporting of personal matters to a more focused discussion of scientific topics, always lingering around my research interests. I believe this rather unintentional but unavoidable drift has two main causes.
The Probability Density Function: A Known Unknown

1 month ago | science20.com | Tommaso Dorigo

Perhaps the most important thing to get right from the start, in most statistical problems, is to understand what is the probability distribution function (PDF) of your data. If you know it exactly -something that is theoretically possible but only rarely achieved in practice- you are in statistical heaven: you can use the maximum likelihood method for parameter estimation, and you can get to understand a lot about the whole problem.
Summer Lectures In AI

1 month ago | science20.com | Tommaso Dorigo

Winter is not over yet, but I am already busy fixing the details of some conferences, schools, and lectures I will give around Europe this summer. Here I wish to summarize them, in the hope of arising the interest of some of you in the relevant events I will attend to. From June 8 to June 12 we are organizing with the MODE Collaboration its fifth workshop, "V MODE Workshop on Differentiable Programming for Experiment Design".
Unsupervised Tracking

2 months ago | science20.com | Tommaso Dorigo

Pattern recognition is an altisonant name to a rather common, if complex, activity we perform countless times in our daily lives. Our brain is capable of interpreting successions of sounds, written symbols, or images almost infallibly - so much so that people like me, who have sometimes trouble to recognize a face that should be familiar, get their own disfunctionality term - in this case, prosopagnosia. Pattern recognition is also an all-important task in machine learning.
Hey AI, Design A Calorimeter For Me

2 months ago | science20.com | Tommaso Dorigo

As artificial intelligence tools continue to evolve and improve their performance on more and more general tasks, scientists struggle to make the best use of them. The problem is not incompetence - in fact, at least in my field of study (high-energy physics) most of us have grown rather well educated on the use and development of tailored machine learning algorithms. The problem is rather that our problems are enormously complex.
The Multi-Muon Analysis - A Recollection

2 months ago | science20.com | Tommaso Dorigo

As part of the celebrations for 20 years of blogging, I am re-posting articles that in some way were notable for the history of the blog. This time I want to (re)-submit to you four pieces I wrote to explain the unexplainable: the very complicated analysis performed by a group of physicists within the CDF experiment, which led them to claim that there was a subtle new physics process hidden in the data collected in Run 2.

hereby propose that the dark photon of some Standard Model extensions be from now called the SKOTON, preserving symmetry with the photon (so that both names come from Greek for, respectively, light and darkness), and avoiding the oxymoron (dark photon). https://t.co/pWPffS3pLQ
