A Few Lectures You May Want To Attend To

In the next few days I have a busy schedule with a few lectures gravitating around the use of deep learning technologies for fundamental physics research. This is of course no news, but I thought that my blog is the proper place to list a few pointers, in ...

Searching In The Dark: Unsupervised Learning Meets Fundamental Science

The title of this post is the same of a non-technical presentation I gave today at the 2021 USERN Congress. The USERN (Universal Scientific and Education Research Network) is an organization fostering the diffusion of science, which provides prizes to rese ...

Gravitational Waves In 3D, Thoughts On Visualization Of A Fundamentally Different Astronomical Messenger.

O ne of the strongest results that Astronomy can produce is an image, a picture of a distant natural event we would never otherwise know about. Gravitational wave astronomy, however, focuses on just detecting gravitational waves. Each detector, which must ...

One More Episode In The Dark Matter Search Saga

Do you remember the DAMA-LIBRA experiment? It is a underground detector made of sodium iodide crystals buried under the rock of the Gran Sasso mountain in central Italy, which took data for over a decade in the search of the elusive signal that slowly-movi ...

Correlation, Causation, Independence

This is a post about basics. That's because I think a point needs to be made which is surprisingly not as well-known as its elementary nature would have you guess. Correlation-in its most used version, due to Pearson- is a measure of how two quantitie ...

Photons And Neutral Pions

A bit over a half into my course of particle physics for Masters students in Statistical Sciences I usually find myself describing the CMS detector in some detail, and that is what happened last week.   The course My course has a duration of 64 hours, and ...

Radiation Zero

Interference is a fascinating effect, and one which can be observed in a wide variety of physical systems- any system that involves the propagation of waves from different sources. We can observe interference between waves in the sea or in a lake, or even ...

Veritasium Is Wrong. The Energy Probably Flows Through The Wires. Quantum Field Theory Says So.

A  couple of weeks ago Derrick Muller of the YouTube Channel Veritasium made a video asserting that the electrical energy in a circuit does not flow through the wires but through the fields. This is true and yet also a misleading misconception. This misco ...

The Search for a Theory of Everything

A theory of everything has been the Holy Grail of some of the greatest physicists of the last century, from Albert Einstein to Stephen Hawking. A theory of everything, a single, all-encompassing theoretical framework which would be able to explain, cohere ...

Tetra-Neutronium!

The neutron, discovered in 1932 by Chadwick, is a fascinating particle whose existence allows for the stability of heavy nuclei and a wealth of atoms of different properties. Without neutrons, Hydrogen would be the only stable element: protons cannot be br ...
