Physics

Besides being a giant triumph of theoretical physics and the definitive seal on the correctness of the Standard Model -at least at the energies at which we are capable of investigating particle…

Neutrinos are among the more mysterious elementary particles in the universe: Billions of them pass through every cell of our bodies every second, yet these ghostly particles are incredibly difficult…

"The era of the atom" is a new book by Piero Martin and Alessandra Viola - for now the book is only printed in Italian (by Il Mulino), but I hope it will soon be translated in English. Piero Martin…

I used to post on this blog very abstruse graphs from time to time, asking readers to guess what they represented. I don't know why I stopped it - it is fun. So here is a very colourful graph for you…

On April 11th 2015 I delivered a presentation on the subject of Quantum Gravity in which I questioned the basic assumption that quantum is more fundamental than relativity.  Relativization is…

A very popular urban myth is that window glass is a liquid.  This apparently originated by the recognition that old European cathedrals had windows with the glass being thicker at the bottom…

Temperature allows us to make a simple statistical statement about the energy of particles without having to know the specific details of the system. How do quantum particles reach a state…

Particle physics is so cool - you get to build huge detectors with a specific goal clearly stated in your letter of intents and technical proposals, but are then allowed to use them to study many…

John Baez writes in "The Crackpot Index - A simple method for rating potentially revolutionary contributions to physics": 15.   10 points for each statement along the lines of "I'm…

The most probable date for Good Friday is April 3, 33 AD. This date is due to Isaac Newton.Easter is that holiday that wanders around in the calendar and which you never quite know when will take…
