"1. Interaction with matter changes the neutrino mixing and effective mass splitting in a way that depends on the mass hierarchy. Consequently, results of oscillations and flavor conversion are…

  Modern physics is not accidentally relativistic and quantum, or in other words, Einstein-relative as well as Everett-relative (Bell-violating Everett-relativity is the very core of quantum…

Less than three weeks separate us from the XVI Neutrino Telescopes, a very interesting conference held in Venice every two years. The physics of neutrinos is a very special niche in the realm of…

On Friday I traveled to Belluno, a town just south of the north-eastern Italian alps, to give a lecture on particle physics to high-school students for the "International Masterclasses". This was the…

Suppose we we tell you everything quantum mechanics can tell you about a quantum particle; what do you really know? Unfortunately, you still cannot predict with certainty the outcome of a simple…

A preprint article by the IceCube collaboration captured my attention today in the Cornell Arxiv, and even more interesting was the main result of the analysis it reports, which can be shown as a "…

How much do you accept science, cat? Robert Couse-Baker, CC BY-SA By Eric Cavalcanti, University of Sydney It’s a century-old debate: what is the meaning of the wave function, the central object of…

I have decided to rescind this proposal.  The swap of time t for space R and visa versa really didn't change anything: a scalar operator was still needed and the single value of time needed…

Don't like the second law of thermodynamics - that heat transfer has limits when trying to do work? Maybe you can just use a different one. Rather than being an immutable fundamental law,…
