Physics

Scientific consensus is not gospel dogma to be enforced, instead it should, and MUST change in the face of contrary data.  There are theories like evolution, general relativity, and climate change which are truly settled science.  Inflation (and string theory) are not there yet.  Letters signed by 33 or 33,333 prestigious physicist won't make that so.  Only data can.  

Yesterday I visited the Liceo “Benedetti” of Venice, where 40 students are preparing their artwork for a project of communicating science with art that will culminate in an exhibit at the Palazzo del Casinò of the Lido of Venice, during the week of the EPS conference in July.

The field of Big History attempts to tie events from cosmology, life evolution, and history into narratives and common themes.

Flavor-Geometric Duality and Pseudo-Euclidean Symmetry of Neutrino Mixing in Semi-Empirical Phenomenology

 

I. Suggested early by the author, main equation of neutrino mixing semi-empirical phenomenology is given by

A little while ago I encountered an interesting problem, which I had fun solving by myself. I think my solution is not original (it must have occurred to others a gazillion times in the past) but I do believe the implementation is nice, so I want to share it with you here.
The general problem

Imagine you are given a set of counts distributed in bins of a histogram. This could be, for instance, the age distribution of a set of people. You are asked to assign uncertainty bars to the counts: in other words, estimate a "one-sigma" interval for the relative rate of counts in each bin.
Innovative training networks are a European Community concept funded by the Research Executive Agency, under the project called "Marie Curie Actions". The idea is that the EU helps build structures that provide interdisciplinary training to skilled graduate students, providing them with knowledge and skills that make them attractive for the work market and useful to society, while boosting the research projects that the EU is interested in.
GSI, the Helmholtz Centre for Heavy Ion Research, is a laboratory located near the town of Darmstadt, in central Germany, just a few miles away from the Frankfurt airport. The centre was founded in 1969, and has since then been a very active facility where heavy elements are studied (six rare heavy ones were in fact discovered there, including the one they named Darmstadtium!), and where a wide research plan of nuclear physics is carried out.

With a slightly anti-climatic timing if we consider the just ended orgy of new results presented at winter conferences in particle physics (which I touched on here), the LHCb collaboration outed today the results of a measurement of unity, drawing attention on the fact that unity was found to be not equal to 1.0.

On Neutrino CP-Violation Idea

Primarysuggestive qualitative ideas are especially important in basic frontierphysics. As examples, Einstein’s thought experiment on space-time connection inspecial relativity, equivalence principle in General relativity and others.

Snow is melting in the Alps, and particle physicists, who have flocked to La Thuile for exciting ski conferences in the past weeks, are now back to their usual occupations. The pressure of the deadline is over: results have been finalized and approved, preliminary conference notes have been submitted, talks have been given. The period starting now, the one immediately following presentation of new results, when the next deadline (summer conferences!) is still far away, is more productive in terms of real thought and new ideas. Hopefully we'll come up with some new way to probe the standard model or to squeeze more information from those proton-proton collisions, lest we start to look like accountants!
