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.

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.
This evening I am blogging from a residence in Sesto val Pusteria, a beautiful mountain village in the Italian Alps. I came here for a few days of rest after a crazy work schedule in the past few days -the reason why my blogging has been intermittent. Sesto is surrounded by glorious mountains, and hiking around here is marvelous. But right now, as I sip a non-alcoholic beer (pretty good), chilling off after a day out, my thoughts are focused 500,000,000 kilometers away.
