Big Data & AI : the symphony of datas and measures
Who has never been moved by a song or other piece of music, an orchestral masterpiece, perhaps, or a tuneful number sung on the radio? What is the magic that causes that thrill that a melody can give us?
In order for music to make the body resonate in that special way, every note must be in its place, produced with accuracy and precision by the instrument, whether string, brass, percussion, or voice… It’s only when all the ‘ingredients’ are there in the right measure that anyone can say “This music is good”
At first sight, the two images above don’t have anything in common.

A Smart approach to calibration – Why we should forget calendar-based calibrations
If the current practice of calendar-based calibration has eventually convinced us that it is a good thing, a brief look at its historical context leads us to a consideration that sheds a totally different light on this issue. First, we will clarify that legal metrology set this practice in place to grant fairness in commercial transactions for both customers and suppliers.

Covariance Evaluation by Means of Uncertainty Assessment
One of the key points in modern measurement science is the evaluation of measurement uncertainty, according to the definition given by the International Vocabulary of Metrology (VIM) [1] and the procedure recommended by the Guide to the Expression of Uncertainty in Measurement (GUM) and its supplements [2]–[4]. According to these documents, when several sources of uncertainty are present, the related standard uncertainties shall be quadratically combined, and the covariances must be considered, if present [2].

G.U.M.: There may be a pitfall
Cet article est également disponible en français.
The uncertainty calculation, even if not widely accepted by all industrialists, occupies more and more metrologists around the world. In order to help them out, the J.C.G.M. WG 1 published in 1995 the J.C.G.M. 100 document, better known as G.U.M. (Guide to the expression of Uncertainty in Measurement). This document is quoted for a long time in ISO standards.
