I am in the [sic] for & conference.

Metrology is the science of measuring. Most (rich) countries have a metrological agency, which is responsible for maintaining measurement standards, they know how heavy 1 kg is and how long 1 meter. (Important for trade and science.)

It is a fun meeting, close to 100% about uncertainties. An enormous contrast to science in the media where uncertainties are mostly ignored and everyday science which is half uncertainties.


The meeting reminded me of my personal favorite XKCD. xkcd.com/1985/
