May 20th is the 4th annual World Metrology Day sponsored by the Bureau international des poids et mesures (BIPM)(International Bureau of Weights and Measures) and the Organisation Internationale de Métrologie Légale (OIML)(International Organization of Legal Metrology).
Metrology is the science of measurement so it’s used everywhere, from cutting edge laboratories to most everyone’s home. I’d be hard pressed to think of any scientific endeavor that didn’t involve metrology at some level. From a simple scale (ruler) to measure the length of a leaf by a botanist to the atomic clocks that make astronomical observations so precise, metrology is everywhere.
On a personal level, metrology is my favorite branch of science I’m a metrology geek. I love to create new measuring instruments and techniques and of course just simply measure. I’m in awe of the cutting edge research done by fine organizations around the world such as the NIST in the USA.
