In the age of big data, it is time to ensure that units are routinely documented for easy, unambiguous exchange of information. Robert Hanisch is the director of the Office of Data and Informatics at ...
If scientists had sacred objects, this would be one of them: a single, closely guarded 137-year-old cylinder of metal, housed in a vault outside of Paris. It is a prototype that precisely defines a ...
Many measurement systems were developed as civilisation evolved. The imperial system is nothing if not quirky. Readers may recall that a rod, pole or perch equals 5½ yards or 16½ feet, with 40 rods to ...
