  • Abstract
    The winds of change are blowing strongly in the International System of Units (known since 1960 as the SI). Already gone is the meter bar, artfully constructed of a platinum-iridium alloy so many years ago, an end-on X-shaped bar carefully scribed by the denizens of the International Bureau of Weights and Measures (BIPM) in Sevres, France.
