A set of four brass rulers that add up to one meter. Or, to put it another way, the distance light travels in 299,792,458ths of a second, as specified on the diamond-engraved reverse. This definition establishes a fundamental relationship between the speed of light, time and space – constant physical properties of nature. Precise and universal, this definition does not depend on specific physical prototypes, and enables us to use a common basis for measuring lengths. It follows on from the introduction of the metric system, in which the meter was calculated on the basis of a fraction of the earth’s circumference, which in turn replaced the numerous body units used until then: foot, elbow, toise, palm, fathom… And so, in a unification of language, we moved from measuring bodies to measuring the earth, to arrive at the invariable measurement of time. It’s no longer a material standard, but its physical representation, invariable and reproducible.
