“Learning to walk in high heels will keep you on your toes.”
Metric systemIn 1790, acting on a motion by a bishop, Charles Maurice de Talleyrand (1754-1838), the French National Assembly decided to create a simple, stable, decimal system of measurement units. The earliest metre unit chosen was the length of a pendulum with a half-period of a second. On 30 Mar 1791, after a proposal by the Académie des sciences (Borda, Lagrange, Laplace, Monge and Condorcet), the Assembly revised the definition of the metre to be 1/10 000 000 of the distance between the north pole and the equator. On 7 Apr 1795, the Convention decreed that the new “Republican Measures”were to be henceforth legal measures in France. The metric system adopted prefixes: greek for multiples and latin for decimal fractions.« |
