    "abstract": "The French Academy units of time and length - the second and the meter - are\ntraditionally considered independent from each other. However, it is a matter\nof fact that a meter simple pendulum beats virtually the second in each\noscillation, a `surprising\u0027 coincidence that has no physical reason. We shortly\nreview the steps that led to the choice of the meter as the ten millionth part\nof the quadrant of the meridian, and rise the suspicion that, indeed, the\nlength of the seconds pendulum was in fact the starting point in establishing\nthe actual length of the meter.",
