Foucault’s Pendulum

Vendredi, mars 6th, 2009

Within the Pantheon hangs Foucault’s Pendulum. This giant marble swings almost endlessly while the earth rotates around its axis. Even if by 1851, it was already known that the earth rotated, it was this experiment by Foucault that proved it physically. While the relaunch of the marble should made very carefully to validate the experiment, this Pantheon worker  reset it manually like if he was the proud Guardian of an ancient craftwork.
