Foucault’s pendulum would never stop. It would keep swinging, she understood, after she and her father left the Panthéon, after she had fallen asleep that night. After she had forgotten about it, and lived her entire life, and died. Now it is as if she can hear the pendulum in the air in front of her: that huge golden bob, as wide across as a barrel, swinging on and on, never stopping. Grooving and regrooving its inhuman truth into the floor.
