Example Sentences
- "Time was vulnerable to the force of gravity. So Breguet came up with the tourbillon, which isolated the balance wheel and escarpment off on a little platform of their own, geared to the third wheel, rotating about once a minute, assuming in the course of the day most positions in 3-D space relative to the gravity of the Earth, so the errors would cancel out and make time impervious to gravity."
