Thus was discovered the principle of the pendulum and its "isochronism."
Effects produced when the isochronism of the shocks is not perfect.
By subsequent experiment he verified the law, and the isochronism of the pendulum was discovered.
The angular velocity is regulated by a Watt's governor, which secures an isochronism of the motion independently of the charge.
A departure from the law of isochronism may then be expected to develop itself.
The experimental verification of this fact led him to the important discovery of the isochronism of the pendulum.
An inspection of them will show how little remained to be done when the isochronism of the pendulum was discovered.
Adjusted to isochronism indicates that the watch functions uniformly during the entire twenty-four hours running.
Three adjustments are usually made, viz.: for isochronism, temperature and position.
The principle of the isochronism of a balance spring was discovered by Hooke, and first applied to a watch by Tompion.
