Isochronisms [noun]

By subsequent experiment he verified the law, and the isochronism of the pendulum was discovered.

Thus, in 1720, Julien Leroy occupied himself working out the proper shapes for the inclines to produce this desired isochronism.

In order to produce a note, the succession of shocks must not deviate much from isochronism.

If the isochronism is but little impaired, we obtain a note corresponding to the mean interval of the shocks.

We obtain the notes of both circles, one of which is the octave of the other, if there is no isochronism between the shocks.

Thus was discovered the principle of the pendulum and its "isochronism."

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.

The isochronism of a pendulum vibrating in a cycloidal arc was first discovered by Galileo but he did not apply it to clocks.

The experimental verification of this fact led him to the important discovery of the isochronism of the pendulum.
