ISOCHRONOUS

(Yunanca köken — orijinale bakınız.) Two pcnduliuns which vibrate in the same time are isochronal; or the vibrations of a pendulum In the curve of a cycloid are so, being all performed in the same time, whether they are to be large or small. Isochronal lines are those along which a heavy body descends with a uniform velocity. [s. 632]
