  • n. The state of being isochronous.


From Ancient Greek  (iso, "equal") +  (chronos, "time") + -y (Wiktionary)


  • Percussive force is directly related to height and the motion of the pendulum seems to involve essentially equilibrium with respect to the height of the bob (and time also, but isochrony did not lead directly to a recognition of time's importance.)

    Galileo Galilei

  • Moreover, isochrony ” equal times for equal lengths of string, despite different weights ” goes someway towards showing that time is a possible form for describing the equilibrium (or ratio) that needs to be made explicit in representing motion.
