Rhythmites definition
Rhythm (from Greek ῥυθμός, rhythmos, "any regular recurring motion, symmetry" ) generally means a "movement marked by the regulated succession of strong and weak elements, or of opposite or different conditions". This general meaning of regular recurrence or pattern in time can apply to a wide variety of cyclical natural phenomena having a periodicity or frequency of anything from microseconds to several seconds (as with the riff in a rock music song); to several minutes or ho… WebbTime Scales. A definition for the term "time scale": 16th General Assembly of the International Astronomical Union Grenoble, France (1976) Resolution No. 4 by Commissions 4 (Ephemerides) and 31 (Time) 3.(a) a useful time scale is generated by any process which enables dates to be assigned to events
