“History, human or geological, represents our hypothesis, couched in terms of past events, devised to explain our present-day observations.” HumansPastScienceTermHistoryEventsObservationHypothesisPresent DayPast Events Author:M. King Hubbert
“Historical chronology, human or geological, depends... upon comparable impersonal principles. If one scribes with a stylus on a plate of wet clay two marks, the second crossing the first, another person on examining these marks can tell unambiguously which was made first and which second, because the latter event irreversibly disturbs its predecessor. In virtue of the fact that most of the rocks of the earth contain imprints of a succession of such irreversible events, an unambiguous working out of the chronological sequence of these events becomes possible.” IfsFirstsHumansPersonsMadeTwoFactsEarthSciencePrinciplesHistoryVirtueRocksEventsDependsMarkHistoricalWork OutLatterWetPlatesClaySequenceSuccessionCrossingsExaminingPredecessorsIrreversibleChronologyScribes Author:M.
