Time is the indefinite continued progress of existence and events that occur in apparently irreversible succession from the past through the present to the future. Time is a component quantity of various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material reality or in the conscious experience. Time is often referred to as a fourth dimension, along with three spatial dimensions.
I consider time as flowing or increasing by continual flux & other quantities as increasing continually in time & from ye fluxion of time I give the name of fluxions to the velocitys wth wch all other quantities increase. ...I expose time by any quantity flowing uniformly and represent its fluxion by an unit, & the fluxions of other quantities I represent by any other fit symbols... This Method is derived immediately from Nature her self.

Ein stiller Geist ist Jahre lang geschäftig; Die Zeit nur macht die feine Gährung kräftig. Long is the calm brain active in creation; Time only strengthens the fine fermentation.
