Consider a particle P that is described by the chain of events

\mbox{\fontsize{14}{18}\selectfont $ \Psi ^{\sf{P}} = \left( \sf{P}_{0} , \sf{P}_{1} \ldots \sf{P}_{\it{k}} \ldots \right) $}

where the phase of events is given by

\mbox{\fontsize{14}{18}\selectfont $ \epsilon_{\it{k}} = (-1)^{\it{k}} = \pm1 $}

so that ϵ alternates back and forth between +1 and -1 for consecutive events along the chain. Definition: if a chain of events like this is also in historical order, then we say it is in chronological order.

Sensory interpretation: if the Earth is used as a frame of reference, then Ψ is a chain of events that alternates between day-time and and night-time incidents in the same order as the calendar date.
