"The Flow Of Time" Through Systemic Functional Linguistics [2]

Gribbin (1990: 184-5):

The track of an electron is represented on a Feynman diagram by a line.  An electron that sits in one place and never moves produces a line that moves straight up the page, corresponding to motion in the time direction only; an electron that slowly changes its position, as well as being carried along by the flow of time, is represented by a line at a slight angle to the line straight up the page, and a fast–moving electron makes a bigger angle with the "world line" of a stationary particle.

From the perspective of Systemic Functional Linguistic theory, this demonstrates the error of misconstruing extent in time (duration), as movement in time (location).  In a Feynman diagram, a particle that doesn't move is misconstrued as moving through time, instead of persisting through time.  Particles are not carried along by the flow of time, because this notion confuses the unfolding of processes (flow) with the dimension along which they unfold (time).
