Since the Green's function, as a function of one of its variables, is a potential due

to a unit point charge, this symmetry merely represents the

interchangeability of the source and the observation points. From form (1.40) for

G(x, x') it is ...

coordinates in space and time are related by the Galilean transformation, x = x +

vt, t'=t.
