```I'm not sure that's relevant:  the *degree* to which the top-side of the
frying pan heats up is related to the heat capacity (if I recall the term
correctly - or perhaps it's specific heat?) of the frying pan - i.e., the
more heat it can absorb per unit volume for a given temperature rise, the
slower the temperature of a portion far from the heat source will rise.  But
that doesn't prohibit instantaneous propagation (which would mean that the
far portion's temperature rise would *begin* immediately, regardless of how
slow it was).
