That's for massless particles in a vacuum (~.98'/s). Electrons in copper
wire are much slower. Years ago in Byte there was an article about DRAM
where they through out a figure like .25" per nanosecond at 5V in copper
traces (they used the reciprocal of 4 seconds per inch--I think). But I've
wondered about this ever since. Does anyone have accurate figures on this?
