From the fabric of space-time to the limits of the quantum world, Neil Johnson takes us on a journey through time in his 1999 Christmas Lecture series “Arrows of Time”.

The third lecture of the series, where this clip is from, deals with how oscillations of sound or light can define a unit of time.

  1. "marching through" doesn't really sound very much like a "wave". Because with a wave,

    it doesn't actually travel through, rather it simply passes its energy from one spot to the

    next. And I'm sure you know this already. So how can you say that the electrons are

    marching through the material? Are you trying to say that electricity is not a wave?
