Theory C was discovered by Ivor Catt on 26 May 1976.

"Last night when driving home from work, I realized that an electricity conductor is an energy current insulator, and vice versa. [Heaviside called conductors "obstructors".] I realized that Theory C was not generally different and opposite to Theory N; it was exactly opposite. Since maths is reversible, this means that all of the logic and results and achievements of Theory N carry through into Theory C. However, since it is difficult to be efficient and effective when standing on your head, we can expect great advantages in all fields from moving to Theory C.

At dinner last night I looked at the last few pages of 'Through the Looking Glass' (Lewis Carroll), because obviously I had just walked back out of an electronic looking glass. The Alice book fitted the situation exactly. Startin from 'And then (as Alice afterwards described it) all sorts of things happened in a moment. The candles .... '

Lewis Carroll, being a good mathematician, would of course be fmailiar with the kaleidoscope effect of reversing a theory.

If we return to theory N, there are all sorts of indications that we are on the wrong side of the looking glass. The speed of an electric current signal down a conductor depends on the characteristics (permeability, premittivity), not of the ocnductor, but of the insulator, where the [electric] current is not travelling. This is like saying that the speed at which you drive down the road depends, not on the power of your engine, but on the spacing of the bushes beside the road.

Crazy anomolies like this abound in Theory N, culminating in 'Displacement Current'. Also, a capacitor retains its charge when the conducting plates are removed, &c., &c.

In hias introduction to my book Electromagnetism 1 , 1994, my co-author Dr. David Walton wrote;

" .... I particularly remember his comment that 'all of the stray inductance is not in series with all of the capacitance. In other words, from the point of view of a step pulse, the capacitor was distributed in space and therefore in time. It was as I reflected on this that I 'saw' that a capacitor was in fact a transmission line and the whole universe began to turn itself inside out with the transmission line becoming the fundamental primitive while other concepts such as inductance, capacitance, and mutual inductance were constructed from it. ....
