(There is a related group in the amateur radio crowd as well. These
people are so good at it they hardly need radios at all -- they can
directly integrate Maxwell's equations in their heads in real time.

div E = 4 pi rho
div B = 0
curl E = -1/c x dB/dt
curl B = 1/c x dE/dt + 4 pi/c J

rho=charge density
J=current density

Curiously, these people even refer to those who are not as capable (or
perhaps choose not to be as capable) as "appliance operators".

As a matter of fact, I have an amateur radio license.
That's where I got the phrase from.
Bwahahahahahaha.
