[Elecraft] Maxwell's Equations.

[Tom Azlin N4ZPT]

Sorry you are not enjoying the thread James.

Seems like many of the email on this reflector has nothing to do with 
the K3. I'm an average user of the K3 (and an in progress K2 builder). 
Talking about the actual equations and the history of their development 
seems to me to be of general interest to many of the readers of this 
list given the other responses.
