[Elecraft] Negative Resistance????

[Lee Buller]

What am I missing here?  Negative resistance?  What are we talking about here?  I always thought that you either had resistance or there was no resistance.  You cannot have no resistance because you will always have some...at least in the physics in my head.  To me, negative resistance is one the other side of the Y coordinate and could only happen in mathmatics and not in real life.  Conductance?  No, I do not thing that is what we are talking about either.  HMMMMM.  Negative resistance doesn't make sense to me although I guess if they are using those special ceramic compounds cooled down to -254 degree or something.  Even then, I just can't get idea of negative resistance.  Negative resistance strikes me a bit funny.
