[Elecraft] Negative Resistance????

How does negative frequency strike you?

An oscillator can be conveniently modeled with the concept of negative
resistance . . .

> 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.
