Hi Jim,

In the 18th century politics, someone who straddled the fence was
called a Mugwump - their mug on one side and their wump on the other.

The reason I asked is because the
only thing I can find is something called a phase conjugate mirror,

It was suitable enough, but rather slim.

which has some really interesting behavior. And not exactly the
behavior being discussed in this thread. Time reversal for example.

This issue of what "is" and "is not" behavior being discussed is
strictly a matter of interpretation. Insofar as discussion continues,
it is quite evidently what "is" being discussed (a tautology). After
all, how many could mistake a director from a reflector and after
discussion still emerge confused?
