Place and Time.)

======================================

Just an addition -

You can't deal with Reflections without involving Distance, Velocity,
ECHO's, Place, and, above all, TIME.

Attempted steady-state analyses reduce to non-sense without involving TIME.

But it is a simple matter to relate power levels, one to another, dB-wise or
otherwise, at different PLACES and TIME.

All you guru's, old wives and experts on forward and reflected powers, real
or imaginary, should bear this basic, elementary stuff in mind.

Whatever happened to your primay education?

Power, work and energy are intimately related to TIME.

The self-educated kids living in South American underground Rio sewers,
subjected to culling by armed police, reduced to making a precarious living
be selling laced cigarettes, can do better.

But don't worry about it. Just continue taking your viagra. As for me,
tonight I'm on white, dry, Bordeaux, best consumed within six months of
purchase. And the French know what they are talking about.
