Let me give you my "Mental Model."

There is no such thing as "cold."
There is no such thing as "heat." (there is infrared radiation--i.e. a
frequency(s) of vibration of atoms)
Cold is the absence of heat, absolute cold (absolute zero) is a single
measurement of one state of heat (vibration/movement of atomic
particles)--NONE!
Heat (hot) is really a measurement of the state of exicted
atomic/sub-atomic
particles movement, and of that movement producing "heat" through the
friction produced by the movement of these atomic particles...

Next, there is no such thing as "time!" Time is simply a measurement of
movement! Indeed, our time is based on the rotation of the sun and
planets... (atomic time on the decay of a radioactive substance--but
again,
physical change and movement!)

I realize that specific "mental models" have been created, taught, adopted
and followed (too religiously if you ask me!) for discussing and
describing
"radio." However, most of these are far from "real things!"

Warmest regards,
John


Well, John,
If you put it thataway. Heat is an abstraction of movement. And time is
an abstraction of movement. Looks like the common thing here is ... lets see
.... hmmm... abstractions ! couldn't be movement, cuz my dial don't move
anymore - the LED's just flash the numbers. Antenna length is an abstraction
of movement - the rate of movement (mhz) (megacycles per second) uhoh - I
can see a circular reference here --- if speed is rate of movement - then
rate has no meaning without including an element of time -- which is itself
an abstraction of movement.
move us toward a better understanding - lets do string theory next -
unless it moves, too.
