Don,
There is a lot of material to digest.
People who are well versed in the mathematical properties of waves probably
don't find any of this astonishing, but until I watched the video of moving
moire beats I didn't know beats could move backwards relative to the
direction of the motion of the und
You ever see a wheel turn backwards from the direction of the vehicle on a
movie?

Yes, I have noticed wagon wheels turning in the "wrong" direction in
movies. Since wheels do not really behave like this the phenomena of
backward moving beats is usually classified as an optical artifact with no
deep significance for physics. However, the black and white stripes of the
moire beat
Harry, I see a great visual example! Thank you.
But now my brain is interfering.
What about light beams with a beat frequency that's a forward motion?
The 'pattern' would move superluminally forward in the interfering beams.
So, if superluminal moire interference beats are an abstract
rela
Thank you.
The design of experiments and inventions are guided by theories and
paradigms. I do not know enough about the technique or the theory behind
laser cooling to relate them to my visualization. Obviously the theory
works but that doesn't mean the paradigmatic concepts which gave rise to
