The shaking table, or base plate, is not a non-moving mass, but is the
coupling factor which transfers the energy from the sum of all the other moving
masses from the strongest to the weaker. Another example of majority rule, if
you will.

Coupled oscillators can do very interesting things above and beyond simple

Look at the circuit at the bottom of this page with 5 cross-connected neon

Hi
Yes, the settling in is fractal and the path taken to sync isn't the same
every time.
For a simple way to look at multiple coupled clocks go back to old style
filter theory:
1) You have some number of resonators
2) You have some set of coupling coefficients between the resonators
3) You
The math I am familiar with, seems to have mostly developed around
master-slave arrangements associated with radar pulses and (as you point
out) TV. In the MIT Rad Lab series there are some single-purpose treatments
but a good summary is Millman Taub, Pulse and Digital Circuits. Their
approach is
A frame-by-frame analysis of the metronome video could show the frequency
and phase of each of the 32 metronomes as a function of time.
Is there a non-youtube version of the video using a well-characterized
video format? I'm not sure I would trust the youtube video codecs to keep
time correctly,
Hi
Google Orbital Resonance. The same process works for *very* large systems,
and you can lock at interesting ratios like 2:3 or 1:2:4 in addition to 1:1.

Funny when I go to the links and read about the subject, time seems to slowww
down
By the way, googling microwave weed burner to find this article turned
up another application of microwave heating for a very different kind of
weed.

Maybe not. We need the math that describes the phenomenon, but it
won't come from me.
Consider the way that television sync pulses synchronized the sweep
oscillators. The pulse has to get there before the oscillator cycles
on its own. Similarly, the movement of the common base has to occur
before
Not true. It depends on the strength and reciprocity of the coupling.
If essentially equal as with the metronomes which are coupled pendulums
(the math exists for this), the systems will come to some combination
frequency, though as has been mentioned in a many-oscillator system
there may be
slow the fewer
ones down, or speed the fewer ones up.
