We probably should move this off list...
But, yes, the 'donuts on a rope' is often interpreted as a PDE (but not a
PDA :-) ). Although it's damn peculiar even for a PDE. Hmmm... I'll have
to put that in my "interesting problems to tackle someday" journal -- it
should be possible to do a quick & dirty calculation and see just how
energetic those 'pops' have to be to keep the thing moving at an average
speed of, say, Mach 7. My gut feeling is that it would be one hell of a
bumpy ride...
