Pendulum Waves
Fifteen uncoupled simple pendulums of monotonically increasing lengths dance together to produce visual traveling waves, standing waves, beating, and (seemingly) random motion.

My first thought was that there are beautiful and mysteriously powerful forces at play in this physical world. After reading how this device was precisely engineered to mathematical standards, well it is no less beautiful and mysterious. Blessed are the recent generations of humanity who have acquired the understanding and knowledge of these forces.
I would love to have the plans and measurements so I could build one of these.
Thanks for that. For years I've used that office toy - the five pendulums in a row - to explain for every action there is an equal and opposite reaction, and that people's action too often reflect physics. I was not thinking creatively enough. Instead of stopping our own reaction to a negative one, we need to have a beautiful positive one. I am expanded. naomi
