[Vision2020] Pendulum waves

[Kenneth Marcy]

From the science demonstrators at Harvard comes this video of fifteen uncoupled 
simple pendulums of monotonically increasing lengths that dance together to 
produce visual traveling waves, standing waves, beating, and (seemingly) 
random motion.

Of the various visual configurations do notice that the three-dimensional 
helical structure that is inherent in genetic and reproductive molecules makes 
an obvious appearance. Physics, not religion, is what we need to know.
