Double Pendulum: chaotic motion from a simple assembly of two physical pendulums (one attached to the end of the other) with the energy of the system moving frenetically back and forth between the potential energy of gravity to the kinetic energy of motion.…

Lorenz found an elegant way to analyze the dynamics on his strange attractor. Looking at the time series of z, he noticed that each local maximum of z seemed to predict the next. He plotted this and his data falls on a curve, which we call the Lorenz map.…
