The professor and the pendulums. We know what will happen when one pendulum swings. But two? 'Oxford Mathematicians and their Toys', episode three, starring Jon Chapman (and the pendulums).

@jon_ox Just think of how this is going to revolutionize trebuchet warfare!

@jon_ox What a crime to bring up the “last loop” bit, then cut the video short before it had a chance. 😆

@jon_ox I have watched this video 5 times: and each time the pendulum repeats the same pattern. A tet⁴ computer would solve the three-body problem.

@jon_ox That is friggin' awesome.

@jon_ox Qs: Why is Time Period of a pendulum constant? What does motion of pendulum establish about motion on planet Earth?

@jon_ox Things are getting chaotic 😵‍💫👀

@jon_ox Very nice demo

@jon_ox 😂

@jon_ox Is it analogous to a "positive feedback" system?
