Pendulum Waves

    The period of one complete cycle of the dance is 60 seconds. The length of the longest pendulum has been adjusted so that it executes 51 oscillations in this 60 second period. The length of each successive shorter pendulum is carefully adjusted so that it executes one additional oscillation in this period. Thus, the 15th pendulum (shortest) undergoes 65 oscillations. When all 15 pendulums are started together, they quickly fall out of sync—their relative phases continuously change because of their different periods of oscillation. However, after 60 seconds they will all have executed an integral number of oscillations and be back in sync again at that instant, ready to repeat the dance.
  2. awesome to watch!
  3. Haven't seen that one for a while. I really enjoyed watching all the various synchronisations that occur throughout. I understand that the simple harmonic motion only truly occurs at angles of less than 5 degrees from vertical?
  4. WOW! I had a gsx11 like that once...

    Seriously - physics is awesome! You want to know how and why things work? ...
