Metronomes syncronizing

This seems magic to me, that all of these devices, unattached, would so quickly synchronize with each other.

  1. There is a moment where one metronome tries to get out of sync, but is quickly resynchronised. Resistance is futile……

  2. In the 64 version there is one, 4th from the left, 2nd from behind, that is off-beat, but it’s eventually dragged along by the others.

  3. Niklaus Pfirsig says:

    It’s actually simple and obvious.
    First, consider the metronome’s design:
    A pendulum is mounted on a shaft attached to a spring mechanism designed to keep the pendulum centered. To overcome energy losses, an escapement mechanism releases a little energy from a mainspring to compensate for energy losses. An adjustable counterweight on the pendulum sets the resonance frequency.

    As the pendulum swings from side to side, the rest of the metronome is pushed in the opposite direction (Newton’s 3rd law). This motion is transferred to the platform as longitudinal waves The waves that are least in phase cancel out, while those c;loser in phase reinforce other waves, imparting a swinging motion to he platform. This swinging motion causes mass dampening on the out of phase metronomes,modifying their pendulum’s motion to match the ones in sync.
    By the time the metronomes are synced, the motion of the platform can be observed. pay attention to the out of focus lettering on the right side of the platform.

  4. Not if they are chaotic đŸ˜‰
