As an addendum to our earlier presentation, Vibrationdata presents another physics masterpiece. Watch as three metronomes set at slightly different rates around 192 beats per minute go from chaos to complete and perfect synchronization. Coupled only by a meter stick resting on two soda cans, this demonstrates science at its greatest.

  • cool. 

  • Is this similar to how entanglement works?

  • @stl517 hello! read my comment fully before commenting! I said loudly that it was NOT "ID" becase someone had earler said "omg! it makes me beleive in ID". I in fact explained the thing a little bit...

  • @shoonnya It is not intelligent design it's true. Pendulums have been around for centuries.

    However, synchronized oscillators (the interaction of more than one pendulum for example) have only been studied in earnest for the last 50 years or so.  What is really remarkable is that this phenomenon of synching is based on very simple rules.

  • Omg I m now addicted to the tick tick tick tick tick tick...

  • Christiaan Huygens would have enjoyed this demonstration of entrainment. Imagine a circle with a hundred or so aligned along tangents to the perimeter, all happily ticking away, until one is is displaced, rotated or removed. Maybe gyroscopes aligning their precessions?

    Fun Stuff, thanks.

  • If you put metronomes that are already in sync on top of cans of beer, they "un-synchronize"

  • jkeagle13, what would happen if you started all 3 metronomes at the same frequency and the initial phases used in this video? The initial phases in this video correspond to a mode of a 3 mass compound oscillator right? If they all had the same frequency would they maintain the initial phase relationship? Maybe my question is why use slightly different frequencies?

    hahahahaha nice one ^^
