Default "SO COOL" says the nerd in me....

I know TK will love this.....

I tried to explain/show it to the family and sadly, they just dont get it....
Please tell me someone else thinks this is cool....





If you place 32 metronomes on a static object and set them rocking out of phase with one another, they will remain that way indefinitely. Place them on a moveable surface, however, and something very interesting (and very mesmerizing) happens.

The metronomes in this video fall into the latter camp. Energy from the motion of one ticking metronome can affect the motion of every metronome around it, while the motion of every other metronome affects the motion of our original metronome right back. All this inter-metranome "communication" is facilitated by the board, which serves as an energetic intermediary between all the metronomes that rest upon its surface. The metronomes in this video (which are really just pendulums, or, if you want to get really technical, oscillators) are said to be "coupled."

The math and physics surrounding coupled oscillators are actually relevant to a variety of scientific phenomena, including the transfer of sound and thermal conductivity.

That is so epic! I am going to have to show and ask some of my teachers about this! Thanks for sharing.

That's really cool! And when they all start going the same way except for the 2nd one on the far right you're sitting here going "come on, get in step with everyone else"

Loved it! My fave was the one that wouldn't conform for awhile.

Now I wonder, if this was done on a hard wood table, would the same thing happen, just in greater time? Would be interesting to test out. Might drive my family crazy though LOL
