Awesome Youtube videos

Hey! That's pretty cool ... but it really more made me feel COMPELLED to drill scales in triplets until I feel like barfing. :/

It sort of reminded me of the intro to Hot for Teacher by Van Halen.

If I can make just one person barf then my time spent here on Earth would not have been in vain.

I'd like to teach the world to sing...oh, forget it.

You just ruined the next 6 months of my life. I will be training the dog now.

not a youtube video, but wanted to share this,

WTF?!?!? I don't get it?!?!?!

Why do they all sync when he puts them on the cans?!?!?

I'm so confused?

It's because every action has an equal and opposite reaction. Each metronome pushes against the surface it's sitting on, which in turn pushes against the other metronomes, which causes them to sync up, even with slightly different frequencies (basically they resonate against each other).

Sometimes when doing that experiment, one or two of them ends up going in the exact opposite direction, because that's a much less stable oscillation that still works out (but then as soon as one of the metronomes gets slightly perturbed that usually causes that stability to be broken).

The cans just make the synchronization happen faster; even if they were sitting on a steady table they'd still synchronize eventually. This is also why in old-fashioned clock shops, if there's a wall full of pendulum clocks they'll all tend to be swinging at the same time (because walls aren't perfectly rigid either).

Ok. Fair enough.

I must admit I was expecting the board to start moving and roll off the table or something. I was thinkiing of of soldiers having to break step when marching over a suspension bridge so it doesn't shake to pieces.

That would be cool. A whole lot of metronomes on a model suspension bridge making it collapse. Or a whole lot more metronomes covering the actual Golden Gate bridge and making it bounce! That would make a cool youtube video.

The Mythbusters tried this a few times and haven't yet actually gotten an experiment that worked at all well or showed anything remotely like what was actually going on.



My feeling is that if the resonance of a marching formation can cause a bridge to break, that same bridge would also be broken by the wind (such as what happened with the Tacoma Narrows bridge). Also, if a formation were to cross a bridge in a way that just happens to resonate sufficiently to cause a collapse, they wouldn't be able to keep on moving because of the very same sympathetic vibrations that are taking place.

Basically I don't think that the breaking-step thing has any basis in reality (but neither do a lot of military "truths").

This is the guy who's been doing the tile in my kitchen remodel.

They have others, but this just works so well...

But it is a "fact" taught in Structural Mechanics 101 in civil engineering schools around the world! That is where I learnt it.

What the hell is wrong with the drummer? lmao.

[roymond]

I've needed me some FILDI and Ze Frank for a while...

Dunno, Rone, he kinda reminded me of you...

[rone rivendale]

I was almost offended by your words Spud, and then I realized it took you 3 days to come up with that.

[drë]

don't you dare take my fucking headphones off!

Cool! That's the Cobble Hill Health Center in my hood in Brooklyn. Also, Oliver Sachs is awesome.

Rocking. Had this spirit been evident in the early 80s, my experience as a classical guitarist would have been very different (also, had I known Ani Difranco)...
