Wouldn’t like to watch Stoner’s one after a few schmokes……

Awesome.

I’d rather not look at his one in any state of mind.

Is it just me or does that one of Ropers look kind of like some weird futuristic gun? 😯 😕 Quite cool, starts off a bit slooooow though…

The second one looks like something from Dr Who

ah good old simple harmonic motion in a coupled system

🙂

I like the top vid the second one just bored me.

Cool! Chaos->order->chaos->repeat

Can’t help but think of the maths behind that. Takes me back…

Cool vid. I love BoingBoing!

why do they do that in stoners clip?
Looks cool but why dont they just swing back and foth uniformly?
I can have a complex explantion but not with actual maths or equations

pendulum timing is a function of length, so because they are staggered lengths they change their relative positions over time. Theyre nicely sorted so that the come back to the original arrangement after 60s.

theres more at the boingboing link I put in the OP.

did not notice the length [feels dumb] but yes mesmerising
I suspect I will be wasting some time away tomorro watching those links with the kids
Cheers

You having ‘shmokey time’ by any chance?

with my kids NO
dont think you need to be a stoner [ pun intended yet not at all apt for OP]to appreciate that
