Wouldn't this work with any set of dominos? Or is there a minimum ratio of thickness to height for this to work?

thanks dude youre genius

great channel shame it doesn't have any more subs than this.

Or "sonimod" as we call it

Hagen von Eitzen

Apparently one should start with the bircks slightly furthre apart than their length (21 cm), so that errors (slipping, rotation) do not stop the back wave. More than sqrt(21^2+6^2)=21.84 would be bad cause then the bricks would fall through in the first wave Seems there is only little leeway ... (not to mention that more than 21+6 would stop the first wave).

Just use real dominoes

cJonah

This feels like a good analogy for the sums of infinite series, somehow, but I can't quite put my finger on it…like, an infinite domino line will have no double domino "result"…idk, I just feel like there's something there.

Here the experiment is done with real construction https://www.facebook.com/roar.bruun/posts/10155484798014758?notif_t=close_friend_activity¬if_id=1497271847359594

Now I wanna try this irl

I'll steal the bricks from Trump's wall

Thats sick

OK big fucking deal.

Well, not quite a perfect double-domino effect... But definitely a solid Parker double-domino effect.

Pegasoes

Not quite sure what I'm doing wrong here (assuming Matt isn't doing something wrong in the vid), but... When I calculate the bit the bricks connect (the yellow bit at 3:05), I get 0.88cm What I do is: the diagonal (the line over the ground, between the two corners of the bricks) is 21cm. The short side of the bottom brick is 6cm. So the long side (bottom of the top brick) should be: sqrt(21² - 6²) = 20.12cm The little bit that is touching the bottom brick would then be: 21 - 20.12 = 0.88cm So, what am I doing wrong?

this is what I'm looking for

nice

classic parker square

2:22 - 3:13 this must be what English sounds like to non English speakers.

The beggining was a classical Parker Square of all double domino effects...

what an amazing noise

Matt Parker to be the next Doctor!!

Now make a calculator out of bricks

Michel Sakakini

Please spare us with the algebra

Mac Wack

Satisfying.

Wobbuffet0

beautiful geometry

Александр Багмутов

And the first brick never stops moving, until it on the ground! (If we oversee technical issues) It have very complex path, in which upwards and downwards motion, probably, alternates. (At least for some brick sizes)

AntsyBird

I feel like this effect could be applied to something practical... but I don't know what yet...

Wood 'n' Stuff w/ Steve French

Pretty cool!

Fergus Maclachlan

0:49 And this, ladies and gentlemen, is the kind of thinking that led to the Parker Square.

bernardo rtgy

wow that experiment was awesome!! nicely explained as well and easy to understand even for a Brazilian like me

Connman

why u gotta take somwthing cool and ruin it with math

TheMasterboi1

its like freeing a trie data structure using recursion. pretty cool

Toys and Fun for Kids

:o I dislike math. I was good at it but i disliked it.

Philip W

I was trying to find angles of triangles the other day at work and since I'm many decades removed from my last geometry class I couldn't remember how. Now I know and I am so pleased.

champo865

if you set them down, to turn them up, to dominos them to set them down? why bother?

FullTimeSlacker

Why is the hypotenuse not the length of the brick?

arturo garcia

U lost me at geometry

StringDeposit

just discovered your channel. enquiry like this fires my neurons . great to be on board.

GD Awesome

Aww... I thought this was just gonna be simple Pythag, but nooooo

borstenpinsel

Now the real question is: can you start an independent line of dominoes with the "back draft". It looks nice but that's about it. Would be cool if you run into a t-junction. One half runs while the other does not. Everyone disappointed. Then it starts "going back" starting the other half. :)

With just dominoes I don't see a way but what if the first brick falls onto a trigger of some kind only when it can fall flush with the ground

Byron Ruhter

I am absolutely enthralled with Matt Parker's lectures and demonstrations. I hope he continues indefinitely on YouTube. The lesson on falling through the earth was outstanding as are all of his projects.
