The Secret of Synchronization

How does order spontaneously arise out of chaos? This video is sponsored by Kiwico - go to www.kiwico.com/Veritasium50 for 50% off your first month of any crate.
An enormous thanks to Prof. Steven Strogatz - this video would not have been possible without him. Much of the script-writing was inspired and informed by his wonderful book Sync, and his 2004 TED talk. He is a giant in this field, and has literally written the book on chaos, complexity, and synchronization. It was hard to find a paper in this field that Steven (or one of his students) didn't contribute to. His Podcast "The Joy of X" is wonderful - please listen and subscribe wherever you get your podcasts www.quantamagazine.org/tag/the-joy-of-x

    I can tell you what happend with the bridge, THE BRITISH BUILT IT LMAO. Just like when the British army and Navy tried to take the states and they were beatin down by basic farmers and ended up tucking tail and sailing away. Or kinda like how they couldn't take Ireland and Scotland and all they literally had was mountain people and farmers, the Brits once again had a full army with horses, archers, swords, and actual armor. And still the Brits ended up running home. Or any point of ww1 or ww2 before the us got involved the Brits were literally getting beaten like little school girls lol. I mean come on in ww2 they were running away from the Germans so fast they made it all the way to Dunkirk. The British navy was so pathetic civilian boats had to pick up soilders cause all their navy ships were sunk by U boats. You look through British timeline and there are no real achievements for a long long long long long time. Just disappointment, and settling for things that people will give you. Like that very very tiny little island you guys are on lol. I dont trust anything designed or built there and especially not both. But hey on the bright side you guys do have fish and chips which I hate but you guys seem to like them so that's good, and with the generations of constant bombardment of heart shattering eat a bullet disappointment you have learned to put away some serious alcohol, so congratulations for that atleast

    I feel like this could become the non-intrusive way to reverse cancer as a vibrational frequency or from a tiny enough electrical pulsation... just like the cells each by molecular structure somewhat have their own IP address. The key might be to record such a frequency from the top 5000 healthiest people, maybe determined through their athletic performances.

    Hmmm... if two metronomes are perfectly opposiite in sync.. wouldn't that be an equilibrium? Also... if a 3rd metronome was added that was perfectly between sync of the other two (not sure if this would be possible maybe 2, 3 or 4 would be needed, I haven't given it enough thought and don't have the time right now I have an exam tmw) if perfectly in between the others, wouldn't it or thm stay perfectly in sync due to balance... if it's balanced I don't understand why one would choose to move independently without the same happening to the others and constantly staying out of sync.. but out of sync in such a way that they're equally spaced in timing.. ?

    How to understand properties of the whole by understanding the properties of the parts??. I guess simulations. But simulating walking of 167 people would take incredible computers. So more simulations to try out after done with designing. Wait it means making better graphic cards which would mean having better games. Ig. Lol

    I'm not sure how people in other countries clap but in Hungary in theatres it is a tradition to syncronise the claps after a period of chaos. Therefore I'm not surprised that a clip from the Hungarian capital, Budapest has been found for this demonstration. The lenght of the chaotic clapping depends on how good the play was. After that period, people begin to think "OK, this play doesnt deserve a longer chaotic part, lets change to the another frequency" and began to clap on that also traditional frequency. People then consciously syncronising to people seating nearby already clapping like that. Nobody directs that but it is also not accidental, we await the syncronisation part. We work similar to those lighting bugs actually :).

    What about objects that synchronize even though they aren't coupled? i.e. Peoples car blinkers synchronizing at a stop light. Or is that different since in that case it synchronizes only for a moment then goes back to being out of synch? This is probably answered in the video ill keep watching lol.

    Dear Sir, Thank you for this both brilliant and informative information. Lived in Italy Sardinia last century and heard Cricket insects finally combining their chirping in unison. Was akin to me like the B/W audience 'clapping' bit and frequency. By-the-way, as a kid did this experiment whereby you suspend a length of string horizontal between 2 chairs (any lenght or hight ) and then tie 2 another vertical strings anyplace onto the horizontal and tie a raw potatoe on each end of the downward bit and set them rocking out of motion. 'Hey Presto' they always rock finally in unison in the end despite the lengths of and variables . Makes sense the Millenum bridge across the Thames river bit. Take care. David U.K.

    The discussion about the 2 clocks “synchronizing” 180 out of phase (3:00 thru 4:30) reminded me of something I witnessed a few years ago. Two of my grandsons (roughly aged 3 and 4 years old) somehow managed to wrestle two 6’ stepladders onto a trampoline. When I stumbled upon the scene they were both 1/2 way up their stepladders and bouncing on the trampoline 180 degrees out of phase (when one was highest in the air the other was lowest on the trampolines downward stretch). As dangerous as it appeared, it was at the same time fascinating. I can’t help but think that somehow they managed, without thinking about it, the same kind of synchronous movement achieved by the two pendulum clocks. I didn’t want to startle them and calmly asked them to stop. I was equally amazed when they managed to stop, climb off the ladders and make their way to the ground without falling. I was relieved and proud all at the same time. 😊🤷‍♂️ Now 17 and 18 years old, neither has any memory of it.

    Those Kiwico kits sound great. I don't have kids buy like those kind of toys. A few years ago I gave a kit of a interlocking wood frame that made a dinosaur and it had an electric motor that gave it motion - The idea was he and his father would build the thing together. (it was age appropriate). One night dad starts t build it without him and completely messes it up - apparently he can't follow instructions. The moral is an interested parent is as much part of the equation as a cool toy.
