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

no joke, this video gave me an idea for my phd ... see you at the nobel prize
"So you naturally expect universe to be "Messi" " --mybrain
Remember when you were in the school lunch room and everyone happened to finish a sentence at the same time, causing a weird silence?
0:30 does this solve special cases of the N-body problem?
I wonder how the metronomes would react if they were placed on a platform resting on steel balls. And then more when the metronomes are in a circle ...
2:20 I really thought it was the Minecraft music at first.
1:15 good heavens! the army learned a lesson and nobody died? A Miracle!
You all understand the immune system perfectly well how to diminish as many people as you possibly can, thus to reduce their immunity to Cancers and all types of fatal diseases within the herd of The unwanted, useless eaters
Everyone who take civil engineering understands the World is Flat. The building of Bridges railroad tracks, and canals, confirm this.
I noticed synchronization with turn signals with cars at a turning lane any explanation to that???
Great video as usual! I'm from Hungary and we call that type of clapping "vastaps" seen from 9:40, in English that would be "iron clapping". Just a fun fact ;)
The thing is energy distribution becomes equal
15:01 Him: that's not a fart.... crap! ... 19:02 I have been sitting in my own poop to far to long now.
vsauce or this channel?
We're with you all the way against Twitter bro.
Question: do the slower ones catch up, or do the faster ones slow down? to which one do the others "fall in line" to? lets say you have 1=2bpm, 2=4bpm and 3=6bpm, which one would they sync up to?
Simple answer, God
Not sure how true it is, but my friend once mentioned periods among group of girls tend to synchronize over time.
Great Video Derek.
People clapping probably doesn't count. Too much opportunity for minds to get involved. If their hearing weren't a factor, then a better argument could be made. Anyway, good video.
The firefly phenomenon reminds me of how people sync their breathing with other people
2:01 they just want to cross from other side of the bridge
I and my ex talked about this. She said it's because of god's will or kind like that. I said science. Yeah, we broke up.
This is science
For that metronome experiment you said that it is regardless of number of metronomes. I mean that how many metronomes doesn't matter. But is it regardless of the size of platform too? I mean the relative size of metronome and platform?
WOW
fun with beer cans? I have a fun with 2 X 4s program. Hahaha.
Your videos are really amaZingggg
Damn, if you put several rocket engines together instead of big one, imagining a disaster will happen.
Me, an Assassin's Creed enthusiast: How can it be a secret you just climb on top of a high building and press V... Then miss the haystack and fall to your death
Hello Turing instabilities
18:03 here's the answer
The people on the bridge are simply reacting to sway so that makes them all moving sync it's no secret
can we use the kuramoto model to calculate the one way speed of light?
I wish I was born smarter. 😔
How the heart muscle works in spirals is amazingly beautiful to me.
Who waits to get on a long line that’s wobbly like that? And you brits call us americans crazy.
This went from neat physics phenomena to woowoo real fast.
We call nature disorder just because we dont understand how nature really works
Your entire channel is at jeopardy because Bill Gates is behind creating COVID-19 virus. It is a man-made virus and for somebody to predict that only a few years before it came out is too coincidental. And now ironically he is helping support in creating a vaccine. Follow the money!
I don’t mean to sound like a know it all but other then the advanced mathematical equations which I won’t pretend to understand but some of these interactions seem to have be pretty obvious.
07:07 In class this would be the exact moment when I stop understanding what the teacher is talking about
Acaso con las mentes de las personas no sucede lo mismo? Cuando la mayoría cree en algo terminan arrastrando al resto!!!!....como si entraran en sincronía
It’s a very interesting video.
Everyone who studies complex system should read about dialectal thinking, very helpful
👍🏽👍🏽

Y ¿Cómo se puede explicar que en las residencias estudiantiles de chicas, o en una casa donde viven varias mujeres, se suele ver que ellas sincronizan las menstuación? Aunque ellas lleguen en diferntes fechas, y con la menstruación en otro período, al poco tiempo entran en sincronía. A veces hay excepciones
And how can it be explained that in student residences for girls, or in a house where several women live, it is usually seen that they synchronize their periods? Although they arrive on different dates, and with menstruation in another period, soon after they come into sync
12:40 cc: not facilitatory but "oscillatory"
Can synchronisation can be used on emotions ? Since empathy is the reproduction of an emotion we percieve
What would happen if all those random particles that pop in and out of our existence all popped into our existence at the same time? Would they throw the entire universe into chaos?

Wasn't that the Big Bang?
This was a fantastic video. Really interesting content, interesing guest and excellent quality
My mans really said longitude with a hard g
Does that mean we’re drifting away far into space?
This is part of the secret to extremely high efficiency motors/generators.
Chaos is an illusion of the scale of order. There is only order that only seems like chaos.
this is a frequency entropy
I've been pondering the orbital resonance of Jupiter's Galilean moons for years in my head. Now I finally understand how and why. Thanks.
Which one is first? And what general frequency would gather the rest?
To me, this was one of the best and most inspiring episodes of Veritasium. Great work, thanks!
10:59 does that mean that eventually our earth will only show one side to the sun?
Amazing video. However I feel the video missed a huge potential in relating to the final point about complex systems.
How can a bridge have a resonant frequency?
Put metrinoms in diffrent direcyions plz .we want to see
Amazing video.
so you can use synchronisation to mesure the speed of light (your previous vidéo)
"It was only a few decades ago that scientists started fleshing out a rigorous theory of synchronization." I don't believe that because it seems too easy. Framework of proof (for pendulums on a common movable platform, but this can easily be generalized): (1) Assuming there were 1 pendulum only, express the effect of the movement of the 1 pendulum on the movement of the platform. (2) Express effect of the movement of n asynchronous pendulums on the movement of the platform. (3) Express the effect of the movement of the platform on the movement of a pendulum. (4) From 2 and 3, generate a system of equations for the cases with 1 and 2 pendulums. (5) Solve for the equilibrium in a case with 1 and 2 pendulums, with arbitrary starting values. (6) Show that the equilibrium does not change if you add 1 pendulum, regardless of the current number of pendulums. Alternate proof framework: (1) Prove that regardless of current state after one period an apparatus with 2 pendulums is closer to synchronous equilibrium by more than some fraction of the present distance to the synchronous equilibrium. (2) Prove that for an arbitrary number of pendulums by induction. (3) Prove that the sequence of distance to synchronous equilibrium indexed by period asymptotes to the 0.
Yet at a concert when people use lighters or flashlights to swing left and right with there arms, nobody ever gets in sync...
Does free will really exist?
si con estos ejemplos enseñaran en el colegio todo seria distinto pero no lo hacen solo hacen ver todo lo aburrido q es la fisica
Aristoteles says that to reach God there are 3 paths, beauty, justice and kindness ... Beauty = Harmony = Synchronization=Cosmos...
"Christian Hoidgens" - difficult
Mind blowing 🧖🏻
Momentum of swinging is slowing down time to time, you, dumb human! Gravity slow it down and it’s time, you dumb! Put an electric quart pendulum clock, you will see the difference.
Romans were the first that brakes steps..... I Romani sono stati i primi a rompere il passo quando attraversavano i ponti.
Reminds me of the conquest of Jericho
WHERE'S THE NEXT PART OF THE VIDEO???
15:02
THIS IS WHERE THE SCIENCE HAS MADE A BIG MISTAKE. ANALYZING ANYTHING IS FINE BUT YOU WILL NEVER UNDERSTAND THE INTERACTIONS OF EACH SEGMENT WITH ONE ANOTHER. MAGNETIC SYNCHRONIZATION IS THE EXACT REASON THAT YOUR CHILDREN ARE BORN TO YOUR FAMILY. SCIENCE HAS A LONG WAY TO GO. BUT I MUST SAY YOUR VIDEOS ARE OUTSTANDING.
Synchronization is very fundamental, it's wonderful!. This is far unlike the cacophony of modern physics.
Bridge looks like Tacoma narrows galloping gertie. It collapsed
Genuinely fascinating, thank you!
this channel is my favorite element
Excellent subject for getting people interested in physics :) I have been doing these things in all my life, but I'm no NLdron..lol
Sir I wanna meet u and work with
This would happen in my school where people would start banging on the lunch tables during lunch in the time of "We Will Rock You" and we would eventually get the entire lunchroom synchronized slamming on the tables doing "We Will Rock You". Good times.
The way he says pendulum and longitude shouldn't be as infuriating as it is
So with the fireflies. Has anybody tried to make them flash in a way that's against there normal patterns. If they just tried and match there surrounding group flies, then they all sync. Could you trick them into a sync patterns.

says to a pre programed beat flash, off, flash flash, off, flash, off,
Pendular clocks work by the still not understanded "waves of gravity-force". A wave tries to syncronizice the moving system.
Nature is beauty and beauty is order. What we are observing in so called is the dissolution of one thing before it's remade into another. The hatred of ourselves, because we don't understand the order, is why we also disrespect nature.
Summary: PHYSICS
We are in a dome, there is no planets, just Nasa CGI. That's where you lost me when you ignored flat earth and pushed outer space bs.
What is an idea ?? How an idea is born ??
I literally clicked on this video just because I saw it on the NLdron India Trending Page, and my NLdron recommendations are literally filled with his videos from around 6 years ago.
The universe is constantly changing & is not set in stone & as new parameters are added to the equation we will find the answers change. It is chaos & order combined and there is no definite answer to anything as it is relative to the individual observing it.
Good one
Great video! However, I really dislike the clickbaity title "Secret of Synchronization"... What damn secret?
