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

  • God is amazing

  • Lightening bugs not fire flies

  • That is absolutely MIND BOGGLING سبحان الله

  • Veritasium, can we please agree there is no experimental proof for entropy. If entropy is proven wrong over and over experimentally, if planets form from stars and organic life cycles thru life and death, exchanging disordered matter to then reorder. If we can consume elements like minerals and via enzymes convert them in to living cells then entropy is NOT REAL. Just the same as medicine, dogma exists. Entropy I hear over and over to explain time flowing in one direction... you don't need entropy!

  • 21 minutes to explain this? You should be ashamed.

  • In Rotterdam a big bridge nearly collapsed when there was a dance parade and people where all jumping at the same time

  • 12th standard education i guess

  • Quality video!

  • Human was a Metronom too.

  • Reality is more fascinating than any theory. The magic attributed to the unanimated world is like a veil that prevents people to see its actual reality.And sometimes people becomes frustrated and even irritated when it is explained in simpler terms. The best example I know about it is when the great English poet Milton said Newton had removed the magic of the rainbow after Newton’s explanation of light.

  • 0:28 . GOD

  • 7:30 you can do better than that

  • 👍🏻

  • So we could eliminate traffic jams by using wobbly roads? I'm pretty sure those traffic jams are the only event ignoring the laws of physics.

  • Ethereum

  • So youre telling me that there will be a point of time that the entire people on earth will say the same thing or walk or jump the same?

  • 6:06 I can't be the only one seeing an army of marching swordsmen?

  • I'm surprised Huygens didn't intuit and anticipate or at least immediately understand the cause of this effect. Had he never seen how pendulums in different forms synchronize on a ship, or in a carriage, or even when you are just out walking and things hang off of you? Why would pendulums hanging from clocks be any different? O_o Maybe I'm a physics savant, who just never studied physics. Or maybe Huygens had an off day at work :P Edit: Seriously, how do people not immediately just see how this works? What causes the effect? I am starting to think I've wasted my youth in the wrong career. No need for fancy explanations. The more a pendulum moves on an angle to gravity, the more it pulls whatever it is tethered to out of place. Simple so far, right? One could delve into it, but I think most who have used a swing can intuit it. When a swing is at the top, it can pull the whole swing frame out of place. Okay... So when a swing is at the top, it transfers energy to the frame it is tethered to. The frame then shifts perpendicularly to the ground. The shifting frame will transfer energy to other pendulums attached to it. The more parallelly to the ground a pendulum is moving, the more of the energy that the beam transfers to it results in movement because the frame is moving completely parallelly to the ground. If the pendulum is moving at 45 degrees to the ground, half of the energy transferred to it will be directed towards the ground, and just result in friction. The other half will result in movement along the axis that the pendulum is moving. The frame transfers energy from pendulums moving perpendicularly to the ground to pendulums moving parallelly to the ground. The more perpendicular and parallel the motions are, the greater the effect. So energy is transferred until the pendulums are in sync. The pendulums don't even have to be influencing the frame they are attached to to sync up. It is enough that the frame is moving fairly rhythmically, like from wind or waves. Pretty sure that is by far the biggest factor for pendulums on ships, for instance. Huygens, you n00b.

  • And it relys on the fact they all are the same. If one was bigger or smaller it wouldn't work. There is a lesson here.

  • When you look att the the turn signal on two different cars when they have stopped due to a traffic light. These turn signals will also synchronise. How come?

  • That's not Huygens, that's Dave Mustaine.

  • I see turn signal lights on cars Synchronize randomly

  • The whole University has synchronicity. It has to do with the Rythm of The Spirit we are living in.

  • LMAO THIS WAS ON A STATE TEST! Thank you for making educational, yet interesting content! Pretty sure they used the same sources you did.

  • Nothing beats the ancient civilizations' innovation which last thousand years

  • Firefly populations in different locations around Tennessee, if memory serves, light up in waves.

  • The 2 clocks synchronize because it's love!

  • The videos are so satisfying to watch

  • We don’t really have to go back 350 years.

  • Humans. Don't get me started. As the herd of we primates fell into step, a perfectly reasonable way to move in a dense crowd -- Hello, army! -- they set up a dangerous resonance in the bridge structure, something the engineers had not anticipated. They should have studied human herds, amd the military, before drawing up the structure. During the American Civil War, and I imagine in all the wars of humanity whenever a pontoon bridge was laid over a body of water, the troops were instructed to break route step, and just shamble randomly over, like any crowd in a street. Resonance has long been noted for its destructive properties, (see earthquakes, wind and Galloping Gerty, the Tacoma Narrows Bridge failure) but I think, forgotten for its positive properties, both physical and mental. And for anyone who reads this and gets a redass about it, we are all primates, the alleged greatest of the great apes. Sometimes we act like that ... sometimes not so much. We contain both.

  • To answer 19:30; Almighty God's Word!

  • I am a scientists and this blows me away

  • So this is how we solve the "measuring unidirectional speed of light" problem? We use this principle to synchronize the clocks of the detectors

  • I went to a performance in Denmark once, and at the end people were applauding, each at their own pace but then they all went in sync and it was scary as

  • People who dislike this: n0, only chaos

  • Love that he puts sponsor stuff at the end of the video

  • Trying to remind ourselves of our cosmic existence, one day we will all meet again

  • 👍

  • ok metronomes on a wobbly surface and light bugs. And..... the whole universe. No just no

  • Inertial equilibrium.

  • This is probably how Nikola Tesla would wanted to get his Tesla towers in sync. Earth being the wooden bar.

  • In this age of high technology, physics still manages to mystify us. Nicola Tesla indeed was on to something when he cane up with the earthquake machine. 🕵

  • I really liked this. But what I liked the most is that it took some simple and obvious things we take for granted, and offered some profound insight. Thank you.

  • This is how democracy was born. The majority wins. The minority must follow afterward

  • It is waves. Waves always equalize.

  • Part of this phenomenon has to be caused by the human mind though, right? Not everything is as synchronized as it appears, and we humans like finding patterns in things that don't really have patterns

  • It's because they're all part of the same single body that they eventually oscillate as a single body.

  • Brilliant, brilliant! And a quality video! Keep it up my man!

  • seeing veritasium's HD face after that bald guy with the bad webcam is kind of terrifying

  • Does increasing the number of metronomes increase the consistency of the timing?

  • Out of the way so amazed it's like a room full of girls when they start hanging out together they start synchronizing on their menstrual cycle that fun

  • This channel makes the best videos ever!!!!

  • nature's Natural Feedback loop seems to propagate throughout our reality created over our natural humanistic existence expressed by some who have been acute to the feedback as a religious phenomena throughout the world. Our natural pendulum of life and death is especially perceived at death of a human system while during our life time some-we are sensitive to the humanistic experience as a whole called a civilization... realized as a moral pendulum written through out written history... Peace and Love always

  • If there were 70 men marching, 60 of them fell and 20 of them were injured who were the extra 10 that were injured?

  • My god... I love this channel

  • Explanation of why the one changes motion (after 5:44)is flawed.The arrows are drawn the wrong way. The TOTAL of the two that het in sync first will balance out with the counter motion of the platform, but that don't mean that the platform doesn't move. And the move of the platform is forced by the two that are synced already. Be cause of which it dominates the one that is still doing is own thing.

  • Synchronicity is interesting and there are more syncs... cause each spectrum(world) has an own balance...as much balance,as much syncs...so the question is which balance we choose, which sync?Thatswhy parallel waves are important,we must choose our own balance then recognize the parallels and keeping the line...if we are in higher balance we learn but we get left behind or must try more times not to get left behind...if we are in lower balance we get not our results of our works...so choosing which sync is parallel is very important...and not each sync is available everywhere...even in universe there are more balances...and there are more universes... basically we must find the parallel outside what we are already exactly inside... mostly people are choosing lower or upper nivou balance than themselves...but it's a good school in upper nivous to getting some knowledge or rolling in the deep to leaving the inner suffering behind...this channel has a good nivou.

  • 2:16 the wrong acceleration on the pendulum is driving me crazy

  • Nature is actually shockingly orderly. It prefers it in fact. Its why we see it everywhere and why "random chance" cannot in any fathomable sense explain our very existence.

  • And as it is appointed unto men once to die, but after this the judgment: (Heb 9:27 KJV) |>~~~~~~

  • hey man, i was thinking....if the synchronization works atleast with a solid connection(clocks kept on same surface or something like that) , wouldn't this solve the basic issue we had while we were trying to measure speed of light!!.....since the clocks were unable to synchronize then....we couldn't measure the speed of light in one way....but using these nomes....if we first set them up and let them synchronize over time (which they will eventually)....won't then will be able to measure speed of light in both(hence different) directions! possible or not...do let me know please!

  • Is this what happens when you are at a red light and watch the turn signal of the car in front of you sync with your turn signal?

  • The Earth is flat.

  • Wow, so like, when you live in a fake country that only enables people to hate on each other, and outsource jobs, and covers everything in asphalt, grueling traffic, and remote strip malls w/junk food, then you will end up w/people walking in a sick, twisted, 'entitled' destructive, hurtful cadence. **So saying "Oh well, that's your choice, then" is a bunk term, no?**

  • We just think it's disorder because we're too small to see the whole thing.

  • 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!

    • Well it WAS the british army.

  • 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. 😔
