    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/th...

Ever since I was a child, I've noticed that when people walk together, they end up walking with synchronized steps. I thought it was some kind of telepathy or, at least, a no-verbal communication. I never realized it is actually a phenomenon in physics and chemistry.

I have never once noticed this, and anytime I've paid attention to it the steps have not been synchronized. You'd have to have the same length legs, be going exactly the same speed, and actually care that the other person looks more stable to you. I usually look at the ground while walking.

@leighatkins22 it may happen because of "emotional contagion": where one picks up the emotional state of those close by. I was a carer for an elderly man who'd had a series of mini strokes and his short term memory didn't function. He was almost permanently in a "in the moment" mental state, like a sort of mindfullness. I would pick up his mental state, he was very pleasant to be around. In my regular job I occasionally have to deal with quite agitated people in toxic mental states. It's unpleasant, I can recognise myself start to be polluted by it and can, to an extent, retain my equanimity. I'm fairly well inured to being polluted by toxic mental states now.

Breaking lockstep or cadence is hard. I noticed this during my many years in the Army. Going from double time to quick time march, brings a formation into lockstep extremely fast. Run to walk is what this means. A group of SMs (Service Members) just casually walking is in lockstep. That being drilled into your head day after day and year after year….is a habit not so easily broken. Kinda impressed more Brit SMs didn’t cause bridge collapses.

@Astrobrant2 Maybe the speed of the music. I just read about a theory of difference between men and women and how certain types of music impacts their speed and behavior while driving. So why not walking? In your case it makes me think of power walking to high intensity workout music.

Buddy, That probably applies to musicians as well. I've caught myself mentally relating my footsteps to a musical tempo. Powers of two dominate my rhythms. When I was young and ran a quarter mile or more, I would breathe in rhythm with my feet (every four steps). When that wasn't enough I would change it to every three steps. Just think waltz! It really seemed to make the running easier. I also went to a quasi-military school for 11 years -- lots of marching -- and was in the band. If anybody unconsciously does things in cadence, it's me. That said, I really don't find myself walking in lockstep with other people unless it was when holding my wife's hand. However, my left foot is permanently on an odd number. IOW, if I'm walking in beat with some music, I almost _can't_ have my left foot on an even beat. Funny thing, though, if I'm walking when walking-speed music is playing, I actually consciously force myself to walk at a different pace. I don't know why.

I have always been amazed when I synchronize with a complete stranger going to work in the morning on a consistent yet intermittent basis. I am referring to the situation where you are on your way to work in your car and you come to a four-way stop sign and this person is in their car and they stop at the same intersection at the same time as you--on a somewhat regular basis. It does not happen every morning but it happens often enough to where you easily recognized their car with a certain level of expectation. You do not know this person, you do not know where they live, but we are both going through similar rituals every morning...alarms going off, showering-up, making coffee, getting dressed, grabbing your stuff and heading out the door....starting your car....adjusting the seat belt, getting the radio tuned and Bamm... within the window of a half second you both pull up to the same four-way stop. You are heading North and they are heading West. Amazing synchronicity.

This makes me think of quantum entanglement and how maybe the reason it happens is because there is a shared field in a higher dimension from which the atoms "hang" and serves as a way to transfer information. Just like the table serves as a medium for transferring information here

I like the way you think! You are close, but there doesn't need to be higher dimensions if you apply time field theory. you end up with 4 dimensions, but you also get 4 time feilds...the time feilds themselves are basically universal constants that occupy real physical space that everything is bound and ordered by. The fixed dimensions of the electron shell, the surface area of a black hole, this size of an atom...all of those are universally fixed by the time feilds...and because Universal fundamental laws and properties of the universe change from one time field to the next...you end up with things like quantum mechanics and general relativity never being able to be mathematically congruent. They don't need to be though, there is a far simpler explanation. Quantum entanglement happens at an instant across any distance...it is a universal constant of the 2d quantum time field...and because we live at a causal and relativistic scale, a 4d universe, we get things like superposition and every quantum measurement at best only being a probabilistic in nature. Ive been working on this for almost a decade and think maybe I need to publish a paper.

Yes... and they tell us that if you can't see or believe in something it doesn't exist... Ever heard of ur electromagnetic field? Electricity 101 says if u pass a current thru a wire, an electromagnetic field will establish around that wire. Transformer Principle 101 says if u place another wire in that already established electromagnetic field, a current will be induced to flow thru that one as well. And if u modulate the current thru that 1st wire, the current induced in the 2nd wire will reflect the modulation pattern in the 1st wire, perfectly - in other words, data will be transmitted thru that electromagnetic conduit, without either wire touching each other. Our bodies run on electricity - our brain functions, our heart function, all our muscle structure, we are electrical beings, and as such we must also have an electromagnetic field around us - what tree-hugging hippies call an 'aura', and as transformer principle tells us, data can also be transmitted quite successfully thru that aura. Therefore, as an electrical being, u can sit next to someone and not even see them, yet on some level, u will trade data with them... ever wondered how it is that u can sit near someone u don't know, and not speak to them or even make eye contact with them, yet they will give u the creeps?!? This is ur intuition tuning into the data u've received via ur electromagnetic field, and u've been doing it all ur life, u just didnt know it coz u've taken it for granted. And I strongly suspect it is responsible for phenomena like critical mass and alot of that other social behaviour we are seeing here as well, especially when it comes to moving together as a single unit social mass.

One summer evening, in Pennsylvania, I was witness to a huge cloud of lightening bugs, against a pastel sky, at sunset. Additionally, up on a hill, the chimes of a church played a melodious hymn, which tune floated over the small town. The gentle pace of the hymn was synchronized with the lighting of the bugs, as they kept a beat. It was a magical moment, that I wish I could've captured on video..

I used to practice jumping into lock step say, with my dad or someone I was walking and talking with. Walking while holding hands, I found, is another way of being in synchrony! It's a lot like drumming in a big circle and locking up with a synchronous rhythm with everyone else. It is amazing to experience the sudden coalescence and to even introduce a new movement and feel the effect it has on the whole group.

@Ian Wallace Chaos as the opposite of synchronization is an extremely limited definition. Ultimately, it is emergent randomness, the opposite of contingency. I argue that this is an illusion, due to limited consciousness. Finis.

Chaos the distribution and synchronization the order, two sides of the same expression. A natural emergent property of relative position. Luck is synchronous interaction at the half step, bad luck the asynchronous punch out of phase with your motion. Hence why bad luck feels like getting punched in the stomach and everything grinding to a halt while good luck feels like riding a wave already going your way. Just that said system includes every variance of perspective both possible and imaginary that leads to it being hard to deliberately synch up with. Also why discordant action on purpose creates further collision of waves rippling outward from the initial incident. The kind stuff you do kind of have to approach polymath areas of interest to spot as a pattern so try not to judge too harshly the oblivious among us.

Thank you, very well produced video. Much comes to mind, including a basic observation I had 30 years ago or so. It seems at almost everything, no matter how big or small (i.e., atomic or galactic), behaves in either a cyclic or rhythmic way. Many energy waves, as they travel through space (sound, radio, light, etc.) are rhythmic. I'm not formally well educated on much of this stuff, so don't know if there are some energies that travel in a straight line. Anyone who knows, feel free to comment. Your vid emphasized synchronization between a broad variety of individuals in a group. But it seems almost everything in the universe has its own established rhythm, which might be the same phenomenon, only with the subcomponents within an individual. An individual sound wave can only exist ("survive") if it's regular. If the crests (correct term for the outer limit of the wave?) of a wave changes, one of its primary defining characteristics (other than still being defined as sound) changes. IOW, it becomes something distinctly different from its former self. I'm just thinking this out real time as I write, so I may be off, but inspired (by your vid). Which I believe presented itself visually at 30 or so FPS via the laptop screen. When I was a kid, I noticed that water flowing from our garden hose down the sloped concrete of our driveway, formed waves. The concrete was (relatively) smooth, surely with no such similar wave pattern on it, so the waves formation was obviously attributable to some other element of fluid dynamics, I believe it's called. While knowing specifically why waves form would be nice, it was mostly the observation that they formed period that had me start to see how almost everything (if not literally everything) is rhythmic/cyclic. And if we don't think it is, maybe it's only because of our lives are a nanosecond on the universe's time scale. That, or some other element of our limited capacities to perceive, that have us physically unable to detect the cycle In astrophysics, the collective opinion among those in the field might be that 13.6 or so billion years ago, there was a mega-monster sized ball...just hanging out. You know, as it had for all of eternity until that point. Okay, so that's impossible, for one thing. Existence of anything, even empty space is impossible. It's impossible that that phat mega ball of matter was simply "always there". Something had to create it. It's impossible that there was ever a beginning. While I have a personal, experienced-based belief in a higher power I call God (for convenience), He/It is no exception. It's impossible that God, if there is one (I respect that my beliefs are not facts), has always been. Popular religion doesn't explain their conception of God. Saying "He's always been", or whatever is claimed, doesn't explain anything. It's just a way of moving on from that which can't be explained. So God, time, space, and all matter (and anti-matter), as I see, could never have the power to create itself from pure nothingness (meaning not even space, entirely void of even the small subatomic particle, exists). God...sorry, but while certain life experiences and "feelings" (the kind of feeling that...feels, or senses) have me believe you may be lurkin', I can't believe you created yourself. You might be omnipotent, but that'd only be after the fact. It'd impossible to for you to even have the thought "Hey, I want to exist" if you don't yet. Okay, so we've established that it's impossible for anything, including empty space to exist. With that in mind, the purely confident statement of truth I believe is entirely accurate, is: Something's going on. Moving on from that, since there's so much evidence that everything adheres to a cycle, then the universe must as well. I believe astrophysicists' popular theory is that the universe is expanding. If so, then I'd guess that expansion is only one phase of its cycle. It either expands so much it reconvenes on the other side of infinite space, or some other cosmic phenomenon causes it to eventually reverse from expanding to contracting, eventually causing it to all collect again, via the mega-ultra-as-big-as-the universe-plus-some, super duper massive black hole, which gets us back to that same phat and jiggly ball. Which in turn, probably hangs in that state for a few, until it gets either bored and/or antsy, increasing its baseline jigglyness, until it gets a hot under the collar (I might get a hair ticked off too if I was just floating in the middle of nowhere, for like 80 octillion years), heats up, causing all the atomic friction we like so much, until it just can't take it no more, and...BAM. You might see where I'm headed here. So, I submit, that everything, every element of existence, even mental (the guy with the headphones mentioned something about psychological processes...or something cognitive processes based) doesn't merely "acquire" a cycle, as the result of its existence. I propose that it may be the foundation or the source or precursor to its existence. Mike Myers (Austin Powers), who was once an SNL cast member, played a Scottish merchant character. In the skit he would say, "If it's not Scottish, it's CRAP!". I'm pretty darn close to feeling the same way about a cyclic precursor or foundational matrix being the only thing that matters...everything else (except maybe Scottish made materials and consumer products)...is CRAP! Okay, I kind of lost there for a minute, but don't blame me. The vid did it. It inspired free thinking and that can happen. In fact, while I haven't done a formal trend analysis, it might happen at regular intervals. Even if they were irregular intervals, they're still intervals. And again, we might just need to pull back a half a hair more, and like displayed depiction of a beating heart, it's a regular rhythm, it has unique patterns, peaks, blips an' stuff...within each beat cycle. So maybe my aforementioned loss of sanity is just as essential as the Yin is to the Yang. One defines the other. Insanity is defined by its opposite. That's kiiind of another subject, but I would like to say, if you'll permit me, that maybe I wasn't speaking pure gibberish when speaking of the impossibility of anything. 'Cause let's face it. For anything to exist, it has to also not exist. IOW, if the entire universe was "chair", and there was nothing else, we wouldn't really thinking straight if we called the only thing that exists "chair" (the thing we humans invented to sit on). It's the fact that a chair doesn't exist that allows it to exist. Sense exists only because nonsense exists. And it might get interesting here: Space might only be able to exist if it also doesn't exist. As I said...my base concrete statement containing what I believe to be the highest definition of the word "fact", is that...something's going on. It's no new theory that maybe nothing exists outside my mind. My mind and cognitive thought processes might have created the whole of the universe. Or...I might just be dreaming. Hey...when I hit they hay at night and dream, with only one exception, I don't even consider that I'm dreaming during the dream. The dream is just life. But when I wake up, it's...oh, I was dreaming, and am so convinced I've awoken to actual life, I don't often consider it to be anything else. But with the understanding that obviously our minds are sophisticated enough to create what we perceive as "reality", so well that we don't even suspect differently, then that A) says a lot about our mind's capacity to fool us, time and time again, and B) Has us consider that what we think of as "life" might be just another level of dream state. It could be when we "die", we simply return to a state of being that doesn't surprise us in the slightest...just like we're not surprised when waking from a nightly dream. Which brings me to the psychological mention of the gentlemen with headphones. It supports a consideration that I've had for many years. That A) Reincarnation, *may* a thing. or B) Not so much reincarnation, but whatever's responsible for me consciously living this life, perceived internally. IOW, I sometimes wonder why the world isn't exactly the way it is, only me (Terry), am not experiencing Terry's life from his internal perspective. I wasn't any of the uncountable people who lived in the past (to my recollection, at least), so what is it that's attributable for me consciously living and looking out past these eyeballs at life, from the inside? Since that question's not easy to answer, I'd like to conclude with another proposal. Since my internal perception of Terry's life is the basis for my only confident pure truth statement, that something's going on, it's not too much of a stretch to consider that...if this internal conscious perception of Terry's life has *definitely* occurred, why might it not happen again? I don't know much about a soul or spirit that came from and returns to some afterlife homebase. So I'm not saying my consideration is based on that. I'm only saying...since it's happening now, with this conscious experience of life and the awareness that I'm aware of it (well said, I know), then simply based on the logic that since it's proven that it can and does happen, then...according to the universal laws of probability, might be somewhere between likely and guaranteed to happen...again.

There is a fascinating implementation of this concept in high end mechanical watchmaking. There is essentially two mechanisms (escapements) which synchronize and theoretically serve to divide errors in ratekeeping. The F.P. Journe Chronometre Resonance is my favorite example. Unfortunately, one will set you back about as much as a nice American home.

So this is kind of like how natural magnets get magnetized right? All of the atoms have their magnetic poles sync up due to, say, a strong electric field passing by. The difference in their random-seeming orientations cancel any macro-scale magnetism out, while the moment they line up it's like a state change where the macro object is now a magnet. I could be wrong, but it seems very similar

One of my favorite things to do in school was in gym class, while we were learning about basketball. There were 30 kids in my elementary school gym class and every one of us had a ball. When doing dribbling exercises, I noticed this phenomenon for the first time, and I was kind of amazed that no one else had paid attention to it. When everyone sort of locked in sync, I purposely broke the sync and went against the flow. Interestingly, even though I broke the synchronicity, eventually so did everyone else; but what truly threw me for a loop was when everyone starting synchronizing with MY pattern instead of coupling to someone else's. Even if you try to purposely break the system, it just adapts, and it's no great wonder that the good professor Strogatz loves the concept so much, it's truly incredible that it permeates every facet of nature and synchronicity is almost integral to the universe.

Veritasium and Smarter Every Day are so good because they are so passionate about learning and passionate about the things they talk about. I was homeschooled up until last couple years of high school. At home I basically taught myself and I was able to focus on the things that excite me and watch videos like this, I dived deep into math and science while avoiding literature and social studies. At USA public school the teachers have a lot more to deal with than just learning. They are dealing with the social aspect of teenagers, and the curriculum that they have to come up with for everybody to pass and expose each person to everything. Science at school was so boring but then they could also fit in literature and social studies. At high school there is some flexibility for people that like learning but it's still quite rigid to a basic curriculum. Not many kids at my high school cared about learning, maybe 30%, the rest just wanted to get it over with. Public school isn't about passion, it's about getting people good enough to get a job and live in society. I went to college and it was the same attitude. Probably only 70% of the people in college wanted to learn, the rest just wanted the degree to get a job, or just did it because it's a social norm and raises your status in society. In college there were people in my program that only passed because the school doesn't want failing people because it reflects negatively on the school, even when those people didn't earn the degree. I hate public school but I also realize we have millions of people that need jobs, push them through school and the kids that enjoy learning have to do it on their own time.

School isn't designed to educate, it's to pacify and indoctrinate. People have been warning about this for a long time, but look at our technology. Students have access to anything they want, but the books (which tax payers pay for) are not online, they aren't freely available, parents aren't able to easily find out what their children are being taught. When I was in school learning high school math, the books were terrible. Examples always were expressed with trivial examples - like the associative property would be demonstrated like so: (1+1)+1 = 1+(1+1) I hated those books. The example constantly used 1's and 0's to "explain" a property, but the numbers they chose allowed multiple interpretations of what was happening. like this would be a derivative example: d(x) = 1 or d(x^2) = 2x but a better example would have been d(3x^8) = 16x^7 The last example demonstrates that the derivative of cx^n = c*nx^(n-1) But they would NEVER have complex examples so it was difficult for many students to understand what was going on. The books were purposely written poorly in my opinion. My grandmother was a teacher, and I had access to books SHE used to teach calculus - they are INFINITELY better.

I wonder if a cruise ships dampening system, that reacts to cancel out sway, could be used to eliminate bridge sway issues? Water tanks on either side of a section of bridge could work passively or actively. We'd need to treat the bridge as if it had several sections with a dampening system for each one. Perhaps all the tanks could be linked together so the water weight is shared and could be redistributed as needed? The presence of water ballast tanks on a bridge section would already provide some dampening of vibration as it would simply be absorbed by the water inside the tanks. But once sway was introduced the water would resist that sway while an active gyroscopic system could respond faster and more precisely.

"In science we do reductionism, all of our science courses tell us the way to solve a problem is to break it down into smaller parts and analyze the parts. And that has been phenomenally successful for every branch of science. But the great frontier in science today is what happens when you try to go back to put the parts together to understand the whole. That's the field of complex systems. That's why we don't understand the immune system very well. We don't understand consciousness very well. It seems like the whole is more than the sum of the parts. How can you understand the properties of the whole given the properties of the parts?" Using science as it is today using reductionism, you can't understand the properties of the whole given the properties of the parts. Most people think science can explain everything, especially the scientists, including the immune system and consciousness. But they're WRONG. We cannot understand consciousness by thinking of it as a byproduct of neural activity in the brain. Instead, it could be that the brain is the organism through which consciousness is processed.

@Mario Ramirez If you mean how they started the swaying of the bridge, then I'm not entirely certain. I would guess that since the bridge was quite populated, people are bound to walk at the same pace or else they'd bump into one another or stepping on other people constantly. And that coincided with the bridge's naturally frequency and it all went downhill from there.

@Mario Ramirez In the case of the bridge, it's not that people affecting each other. It's the people affecting the bridge, then the bridge affecting the people. And the cycle repeats until the bridge collapses, which, thankfully, was stopped before that happened. Once enough people walk on it to exert a certain amount of sideways energy to the bridge, the bridge starts swaying. People don't have to be in sync for this, so long as there are enough forces being put down to start the process. The video had data showing once 156 people were on the bridge, the bridge starts to sway. When the starts swaying, people will want to maintain their own balance and naturally adjust their own steps to match the motion of the bridge. This further amplifies the swaying.

@george hill one question I didn't understand tho, how would that apply on a person and the synchronization that happens when two people travel together. Does the brain somehow transfer energy to the other person in order to be in a similar pace? Or is there another explanation?

I experienced the synchronized clap one time at band camp and I thought that was really neat. This video explains so much about why that probably happened. Very cool. 😎

here's my theory: each time one of them ticks while another one is out of sync, it causes a very slight delay in the next tick of the others that aren't in sync, eventually leading to them all ticking at the same time. i should've watched the whole vid, you explained this literally 30 seconds later lol. and instead of a delay you described it as a "kick", so my guess was the opposite of what was occuring

i like the representation of the first seconds of the video, cuz... you know people tend think that fast thinkers are smarter then the individuals that do things less faster, but point what they miss is that it doesnt matter how fast we figure out things, we tend to think like that, but what comes in place is that less fast thinkers are more adaptive ans creative and the more they train their growth tend to go really slow, but then keep raising and growing, like exponencials and in the end they can overgrow the others with knowledge that sometimes can be even crazy, that scares the others and so they tend think these people are crazy, but only because they themselves are scared of potential creativness of people, thats the way how math works, motivation is a key and many times they will fall, but every time they stand up the, also grow a bit more, and the more steps the more falls but the way we learn the pattern of failing gonna grow with the fails, so they simply have to understand thats it not about how many successes u got but how mamy times did u fail and stand up again with determination to stand up again even if it would be even harder...

topic in video, good. show global earth is, for me funny, because i know why these things happen for years. youtube, 2019 : not want wrong infos about, ( gave 4 example ), sandy hook ( school shooting ), miracle healing and ? flat earth ( talk about shape ) and holocaust ( world war, many horrible deaths ). to compare the last 2, say much about this, world. but enjoy this video and have a good day, in the, hell-i.o.-centric world-view, as it is called. - with, big bang and evolutionary -theories. ( and i thought, make such theories is not good ;) ).

Very interesting demonstration with clear explanations for the observed phenomena. I know this is nitpicking, but I was disappointed with the animations which show pendulums swinging is a very un-natural manner. I wish these animations were more realistic, because they detract from the overall presentation.

Professor Strogatz really carried the whole video! I like how good he is at making extremely clear, simple, and easy to understand explanations. It's something you don't see very often with professors that study such complicated subjects.

Strogatz actually wrote a textbook on differential equations that my college prof used in class. It reads just as clearly as he talks here, and actually contains several of the examples discussed in this video when the topic of synchronization comes up.

It doesn't really explain anything though. Runners can decide to synchronise or not, metronomes can't decide that. There are not metronome friendships. I just thought it was misleading

@Fabian Huber Yeah, but the same mechanism still applies. There's some natural speed for each runner, and there's an interaction between them that can influence their behavior. This example indeed is quite convoluted and could easily work differently, but it happens to work and actually operate under the same model.

Any number of metronomes will all appear to synchronize for a short time. This would only be amazing if they stayed synchronized.

I have always wondered about the aplause thing. I speculated, that it must be a custom or something, so when one guy (thats me) claps out of sync, he would stick out and was afraid of other people's judgement, so then he just conforms.

What would happen if the metronomes were at different tempos? 2:3 ratios, 1:2 ratios. Can we combine the metronome and orbital resonance questions?

So what crazy is that if you put 100 metronomes on a platform, 50 perfectly synced with each and the other 50 equally synced but opposite of the first 50 in movement, they wouldn't sync.
