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...

Don't you just love it when you're just about to go to sleep, then you accidentally discover a new scientific phenomenon
Best comment here xP
Almost exactly what happened, I couldn't fall asleep, and then discovered a new scientific phenomenon. Loved that
This what's happening now!! I'm actually trying to sleep while watching this lol
Yh same
😆😆😆
Whenever a lot of people are having a chat to the point where the room was so noisy and then suddenly everyone just stop talking to complete silence is someting that is mesmerising and scares me. It's like they/we unknowingly agree to stop talking at the same time
This happens so often in school classrooms
Omg this has happened in my classroom so many times in class and each time I think a teacher entered the room or someone did something wrong
My theory.....everyone realizes when they can no longer hear themselves talk......that it’s time to dial it back......or you all decide to lip read😁
If that happens when playing an instrument it’s usually that people have to breathe at the same time and it’s weird
and then someone farts during complete silence and it's so awkward
I am a theoretical physicist, have thought about synchronization (resonance) for many years, and still I learned from this presentation. Thank you.
couple days ago i thought about how its possible the moon always facing us and how it can not be a coincidence cause there are other moons that do the same... very interesting especially the fact with jupiters moons orbiting 1-2-4... does that mean all jupiter moons will synch up over time or only the inner 3 cause of gravity?
😂😂😂❤❤😊
@@Judas1911WR1Luna is "tidally locked" to Earth. It has nothing to do with resonance.
The entropy thing has always messed with my head. Living beings are so wonderfully complicated and an organized wonder. If things move towards disorder is that proof of intelligent design?
Just another example of coincidence?
Not a smart man by any means so it's probably just a lack of information.
@easley421 The Egyptian concept of the "Ahnk" , and the Greek version, "Cosmos" each refer to the tendency of matter toward higher levels of organization. The "life" force.
"Entropy" is the opposite, ............ death, decay....... the tendency of matter to fall into disorder.
You cannot have one without the other.
The universe must maintain it's natural balance.
Imbalance is chaos, confusion.
I hope this helps to clear up some of your confusion. 🙂
I am 75 years old and an engineer. Physics has been my favourite subject. We see physics all around us but most people do not observe and analyze. This video explained synchronisation so beautifully. I salute the makers of this video. Just loved it. 🙏
But physics isn't all around us. Physics is the product of the human mind. What we see around us is 'Phenomena' - Science(physics) being the language that humans create in order to equate our minds to that 'Phenomena'. It is a very useful tool, but if one thinks it's the only and primary way one looses much insight and understanding.

Damn bro you 75? Who let yo old ass on the internet
This channel is what the Discovery Channel was like to me when I was a child. I love how it brings life to "uninteresting" subjects.
I do agree, but I wouldn't think this synchronisation effect is uninteresting at first sight for most people
@@jinjunliu2401 but eventually we nudge thy neighbor and pretty soon TH-cam has synchronized lol
@@jinjunliu2401 I think that's why he Wrote "uninteresting" between quotation marks, he didn't mean it that hard, it's more like things that if not really well explained like discovery did, wouldn't be interesting at all because of their complexity
But as ronald says, couldn't agree more
Right!! I hope I make something of my life in the future due to these
I feel the same.
this reminds me of a phenomenon that sometimes a noisy class would simultaneously stop talking. In the short sudden silence everyone is like 'WTF', and finds out that it was a false alarm-the teacher hasn't come yet, and continues chattering.
I would assume that people synchronized their frequency in which they talked so everyone stopped at the same time and was wondering if everyone else was quiet because the teacher arrived so stopped talking as well.
But could also be just random and not related to this at all I guess
You're forgetting about the one kid that says a curse word super loud whenever this happens.
We say: "Panic spreads'". May social movements be some form of synchronisation?
@@enricogolini5376 good observation. may be.
Or when class is about to end and with seemingly no trigger (bell, timer going off, teacher dismisses class) people just simultaneously pack up and leave. It's interesting being in the class when that happens because you're like "how do I even know to do this" then the bell rings.
I went to a recording for a German TV show yesterday and I really enjoyed the sensation of when we, the audience, were clapping. We were in a circus and arranged around one circle in the middle, so I could look at people face to face, to the other side of the middle. (the show is called "Stars in der Manege" in case any German speaking person reading this wants to see it)
When music was playing we started clapping in sync, a room of over a thousand people syncronized without any instruction to do so. It happened at different paces each time, some times the irregular phase lasted longer and others we almost syncronized right away.
When we were in sync I loved looking around at a random person and no matter where my gaze went, I was in perfect sync with that person.
funny how this video showed up on my feed one day later
That's a different phenomenon though, isn't it? You guys were simply clapping to the beat of the music, right? And if I know my fellow Germans, probably on 1 and 3 ;)
@@klauskinski4060 haha, yeah!
though it also happened without the music!
Now Im going to have to look up a music concert and see if people wave their lighters in sync.
Ich bin ehrlich ich werde es nicht anschauen aber ich wünsche dir trotzdem viel erfolg!
Synchronicity!!!
Derek, I know we’ve worked together in the past so our relationship has been mostly professional, but honestly, I REALLY love your content and the outlook you give to the topics you touch. You and your team are amazing!
7:40 "if your friend is sympathetic enough "
The guy who runs fast : "On your left ! "
Oh come on!
Hey
On your left 😎
A lot of Avengers moments happened because the friends were sympathetic enough.
Oh, I got that reference.
You could have a friend very sympathetic who wouldn't slow down.
In Hungary, members of the audience purposely sync up the clapping to honor a great performance. We call it the "iron clap". After a while, it disintegrates into just random normal applause, but people will again try to sync up. It's fun and the performers love it.
.. yes - the clap speeds up, as folk hear an early clap but not a late one, till it's too fast to maintain. The Icelandic slow shout is extraordinary different, as it's not cool to be the first to shout, so it slows down, if anything. Other countries cannot reproduce it as they do not obey that single social rule. Love it :)
You don't need to start the iron clap to archive and iron clap 🤯🤯
jaja
Sometimes we do the same thing in Russia...
wait thats a hungarian-only thing?? never really thought about it and i assumed its something everyone does!
I just realized I’ve experienced synchronization with clapping. My high school did a thing at lunch where one table would start randomly clapping and others would join in until the entire lunch room was clapping. One time it got a lot louder suddenly and I figured it was just my weird hearing but I think it was synchronicity especially because we had strong coupling. My school had a bunch of groups strongly opposing each other (mostly divided by political views) but one thing that could bring all the people together was the clapping, even the most reserved groups would get in on it. Some teachers hated it cause the noise and others liked it because it was nice seeing all the students doing something collaboratively
That’s a cool story
What's interesting to me is that this "Go with the flow" sync applies not just to living things.
And the beauty of how despite how chaotical the world is, it's still so orderly.
Ordo, ab Chao
Order out of chaos
i don't want to bring any unwanted controversial topics into discussion, nor do i want to do any sort of weird theoretical 'hand waving' of natural phenomena- but what do you, personally think of Theism in the context of being a theoretical possibility?
now when i refer to 'Theism' i don't mean any specific belief system or any specific religion or any of that, i mean do you think it is possible that there's _something_ responsible for everything?
i genuinely want to beg that question, not from any desire to 'convert' you into believing something- i ask purely from a place of curiosity. i haven't personally seen any genuine scientific debate regarding Theism, and i think some actually very interesting discussion could come from it if people would set aside personal flag-waving momentarily.
i would only want to engage in such a discussion with anyone if they were comfortable in doing so, however.
@@doc______ I don't know, it seems like a big conclusion to imply that there is "something" or "someone" that is responsible for the synchronization, orderliness, etc, of the universe.
Why can't the nature of things simply be orderly? Why is spontaneous synchronization something so surprising that it could only be explained by intelligent design? And why does it have to be something "theological"? It implies that there is some sort of shadowy figure, some sort of God, that is working against the chaos of the universe to create order.
But then that begets the question, is the nature of the universe to be chaotic then?? How could you prove that? What if it's actually the other way around, what if the universe is inherently orderly and there's actually a hidden "chaos god" that puts everything into disorder? What if they're both real and they're fighting against each other? What if there's hundreds of gods out there all controlling some aspect of the universe??
The problem is, you can't prove any of these. All of this is highly abstract and immaterial. You can't show me direct proof of a god, there is no testable evidence, nothing, literally nothing at all. Maybe you can count eyewitness accounts, but again, there is no direct evidence. Sure, a christian may tell me that he felt the hand of God after praying when he did x thing, but I could follow his exact sequence of actions, and feel nothing at all! Religious evidence is not repeatable, it's something highly dependent on culture.
You can't prove that a God exists, so there's really not much point in having discussions about that topic. This is not to say that abstract topics aren't important to discuss! I admit that there's some merit to abstract discussion when it relates to artistic expression or human conscience. I can't empirically prove that a movie made me feel a certain way internally, I can't open up my brain and show you the specific electrical impulses that prove I'm thinking about eating a taco right now, but understanding these things and trying to explain them does help us understand ourselves better.
I guess I just personally don't see the point of believing in a God. I get that it can bring peace and meaning to some, I do see the importance of that. But religion really has no importance to science, at least to me personally. I understand that the existence of a God would have HUGE ramifications for, well, everything. It would completely change the way we think about the world, about people, about intelligence, about purpose and philosophy, art and politics, etc.
I get that, but there's literally no way to prove a God exists. Art gets a pass because human emotions are fairly universal, most people can agree that a sad movie is indeed "sad", and even if one particular person doesn't find the movie that tear-jerking, they can at least admit that the movie is "intended to be sad". So you can prove artistic intention, to an extent. Philosophy also get a pass somewhat, almost all philosophies follow some sort of similar logical reasoning, or they admit that they aren't the "one true philosophy" and instead accept that their philosophy is simply one specific angle to look at things, but never the whole picture.
My problem with theism is that it tries to be the "one true philosophy". It discards everything else, and shuts down any sort of criticism or examination. God is perfect and he can never be questioned, even though there is nothing to prove that. At least, that's the way I've been exposed to religion my whole life. Perhaps the actual philosophy of theism is much different from mainstream religious dogma, I wouldn't know.
There are nearly 7,500 comments so I can't imagine you'll see this, but something you might be interested in is that human hearts and breath will synchronize if two people with a close connection sit near each other and look at each other in the eyes for several minutes, or hold hands. The same happens if two people watch certain kinds of movies or listen to certain kinds of music together. It sounds very woo woo but it's true, there have been legit experiments and they will sync up, every time. Little is known about this kind of synchronization but it'd be cool to learn more about it.
Even womens periods will sync, if they share a room for months.
it's like a vibe
Would love to know more about the theory behind this. Anything you can recommend?
@@mateny.6770 Is this true?
@@laqueefasteinberg4981 Yeah. It happened to the girls in my class.
at some point i was helping out at a day camp for a bunch of kids, and on the last day, when they caught the "bad guy" they started laughing at him, and after a short while they were all just synchronized. Hearing 60 or more kids chant "ha ha, ha ha" was one of the creepiest moments of my life lmao
*ha ha ha ha ha ha*
Literally sound like a nightmare
Lol
@@pisulolol ha haha ha ha ha ha
Why u look like Rick 🤩🤩🤣🤣
10:02 I don’t think I’ll ever see this clip and not get chills, the way all these strangers just happened to all be swayed by one another to then combine into something much louder and greater is just amazing
honestly its kinda creepy idky
@@tetrapolis that’s fair, it is a bit unnerving for sure
What happened in the audience was not at all spontaneous. I'm hungarian (Budapest is the capital of Hungary) and we do this on purpose.. It's to let the actors and actresses know that the audience really liked the performance
@@noemiszilagyi6833 fair it might not have been spontaneous, but still they each altered their clapping based on those around them and not clapping to a metronome to all get in synch as we see they all start off with different frequencies
Everyone thinks they are unique until they are in a moment where they are not. They never realize it when it's happening.
I love how the music is synchronised to the animation of Jupiter's moons at 11:42. Subtle and very clever 👏!!
The quality of the videos is amazing
Yawwwwn
Because the guy who made the video is amazing 😁😁
@UC2D9jTUXWs1N6ShkcULniCA But this is 4k ;)
Yes, there is an 2160p option. But, you will use more data.

Idk, I wasn’t really feeling it.
Haha yesss
@Dyslexic Mitochondria Omg hi!! I watch ur videos. Absolutely love ur channeI. Its like a hidden gemmm
@@DyslexicMitochondria Triplets For the win
Very aphex like
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.
I was playing with my son to "Hot Wheels" circuit. We set it as a "speed ring". 2 accelerators are integrated in the middle of each straight line making the tiny cars go around indefinitely. When we tried to put several cars at the same time on the circuit, they first go randomly and after a few seconds they all synchronized ! I did some scientific studies but could not explain it ! This video did it perfectly ! 👍
5:14 conclusion: if school bands start playing on wobbly platforms we’ll finally always play in time. Even better, the longer we play the better we play in time!
There would be that one guy or girl who would have a mild case of motion sickness. It wouldn't yet matter during practice, but during the actual performance, with the added factor of stress from nervousness, that person would suddenly throw up.
@@herrakaarme and someone throwing up suddenly starts a chain reaction...
God it never stops!
@@herrakaarme kinda sounds like you talking from experience, so have you?
@@Simply_Pip Unfortunately I never played in any bands. In practice, there are also no wobbly platforms either, with the exception of boats small enough, or a storm big enough to shake a cruise ship. I have never witnessed either personally. So, no, I was just continuing the OP's joke.
@@Simply_Pip I think every American school has had atleast *one* chain vomit reaction incident
As a child I did observe that randomly people in group start walking in synchronization but could never reason it. This video was amazing tbh!
Same in school, when people start clapping. Like everyone was in sync, and I don't have any rhythm yet somehow would be clapping in sync.
Then you were wrong. It happened on that bridge only for reasons that generally never apply.
Yeah I noticed that as well. It's really weird but u know when someone is gonna speak coz u feel u wanna speak at that exact moment. It applies to movement aswell, which us why you get that awkward moment when tryna walk past someone and u both go each same way
This simplistic explanation was so immediately and intensely enlightening.
I wish I could learn other topics so easily.
As a kid, I remember hearing this noise in the middle of the night. First time i heard it, it scared the life out of me! It was loud and scary, sounded like a bear’s breath echoing through the house. But after many nights of wondering what it was, i finally discovered it was my mom and sister snoring in sync with one another. Back and forth, after hours it would eventually echo through the whole house and i swear it was something i wish i could record because it sounds impossible when i try to tell people
Womens menstral cycles synchronize, why not human snoring? Great observation RE snoring.
Nile Red saving the day with that footage
That's THE Nile Red to you lol
As soon as they started talking about oscillating chemical reactions, I was thinking about him lol
He was the first guy that came to my mind
Thank you for reminding me where I saw that video before.
I was afraid they wouldn't use his footage. The clip they started out with was pretty lame compared to Nile's.
I love how some people actively force themselves to clap in unison while others just *stop* like "whoa, somethings happening... should I be a part of this?"
Apparently that's a thing they try to do there.
You saw that guy too?! What if he just had some weird problem with clapping outta sync? Lol that ocd.
@@enchantedgamer9428 It's called the iron clap. Actors/performers usually take this as a signal to return for more rounds of bows and sometimes put on an encore that was agreed upon in case the audience is enthusiastic enough.
We do that in football
Actively? I always felt like it was a muscle memory response....
I'm glad we got to see NileRed's demonstration of the BZ clock here!
All I wanna know is how Dr. Derek creates his videos. His animations are always so appealing and on point
Order from chaos... remember when we were in school, and the teacher would leave the room and everyone would start talking? If she was gone long enough, there would come a point when as if by magic everyone would take a breath at the same time, and the room would be silent for a second.
Synchronicity!!
That comment was awesome
We'd say and angel just passed
oh my god you're right
😂
I had a 3d design class where the teacher never showed up. So kids started smoking cigarettes and chasing each other around with the blow torch. Good times.
Some kid gets in trouble and everyone goes "ooooooooooh" at the same frequency
ooooooooooh
ooooooooooh
oooooooooooh
woops
ooooooooooh
The part where he explained the hearts patterns and movements shocked me so much because I always see the weird pattern when I close my eyes but I never knew it was from the rhythm of your heart
This kind of happened in my band class the other day, we had like 5 minutes to warm up and we all started differently then suddenly the low brass started to group together then the high brass grouped together and it became this back and forth of low brass doing their warmup and the high brass doing their warmup
Wow

I have this core childhood memory of an awards ceremony at school, which we did every Friday and applauded for every award. On this day in particular for one of the awards everybody, like 200 kids, just clapped in sync as if to a beat instead of applause. The headteacher was fuming and asked whoever organised it to see her afterward, but of course nobody did, nobody organised it like that
I just noticed, the moons tidally locked with Jupiter at 11:50 make a little note and flash when they eclipse and you continued to use those notes in time with the rotations and revolutions in the music after the video moves on. That is such lovely subtle editing!
The literal music of the universe. And it's a banger too!
Synchronization even works with Walmart shoppers, when everyone ends up at the check-outs at the same time.
Chaos happens at Wally World. It would be wonderful if shoppers were in sync when pushing their frickin' carts around.
Lol nice one
So what if u use the power of synchronized metronomes to measure the spead of light ?
Yesssssssss i ageee.
I would be so mad if everyone on that bridge with me started shaking it in synchronization then got us all killed.
Everyone: Quality > Quantity
Veritasium: Quality = Quantity = Veritasium
You could say the quality has _synchronized_ with the quantity.
The experiment to see if sound can stop tumors was a frequency sweep from 0-22 something. I've been using this as a means of defense from sound pollution and acoustics associated with piracy. When using several sweeps, even with different ranges and lengths, they still synchronize at intervals.
i feel like this explains how synchronizing to a beat to a song or matching the rhythm of others in beat is done, we’re speeding up and inevitably matching each others “clock”
Can we take a moment to appreciate how much effort was put into those animations damn they explain it so well
They used Manim, same engine that 3B1B built!
Facts
pity the animator knows nothing of sinusoidal motion
So why not store that energy for power supply?
Only creators will understand. it's a lot of work even to produce a 10sec video 😏
"The crystallization in time is the phenomenon that we call synchronization"
Love that.
In a sense, two coupled pendulums are an unstable time crystal, they resist changes to their structure through time, as opposed to regular crystals resisting changes to their structure in space.

Wanted to say thanks!
Randomly talked about synchronized oscilation at a party with a friend last night, sent him this video and just watched it meself.
And for a long time now I've been thinking of logical ways to count time in my D&D Underdark setting, and not in mechanical and magical clocks/ways, and now I hear of the BZ reaction again and it's perfect!!! Drow are known for their poisons and chemical compounds, why wouldnt they have discovered chemicals that oscilate within intervalls to use to count time just like clocks!!!! This is brilliant!!!

We would move the earth 0.0000003 centimeters. And after the world would move back right after
@@nico_otte148 But if we keep jumping, it would make a pendulum with the earth, and after time, it would change everything
It would move back like right after, like it didnt happen
There would not be enough time to jump and jump again. Before it will move to its original place again.
As a Hungarian I only have one comment: the synchronized clapping is called "Vastaps" ("iron clap") and is a traditional way in Hungary to express deep admiration and appreciation for the performance on stage. As it is tradition and everyone knows it, the synchronization is not completely spontaneous - we expect it, and as soon as we hear a tiny pattern, we intentionally join in.
And I think that is his point exactly... as soon as the pattern gets recognized, everyone follows!
Yeah, it's weird to me that they used that clip. The crowd clearly did that intentionally.
That's "calling for an encore" where I come from.
@@christophersanders3252 Sort of, the crowd starts out clapping randomly. They know it will to get into sync, but there isn't any queue or signal to force the phase transition, it just ... happens.
The synchronized clapping was new to me when I first lived in Iceland, and it fascinated me for a long time as to how an entire crowd went from random clapping to synchronized clapping without any queue.
@@aoeuidhtnsnthdiueoa Rubbish! All it takes is a few people to start clapping in time louder the others and soon after everybody joins in because it's expected. This is not spontaneous at all
Great video! I noticed that there should be some logic behind resonance and synchronisation, but with your explanation I understood it right away. Thank you a lot! 👍
I learned so much in this one! Thank you for educating us while keeping it very entertaining
Me too!
yeee
Yep.
You too!
Exactly
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.
It kind of is a type of "telepathy", just not what most would recognise as "telepathy"... I believe that data like this is often transferred thru our electromagnetic fields as well... u could blindfold all these ppl and make them walk across the bridge and as long as they don't bang into each other, they will still end up doing the same thing.
We can't help what we are...
@@leighatkins22 it's just easier to walk in sync than out of sync when people are walking in crowds for a variety of reasons. Also people naturally mimic each other and generally enjoy patterned experience. No telepathy is necessary.
yes, I see you are smart here, let's be late for the lesson together))
When you have the same height and you walk the same speed you already have the same step frequency. And don't forget that you hear the other ones steps even if it is pretty subliminal. Also when you make steps your body moves up and down a bit, that you can see. And while the brain kinda stabilizes the picture of the world, another person moving up and down out of sync is noticeable. So that are already two channels of information if you pay any attention to the other person and it's not too loud.
Tbh I never cared about that.
Whereas, the more I read the comments of others, & their experience of synchronicity the more I appreciate its meaning.
Fun to see Dr. Strogatz show up here, I used some of his work in my thesis.
So is this why when somebody walks besides you in a park and you both are in sync and then you have to adjust your speed when you start to feel awkward lol

We used to have a huge house and we would play tag inside the house as a kid and you could run in a huge circle the way the rooms were set up, I am right handed I could run in a clockwise rotation and it felt right, if I ran the rooms in a counter clockwise motion it felt weird.
Derek has just dropped 3 videos in a row that are straight up next level. Quite frankly they are cinema quality. He’s hitting out the park lately. Absolutely well done sir 👏🏿👏🏿
and I clap in syncro....
I know! He has come a long way since the channel started. I think he should have had a section where he asked a bunch of random Aussies on a day out to explain synchronicity, for old times sake.
So very awesome 👏
Thank you so much for sharing all this crazy but informative information.
Love the way you guys explain things to us.
Blessings, Carlos ✝️🙏❤️😊❗️
I saw thousands of fireflies synchronizing with my own eyes, the most beautiful thing I've ever seen (here in Brazil)
Your heartbeat is perfectly synchronized with another person.....
Especially when you're Dead 😂
Since there's only 1 phase it wouldn't be synchronized. Your dead, lifeless hearts would be a constant of nothingness

Great video. I'd recommend Steven Strogatz 'SYNC" to anyone interested in the phenomenon of synchronization. It blew my mind.
When I was watching those waves through the chemical stuff, reminded me of the view of behind my eyelids every morning. I’ve also had heart attacks already and I’m not even 30. Life is so precious guys
I always wondered why audiences would start clapping together. I always figured it was the concerted effort of a group of people and people start copying to make a more deliberate clap, that I would consider to be a more enthusiastic clap for a great show. But maybe it only happens for great shows because people are clapping longer and therefore giving themselves time to synchronize? Interesting. I was always the weird kid paying attention to clapping when I was a kid. In church people often clap in sync with the music, and when I would try to clap out of sync, it was very difficult and I would keep trending towards synchronization, even though I was consciously objecting to it. This explains a lot! But I feel like it could be explored more deeply in relation to how this not only affects human psychology, but the effect of their behavior, such as analyzing economic market behavior.
You got a good head on your shoulders!
keep being inquisitive my dude
wonderful insight
The clapping in audiences like concerts, there is nothing to do with this theory. Actually is a sign to artist that the people want him/them to back to sing/play another music. Just that.
yeah, if you sing in front of an audience you can start with them clapping to the beat of your singing but end up singing to the beat of their clapping.
"Crystallization in time" that is one of the coolest phrases I've ever heard.
Tell me about it.
Legit!
Time crystals sounds like something from Sci-fi more.
Might I then recommend the very strange sci-fi book called The Crystal World
Thought the same thing. I replayed it. Saw your comment after the video. So funny.
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.
Sync and resonance is why music makes so much sense.
As a Hungarian I never tought that some people didn't clap like that, but its apparently a mostly eastern european thing. I always tought of it as a milder form of a standing ovation. And I think its absolutely not as spontaneous as people think, people might do it somewhat subconsciously, but only because its culturally ingrained, everyone did it that way since they were a kid, so they follow along. Like I never suddenly realized "wow we are clapping in sync randomly" more like "ok everyone liked the performance, I guess we are doing the syncing thing". There is always some guy that starts it by clapping slower and louder, then everyone follows, we speed up until its random again, repeat until we are bored.
I have never seen that, it seems really weird to me
This is a really interesting (to me) observation. In 50-some-odd years of participating in applauding audiences in the US, I've never experienced full synchronization, just near-miss synchronization. At which time, my instinct was to go out-of-synch. I bet there is a comparative psychology experiment in that.
@@rmdodsonbills would love to see a psychological experiment on this subject!
That's interesting. At least here in Brazil, synchronized clapping has a specific meaning - it signifies the audience's desire for an encore.
Also it's called "vastaps" (ironclap) if i'm not mistaken. Sounds funny in english
Give your animation guy a raise, he deserves it... a lot. Wonderfully done!
I agree, very talented person!
i love your videos, but this one really got me... Only this time, it was you and your son that literally made me cry. Seeing that, honestly, was so healing to my soul... That was my favorite experiment proposal ive heard in a long long time. lol
I use this video in training refrigeration technicians to understand system syncronization how small adjustments take time for their reactions.
Ibut I make them watch it as a video in teamwork, later I refrence it many times in training on the system.
This is very therapeutic video if you apply relations ships and teamwork to the lesson.
That guy he interviewed was like a mathematician, chemist, physicist, civil engineer/ architect, astronomer, medical doctor combined!
I thought: "wait a moment..... He knows about everything!" hahahha
That's called an Asian.
He's primarily a mathematician. Steven Strogatz won a Fields Medal.
Edit: He did not win a fields medal. He's just a great mathematician.
In my experience, it's pretty common for Applied Mathematicians to have at least basic knowledge of many/most other STEM fields, since that's, y'know, where the math is going to be *_applied._* Most undergrad Differential Equations courses will at least touch on things like drug distribution in the body, moving astronomical bodies, heat exchange, and yes, oscillating suspension bridges are a favorite. The collapse of the Tacoma Narrows Bridge probably came up at least 3 separate times during my undergrad career, lol.
And he’s a great author!
I watched this earlier, and I was thinking about how it relates to the concept of "sanity" and if sanity really just means synchronicity. When people get isolated they often lose their minds and become out of step with normal thinking and behavior. I wonder if it's really a question of socialization keeping people "sane" or just keeping them like other people.
It's like being given a responbility at work and must learn fast - eventually, you become less hectic and more orderly because you syncronise with the environment, and it leads to a more secure behaviour.
I guess insanity is a removal from a sense of order.
I feel this. I've been inside home 2 years only going out a little. My mind started to act weird and I am starting to work on stopping this because its not healthy
@@gabrielv.4358 Writing is helpful in this endeavor. Even if it's not organized or focused on anything in particular
@@gabrielv.4358 kinda same with the lockdowns
somehow unrelated but also kinda related: the prof in the video, Prof. Strogatz, has written a book called "sync" where he also writes about sleep cycles and how one professor was so determined to find out his own undisturbed sleep cycle that he locked himself in a bunker without any contact to the outside, no natural light sources and so on. he wanted to stay there for 7 months or so but in the end he did not last that long because he became suicidal in his last month so they ended the experiment early. So as he experimented to find out his sleep cycle without the influence of any synchronization phenomena, he lost his sanity too so to say
Nice explanations from Dr Strogatz, we used his book in my nonlinear dynamics course.
I've felt how a bridge wobbles once.. I almost tripped myself experiencing it. It wobbles more everytime a vehicle pass through the bridge. I didn't understand how it happened. I'm glad I found this video!
The editting skill is just outstanding
thanks
Hi
Ikr
wtf
@@pixeldestroyer6434 you edit this
I’ve always noticed as a kid, walking along side someone for long enough uninterrupted and you’ll notice your legs are naturally in sync. Or while on the swings, I’ve noticed you end up swinging the same as the person next to you.
Two people walking in sync makes it easier to talk and also less likely to shoulder bump into each other. Swinging and talking is the same reason . Swinging the same without conversation could be an unconscious "competition " of sorts? From what I've seen in playgrounds, younger kids will swing however they want and just yell to their friend but at an "older" age they'll swing together to talk.
@@jayceewedmak9524 when we were little kids we always ended up swinging together
@@deadmanswife3625 We're both right. If kids stay on the swing long enough they eventually swing together or one grabs the rope on the other swing, collide then keep chatting lol. I remember being young, watching my kids when young and now watching my grandkids. 😊 swings are great fun
@@jayceewedmak9524 oh my goodness you just jogged my memory. Remember when the other person would grab the Rope on your swing?
@@deadmanswife3625 best part of swinging with someone lol even if you clunked heads or fell off or jammed knees and fingers 😆 it was all fair game in the playground 😉
We talked about this stuff in my differential equations class! A couple chem majors got us into the lab and showed us the BZ reaction, it was super cool
Amazing phenomenon, super work to get it to us. Thank you ❤️
I don’t think I’d be able to contain my laughter if I was in an audience where our clapping synchronized
Wait until the laughter starts synchronizing too
@@skytec1811 omg I love this
From what I have seen, synchronized clapping doesn't just happen - there is a purpose behind it. With synchronized clapping, the audience is asking for an encore or curtain call by the performers, and it only takes a few people to start it. Interestingly, the beat in synchronized clapping is almost always considerably slower than regular applause - I wonder what the explanation for that might be.
Really? Weird because it kind of creeped me out for some reason...
Yeah it's not completely a coincidence. Once you hear people clapping in unison, which means they really liked the show, you either join in to signal you also enjoyed it, or you stop clapping if you didn't like it that much.

Everything is connected. The properties of the whole can be understand trough the heart, holism and harmonisation which all interconnect. Its like applying a higher level of empathy not only to other individuals but to the existance itself.
People who are making these videos are really doing good Job. God bless them. Understanding Science becomes much easier when we take a closer look at our surroundings.
Steven Strogatz looks so excited when explaining what happened to the bridge. That is the feeling all great teachers try to instill in their students!
I felt his excitement for his field, too! It was very engaging.
Yeah feel it too. Hope have teacher like that
Actual critical thinking
Strogatz is awesome. His textbook "Nonlinear dynamics and Chaos" is a true joy to read. All you need to start is a little bit of differentiation and matrix algebra.
I arrogantly chuckled at the fact that all those people were walking in unison, then realized I just chuckled in unison with a bunch of random people on the internet.
Dang
You have just succinctly explained the TH-cam algorithm
That's too funny, good for you catching yourself!

Your show is fascinating. I’m glad that TH-cam showed me your channel.
Love how there's just random clips of Derek nodding when the other man is talking.
As a video editor, this is a pretty standard thing to do to break up the video. Fun fact: sometimes the same shot of someone nodding is used over and over again because it's convenient and people won't notice!
It's to emphasize the interaction that is going on despite one person talking 95% of the time.
Why do you think he's wearing a headphone.
Yes but do they happen in a synchronized pattern?
@@pe5erbarnes the editors think we don't notice but we do, every time. Stop pls

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.
He is a gem
He talked about physics, chemistry, and civil engineering with equal ease.
He da man
especially a professor that specifically said that he likes to study complex system
I loved it, except for the runners allegory. The runners synchronising their speed is intelligence, not some automatically running principle.
