How does order spontaneously arise out of chaos? This video is sponsored by Kiwico - go to www.kiwico.com/Veritasium50 for 50% off your first month of any crate.

An enormous thanks to Prof. Steven Strogatz - this video would not have been possible without him. Much of the script-writing was inspired and informed by his wonderful book Sync, and his 2004 TED talk. He is a giant in this field, and has literally written the book on chaos, complexity, and synchronization. It was hard to find a paper in this field that Steven (or one of his students) didn't contribute to. His Podcast "The Joy of X" is wonderful - please listen and subscribe wherever you get your podcasts www.quantamagazine.org/tag/th...

Equal but opposite steps should cancel out, but, human error, or inherent need for normalcy, unifies the resonance, there by increasing the oscillation. Therefore, it can be postulated that the angle of the dangle, is in direct response to the beat of the feet. Ha ha ha !

Does anybody ever notice something similar to this when you are sitting behind multiple cars stopped in a turn lane at night? The random directionals will sync up every ten seconds or so. I tend to get entranced by this if I'm sitting there for a long time. Maybe I'm just weird.

The part where the hungarians were clapping, we actually have a cultural thing with synchronized clapping at shows, I think it's about signaling the perfomer to start the show or to come back for an encore. It could be a case of that.

15:18 when people are walking that close together, they usually look downwards to see where the legs of the person in front of them are, so they won't kick or step on them. This causes people to take steps in sync with the person in front of them. When a person in front of you steps forward with their right leg, their left leg is left behind and will be in your way if you try to step forward with your left leg. So you will decide to step forward with your left leg when the person in front of you steps forward with their left leg so you can walk at the same speed without kicking them

19:22 absolutely, it's what I immediately try to do when learning something new. As I'm taking the information in, it's immediately being compared to and merged into a streaming simulation, testing where it fits in, how it interacts with individual components of preexisting systems and then integrated into the hierarchy. I wouldn't feel comfortable even repeating something until I can reliably recreate it's interactively in the grand system with ease.

The people on the bridge were probably compensating their walk with the sway of the bridge, making the sway worse and making more people catching their balance more and more and more.. Thus, the bridge was poorly engineered to begin with.

whats really interesting is if you look at the metronomes = individual minds the platform = social media/youtube/twitch The cans = recomendation algorythm then you get influence. Any body else have random algorythm / mind syc or even new subscription vid sync with your own thoughts. Do recomendation algorythms need some kind of dampening disipator to decouple minds.

Women who live together synchronize their menstrual cycles. Also, if a stallion is put near a mare who is not in estrus (heat), she will short-cycle and change her cycle to come into estrus a bit earlier.

Very interesting video, but there's a bug : When you tell us about this spectacle in Budapest in which everybody applause at the same time, this is not a spontaneous fortuity happening . At the end of opera, theatre, classical concerts or spectacles, it is in use in Europe that when people loved the show, the clap their hands at the same frequency after the artists had salute their public to ask them to come back . If it's a concert, most of the times the musicians come back and sing another song . If it's an opera, the dancers and singers come back to salute their public once again . Sometimes the public do it again and again, and some times the artist accept to play this "game" . In French it's called: "un rappel", which means "a calling back" . Opera singers are proud to say that they had 2, 3 or more "rappels" because that means that specators really loved their performance very much . As you can see this synchronization is spontaneous, but it's a comon code that all spectators know, nothing to do with spontaneous fortuity . Thanks for this interesting video .

@Szabu This is actually quite a difficult question to answer. As someone who has many times as an audience member experienced that transition from applause to synchronized clapping I'm temped to say that yes it's an intentional thing that I choose to go along with once I hear it happening. But I've never really considered what causes the transition to happen. Like, who starts it?
Szabu 9 日 前
Waaaaaaaaaaaait a second. So do some people INTENTIONALLY synchronize the claps when this happens to signal a call back? I always assumed it's the same as for me. After a while clapping with enthusiasm, I get tired but it still feels impolite to stop, so I just go autopilot and make my motions in sync with sound, just like how people listening to music while walking tend to walk to the rhythm.

This demonstration of metronoms is a fail. Place the plate with metronoms on a few spheres and it woudn´t work. If you store the energy in one system, this will be the forcing power, not the little single ones. In this case it´s no syncronisation in between of the single systems. It´s triggered or forced by one power. Same timing is just a result.

This video was really neat, and got me to thinking about when I ran cross-country in high school. To move up in placement, I'd simply focus on a person ahead of me (but not the next closest/direct). My body would then naturally adjust my pace, to reach that individual, passing those between us, and I'd find I would naturally fall in behind them, my pace and steps syncing to theirs. Then, I'd repeat and focus on a new individual farther ahead, and the process would repeat as long as I had the endurance/stamina.
