    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

      "The bridge had undergone a phase transition" ... How do I get excited about this sentence? 😂

      Really Great video. Would you do us a favor and talk about the safety of the radioactive water Japan is planning to dump into the ocean? Really really concerned

      “The whole is more than the sum of the parts” -19:19ish. I like to hear this. I believe we have souls and individuality. There’s a reason consciousness doesn’t make sense when it’s speculated upon from a perspective that omits the existence of God. We are who He made us and I am not you nor you me. I am who He says I am and science can only prove that. What power does the earth have above the Lord. Oh, how great He is that He should make this world and all of existence, which should strive for entropy, synchronize in ways specifically designed to support us. He didn’t make everything then decide to put us in it. He made all of existence just to have us and know us and that we may know Him!

    5. Bird Box

      its simple!

    6. Mr. Logician

      Matter can behave like this, but mind has different mechanisms, it can still swim accross the stream, even when whole world seems to be against one mind, mind can still keep moving in the direction of its will

    7. Nosho

      Gaining a better understanding of the wide range of effects of feedback loops and emergent behaviour is the next big leap for most sciences.

    8. Berika Beridze

      Very interesting video, thanks! And what about the synchronization in living organisms? For example, in Humans dance synchronization. Or is there any other exaples? Maybe in Birds on other mammals? Or even unicellular organisms 🤔

    12. Briz KT

      A thought that occurred to me is where, if applicable at all, does the harmonic series (Sigma 1/n to infinity) come in? Nearly all, if not all, naturally occurring synchronizations can be mathematically represented via the harmonic series, from music, rotating bodies, and wave dynamics.

      What if you put them perpendicular to eachother? Like, the object itself perpendicular to eachother on top of the platform.

      This video does nothing to explain this phenomenon.

      Hi, is there a way I can send you an email about something i discovered from your previous video? I can't really stop thinking about it and I hope I can share it with you because I know how good you are at explaining things. It's all about space-time. And I think i have an idea that we never thought before.

      When we don’t understand the synchronization, we call it chaos.

    29. bhasky

      Absolutely cracking video. I always had this question , when I read 2nd law of thermodynamics. Entropy always grows. Then there must be a fight between system getting destroyed over time and system maintaining itself .

    30. Andrew Pascal

      Prof. Steven Strogatz was absolutely amazing to listen to! I'm definitely grabbing a copy of his book.

      We can't use psychologically/ biologically synchronizations of people and bugs as an analogy to physics.

      Hi I have a question. Why when we want to spin a can with liquid inside in the air it stops by itself?

    39. Глеб Жеглов

    40. Lorenzo Bianchi

      This phenomenon can be used in analog synthesizers, or in digital imitations of the principle, to obtain the syncronized sound of different waveform, which give different results depending on the waveshape, the oscillation period, the phase and other parameters. It's amazing how things apparently so different can follow similar, simple rules.

      Another example: In Football stadium, one fan begins a chant, then another joins, then another, then the whole crowd's singing. Same with the Mexican wave.

      Energy creates energy? Objects in motion stays in motion. But law of energy states, it cannot be created or destroyed.

      I see my city, I upvote.

    52. Alexton rahdeeo

      10:00 i don’t think this is a sync ... it’s just something that is done after every show to call actors back on the scene .... Literally every I’ve been to or saw

      The clip where the audience was clapping and then when they all clapped in sync freaked me out. How beautiful nature is, man

    57. morbikdon

      mannnn hell of a video!

    58. Mister Murtad

      What if you started the metronomes on separate tables. Would they still pick up the syncho from the floor?

    59. LoudSilence

      If all humans sync their steps maybe we can push the Earth out of the Solar system.

      air is the coupling between fireflies. The Vibration of the Coupling is what determines the speed at which actions Synchronize. Increase or decrease the Vibration of the Coupling or Medium and you will see the speed of Synchronization occur faster or slower. You can control this.

      regarding the frequency of steps to make a bridge move. it's not only half and double the frequency, it's also the thirds. in other words 2=3 and viceversa, same what happens in triplets in music. 75 b.p.m = 100 bpm (3=2) and also the other fractions same as the nodes for harmonics in guitar string.

    83. Michael D

      Any suggestions on where to find methods for determining/calculating the resonant frequency of a structure like a bridge? I'm not looking to learn all of civil engineering, but rather a short instructive video?

    84. Steven Verrall

      This is why the Universe is not governed by the laws of thermodynamics. As such, theories such as the Big Bang, Dark Energy, and Dark Matter are based on a foundation of flawed assumptions. The Universe is actually governed by plasma dynamics. Plasma researchers have long observed self-organizing systems. The Universe may actually have become more ordered with time. There may actually be a natural balance between plasma dynamics and thermodynamics where increasing order in one place is balanced by increasing disorder in another. In this sense, our Universe may be an eternal system. If humanity believes the Universe is an eternal system, we will finally be able to give up our harmful obsession with fatalism.

    85. Richard Levy

      Excellent video. I suspect predicting the behavior of individuals in response to economic factores might take a step forward using the principles illustrated in this video.

    86. Jehu McSpooran

      The funny thing with the clapping is that quite often the entertainer will get the audience to start clapping in time. Once the sync has started, the speed of the claps increases as the fervour grows until spontaneously the sync disappears and random clapping takes over. I've never seen it go from chaotic to synchronous.
