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

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.

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.

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.

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.

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.

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.
