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

  • What do you say when you're only one of millions of viewers, and also only one of thousands of commentators? I say that this highly informative, and extremely amusing video is one of the best I've watched for a very long while. If we can lean something new each time we live a new experience, then life is worth living. A man lifespan only allows us to scratch the surface. Thank you for sharing this.

  • Back in the 80s, My friends and I went to a concert at a very old venue in Boston, MA called the Orpheum. We were in the balcony, and it was sold out and very crowded. As Depeche Mode played their electronic music and people were bouncing in the balcony, the balcony started to shake, and as the bouncing and dancing continued, the structure became more violent. It wasnt until Orpheum officials came onto the balcony and tried to persuade us to stop dancing, did it stop. I was panicking and honestly thought the whole thing was going to collapse... Being high on pot at the time seemed to amplify my anxiety.

  • I believe that the synchoniity the metaphysical phenomenon has explained by C,G. Jung is a similar physical effect has this snchronization of pendulum on the same platform and that althought experienced subjectively as meaningful it is something objectively physical on a level of harmonization we do not perceive easily as it implies to many elements acting simulteneously to create our objective reality. That would be no surpise has we have disovered that on the level of the atom reality is much more pliable then on the molecule level. So in the phenomnon of jungien synchronicity it is not so much the subject creating reality then a series of entanglments producing a synchronized reality that al a sudden becomes meaningful in a subjective way for the experiencer as after all we are not seperated of reality and that we are all linked in a way in what happens in what is invisible to our 5 senses. most probably all this will be proven when we understand better our physical reality with improved tools and theories.

  • The universe is a perfect system, there's no way disorder is the normality. Sure, it starts as it, kind of, but it's all designed to go towards order and evolve towards order and even avoid disorder to happen back again (reason why detected things look ugly and undesiderable). Everything that evolved becomes ordered.

  • We've seen this same (destructive) self-synchronizing behavior in network protocols. And this applies over many orders of magnitude of time/frequency. Back when Ethernet was half-duplex and relied in collision detection and back-off for retransmission, the spec says you need to do exponentially increasing back-off.. but with a randomized component since other stations in the same ethernet collision domain were also doing the same thing. You didn't want to have perfectly synchronized retransmissions by all the stations waiting just dozens of microseconds later. Same applies to routing protocols that send updates on the order of tens of seconds; many of these have flooding behavior, but you want to add a randomized component to the timers to avoid synchronized updates. It's a common practice these days, though something to behold back when that was learned the hard way. Thanks for the interesting video! It's really quite amazing how some principles like this span so many disciplines.
