The Secret of Synchronization

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/the-joy-of-x

    Synchronized clapping in classical concerts is not an instance of the physical phenomenon, it is a matter of taste and expression of musical beings. It is voluntary, not emergent. It is rather likely to occur in concerts in Brazil and almost never happens in Poland. The person who put this in the video... has not been to many concerts. Clapping in phase means we want an encore. In Brazil and possibly elsewhere a pianist will give an encore immediately if the audience asks in this way. When I do want a bis, I listen to the clapping and find the pulse. It’s intentional.

    The last comment about understanding. If understanding a way to get a grasp on things like disease and everything that is earthly would be a great first achievement. Then they can move on to the spiritual, worm holes and time travel. See all the parallel universes and dimensions. Everything seen and unseen is vibrating at an unknown resonant frequency. Our eyes can only see the light of this plane (earthly plane) that is vibrating. If only the eyes of our soul could see 👀 the spiritual plane, while still alive.

    The law of entropy is not really about order in the sense of organisation and synchronicity. It's actually more about one very fundamental concept. For any process, the amount of energy available for work is diminished. As long as there is a difference of energy levels, there is a potential for a flow of energy and therefore a potential for work to be done. If all the energy in the universe was evenly distributed, things would be very orderly and synchronised, but the universe would be stone cold dead.

    @Prof. Steven Strogatz and @Veritasium, I believe the reason why it is hard to figure out the properties of whole given the properties of parts is because, of the level of mental activity human mind can reach in normal state. Due to the limited amount of energy our body can process, it becomes very hard to understand the bigger picture, which is relative in different people's case.

A God who holds all the wisdom and the secrets of cosmos (Job 38). A God who loves me and you with sacrificial love (John 3:16) and who will eventually put everything in place again (Revelation 22)

    Two pedantic notes from a retired electrical engineer: [1] The bridge sync is like any system that has a resonance (and there may be more than one resonant frequency in a system). Electrical engineers routines apply "white noise" (randomness) to a resonant system to determine its resonant frequency(s). [2] When two timing sources are "close" in frequency, then something called a "beat" frequency results from the difference between the two frequencies. For example, if one is 0.1% different from the other (i.e. "close"), then there should be one "beat" every 1000 cycles. If 0.01% apart, then 10000, etc. Now if that frequency is from something slow, like a metronome or pendulum, say 1/sec, then you would have to wait 10000 sec (about 2.8 hours) before they sync, but only "momentarily", before they start to drift away. Then there's the "anti-beat" when they're motions are synced oppositely, at half the time, but repeats at the same frequency of once/2.8 hr. Now that also assumes that these are perfect timing systems with no animalities to throw a stick into the spokes, otherwise, more chaos ensues. Now multiply that to say 50 metronomes. The math gets more sticky, like the complexities of the 2-body vs. 3-body (or more) celestial orbital equations. But then computers were made to simulate is stuff so we humans can stay (mostly) sane. And this shouldn't detract from any enjoyment of the simplicity of the world around us, just know that it's there and the engineers (mostly) know how to address any issues that come along (albeit, after the fact sometimes).
