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

    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.

    The millennium bridge wasn't swaying because the people were walking in step, the people were walking in step in response to the lateral sway of the bridge. Their walking in step then caused it to sway ever more.

    @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.

    This can apply to all life, I’ll give you an example I was at a concert and somebody started a fight and somebody else in the crowd got angry and they started a fight, at the end of the concert it turned into a riot and everyone was starting to fight. This theory applies to everyone and that GOD is real, And synchronization is the key to the multi-verse.

    It was great to learn more about synchronization. It really helped me strengthening up my faith a little bit more. It reminded me of a God that puts order in chaos as Genesis 1-2 shows us. 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).

    Veritasium, can we please agree there is no experimental proof for entropy. If entropy is proven wrong over and over experimentally, if planets form from stars and organic life cycles thru life and death, exchanging disordered matter to then reorder. If we can consume elements like minerals and via enzymes convert them in to living cells then entropy is NOT REAL. Just the same as medicine, dogma exists. Entropy I hear over and over to explain time flowing in one direction... you don't need entropy!

    Reality is more fascinating than any theory. The magic attributed to the unanimated world is like a veil that prevents people to see its actual reality.And sometimes people becomes frustrated and even irritated when it is explained in simpler terms. The best example I know about it is when the great English poet Milton said Newton had removed the magic of the rainbow after Newton’s explanation of light.
