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/th...

    Back in high school we nearly tipped over a full-sized achool bus by everyone rocking from side to side in sync... and yes we got in HUGE trouble. We managed to get the wheels of the 10,000kg buses wheels to actually leave the ground on each rock, before the screaming driver made a hasty appearance; he was seriously freaked out.

    Every time I hear the, "synchronous" sounds I'm still heading 2 distinct, "clicks". I'd imagine I'd only hear one. I suspect people and bridges happen because of sway in their shared mounting locations and people do it because we tend towards cooperation.

    GREAT video! Really, one of the best I watched in the last months. However I am a young mathematician and I had knew to avoid frequencies rationally multiples of the resonant frequency of the bridge. They should have call a musician. However liked very much the conclusion too. Really, thank you.

    The words "disorder" and "chaos" when applied to physics/mathematics is often misunderstood. Something that appears like order to our human brain can and is perfectly in accordance with the second law of thermodynamics. And chaos is just a dynamical system.

    I feel like the same phenomena of synchronization discussed here is related to the same ability that birds and fish have to move together, all moving together, and change direction at same time and move as one body. Like how a school of fish will all off sudden all change direction at same time. Birds can do the same kind of thing flying in the migratory groups.
