How does order spontaneously arise out of chaos? This video is sponsored by Kiwico - go to 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

Humans. Don't get me started. As the herd of we primates fell into step, a perfectly reasonable way to move in a dense crowd -- Hello, army! -- they set up a dangerous resonance in the bridge structure, something the engineers had not anticipated. They should have studied human herds, amd the military, before drawing up the structure. During the American Civil War, and I imagine in all the wars of humanity whenever a pontoon bridge was laid over a body of water, the troops were instructed to break route step, and just shamble randomly over, like any crowd in a street. Resonance has long been noted for its destructive properties, (see earthquakes, wind and Galloping Gerty, the Tacoma Narrows Bridge failure) but I think, forgotten for its positive properties, both physical and mental. And for anyone who reads this and gets a redass about it, we are all primates, the alleged greatest of the great apes. Sometimes we act like that ... sometimes not so much. We contain both.

nature's Natural Feedback loop seems to propagate throughout our reality created over our natural humanistic existence expressed by some who have been acute to the feedback as a religious phenomena throughout the world. Our natural pendulum of life and death is especially perceived at death of a human system while during our life time some-we are sensitive to the humanistic experience as a whole called a civilization... realized as a moral pendulum written through out written history...

Explanation of why the one changes motion (after 5:44)is flawed.The arrows are drawn the wrong way. The TOTAL of the two that het in sync first will balance out with the counter motion of the platform, but that don't mean that the platform doesn't move. And the move of the platform is forced by the two that are synced already. Be cause of which it dominates the one that is still doing is own thing.

Synchronicity is interesting and there are more syncs... cause each spectrum(world) has an own much balance,as much the question is which balance we choose, which sync?Thatswhy parallel waves are important,we must choose our own balance then recognize the parallels and keeping the line...if we are in higher balance we learn but we get left behind or must try more times not to get left behind...if we are in lower balance we get not our results of our choosing which sync is parallel is very important...and not each sync is available everywhere...even in universe there are more balances...and there are more universes... basically we must find the parallel outside what we are already exactly inside... mostly people are choosing lower or upper nivou balance than themselves...but it's a good school in upper nivous to getting some knowledge or rolling in the deep to leaving the inner suffering behind...this channel has a good nivou.

hey man, i was thinking....if the synchronization works atleast with a solid connection(clocks kept on same surface or something like that) , wouldn't this solve the basic issue we had while we were trying to measure speed of light!!.....since the clocks were unable to synchronize then....we couldn't measure the speed of light in one way....but using these nomes....if we first set them up and let them synchronize over time (which they will eventually)....won't then will be able to measure speed of light in both(hence different) directions! possible or let me know please!
