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

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!

"It was only a few decades ago that scientists started fleshing out a rigorous theory of synchronization." I don't believe that because it seems too easy. Framework of proof (for pendulums on a common movable platform, but this can easily be generalized): (1) Assuming there were 1 pendulum only, express the effect of the movement of the 1 pendulum on the movement of the platform. (2) Express effect of the movement of n asynchronous pendulums on the movement of the platform. (3) Express the effect of the movement of the platform on the movement of a pendulum. (4) From 2 and 3, generate a system of equations for the cases with 1 and 2 pendulums. (5) Solve for the equilibrium in a case with 1 and 2 pendulums, with arbitrary starting values. (6) Show that the equilibrium does not change if you add 1 pendulum, regardless of the current number of pendulums. Alternate proof framework: (1) Prove that regardless of current state after one period an apparatus with 2 pendulums is closer to synchronous equilibrium by more than some fraction of the present distance to the synchronous equilibrium. (2) Prove that for an arbitrary number of pendulums by induction. (3) Prove that the sequence of distance to synchronous equilibrium indexed by period asymptotes to the 0.
