The Secret of Synchronization

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

    As an entertainer, I've had audiences clap to request an encore, (just a few times - I was never famous) and it always starts out random, but the point at which the band must come back out on stage is when the clapping is synchronized, as if they were demanding another song. I always thought it was deliberate, but I sit corrected.

    This topic i like it the most..its about synchronization.. Good job Veritasium!!.. The way u try ur best to down on earth and let common people understand you is very appreciated!. Hugh applause!!!..and then now let us put this theory on human.. About the power of synchronization. The great synchronization in religious.😉. There are so many of religion, so many million of Gods and so more invented by mankind, and all of it just make it divide us more and more and became hostile and randomise in religious. Right?. That is the first rule of theory is unsynchonize and randomness . And now the second rule is to became synchronization and unrandomness, to came down and settlement.. what will happen is sooner or later humankind can't be helped but to synchronise to believe in one true God! U know why? Because within this theory all randomness unsynchronise of matter will come to one point the great synchonization..Right?. Do u see it?. U are very smart person. U should see it. Its ONE! No matter two object collide..they will became one as a pair..two pair collide it will became double cycle pair.. The number will grow. And they will always became one . This thing is happen because the single basic atom is from one neutron and one proton. From randomness of atomic world of proton/neutron either way they all will find their pair just to became one. They need to submit to the great attraction. And eventually they will decay but for the purpose to became one! Just like religion! Why people invented religious or Gods if there are non approval act of God? Unless their are. Right! The One God always exist. This great synchronization is a way to tell human its only One True God. U can find it with ur smart brain. The sign is very clear as bright of daylight! And its Islam is the approval way of life under His law. And sure did community of Islam will always appreciate the person so bright like. To unlock the secret of universe. And that was just only a drop of water in the vast ocean of knowledge of God Allah s.w.t itself! Dont be so late to get into sync bruh. And this might be ur call to join the pilgrimage. And i'm might be some random people write this..but i have my point. And this is holy month of Ramadhan in Islam. It's a great call to ur synchronization. Thats all, good luck..and keep always make us bright!

    This video reminds me of a doubt I have always had and never tried to research the answer: Might be possible for vocal chords to, inadvertently for us, synchronise the frequency at which they vibrate too? I mean, not in the way that a chorus harmonize their voices but, i.e several times when I'm talking to a person who has a very high pitched tone of voice and talks a lot, I ended up with throat pain like if I was the one talking too much and raising my tone, even if I barely talked myself. Does anyone else ever realized that?

    the audience does not clap synced spontaneously. in a concert you often change from normal faster clapping to slower louder clapping. After that transition of course it gets synct but not that magical. and regarding running: if your training partner runs really noisy on a loud surface it's hard not to adapt to his or her stride. both phenomenon are caused be most peoples need to go with the rhythm.

There’s a reason consciousness doesn’t make sense when it’s speculated upon from a perspective that omits the existence of God. We are who He made us and I am not you nor you me. I am who He says I am and science can only prove that. What power does the earth have above the Lord. Oh, how great He is that He should make this world and all of existence, which should strive for entropy, synchronize in ways specifically designed to support us. He didn’t make everything then decide to put us in it. He made all of existence just to have us and know us and that we may know Him!
