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

    the synchornised clap in audience is (most time, or always) on purpose, audience voluntarly recognizes when certain volume of the claps becomes (even a bit) synchronized, so they all "tune in". I've been many times part of it, well, I grew up with it. It comes at the end of the concert and it just feels nicer (when aplause last quite a while) to be synchronized than to be random noise. It is sort of message " we all agree this was truly great, so we aplaud to you in sync"

    I've always thought this was the explanation for Carl Jung's Synchronicities, the 'Acausal connecting phenomenon'. Self fulfilling prophecies and psychomotor effects show how the mind can bleed into physical reality. On larger scales perhaps even spookier 'coincidences' can occur. I don't want people to think that 'Magic is real' by any means. But perhaps its just the tiniest bit realer than we think.

    Back in the 80s, My friends and I went to a concert at a very old venue in Boston, MA called the Orpheum. We were in the balcony, and it was sold out and very crowded. As Depeche Mode played their electronic music and people were bouncing in the balcony, the balcony started to shake, and as the bouncing and dancing continued, the structure became more violent. It wasnt until Orpheum officials came onto the balcony and tried to persuade us to stop dancing, did it stop. I was panicking and honestly thought the whole thing was going to collapse... Being high on pot at the time seemed to amplify my anxiety.
