How does order spontaneously arise out of chaos? This video is sponsored by Kiwico — go to https://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 https://www.quantamagazine.org/tag/th...

Whenever a lot of people are having a chat to the point where the room was so noisy and then suddenly everyone just stop talking to complete silence is someting that is mesmerising and scares me. It's like they/we unknowingly agree to stop talking at the same time

As a child I did observe that randomly people in group start walking in synchronization but could never reason it. This video was amazing tbh!

This would happen in my school where people would start banging on the lunch tables during lunch in the time of "We Will Rock You" and we would eventually get the entire lunchroom synchronized slamming on the tables doing "We Will Rock You". Good times.

Humans: well i guess we're going to make the most complex systems we can for everything!

I was a printer and operated a big flat bed machine which moved side to side. Notices were placed around the building saying "These machines must NOT be run in sequence. While bosses were out, apprentices deliberately ran three machines IN sequence. Milk bottles fell off tables and the building started to sway.

Synchronization even works with Walmart shoppers, when everyone ends up at the check-outs at the same time.

Those people walking on the bridge look exactly like a crowd walking off a cruise ship after a week at sea, people get used to the waves and walk opposite of them and the habit continues for a few minutes after getting off it's hilarious to see.

Remember when you were in the school lunch room and everyone happened to finish a sentence at the same time, causing a weird silence?

In a typical 20min Veritasium video, there is always a 2min period which put a smile on my face and tears in my eyes at the same time.

The heart spirals just make me think if Uzamaki now. I’m imagining the visual of someone tearing out their own heart with their bare hands just to get at the invisible spiral.
