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 discussion about the 2 clocks “synchronizing” 180 out of phase (3:00 thru 4:30) reminded me of something I witnessed a few years ago. Two of my grandsons (roughly aged 3 and 4 years old) somehow managed to wrestle two 6’ stepladders onto a trampoline. When I stumbled upon the scene they were both 1/2 way up their stepladders and bouncing on the trampoline 180 degrees out of phase (when one was highest in the air the other was lowest on the trampolines downward stretch). As dangerous as it appeared, it was at the same time fascinating. I can’t help but think that somehow they managed, without thinking about it, the same kind of synchronous movement achieved by the two pendulum clocks. I didn’t want to startle them and calmly asked them to stop. I was equally amazed when they managed to stop, climb off the ladders and make their way to the ground without falling. I was relieved and proud all at the same time. 😊🤷‍♂️ Now 17 and 18 years old, neither has any memory of it.

  • Those Kiwico kits sound great. I don't have kids buy like those kind of toys. A few years ago I gave a kit of a interlocking wood frame that made a dinosaur and it had an electric motor that gave it motion - The idea was he and his father would build the thing together. (it was age appropriate). One night dad starts t build it without him and completely messes it up - apparently he can't follow instructions. The moral is an interested parent is as much part of the equation as a cool toy.

  • Synchronized clapping in classical concerts is not an instance of the physical phenomenon, it is a matter of taste and expression of musical beings. It is voluntary, not emergent. It is rather likely to occur in concerts in Brazil and almost never happens in Poland. The person who put this in the video... has not been to many concerts. Clapping in phase means we want an encore. In Brazil and possibly elsewhere a pianist will give an encore immediately if the audience asks in this way. When I do want a bis, I listen to the clapping and find the pulse. It’s intentional.

  • The last comment about understanding. If understanding a way to get a grasp on things like disease and everything that is earthly would be a great first achievement. Then they can move on to the spiritual, worm holes and time travel. See all the parallel universes and dimensions. Everything seen and unseen is vibrating at an unknown resonant frequency. Our eyes can only see the light of this plane (earthly plane) that is vibrating. If only the eyes of our soul could see 👀 the spiritual plane, while still alive.

  • The law of entropy is not really about order in the sense of organisation and synchronicity. It's actually more about one very fundamental concept. For any process, the amount of energy available for work is diminished. As long as there is a difference of energy levels, there is a potential for a flow of energy and therefore a potential for work to be done. If all the energy in the universe was evenly distributed, things would be very orderly and synchronised, but the universe would be stone cold dead.

  • @Prof. Steven Strogatz and @Veritasium, I believe the reason why it is hard to figure out the properties of whole given the properties of parts is because, of the level of mental activity human mind can reach in normal state. Due to the limited amount of energy our body can process, it becomes very hard to understand the bigger picture, which is relative in different people's case.
