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 www.quantamagazine.org/tag/th...

The entropy thing has always messed with my head. Living beings are so wonderfully complicated and an organized wonder. If things move towards disorder is that proof of intelligent design? Just another example of coincidence? Not a smart man by any means so it's probably just a lack of information.

[@sciencedavedunning3415]

@easley421 The Egyptian concept of the "Ahnk" , and the Greek version, "Cosmos" each refer to the tendency of matter toward higher levels of organization. The "life" force. "Entropy" is the opposite, ............ death, decay....... the tendency of matter to fall into disorder. You cannot have one without the other. The universe must maintain it's natural balance. Imbalance is chaos, confusion. I hope this helps to clear up some of your confusion. 🙂

But physics isn't all around us. Physics is the product of the human mind.

I went to a recording for a German TV show yesterday and I really enjoyed the sensation of when we, the audience, were clapping. We were in a circus and arranged around one circle in the middle, so I could look at people face to face, to the other side of the middle. (the show is called "Stars in der Manege" in case any German speaking person reading this wants to see it) When music was playing we started clapping in sync, a room of over a thousand people syncronized without any instruction to do so. It happened at different paces each time, some times the irregular phase lasted longer and others we almost syncronized right away. When we were in sync I loved looking around at a random person and no matter where my gaze went, I was in perfect sync with that person. funny how this video showed up on my feed one day later

[@klauskinski4060]

Synchronicity!!!

[@emmetthowell899]

I just realized I’ve experienced synchronization with clapping. My high school did a thing at lunch where one table would start randomly clapping and others would join in until the entire lunch room was clapping. One time it got a lot louder suddenly and I figured it was just my weird hearing but I think it was synchronicity especially because we had strong coupling. My school had a bunch of groups strongly opposing each other (mostly divided by political views) but one thing that could bring all the people together was the clapping, even the most reserved groups would get in on it. Some teachers hated it cause the noise and others liked it because it was nice seeing all the students doing something collaboratively

[@WigglyStuf]

That’s a cool story

[@mnotchchuang9663]

this reminds me of a phenomenon that sometimes a noisy class would simultaneously stop talking. In the short sudden silence everyone is like 'WTF', and finds out that it was a false alarm-the teacher hasn't come yet, and continues chattering.

[@laserapfel24]

I would assume that people synchronized their frequency in which they talked so everyone stopped at the same time and was wondering if everyone else was quiet because the teacher arrived so stopped talking as well. But could also be just random and not related to this at all I guess

[@jasoncrocker881]

You're forgetting about the one kid that says a curse word super loud whenever this happens.

Or when class is about to end and with seemingly no trigger (bell, timer going off, teacher dismisses class) people just simultaneously pack up and leave. It's interesting being in the class when that happens because you're like "how do I even know to do this" then the bell rings.

[@andrasfeszthammer9800]

In Hungary, members of the audience purposely sync up the clapping to honor a great performance. We call it the "iron clap". After a while, it disintegrates into just random normal applause, but people will again try to sync up. It's fun and the performers love it.

[@tim40gabby25]

.. yes - the clap speeds up, as folk hear an early clap but not a late one, till it's too fast to maintain. The Icelandic slow shout is extraordinary different, as it's not cool to be the first to shout, so it slows down, if anything. Other countries cannot reproduce it as they do not obey that single social rule. Love it :)

i don't want to bring any unwanted controversial topics into discussion, nor do i want to do any sort of weird theoretical 'hand waving' of natural phenomena- but what do you, personally think of Theism in the context of being a theoretical possibility? now when i refer to 'Theism' i don't mean any specific belief system or any specific religion or any of that, i mean do you think it is possible that there's _something_ responsible for everything? i genuinely want to beg that question, not from any desire to 'convert' you into believing something- i ask purely from a place of curiosity. i haven't personally seen any genuine scientific debate regarding Theism, and i think some actually very interesting discussion could come from it if people would set aside personal flag-waving momentarily. i would only want to engage in such a discussion with anyone if they were comfortable in doing so, however.

[@greenmanofkent]

From what I have seen, synchronized clapping doesn't just happen - there is a purpose behind it. With synchronized clapping, the audience is asking for an encore or curtain call by the performers, and it only takes a few people to start it. Interestingly, the beat in synchronized clapping is almost always considerably slower than regular applause - I wonder what the explanation for that might be.

[@jinxedsphinx3600]

Really? Weird because it kind of creeped me out for some reason...

[@OurLadyOfSorrows4]

Yeah it's not completely a coincidence. Once you hear people clapping in unison, which means they really liked the show, you either join in to signal you also enjoyed it, or you stop clapping if you didn't like it that much.

[@doeb23]

As a Hungarian I only have one comment: the synchronized clapping is called "Vastaps" ("iron clap") and is a traditional way in Hungary to express deep admiration and appreciation for the performance on stage. As it is tradition and everyone knows it, the synchronization is not completely spontaneous - we expect it, and as soon as we hear a tiny pattern, we intentionally join in.

[@jro92782]

And I think that is his point exactly... as soon as the pattern gets recognized, everyone follows!

[@christophersanders3252]

Ever since I was a child, I've noticed that when people walk together, they end up walking with synchronized steps. I thought it was some kind of telepathy or, at least, a no-verbal communication. I never realized it is actually a phenomenon in physics and chemistry.

[@leighatkins22]

It kind of is a type of "telepathy", just not what most would recognise as "telepathy"... I believe that data like this is often transferred thru our electromagnetic fields as well... u could blindfold all these ppl and make them walk across the bridge and as long as they don't bang into each other, they will still end up doing the same thing. We can't help what we are...

[@oscargardiner3168]

[@miagi1337]

When you have the same height and you walk the same speed you already have the same step frequency. And don't forget that you hear the other ones steps even if it is pretty subliminal. Also when you make steps your body moves up and down a bit, that you can see. And while the brain kinda stabilizes the picture of the world, another person moving up and down out of sync is noticeable. So that are already two channels of information if you pay any attention to the other person and it's not too loud.

As a Hungarian I never tought that some people didn't clap like that, but its apparently a mostly eastern european thing. I always tought of it as a milder form of a standing ovation. And I think its absolutely not as spontaneous as people think, people might do it somewhat subconsciously, but only because its culturally ingrained, everyone did it that way since they were a kid, so they follow along. Like I never suddenly realized "wow we are clapping in sync randomly" more like "ok everyone liked the performance, I guess we are doing the syncing thing". There is always some guy that starts it by clapping slower and louder, then everyone follows, we speed up until its random again, repeat until we are bored.

This is a really interesting (to me) observation. In 50-some-odd years of participating in applauding audiences in the US, I've never experienced full synchronization, just near-miss synchronization.

I always wondered why audiences would start clapping together. I always figured it was the concerted effort of a group of people and people start copying to make a more deliberate clap, that I would consider to be a more enthusiastic clap for a great show. But maybe it only happens for great shows because people are clapping longer and therefore giving themselves time to synchronize? Interesting. I was always the weird kid paying attention to clapping when I was a kid. In church people often clap in sync with the music, and when I would try to clap out of sync, it was very difficult and I would keep trending towards synchronization, even though I was consciously objecting to it. This explains a lot! But I feel like it could be explored more deeply in relation to how this not only affects human psychology, but the effect of their behavior, such as analyzing economic market behavior.
