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

  • What you call "chaos" is in your mind. Your mind understands by chaos, an order that canot bne fully understood due its complexity, and that's called epystemologycal randomness. Chaos is for you the opposiet to order and perfection; but your idea of order and perfection are not based on what you wish would be order and perfection. The order and perfection you talk about is a frozen lake; and trhat you call chaos is Harmony; dynamic order, etc.

  • Question is, mostly to get something synchronised we need to wait until it get synchronised. Can we limit the required time of the synchronisation? I am sure if we can do it so this might open a new possibilities to treat cancer as we can get the uncontrolled cell division and metastasis in a synchronisation.

I saw in the notification bar that when on sign was fully highlighted the other was half but after some time both were in sync(both were highlighted by same amount.

  • Here are 12 important questions and answers before considering getting vaccinated: ?"If I get vaccinated can I stop wearing a mask(s)?" Government: "NO" ?"If I get vaccinated will the restaurants, bars, schools, fitness clubs, hair salons, etc. reopen and will people be able to get back to work like normal? Government: "NO" ?"If I get vaccinated will I be resistant to Covid?" Government: "Maybe. We don't know exactly, but probably not." ?"If I get vaccinated, at least I won't be contagious to others - right?" Government: "NO. the vaccine doesn’t stop transmission." ?"If I get vaccinated, how long will the vaccine last?" Government: "No one knows. All Covid "vaccines" are still in the experimental stage." ? "If I get vaccinated, can I stop social distancing?" Government: "NO" ? "If my parents, grandparents and myself all get vaccinated can we hug each other again?" Government: "NO" ? "So what's the benefit of getting vaccinated?" Government: "Hoping that the virus won't kill you." ?"Are you sure the vaccine won't injure or kill me?" Government: "NO" ?"If statistically the virus won't kill me (99.7% survival rate), why should I get vaccinated?" Government: "To protect others." ?"So if I get vaccinated, I can protect 100% of people I come in contact with?" Government: "NO" ? "If I experience a severe adverse reaction, long term effects (still unknown) or die from the vaccine will I (or my family) be compensated from the vaccine manufacturer or the Government?" Government: "NO - the government and vaccine manufacturers have 100% zero liability regarding this experimental drug" So to summarize, the Covid19 "vaccine"... Does not provide immunity Does not eliminate the virus Does not prevent death Does not guarantee you won’t get it Does not stop you from passing it on to others Does not eliminate the need for travel bans Does not eliminate the need for business closures Does not eliminate the need for lockdowns Does not eliminate the need for masking If after reading this you still decide to get the "vaccine".. This was taken down from my FB page within 10 seconds of posting. Let's seehow the YT algorithmn views it.

  • As Spock would say, FASCINATING CAPTAIN. I’m an electrical engineer who was trained in many topics discussed here. I understand resonant frequencies. We had a photo in a hallway at college (Drexel U.) showing Galloping Girdie, the famous bridge that self destructed when the wind blew just hard and fast enough to make the whole bridge swing like a huge sine wave. The message was clear to us engineering students- don’t allow this to happen! I really liked the end where the guy said his career was not breaking a big problem into smaller pieces, but combining small pieces into a big picture.

  • Im no scientists, and this is just my brain going off on a tangent, but.... To understand the complex whole, perhaps instead of putting it back together in its entirety, we should see how it interacts in parts. As said, to understand how X works, science breaks it into smaller parts, for example: A B C and D. Then we figure out how these work by themselves. Now lets assume we figured out how these work on their own, but when we put them back together the result baffles us still, would not the logical next step be to first see how these singulair parts interact with eacother individually? How do A and B interact. How do A and C interact. A and D. B and C. And so on and so forth. Once we know how A and B interact, we introduce C into the mix, and see how A, B and C interact together, and wether or not this somehow influences or even changes the function of A, B or both or all. Once we understand all the various different interactions, perhaps the whole will finally make sense.

  • 4:40 The LEM I passed up because I want the rocket :) Also this whole video is a demonstration of why you just can't predict the properties of the whole from the sum of the parts unless you can harness chaos. Yes it would have been easy to test the bridge before hand, just as with Tacoma Narrows, but who would ever think a massive structure of steel and concrete weighing millions of tons could whip around like a flimsy silk ribbon? The very nature of chaos is its unpredictability; by far the best example I can think of is people. You can put two ice skaters on the ice and they can jump around in sync, but when they interact with each other they can do many things neither could do alone; and what they can do is chaos; there is no way it could possibly be predicted
