1. I am so blown away by this. You are a treasure! And so are Poincare, Lorenz and Mercury!

2. What I adore about this video and Sabine besides the fact that its a well made video about one of my favourite topics in my field is that Sabine is probably going to be so confused as all of the references to Sonic/Shadow the Hedgehog lol.

3. shadow has entered the chat

4. biological chaos: the heart beat. question: why is chaos control not required for a healthy heart beat?

5. Wish we could get some COVID chaos control

6. Fantastic video! Congratulations and thank you

7. Obligatory warhammer reference:
   BLOOD FOR THE BLOOD GOD!!! SKULLS FOR THE SKULL THRONE!!!

8. Tokamak ?How about the helion?

9. What if it's not chaos it's planned by a higher force. Literally everything we react to is in the past, so wouldn't it already be controlled?

10. I would like a video explaining why Earth is orbiting the instantaneous position of the centre of gravity of the solar system Vs aberration (especially with respect to motion around the Milky Way) Vs system stability. There is something there I don’t really get wrt to causality.

11. Maxwell Smart was able to control KAOS!!

12. Can you truly control chaos or just kick it down the road of fortune 🥠 👁️🔮???
    At all levels 🧬 ⚕️☯️ confucianist balance ⚖️, attempting to obfuscate cascade failure & deny the reality of decay & entropy 😂🤣😭 of intrinsic infinitely complicated systems in lockstep with each other???

    Chaos theory now Con-theory 🤔🧐 🍫🫖🕛🙃🫠

13. "Chaos Control" sounds like the name of some supervillain's organization for world domination. and the fact that they're talking about controlling the weather isn't helping.

14. AI + robots + fusion energy = a world of abundance for humanity

15. Thanks for the excellent summary update on Chaos.

16. I love Germany and very intelligent Sabine Hossenfelder☺👍..Watch your step with evil Russia, China and evil North Korea including evil dizzy Trump.

17. Great video. Small correction: Boston Dynamics Humanoid Robots don't use AI for the walk control . They use a technique called MPC (Model Predictive Control). They are working on reinforcement learning techniques but it is still not ready. In fact, Humanoids are still not good at walking and they still fall. It is pretty much the same techniques as 10 years ago. The reason why BD Humanoids walk well are the hydraulic actuators and the well mastered MPC.

18. TO STOP CHAOS ALL YOU NEED IS TO CHANGE THE NAME TO SLAVERY THEN ADD A PINCH OF STEALTH GOVERNMENT AND A LITTLE RELIGION AND ADD IN CAPITAL PUNISHMENT TO THE SIN LAWS AND WAAA LAAAA "TOTAL CONTROL"!!!

19. Is this title meant to be clickbait or didn't she know about Shadow?

20. Welcome to complex systems

21. Is the law of large number a manifestation of entropy?

22. These developments show me one thing: Countries, ideally the whole planet though, should put the discussion about computer controlled, fair command economies and resource allocation back on the table.

    Pronto. It's time.

23. This was fantastic.

24. Caius Ballad: "I told you so."

25. I remember reading a book about chaos theory when I was a young man. What fascinated me is how chaos theory actually make sense in producing diversity in the Universe. They say mutation in living being happens randomly, That randomness is due to chaos in any dynamic system. What I just learned through your video about chaos control confirms that it is how evolution works. A little randomness, then the pressure of the environment selects only the genes that are back in order in a way. I may be extrapolating a bit, but I believe it is not far from the truth. At least one thing is certain, it needs a little bit of chaos to create new shapes in the Universe.

26. Humble intelligence is the sexiest thing ever.

27. Thanks a lot for this very easy to understand introduction to chaos control. Most of the examples are excellent. However, I am surprised that you are using robots as a meaningful example of control of chaotic systems. Even though robots are chaotic systems, they can be designed in such a way that controlling them is easy. Ideally, a robot would be designed as a differentially flat system (the output of the system is an algebraic expression of a finite number of derivatives of the input) which makes it easy to control both in open loop for motion planning and in closed loop for operational adjustments.

28. War flashbacks to the 2005 Shadow the Hedgehog game.

29. I can't blow Sabine a kiss because I don
    t know if it will result in a storm …

30. From a layman. Isn't chaos in the AI as well?

31. I used to be a roboticist at Boston Dynamics and am now working on plasma control for fusion reactors. It feels cool to see a video that feels so personalized 😛

    I just want to point out that "chaos control" isn't a standard concept. People usually just talk about "control theory" because, well… pretty much every real world system is chaotic once you take into account all the disturbances and subtleties. It's a pretty cool subject, and I highly recommend Steve Brunton's videos on it.

    There has been a pretty big convergence between the fields of artificial intelligence and control theory in the past decade or two. In fact, it's been known for several decades now on a theoretical level that the fundamental problems of "optimal control theory" and "reinforcement learning" are more or less the same thing. In both cases, we're just trying to solve a computational problem to find the actions that achieve the goals we humans set for the machine. Cross pollination and synergy of ideas between the two fields has indeed been fruitful, but I do think machine learning has gotten more credit than it's due in this area (there are some serious challenges to basing control of real systems mainly on machine learning). If you watch the hour Boston Dynamics talk on how Atlas (the humanoid robot) does it's thing, you'll see that the advances there probably have even more to do with advances in computing power and real-time optimization than anything else: https://www.youtube.com/watch?v=EGABAx52GKI&t=4176s

32. where does the use of chaos emeralds and hedgehogs come into this?

33. With help from AI, this becomes an engineering problem

34. I wholeheartedly agree that it is easier to just let me throw the spaghetti at the wall…

35. The world is not orderly. It is extremely chaotic. Order is just a myth created by society, which is extremely fragile and hostile towards differences and deviations from it.

36. Let's be honest…

    We were all thinking Sonic the Hedgehog

37. I love Sabine!

38. Oh no, Shadow is at it again!

39. Did Shadow the Hedgehog post this?

40. going to have to watch this one again. once again so grateful to have found this Channel thank you Sabine.

41. I love her videos , even when I don't really understand it . Fascinating !

42. Isn't the term, "chaos control" an oxymoron? Or at best, definitions describing approximations? Something is either chaotic or, something else.
