Special thanks to Prof. Mason Porter at UCLA who I interviewed for this video.
I have long wanted to make a video about chaos, ever since reading James Gleick's fantastic book, Chaos. I hope this video gives an idea of phase space - a picture of dynamical systems in which each point completely represents the state of the system. For a pendulum, phase space is only 2-dimensional and you can get orbits (in the case of an undamped pendulum) or an inward spiral (in the case of a pendulum with friction). For the Lorenz equations we need three dimensions to show the phase space. The attractor you find for these equations is said to be strange and chaotic because there is no loop, only infinite curves that never intersect. This explains why the motion is so unpredictable - two different initial conditions that are very close together can end up arbitrarily far apart.

This just asserts that we, and all the machines we can develop, are too limited to read the future in the present, while Laplace's demon still could. (Why is it called a demon?) I wish Mr. Veritas hadn't dismissed the uncertainty principle so easily, bc if the tiniest aberrations have huge effects in the long run, atomic level should have at least some effect… which will, of course accumulate over time. And thus, determinism crumbles. Right?

As a linguist, I have to clarify: that's not a "true" paradox, but rather an "apparent" paradox; it's not that the initial conditions of a system can never be known, it's just that they can never be known by US. If you had a theoretically omniscient being--true omniscience--the universe would be completely deterministic from that perspective.

I think the past present and future all exist at once, but is not written in stone. The decisions we make on a daily basis are translated through space and time where as the time-lines are constantly changing and those ripples travel instantaneously through it. Spooky Action At A Distance is where what you do to one atom here the other far off in another distant area of space is affected immediately.

In his book Cosmic Blueprint, Paul Davies gives a most simple example of a chaotic system which I found very illuminating: take a binary number between 0 and 1 and multiply it by 2 (shift all bits one to the left). If the number becomes larger than 1, subtract 1 (remove the 1). Subtracting the 1 like this is the non-linear or chaotic part. For example: 0.1001001000011 times 2 becomes 1.001001000011 and removing the 1 becomes 0.001001000011. If you study this operation you can easily see that if you start with two binary numbers which are the same up until the nth bit they behave similar up until the point where they have a bit that differs. If for example you have 0.01011001010001001 and 0.01011001011001001. After 9 times the performing the described operation the first number becomes 0.10001001 and the second 0.11001001 which is not yet much of a difference but then, after 10 times the numbers become 0.0001001 and 0.1001001 and they really start to diverge. Now it can be easily seen that to predict the future of a point for twice the more steps, one needs twice the more digits behind the comma. This is exponential so predicting becomes very hard (in practice impossible due to limited measurement accuracy) very fast (Davies states that for non-chaotic systems, you normally can predict twice as far into the future by adding one digit which is a far less requirement).

Initial conditions are important in a controlled environment, but if someone or something attempted to purposely stop or sabotage the experiment, those factors outweigh whatever the initial conditions might have been.

How do we know that these plots look the way the actually do? What I mean is that I assume these plots are generated through computer simulation, which requires us to select an initial starting value. Since the system is so chaotic, these initial values are very important. Since computers are only able to represent numbers with finite precision, that means all the initial conditions we choose will be rational numbers (is that correct?), which is a meager set of all real numbers. For example, how do we know that initial condition with transcendental numbers will not produce a completely different looking plot?

Fun fact: when the media says the world will be destroyed by climate change and it's due to co2 it's not grounded in science because even the scientists cannot predict how climate will change, let alone corporations whose main goal is scaring you into submission. We don't understand the earth enough yet to predict what it will do (of course keep plastic out of the ocean and whatnot but don't think you're saving the planet by riding a bike instead of a car, although you probably should do that anyways because health)

Movement of the hand effect: It's the last hour in school, the bell is just about to ring. You want to put all your stuff in bag and go, but then you move your hand a bit and a pencil falls on the floor. It takes you about 3-5 seconds to grab the pencil, but in this time more students went out of all the classrooms on the corridor. People are walking slowly and so must you. In the end you waist so much time that you miss the bus. And you missed the bus just because you moved your hand a bit too much. Now you'll have to wait for another one. It changes quite a lot. If you wouldn't move the hand, pencil wouldn't fall, you would come in the corridor faster, there would be less people so you could run faster and you would come on the bus station just in time. Et voila

I don't know if this totally counters Laplace's Demon. Part of the assumption is that the demon has the collective knowledge of the current state of all particles and can thus predict the immediate future. If we extend it further to say the demon has knowledge of all states that every particle has ever had, then it can predict the future with total accuracy. Chaos is more or less removed if the starting conditions are a perfectly fixed state in space, time, etc.

That part was poorly written. While the exact position of planets on their orbits is chaotic over tens of millions of years, the shape of the orbits themselves is far less chaotic and predictable over billions of years. The Earth isn't flying away ever, let alone anytime soon.

I tested positive to genital herpes virus (HSV 2) in 2002. I was having bad outbreaks. EXTREMELY PAINFUL. I have tried different kinds of drugs and treatment by the medical doctors all to no avail. Three months ago I was desperately searching for some helpful remedies for genital herpes (HSV 2) cure, when I came across some helpful remedies on how Dr. Bali have helped so many people in curing genital herpes (HSV 2) with some herbal treatment, I believe too that there is someone somewhere in the world who can cure herpes completely. In the past 2 months, however, I've been following his herpes protocol Via (drbalihome@gmail.com) or WhatsApp: +2348120933032 and it stopped all outbreaks completely! To my greatest surprise I was cured completely by following the protocol of his herbal medicines. Don't be discouraged by the medical doctors. There is a cure for HSV with the help of herbs and roots by a herbal specialist called Dr Sani, he is so kind and truthful with his herbal treatments. Kindly contact him for more information Via Email: drbalihome@gmail.com or WhatsApp on: +2348120933032 You might be lucky as I am today..

A professor of mine from Stanford explained to me once the unpredictability of weather with an analogy of throwing a tennis ball in a closed room from a starting point, X, and let it bounce a million (or more) times. What is the end postion after t time? Now re-do the experiment but change the starting position of the tennis ball with the slightest displacement in starting position, X+delta X where delta X is very small. Where will the tennis ball end up after t time? At a completely different position.

God is real and it's obvious. Look how perfectly balanced our universe is that we even exist. Everything from the shape of our earth, to the ozone, to the rotation. Ifbit was by chance then we could simply put a bolt and a nut in a box and shake it for billions of years in hopes that it will eventually screw itself. Even if you hate God, or you won't read the bible because it was written by man, you are putting your faith in something each day. God is bigger than your emotions and your intellect. As a Christian, I believe in the big bang theory. It matches to to Genesis.

Does it not scare anyone else that if we could calculate every piece of matters speed and mass that we would know the entire future, there’s not doubt in my mind that that is true, and if it really is true then future is already determined and what ever you do you were always going to do it, so how much choice do we really have because we were going to make any choice we make anyway, everything you do, everyone you see all this was going to happen exactly how it happened and will happen and there’s no control you really have. And just because we technically couldn’t calculate it due to the butter fly affect that doesn’t mean it isn’t real, and what scares me most is it’s not really just a theory, it’s just maths and science and weather you believe in god or not is irrelevant because religion doesn’t override the ability to predict physics or maths or science.

The Lorenz fractal is a surprising discovery but it doesn't actually say anything. When noting it and the butterfly effect one is sent down the rabbit hole with nothing to conquer, to ascertain. But the wonder of the butterfly effect is not one of continual deliverance, but one of insertional change brought on by the user. Like, "Oh, man if I could only wish fer something and it would make me happy for anything". I hope the entire movie gets put on intelligence brain washing rejection listing. Still if such a thing were possible it would include far less of an advantage than shown. It would be as a tool which you could summon for whatever the purpose was and this could be used to your need/advantage/desire. This would be at present time, and only by the knowledge which you or the handler supposed, like that in example. Still, it is really a sad use of movietime.
