Chaos made simple

This shows a lot of tiny particles moving around.   If you were one of these particles, it would be hard to predict where you'd go.  See why?  It's because each time you approach the crossing, it's hard to tell whether you'll go into the left loop or the right one. 

You can predict which way you'll go: it's not random.  But to predict it, you need to know your position quite accurately.  And each time you go around, it gets worse.  You'd need to know your position extremely accurately to predict which way you go - left or right - after a dozen round trips. 

This effect is called deterministic chaos.  Deterministic chaos happens when something is so sensitive to small changes in conditions that its motion is very hard to predict in practice, even though it's not actually random.

This particular example of deterministic chaos is one of the first and most famous.  It's the Lorenz attractor, invented by Edward Lorenz as a very simplified model of the weather in 1963.

The equations for the Lorentz attractor are not very complicated if you know calculus.  They say how the x, y and z coordinates of a point change with time:

dx/dt = 10(x-y)
dy/dt = x(28-z) - y
dz/dt = xy - 8z/3

You are not supposed to be able to look at these equations and say "Ah yes!  I see why these give chaos!"   Don't worry: if you get nothing out of these equations, it doesn't mean you're "not a math person"  - just as not being able to easily paint the Mona Lisa doesn't mean you're "not an art person".  Lorenz had to solve them using a computer to discover chaos.  I personally have no intuition as to why they work... though I could get such intuition if I spent a week reading about it.

The weird numbers here are adjustable, but these choices are the ones Lorenz originally used.  I don't know what choices David Szakaly used in his animation.  Can you find out?

If you imagine a tiny drop of water flowing around as shown in this picture, each time it goes around it will get stretched in one direction.  It will get squashed in another direction, and be neither squashed nor stretched in a third direction. 

The stretching is what causes the unpredictability: small changes in the initial position will get amplified.  I believe the squashing is what keeps the two loops in this picture quite flat.  Particles moving around these loops are strongly attracted to move along a flat 'conveyor belt'.  That's why it's called the Lorentz attractor.

With the particular equations I wrote down, the drop will get stretched in one direction by a factor of about 2.47... but squashed in another direction by a factor of about 2 million!    At least that's what this physicist at the University of Wisconsin says:

J. C. Sprott, Lyapunov exponent and dimension of the Lorenz attractor
http://sprott.physics.wisc.edu/chaos/lorenzle.htm

He has software for calculating these numbers - or more precisely their logarithms, which are called Lyapunov exponents.  He gets 0.906, 0, and -14.572 for the Lyapunov exponents.

For more nice animations of the Lorentz attractor, see:

http://visualizingmath.tumblr.com/post/121710431091/a-sample-solution-in-the-lorenz-attractor-when

David Szakaly has a blog called dvdp full of astounding images:

http://dvdp.tumblr.com/

and presumably this one of the Lorenz attractor is buried in there somewhere, though I'm feeling too lazy to do an image search and find it.

To Species' wiki Subject page - http://worlduniversity.wikia.com/wiki/Species - for open teaching and learning at World University? Planned in many languages ... 
It's that time of year again: the time when a young pinniped's fancy turns to thoughts of lounging around on the beach. And what better way to celebrate high summer in the Arctic than with WalrusCam, a continuous live stream from Round Island, Alaska, where you can hear the soothing sounds of the waves crashing on the shore as thousands of tons of blubber, muscle, and tusk photosynthesize and lumber about?

And by thousands, I mean thousands; there can be as many as 14,000 walruses, each weighing a good two tons, on this island at a time. It's kind of fascinating.

Alas, the video link on the page below seems to have expired; you can see the current WalrusCam at https://www.youtube.com/watch?v=-XizvosHgHQ .

Hi i Q, S, L and Wikidatans, 

In terms of strategic partnerships with CC Wikidata, and this Wikidata Engineering Community project looking for -

 "* people that have been in touch with organizations willing to contribute their open data" - 

in what ways could CC World University and School contribute our early CC Nation State Universities, e.g. Mexico World University and School - http://worlduniversity.wikia.com/wiki/Mexico - (with only the CC MIT OCW in Spanish so far, and not yet in Spanish otherwise)? See also, for example, the Nation States' wiki subject page at WUaS - http://worlduniversity.wikia.com/wiki/Nation_States. Each wiki Nation-State University at CC WUaS, seeks to accredit in each country in their main languags to offer online CC baccalaureate, Ph.D., Law and M.D. degrees, and also I.B. high school degrees, if possible, based on CC MIT OCW in 7 languages and CC Yale OYC, to begin. 

In addition, CC World University would like to facilitate wiki / Wikidata schools for open teaching and learning in each of all 7,929+ languages. As planned interlingual wiki schools for highest quality universal education, CC World University and School would like to explore developing in Wikidata, and become a growth story also for Wikidata. World University would thus like to explore contributing our open data in these regards. 

In what ways might WUaS best contribute in terms of a strategic partnerships re this Wikidata Engineering Community project ? Perhaps World University could become a part of the"community framework allowing Wikidata content and tech contributors, data engineers, and open data organizations to collaborate effectively." Thank you.

Best,

To Medicine at Wotld Uni?
In excellent news of the day, California SB277 has just been signed into law: all non-medical exemptions for school vaccination requirements are now gone. California has several hubs of people who have been refusing critical vaccinations based largely on rumors that They're Bad For You, and has had serious outbreaks of diseases like measles and pertussis as a result. 

No more. The personal and religious exemptions (basically, the "I don't wanna" exemptions) have been eliminated.

I'm incredibly happy to see the state legislature move so quickly on an issue that put thousands of lives across the state at risk.
