Honestly, can people please stop making such great avatars, these decisions are too hard... :klingon:


EDIT: Also you've used the wrong image for Zion's entry. He said he wanted this one

captcalhoun, trekkiedane, trampledamage(That double egg yolk looks tasty, i can almost taste a fresh slice of bread and butter dipping into it:drool:).
 
Aragorn, I Am Legend & Kestra.

I had a different one chosen too...but then again I post 3. :lol:

I will stick with it. :bolian:
 
Seriously, these contests seem to get more difficult every time. The Voting, I mean. I got a kick out of the little comments in the Poll. :rommie:

And ZR's entry is fixed.
 
Right, finally narrowed it down to three. I need to sit down and have a rest - that was hard work!

trekkiedane
RJDiogenes
I Am Legend.
 
auntiehill
Kestra

Nice poll tharpdevenport :bolian:

And my thanks to: Haggis and tatties, I Am Legend, OldSmokey, Omnius, tharpdevenport, thestrangequark, trampledamage and Zion Ravescene
 
Well I'm stunned that so few enjoy the subtleties of the double pendulum, and can't fully appreciate the two linearly independent periodic modes the system exhibits in the limit of small angles, viz;

(mode 1)
theta2 = sqrt(2) * theta1 ; frequency = f

(mode 2)
theta2 = -sqrt(2) * theta1 ; frequency = 2f

;)

Perhaps if you twisted a few people's arms... ;)

For a chaotic system your entry did seem a little ... hmmm ... lacking in the chaos department ;)

In the limit of small angles, sin(θ) --> θ, cos(θ) --> 1, which makes the governing equations linear, which does not exhibit chaotic behaviour. It is much like a coupled spring system.

But even in the general case, chaotic systems can still have periodic orbits. They are dense and unstable so no real world experiment would ever reveal them; the only attractors being the chaotic attractors.

One of the best demonstrations of this is in one dimensional IFS systems, where the Sharkovskii theorem applies: If a system has a period three orbit, then the system will have a chaotic attractor and will also have an infinite number of periodic orbits of all periods. So somewhere within it there would be an orbit with a period of one googolplex.
