That's not true at all. That's a problem of complicated systems, not chaotic ones.
Again, the logistic map is quite simplistic:
xn+1 = rxn(1 - xn)
We know all the variables, but when r is about 3.54, the system is chaotic. It isn't that we don't know all the variables involves. It's that the system is so sensitive to initial conditions that being off by a tiny amount will result in vast differences down the line.
quote:
I don't know where you got the idea that knowing more variables in the initial condition makes little to no difference in the prediction of a chaotic system.
Because chaos has nothing to do with the number of variables. You can get chaos from a single variable. It has to do with the sensitivity of the variables.
A system can be both complicated and chaotic.
And weather is not climate.

Thank you for your submission to Science. Your paper was reviewed by a jury of seventh graders so that they could look for balance and to allow them to make up their own minds. We are sorry to say that they found your paper "bogus," specifically describing the section on the laboratory work "boring." We regret that we will be unable to publish your work at this time.

Re: Question
xn+1 = rn(1 - xn)
Thank you, I was trying to remember that.
Edit Actually this is all off topic, so I'm going to drop it now. New thread, etc. if anyone wishes to pursue the matter?
Edited by Mr Jack, : Off Topic.

*blink*
You did not just say that did you?
Ok, sorry. Had to do it.
You're absolutely right. I was partly misinformed about that.
However, my original argument still stands. The weather is a chaotic system because it is highly sensitive to initial conditions. It is also very complicated because there are just too many variables in the equation.
I guess I was mashing the two characteristics together.

Owing to the deficiency of the English language, I have occasionally used the academic jargon generator to produce phrases that even I don't fully understand. The jargons are not meant to offend anyone or to insult anyone's intelligence!
