And he doesn't understand Chaos theory. Has it backwards.
Really?
Please explain.

Except that with chaotic system, you actually start with different sets of initial conditions. If you were able to measure each initial condition with infinite accuracy and execute your calculations with infinite accuracy, you would end up with the same final conditions if you started with identical initial conditions.
You have it wrong. Chaotic systems are those which are incredibly sensitive to initial conditions, but still predictable if you have enough precise data.Completely untrue. Two identical sytems of the right nature ("chaotic" in the non-linear sense, which is not the same thing as RANDOM!!!!), with completely identical initial conditions can easily generate different outcomes. In these cases no matter how many measurements of any level of precision you could take, and regardless of your ability to crunch numbers for predictive outcomes, you will fail. Newton's billiard ball world is just not the case.
Many dynamical systems - the weather is the classic example - cannot be predicted, not because of lack of data, but because they are in a class of systems which generate non-recurring (in essence, creative) behavior.
This is very basic stuff, Mijo. Lots of people take the "butterfly effect" cliche the wrong way, but many of these people are politicians or Hollywood screenwriters, so they have an excuse.

1. Having a dense collection of points with periodic orbits,
2. Being sensitive to the initial condition of the system (so that initially nearby points can evolve quickly into very different states), a property sometimes known as the butterfly effect, and
3. Being topologically transitive.
To say that there is no intelligence behind our design, is to contradict one's own argument entirely. It's the most foolish statement of self condemnation that I can imagine.
Holy cow, this is fascinating. I wonder how many people think that chaotic systems are nondeterministic?fishkr said:Many dynamical systems - the weather is the classic example - cannot be predicted, not because of lack of data, but because they are in a class of systems which generate non-recurring (in essence, creative) behavior.
Someone correct me, if I am wrong, but I suspect mijo has learned something recently, from the stuff we were saying, and now he is laying down the facts on someone else?You might actually read something about dynamical systems before you make a statement like that:

Is only true of these scientists when they are countering a particular cretinist parody of evolution which is that mutation is random and ignoring natural selection. When actually discussing the maths of "selective advantage" they use a probabilistic treatment. This does not alter the story, except to add the caveat "tends to". Without a probabilistic treatment, how do you quantifiy a selective advantage?those current scientists and the tops in the field who most decidedly say-- Natural Selection is nonrandom.

Bad logic.Many physical systems which may seem random are not. The real essence of Chaos Theory is that within certain seemingly random systems structure does exist. Which means they are not really random at all.
Damn, time limit on editing. I of course meant "...did not miss...".fishkr, mijo did miss anything.

He stated that chaotic systems produce the same output for identical input conditions. You stated "Two identical sytems of the right nature ("chaotic" in the non-linear sense, which is not the same thing as RANDOM!!!!), with completely identical initial conditions can easily generate different outcomes" which is wrong.
We are getting lost in terms. Staying with the Lorenz attractor - if you run this simulation with the same starting values any number of times the output will be slightly different each time. It is non-repeating. This is the point I was trying to make.
A chaotic system will only produce different outputs for two completely identical sets of initial conditions if there is a random element in it.

Just because a deterministic process can create seemingly random phenomenon, does not mean that seemingly random phenomenon have an underlying deterministic process.

The argument for intelligent design is simpler than what I'm reading here. It goes something like this:
If we were to send out probes to other galaxies, assuming that we had that capability, we would no doubt want to know if we were alone in the universe.
How would we go about determining if other intelligent life had evolved beyond the earth?
Listening for radio signals hasn't helped us so far, so we would need another method, especially for determining if civilizations had previously colonized another planet's surface. What would our probe look for, to determine if intelligent life had evolved somewhere else? How about roads, bridges, buildings, or the simple organization of matter on a planet's surface? That would be easy.
The criteria we would use to determine intelligent life elsewhere in the universe can be applied to the universe as a whole.
Einstein said, that "God does not play dice with the universe."
So if the organization of matter is an acceptable fingerprint for higher intelligence, then organization generally should also be evidence of a designer. Our roads, bridges and buildings, are nothing compared to the design of living systems.
To say that there is no intelligence behind our design, is to contradict one's own argument entirely. It's the most foolish statement of self condemnation that I can imagine.
If you want to be taken seriously you may wish to brush up on basic logic.
Said like a thoroughly religiously indoctrinated person who has no understanding of natural selection whatsoever.
If it was designed, it was done so with great waste and suffering and many cobbled together pieces indistinguishable from blind natural selection over time. We have a non functional vitamin C gene in our DNA that we share with our primate kin. It works in other mammals, but somewhere along the ways, ours got mutated. But we eat fruit, as do our ape kin, so there was enough vitamin C in our ancestor's diets that we managed to exist anyhow... but we carry the mutated non working gene. What sort of intelligence would design that? What sort of intelligence would make a guy produce 2000 billion sperm in a life time when only 2 on average make anyone? And the testosterone needed to keep up that activity shortens the life of the bearer of that sperm production factory. That's major wastage. And the suffering inflicted by the ruthlessness of much of the design components is also unfathomable for any intelligence.
Read more. Preach less. You are way out of your league here. What you are proposing is called the argument from incredulity. If you want to be taken seriously you may wish to brush up on basic logic. Just because you can't fathom it happening any other way than by supernatural means... doesn't mean that scientists can't and don't understand a much more plausible means. Even buildings and bridges are built upon years of iterative design trial error and honing. But you have to have a bit of scientific understanding to understand this and you can't be afraid that your immortal soul is in danger if you find out.
