Actually I meant dichotomy :-}. But then I was not expressing how I think
about things, just an impression about how some may be thinking about art;
I mean in the same way that some "pure" mathematicians seem to frown upon
practical applications, because the concept is everything.
BTW I finished my semester last monday. Yay! (and that's my excuse for

If you don't have any conceptions about the world, then when things
happen, you cannot have predicted them nor say that in retrospect they
were likely to happen. Therefore you don't have anything to say about the
world. That's why the conceptions are essential. Separating yourself from
the conceptions, you cannot say much more than that there exists a world
that you can have conceptions about, and that there exist different
conceptions, and that one's conceptions change over time. (And I guess
even that could be disputed.)

Informatics, from French "informatique". Where I live, a compsci
bachelor's degree is called a "baccalauréat en informatique".

Which is why, in practice, several models of different levels are
superimposed and used simultaneously, and then one chooses the model that
best fit a problem or discourse; like, chemistry and classical physics are
now considered to be consequences of quantum physics, but still we use the

The domain over which uniform noise is uniformly distributed is a pattern
of the noise.
Now if you are looking for a domain the least "patterny" possible, maybe
you'd try the biggest possible domain in a given context, but usually it
does not make sense; for example, uniformly distributing noise over all
natural numbers (or all real numbers) is a mathematical contradiction.
> Or is all noise also chaos? (structure and indeterminacy)
What is considered noise is relative to the observer, and in particular to
its ability to see patterns in it, and its willingness to do so.
I don't think you can prove that there exists an absolutely unpredictable
source of data, and I don't think you can prove that there doesn't exist
any. Those are largely metaphysical questions.
> What is the lyapunov (measure of chaos) exponent of white/brown/pink
The concept of "chaos" as found in mathematics is not founded on
randomness at all. It merely refers to how, often, knowing the rules of a
system doesn't mean that you can make much accurate predictions about it.
Now, if you have a source of white noise, then by definition, the only
knowledge you have of white noise values is their probability
distribution; for if you happen to know anything else about how those
values go about, it's not white noise to you anymore, as its values are
not independent from each other.
Therefore you can compute a Lyapunov exponent on white noise iff you can
do it only considering its probability distribution; and briefly looking
at what the definition is, I don't think it makes sense at all to try to
find a Lyapunov exponent on white noise.
