The motion of both can be well described by Napier-Stokes equations which
describe fluid flow using Newton's laws, and DNA being more viscous than
water the resulting equations would be simpler than the ones for water.

You've got to play fair, it you talk about micro states for DNA I get to
talk about micro states for water.

Somehow I'm not surprised, and it's Shannon Information Theory.

OK, although I don't see what purpose the word "further" serves in the
above, and although I know all about Claude Shannon the term "Shannon
information" is nonstandard. What would Non-Shannon information be?

What on Earth are you talking about?? The more entropy a system has the
more information needed to describe it.

I see, it has high information and less information. No I take that back, I
don't see, although it is consistent with your usual logical standards.
> Easier to compress does *not* mean less information
It means a message has been inflated with useless gas and a compression
program can remove that gas and recover the small kernel of information
undamaged. White noise has no gas in it for a compression program to
deflate, that's why if you don't know the specific compression program used
the resulting file ( like a zip or gif file) would look like random white
noise, and yet its full of useful information if you know how to get it.
The same thing is true of encrypted files, if the encription is good then
the file will look completely random, just white noise, to anyone who does
not have the secret key.

How do you expect mathematics to deal with anything as subjective as
quality? A novel that's high quality to you may be junk to me.

I've never heard of religion saying anything wise, philosophy does contain
wisdom but none of it came from professional philosophers, at least not in
the last 300 years.

As you've said before, but saying it does not make it so.

Then the human mind works very inefficiently and needs improvement.

Even asterisks do not make it so.

I don't think it's an exaggeration to say that if you wish to understand
how mind works the verbiage generated by 99% of the people on this planet
will be of no help to you whatsoever; better to listen to what the experts
have to say about the subject.

I see, it has more information but that doesn't mean it has more
information. No I take that back, I don't see, although it is consistent
with your usual logical standards.
