##### if entropy is pure then how does evolution occur?
« on: 21/07/2008 15:21:06 »
How is it possible that if chaos and equilibrium are laws of physics

then how can evolution occur and life continue for billions of years reflected in the tree of life and sharing that it is in a continuous evolutionary process (its still alive)?

Because the second law of thermodynamics says that the entropy of an isolated system not already in equilibrium will tend to increase over time.

Living organisms aren't isolated systems.  They are constantly taking in energy from their environment, so their entropy doesn't have to be increasing.  Most of this energy has come from the sun, though some comes from the earth itself.  If you lump together life forms on earth, the earth itself, and the sun into one "system" then you'll see entropy increasing over time, since together these make up a system that is (pretty close to being) isolated.

so share a living system in a pietry dish and forget the sun.

the point is; life has a purpose

and the life of a person for example is his intent as when sleeping or dead; there be no more intent of the consciousness.

so the same mass is put into the ground upon death; but the life is gone.....

what is that life?

that is the point..... the energy upon mass has a set of laws and them laws are not singularly entropy or determined in direction....

that is the beauty of life; there is an intent

and there is only one method of reflecting this mathematically and it comes from maintaining the entanglement of the environment

which in reality that entangled energy is that phenomenon known as gravity.....

If you shake up a large bag of letters you should not be surprised to come across the word "Bullshit" once in a while. The other letters would be pretty well jumbled, though.
That would prove nothing, though.

btw, your petri dish would contain some nutrient, which got its energy from the increase in Entropy, some while ago, in the Sun.

This "what is that life?" is a good question.
However the answer has nothing to do with thermodynamics.

if the 2nd law has to do with the core of how energy is defined in the math of science; then how can you suggest that?

how can we hold in our hands a living form and then suggest, that the energy upon that life, is not important

touche my boy! (sorry about the missing accent)
But you, surely, must appreciate my point. The fact is that some of the numbers involved in the probability of certain things happening are too big to consider dispassionately. We then tend to look for magic rather than reason.

Why are people not prepared to accept that this is where we are and this is the state of things because it just IS? Why do we assumed that there are answers to and reasons for everything or that we can hope to understand it all?

Yes, life's great but we are part of it and, we wouldn't be thinking about it if we didn't exist. I am quite prepared for the fact that it is just a happy coincidence.
