1.3 The Problem

I recently tried, once again, to correct misleading information on the Wikipedia article 'Entropy'.. the article reads as follows.. (yellow highlight mine)

According to the second law of thermodynamics the entropy of an isolated system never decreases, because isolated systems spontaneously evolve towards thermodynamic equilibrium, the configuration with maximum entropy.

Note the use of the word "evolve".. Here are the dictionary definitions for the word 'evolve'..

The Science Dictionary
    To undergo biological evolution, as in the development of new species or new traits within a species.

    To develop a characteristic through the process of evolution.

    To undergo change and development, as the structures of the universe.

Example sentences
The world-and the employment marketplace- evolve  and progress. Superbugs evolve  when common bacterial infections develop resistance to the

Dictionary.com

1. to develop gradually: to evolve a scheme.
2. to give off or emit, as odors or vapors.

verb (used without object), e·volved, e·volv·ing.
3. to come forth gradually into being; develop; undergo evolution: The whole idea evolved from a casual remark.
4. Biology . to develop by a process of evolution to a different adaptive state or condition: The human species evolved from an ancestor that was probably arboreal.
Not only is DEVELOP the dominant synonym.. its also tied to PROGRESS both implying improvement in the quality of some given aspect.. re-enforced by

Thesaurus
1. a. To develop or achieve gradually: evolve a style of one's own.
    b. To work (something) out; devise: ...
2. Biology To develop (a characteristic) by evolutionary processes. ...

1. To undergo gradual change; develop: an amateur acting group that evolved into a theatrical company.
2. Biology To develop or arise through evolutionary processes. ...

Let me make it VERY CLEAR isolated thermodynamic systems DON'T IMPROVE in any way.. They DECAY from 'interesting' to 'boring' equilibrium.. where they stay.. However when I point this out.. in jump the hard liners, the old guard rusted on - to evolutionist dogma.

This is the new dark age..

1.2 The Problem

Sorry folks for the long delay in posting.. I am embroiled in a huge mess which resulted in a court case with the Australian Civil Aviation Safety Authority (CASA) concerning my J2 gyroplane.. So I'll be brief..

Even though we have difficulty actually saying what 'energy' is.. we all pretty much understand what it can do. It can manifest itself as a property of matter (temperature, speed etc) or it can just propagate itself through space at the ultimate speed of anything as electromagnetic radiation. But even light has a small amount of 'momentum', which is calculated as mass x speed so it seems photons of light either have some mass or apparent mass. And of course everyone knows of Albert Einstein and his equation E = MC^2 which, notwithstanding atomic bombs, is a fairly deep concept.

Well that's all very fine but what about Entropy..? and who has even heard of Ludwig Botzmann let alone his most famous equation..
s = k.ln W (s = entropy)? Hardly any student at high school I have met is remotely aware of it! Yet it is just as important.. Progress in technology is constrained to meet several criteria but three substantial barriers are common to all..

(1) ENERGY.. we do not have an energy crisis, its an entropy crisis, plenty about but most of it is unavailable

(2) RELIABILITY.. how long can it hold off the law of increasing entropy

(3) COST.. can we afford it.

Which is why for instance electric cars struggle to make it in the market.. How to have enough 'light' batteries to give the power required with long enough service life and low enough replacement cost.. for like us, they will die.

If the understanding of entropy is of major importance.. why don't school kids know about it and why is the Wikipedia such a mess?
