If a woman falsely accuses us of fathering her child , we will
use DNA testing to prove it false.
Why then do the religious refuse DNA evidence that we are the
closest relatives of chimps? In fact there was a lot of breeding
between the two until a few million years ago , and maybe possible
even today. |

Not so. We are routinely applying reason to discuss processes
which as such are not necessarily created by any acts of reason.
Any physical law can be used as an example. Life is just one
of such processes. Thermodynamics is an external treatment to all
processes (including Life) therefore it can be used to show why process
takes place.
Here is example of such "why" explanation: Reaction O2 + H2->H20
takes place at given temperature T and pressure P because
change of dG=dH - TdS from left to right is negative under this conditions.
The same approach can be applied to process "Life", except treatment
will include 3 steps:
1) reaction A + B --> C has dG1<0, however it is slow without
catalyst
2) catalyst L is thermodynamically unstable, e.g.
L + environment --> decomposition products has dG2>0
3) abs(dG1)>abs(dG2) therefore in presence of 1) reaction 2) can
be reversed (excess of dG1 is used to apply work to conteract dG2),
which means L is stabilized as long as A+B are present.
Above 3 points is a formula of Life (which is the conditionally stable
catalyst "L"). Its existence does not require any external "reason".
It does require that thermodynamics laws are correct, however these
laws are purely statistical in their nature and are therefore a-priory
correct.
We do have to apply reason to understand why this process takes place,
however.

Evgenij |

Hi Tom_Davidson, I wrote:
To hate entroy is to hate yourself,
for 'twas entropy that created everything, inclusing yourself.
Zoom out a bit, and you can see evolution... you're related to apes.
Zoom out a bit more and you see that you're like a lit match,
where consumption ( entropy, dissipation ) creates/destroys all that is.
Entropy is the God of Gods.
And you replied:
Spoken like a faithful worshipper of Shiva: WikiPedia.ORG/wiki/Shiva
Yes, while I haven't worshiped a stone phallus lately,
pantheistic ideas like mine ( and Einstein's )
were recorded thousands of years ago. See: WikiPedia.ORG/wiki/Pantheism
Ironically, some people accuse me of being a kook and a crank,
coming up with Woolly_Ideas and, ha ha, Original_Research.
Speaking of entropy, consumption and dissipation,
the cosmological constant explains ongoing inflation:
Spacetime accrues according to the Density_of_Matter;
so our observable universe cooled faster when Density_Matter was higher.
In other words, mass-energy spontaneously dissipates.
Omega_Total = 1, meaning there is is no center of gravity.
So, by General_Relativity's field equations of the cosmos and e = m * c^2,
Negative_Pressure = Negative_Energy = Inflation.
The equation of state, w, is always -1 ; Omega_Lambda is always .74 ;
Pressure_Cosmos = - ( .74 / .26 ) * Density_Matter * c^2 ; So:
The positive pressure of radiation is insignificant.

Hi Evgenij_Barsukov, When I say life is like a lit match,
that is, of course, merely a model... sans detail.
Your model emphasizes the ignition of the match,
because it is, to be sure, the least spontaneous aspect.
Eu-Life does not require liquid water, no doubt. |

A lit match consumes air and wood... so it's a fair model of life, I say.
What's warped about it ?

Hi Tom Davidson, Attempting to flame as well as
Gisse, T_Wake, Art_Deco, Crank_Seeker and T_Duckie, You told me:
Has it *yet* occurred to you that many here in the physics groups do
not care what you write because it fails to convey any physics ?
First off, since 1991, I've been flamed by the best,
and none of the people I've mentioned here are the best at it.
Second, take a look at the physics in this .PNG file,
containing ESA.INT facts: www.Cotse.NET/users/jeffrelf/W.PNG
Here's some more empirical physics for you:
( because I know you can't get enough )
Large Synoptic Survey Telescope
The Large Synoptic Survey Telescope (LSST) is
a planned wide-field "survey" reflecting telescope
that will photograph the available sky every three nights.
Construction should start in 2009 with completion in 2012.
The telescope will be located on Cerro Pachón,
a 2,700 metre high peak in northern Chile.
The LSST is unique among large telescopes ( 8m-class primary mirrors )
in having a very wide field of view 3.5 degrees in diameter
( 9.6 square degrees [ 40 moons ] ).
For comparison, both the Sun and Moon, as seen from the Earth,
are .5 degrees across. Combined with its large aperture
( and thus light-collecting ability ), this will give it
a spectacularly large etendue of 318 m^2 * degree^2.
To achieve this very wide undistorted field of view requires
three mirrors, rather than the two used by most existing large telescopes:
the primary mirror will be 8.4 meters in diameter,
the secondary mirror will be 3.4 metres in diameter, and
the tertiary one will be 5.0 metres in diameter.
The primary mirror will be built by the Mirror Lab at
the Steward Observatory in Arizona.
A 3.2 billion-pixel prime focus digital camera will take
a 15-second exposure every 20 seconds.
Allowing for maintenance, bad weather, etc.,
the camera is expected to take over 200,000 pictures
( 1.28 petabytes uncompressed ) per year, far more can be reviewed by humans.
Managing and effectively data mining the enormous output of the telescope
is expected to be the most technically difficult part of the project.
Particular scientific goals of the LSST include:
* Measuring weak gravitational lensing in the deep sky
to detect dark energy and dark matter.
* Mapping small objects in the solar system,
particularly Near-Earth asteroids and Kuiper belt objects.
* Detecting transient optical events such as Novae and Supernovae.
* Mapping the Milky way.
It is also hoped that the vast volume of data produced will lead to
additional serendipitous discoveries.
Synoptic is an adjective from the same root as the noun "synopsis",
and means "relating to data obtained nearly simultaneously over a large area."

The thermodynamical definition of Life makes is very clear
that it has nothing do do with water, proteins etc etc.
The only requirement for Life is a presence of matter
which entropy increase can be accelerated. Here I understand
entropy in a wider sense than it is used in chemistry, as
"total degrees of freedom" of a system (including quantum
states which are not accessible through
chemical reactions and are therefore hidden in dH, as well
as sub-nuclear degrees of freedom).
So entropy increase does include for example nuclear reactions,
dropping matter into a black hole (60% of energy is getting
irradiated as light, hugely increasing entropy of the system)
or any other entropy increasing (e.g. spontaneous, irreversible)
processes imaginable.

Evgenij |

Logical fallacy based around the fact the analogy is "false" (insofar as an

Nothing. I said _you_ were warped.

It is very Earthbased-life-centric though. It is beyond the realms of
science to discuss the possibility of some unusual circumstances allowing
"life" to exist.
We discuss "lifetimes" of a vast array of non-liquid-water-requiring things.
Even stars have a "life cycle" in which they are born, age and die. How is
that very different from human life - taking your child like model as an
example.

You are too concerned with appearing deep and philosophical. I bet you wish
you were 10 years older so you could have sat round coffee shops in a French
beret and quoted poetry or philosophy at the young impressionable girls. |
