There are 179706 comments on the www.scientificblogging.com story from Feb 24, 2008, titled Should evolution be taught in high school?. In it, www.scientificblogging.com reports that:

Microbiologist Carl Woese is well known as an iconoclast. At 79 years of age, Woese is still shaking things up. Most recently, he stated in an interview with Wired that...

"My feeling is that evolution shouldn't be taught at the lower grades. You don't teach quantum mechanics in the grade schools. One has to be quite educated to work with these concepts; what they pass on as evolution in high schools is nothing but repetitious tripe that teachers don't understand."

Sofar. Entropy.
A measure of the disorder of a system.

A measure of the amount of energy in a system that is available
for doing work; entropy increases as matter and energy in the
universe degrade to an ultimate state of inert uniformity.

Differentiation of Heat (Q), dQ, is not an exact differential and
therefore cannot be integrated. Therefore we introduce an
integration factor (1/T) such that dQ/T can be integrated. And this
dQ/T is called entropy.

So even though Log W=o the amount of energy expended could differ.

Establish the link between statistical entropy and physical
entropy.
Without additional information about the die, the most unbiased distribution is such that all outcomes are equally probable.

P(X =1)= P(X = 2)=...= P(X = 6)=1/ 6
Shannons Measure of Uncertainty
Shannon [1948] suggested the following measure of uncertainty, which is commonly known as the statistical entropy
1. H is a positive function of p1, p2,, pn.
2. H = 0 if one outcome has probability of 1.
3. H is maximum when the outcomes are equally likely.
In the case of the die, you will find the maximum entropy to be
H = ln6
Stirling approximation: ln(N!)= N ln N - N, for very large N
Conclusion:
ln omega=NH
ln omega is linearly proportional to H. Therefore, maximizing the
total number of possible outcomes is equivalent to maximizing Shannons statistical entropy.
Statistical Entropy-> H = Const X ln omega <-# of possible outcomes

Entropy in Statistical Physics
Definition of physical entropy:

S = const X ln omega, omega =# of possible microstates of a close system.
A microstate is the detailed state of a physical system.
Example: In an ideal gas, a microstate consists of the position and velocity of every molecule in the system. So the number of microstates is just what Feynman said: the number of different ways the inside of the system can be changed without changing the
outside.
Principle of maximum entropy (The second law of thermodynamics)
If a closed system is not in a state of statistical equilibrium, its macroscopic state will vary in time, until ultimately the system reaches a state of maximum entropy.
Example:
S = Const x ln (# of Velocity States X # of Position States)
# of velocity states does not change.
# of position states does change

delta S = S2-S1 = const x {ln(2V)^N - lnV^N}= const X Nln2
Moreover, at equilibrium, all microstates are equally probable.
Temperature:
Temperature T is defined as

1/T = dS/dE . The temperatures of bodies in equilibrium with
one another are equal.
Since T is measured at a fixed number of particles N and volume V, a more stringent definition is

T =(dE dS)N,V .
Thus far, S is defined to be

S = const X ln (omega).
If S is a dimension-less quantity, T has the dimensions of energy (e.g. in units of Joules (J)).
But J is too large a quantity. Example:
Room temperature = 404.34 x 10-23 J !
What is the physical unit of T?
It is more convenient to measure T in degrees Kelvin (K). The conversion factor between energy and degree is the Boltzmanns constant, kB = 1.38 X 10-23 J / K. Hence we redefine
S and T by incorporating the conversion factor.
S = kBln omega and T = T/ kB
Using the Boltzman factor:
Same change in entropy, but more energy is given away by the system initially with higher T. Hence temperature is a measure of the tendency of an object to spontaneously give up
energy to its surroundings.

Boltzmann and Gibbs Distribution used.
Goal: Describe the probability distribution of a molecule of interest, with energy Ea , in equilibrium with a macroscopic thermal reservoir with energy Eb.

The second law says that at equilibrium, or
maximum entropy, all microstates are equally
probable, with a probability P0.

The first-order Taylors expansion is used to approximate SB(EB) because EB is very near
Etotal.
IMPORTANT: The probability distribution of the molecule of interest in equilibrium with its surrounding depends only on the temperature of the surrounding.

High energy barriers would require specific high energy pathways (catalyst)

The pain VR1 receptor, reacting on raising of temperature is a slow system.

(b) The probability that an introduced species
succeeds in establishing naturalising and spreading

THe Oort Cloud is hypothetical and has never been observed. But pop magazines keep exaggerating claims so people like you drink the Kool-Aid.

The Oort cloud /&#712;&#596;rt/[1](na med after the Dutch astronomer Jan Oort), or ÖpikOort cloud,[2] is a hypothesized spherical cloud of predominantly icy planetesimals that may lie roughly 50,000 AU, or nearly a light-year, from the Sun.

Although no confirmed direct observations of the Oort cloud have been made, astronomers argue that it is the source of all long-period and Halley-type comets entering the inner Solar System and many of the centaurs and Jupiter-family comets as well.

Nuclear fusion has never been "observed" in the interior of the Sun, but there are no other logical explanations for the properties of the sun based upon its observations.

ISON's orbital eccentricity is evidence that it does not come from the region of short-period comets in the Kuiper belt. Note the word "BELT". The term belt suggests a more two dimensional property that the Kuiper belt exhibits, laying on, and similar to the orbital plane that the planets fall on. Comets coming from the Kuiper belt

The Oort "CLOUD", on the other hand surrounds the entire solar system. Comets can come in from the Oort cloud from angles impossible for Kuiper belt objects to originate from.

It's the observed, measured orbital eccentricity of ISON that defeats you.

"C/2012 S1 will come to perihelion (closest approach to the Sun) on 28 November 2013 at a distance of 0.0124 AU (1,860,000 km; 1,150,000 mi) from the center point of the Sun.[3] Accounting for the solar radius of 695,500 km (432,200 mi), C/2012 S1 will pass approximately 1,165,000 km (724,000 mi) above the Sun's surface.[13] Its trajectory appears hyperbolic, which suggests that it is a dynamically new comet coming freshly from the Oort cloud.[14][15]"

That's what I get for trying to watch tv and respond at the same time.

EDIT: "Comets coming from the Kuiper belt"...*will come in on highly eccentric orbits*, indicating a fairly local origination.

EDIT2: "The Oort "CLOUD", on the other hand surrounds the entire solar system". It is a "CLOUD" (as opposed to a "belt" that encompasses the solar system from every angle. Comets CAN come in from every angle, and when they do, will come in with a very low eccentric orbit*

What critical part? There is a slight variation, no problem. Variations accumulate in an interbreeding population, always within the limits of compatibility.

Only when that isolated population meets another have the combined accumulations of change been enough to prevent interbreeding.

Its really no different than the development of accents, then dialects, then languages.

Where is the problem?

In math terms it's like saying that "2" has a mechanism for not being "3". In reality, it just isn't.
I like your analogy with the numbers. It maybe that some reproductive incompatibility results just as you say, but any barrier mechanism with a genetic basis would be subject to selection pressure.

If a two species are physically able to interbreed, but do not produce viable offspring, they are expending resources for these unproductive reproductive events. Breeding has costs associated with it including mate finding, courtship, nesting, periods of gestation, physiological stresses and so forth. If there are not barriers at some point in the process, a lot of inputs are wasted and fitness is reduced.

He is talking about geographic speciation. Also known as allopatric speciation. A geographical barrier separates two or more populations and eventually they can become different species. The mechanisms you are referring to, may or may not develop depending on selection pressure for the development of those mechanisms. Evolution can occur with or without the presence of the mechanisms you refer to.

You seem to just talk right out of your ass-all the time.
Remember, YOU are the one making the specific claim that its not possible, while you are no more knowledgeable about the species-specific mechanism than I am.

But whether or not we know the specifics in this case, we do know how evolution is supposed to work. We do know that change is cumulative. If two populations have speciated from a common ancestor, we know it had to happen by small degrees over many generations.

Therefore when you present a problem that is easily explicable by this mechanism, whilst making the claim that it refutes evolution, I merely need to point out that evolution's mechanism accounts for it easily.
