| The gist of Daniel Styer's argument from his 2008 article "Entropy and Evolution", wherein he uses Boltzmann entropy to calculate the entropy change of an organism evolving and biosphere as a whole, which he says does not conflict with the second law; which in 2012 worked to initiate the Roemer-Styer fiasco carried about via the efforts of American noma creationism physicist David Roemer, who considers Styer's calculation paramount to pseudoscience. [1] Debate chimers include: Andrew McIntosh (2009), Emory Bunn (2009), and Granville Sewell (2013), among others. |
Entropy change per organism: -3x10E-30 J/K (per second)
Entropy change of biosphere: -302 J/K (per second)
“Presumably the entropy of the earth’s biosphere is indeed decreasing by a tiny amount [ΔSbiosphere = -302 J/K∙s] due to evolution, and the entropy of the cosmic microwave background is increasing by an even greater amount to compensate for that decrease.”
“Styer’s factor of 1000 was not really generous, that in fact organisms should be considered to be, on average, about 10E25 times more improbable each century, but went on to show that, still, “the second law of thermodynamics is safe.”
“This is then compared to the total entropy received by the earth from a rate of solar radiation estimated to be absorbed by the earth for a given period of time. However, all these authors are making the same assumption – viz. that all one needs is sufficient energy flow into a closed system (or open system, where mass flow is allowed) and this will be the means of increasing the probability of life developing in complexity and new machinery evolving. But as stated earlier this begs the question of how a local system can possibly reduce the entropy without existing machinery to do this?”
| American physicist Daniel Styer's general assertion, which is behind the Roemer-Styer fiasco, namely that the entropy of an evolving organism can be calculated, via Boltzmann entropy, and this does not violate the second law, but rather concurs with it via the local entropy decrease model. |
“Performing calculations to show evolution does not violate the second law of thermodynamics implies that natural selection explains the complexity of living organisms. The second law of thermodynamics is an absolute truth. It is like saying the chance of getting heads when you flip a coin is 50%. When a tree grows from a seed by absorbing oxygen and carbon dioxide there is no violation of this law. However, the idea of calculating the entropy of the tree and heat flows into the plant to prove this strikes me as being absurd. I may be wrong, but this is how I understood the article.”— David Roemer (2012), “Letter to David Jackson, Editor of AJP” (Ѻ), Feb 1
“Two American Journal of Physics articles are promoting misinformation. According to the second law of thermodynamics, an isolated system of non-interacting particles will either be in equilibrium or go to a state of greater disorder. In other words, nature goes from the more complex state of speed and location to the less complex state. The two articles report scientific calculations showing that evolution does not violate the second law of thermodynamics. Laymen interpret this to mean that natural selection explains the complexity of life.”— David Roemer (2012), “Evolution and the Second Law of Thermodynamics” (Ѻ), Article submitted to AJP (but rejected), Feb 24
“Much of the confusion in applying the second law to evolution, and to other situations where entropy is difficult to define and quantify, comes from the idea that “entropy” is a single quantity which measures (in units of thermal entropy) disorder of all types. The American Journal of Physics papers by Daniel Styer (2008) and Emory Bunn (2009) illustrate the confusion that results from thinking of entropy as a single quantity when applying the second law to evolution.”
“Styer estimated the rate of decrease in entropy associated with biological evolution as less than 302 joules/degree kelvin/second, noted that this rate is very small, and concluded, “Presumably the entropy of the Earth’s biosphere is indeed decreasing by a tiny amount due to evolution and the entropy of the cosmic microwave background is increasing by an even greater amount to compensate for that decrease”. To arrive at this estimate, Styer assumed that “each individual organism is 1000 times more improbable than the corresponding individual was 100 years ago,” which, according to Styer, is a “very generous” assumption. He then used the Boltzmann formula to calculate that a 1000-fold decrease in probability corresponds to an entropy decrease of kB × log(1000), multiplied this by a generous overestimate for the number of organisms on earth, and divided by the number of seconds in a century.”
“In December 2013 I had an exchange with a man named David Roemer, who stated that he was the same as the CreationWiki “article”. When I pointed out the facts outlined above, he could find no fault with them. Yet he persisted in denigrating my work, not through any scientific fault, but because he claimed it was “atheistic propaganda”.”
“According to Psalm 19, ‘the heavens proclaim the glory of god’. And indeed they do. The heavens proclaim a magnificent universe, 13.798±0.037 billion years old, full of microwave radiation, galaxies, clusters, stars, nebulae, and planets (1078 known to date); various and arresting and beautiful. At least one planet has life: 1.2 million cataloged species — far too many to have been discovered and named by one individual— varying from zebras to Sequoia to whales to gnats to Hallucigenia to Bdellovibrio to Sulfolobus. But even without life our planet is various and arresting and beautiful: crystals, lodestones, fluid turbulence, waterfalls, geysers, rainbows, clouds; 79 million cataloged chemical compounds, combinations of 92 naturally occurring elements, all made up of electrons, protons, and neutrons. Every day new scientific discoveries show that the glory we know at present is but a fraction of the full glory of god.”
“My paper uses the microcanonical expression for entropy S = kB ln W , but ‘this is absurd because the Boltzmann constant [kB] comes from observations about atomic systems.’ In fact, living things are made up of atoms, so the microcanonical expression for entropy is perfectly reasonable and applicable. The suggestion that the Boltzmann constant applies only to “atomic systems” is also false. For example, black body radiation is not made up of atoms, yet the entropy of black body radiation of volume V and temperature T involves Boltzmann’s constant through:
where c represents the speed of light and h represents Planck’s constant.”
