The Failures of Mathematical Anti-Evolutionism (Jason Rosenhouse) (z-lib.org)
(Sewell 2013a, 168)
He later elaborates: [T]he whole idea of compensation, whether by distant or nearby events, makes no sense logically: an extremely improbable event is not rendered less improbable simply by the occurrence of “compensating” events elsewhere. According to this reasoning, the second law does not prevent scrap metal from reorganizing itself into a computer in one room, as long as two computers in the next room are rusting into scrap metal – and the door is open. (Sewell 2013a, 170) Sewell often uses hypotheticals like this to mock the idea that entropy decreases in one part of a system can be compensated for by increases elsewhere. Here is another example: 256 7 thermodynamics I was discussing the second law argument with a friend recently, and mentioned that the second law has been called the “common sense law of physics.” The next morning he wrote: Yesterday I spoke with my wife about these questions. She immediately grasped that chaos results in the long term if she would stop caring for her home. I replied: Tell your wife she has made a perfectly valid application of the second law of thermodynamics. In fact, let’s take her application a bit further. Suppose you and your wife go for a vacation, leaving a dog, a cat, and a parakeet loose in the house (I put the animals there to cause the entropy to increase more rapidly, otherwise you might have to take a much longer vacation to see the same effect). When you come back, you will not be surprised to see chaos in the house. But tell her some scientists say, “but if you leave the door open while on vacation, your house becomes an open system, and the second law does not apply to open systems … you may find everything in better condition than when you left.” I’ll bet she will say, “If a maid enters through the door and cleans the house, maybe, but if all that enters is sunlight, wind and other animals, probably not.” (Sewell 2013a, 175–176, ellipsis in original) Keep in mind that this quotation appeared in what was intended to be a scholarly article, as opposed to an article directed towards lay audiences. It was published as part of the proceedings of the academic conference on biological information I mentioned in Section 6.3. I take that to mean that Sewell, as well as the team of editors who assembled the proceedings volume, are happy to have this considered as a prime example of ID scholarship. We will come to Sewell’s discussion of the “compensation” argument momentarily, but first we must consider some of the sillier 7.10 reviving the second law argument 257 aspects of his writing, if only to appreciate, once again, why scientists become very impatient when responding to ID folks. In light of our previous discussion, Sewell’s remarks are readily seen to have no connection to reality. No one has ever claimed that “anything can happen” in an open system. The actual claim is that the second law is a precise mathematical statement. If your proposed physical process does not violate equation 7.2, then it is not ruled out by the second law. There might be reasons having nothing to do with thermodynamics for thinking the process is impossible, but you are, at least, good to go as far as the second law is concerned. Chemist Bob Lloyd, in a response to Sewell, expressed the point well: [W]e should note that the phrase “anything can happen” is highly tendentious. If one shows that a particular process is not forbidden by the Second Law, that falls far short of showing that it can happen. Download 0.99 Mb. Do'stlaringiz bilan baham: |
