In his well-known work, No Free Lunch, p. 11, ID Researcher William A Dembski has illustrated the search challenge concept in terms of an arrow hitting a target amidst a reference class of possibilities. In so doing, he reaches back to the statistical mechanical and mathematical concept of a phase space “cut down” to address […]
thermodynamics and information
A Maxwell Demon engine in action beyond the Carnot/ “standard” Second law limit
Maxwell’s Demon (sometimes, “Max”) has long been a fictional device for discussing how if we have access to information we can manipulate molecular scale particles to extract work. Now, physics dot org is discussing a case: >>Physicists have experimentally demonstrated an information engine—a device that converts information into work—with an efficiency that exceeds the conventional […]
What is “information”?
Information, of course, is notoriously a concept that has many senses of meaning. As it is central to the design inference, let us look (again) at defining it. We can dispose of one sense right off, Shannon was not directly interested in information but in information-carrying capacity; that is why his metric will peak for […]
Upright Biped’s summary on information systems in cell based life
UD participant Upright Biped (of Complexity Cafe U/D: Biosemiosis) has commented recently in the what is knowledge thread, replying to frequent objector CR by summarising key aspects of the role of information systems in observed cell based life. His remarks are well worth headlining: __________________ UB, 195: >>We can start by summarizing the core physical […]
UD Guest Post: Dr Eugen S on the second law of thermodynamics (plus . . . ) vs. “evolution”
Our Physicist and Computer Scientist from Russia — and each element of that balance is very relevant — is back, with more. MOAR, in fact. This time, he tackles the “terror-fitted depths” of thermodynamics and biosemiotics. (NB: Those needing a backgrounder may find an old UD post here and a more recent one here, helpful.) […]
BTB: Points to ponder as we look at Crick’s understanding of DNA as text, since March 19, 1953
A few days back, I headlined a clip from Crick’s letter to his son Michael, March 19, 1953: The main text is accessible here (with page scans). Sans diagrams: >>My Dear Michael, Jim Watson and I have probably made a most important discovery. We have built a model for the structure of des-oxy-ribose-nucleic-acid (read it […]
Following up Bostrom’s argument from simulation of universes . . .
That is, why inferring design on functionally specific, complex organisation and associated information, e.g.: and equally: . . . makes good sense. Now, overnight, UD’s Newsdesk posted on a Space dot com article, Is Our Universe a Fake? The article features “Philosopher Nick Bostrom, director of the Future of Humanity Institute at Oxford University.” I […]
Should ID supporters argue in terms of thermodynamics or information or [“basic . . . “] probability?
In the still active discussion thread on failure of compensation arguments, long term maverick ID (and, I think, still YEC-sympathetic) supporter SalC comments: SalC, 570: . . . I’ve argued against using information theory type arguments in defense of ID, it adds way too much confusion. Basic probability will do the job, and basic probability […]
Failure of the “compensation argument” and implausibility of evolution
Granville Sewell and Daniel Styer have a thing in common: both wrote an article with the same title “Entropy and evolution”. But they reach opposite conclusions on a fundamental question: Styer says that the evolutionist “compensation argument” (henceforth “ECA”) is ok, Sewell says it isn’t. Here I briefly explain why I fully agree with Granville. […]
Second Thoughts on the Second Law: Extending an Olive Branch
Recently on niwrad’s thread we have had a lively discussion about the 2nd Law of Thermodynamics and its potential application to the question of a materialistic abiogenesis scenario. kairosfocus has followed up with another useful post. In the present thread I provide a high level view of some of the key issues and misconceptions surrounding […]
Piotr (and KS, DNA_Jock, VS, Z et al) and “compensation” arguments vs the energy audit police . . .
It seems to be time to call in the energy audit police. Let us explain, in light of an ongoing sharp exchange on “compensating” arguments in the illusion of organising energy thread. This morning Piotr, an objector (BTW — and this is one time where expertise base is relevant — a Linguist), at 288 dismissed […]
Rube Goldberg Complexity Increase in Thermodynamically Closed Systems
A thermodynamically closed system that is far from equilibrium can increase the amount of physical design provided it is either front loaded or has an intelligent agent (like a human) within it. A simple example: A human on a large nuclear powered space ship can write software and compose music or many other designs. The […]
Thoughts on the Second Law
A couple of days ago Dr. Granville Sewell posted a video (essentially a summary of his 2013 Biocomplexity paper). Unfortunately, he left comments off (as usual), which prevents any discussion, so I wanted to start a thread in case anyone wants to discuss this issue. Let me say a couple of things and then throw […]
The famous Feynman Lectures on Physics hosted free for all by Caltech (and taking a peek at entropy . . . )
Christmas is early this year. Here are the famous Feynman Lectures on Physics (Vol II is forthcoming) hosted for free by Caltech. A useful point of reference for one and all. Just for fun, note here on on entropy, irreversibility and the rise of disorder: Where does irreversibility come from? It does not come from […]
