Vodka! Can nuclear structure be affected by electrical, chemical, mechanical and biological means?

The answer appears to be yes (at least for electrical and mechanical means, don’t know for sure about chemical and biological means). A physics professor assigned our class term papers of our choosing. Our goal was to learn something new. I chose to explore the effects of electricity and chemistry on nuclear processes. I thought […] more

Kirk Durston: A common either-or mistake both Darwinists and ID theorists make

The question is whether natural selection has sufficient information to locate stable, functional, biological proteins. All our work to date seems to falsify that option … more

Was four-stranded, ‘quadruple helix’ DNA designed or mutated?

‘Quadruple helix’ DNA seen in human cells Balasubramanian’s group has been pursuing a four-stranded version of the molecule (DNA) that scientists have produced in the test tube now for a number of years. It is called the G-quadruplex. The “G” refers to guanine, one of the four chemical groups, or “bases”, that hold DNA together […] more

A Designed Object’s Entropy Must Increase for Its Design Complexity to Increase – Part 2

In order for a biological system to have more biological complexity, it often requires a substantial increase in thermodynamic entropy, not a reduction of it, contrary to many intuitions among creationists and IDists. This essay is part II of a series that began with Part 1 The physicist Fred Hoyle famously said: The chance that […] more

A Designed Object’s Entropy Must Increase for Its Design Complexity to Increase – Part 1

The common belief is that adding disorder to a designed object will destroy the design (like a tornado passing through a city, to paraphrase Hoyle). Now if increasing entropy implies increasing disorder, creationists will often reason that “increasing entropy of an object will tend to destroy its design”. This essay will argue mathematically that this […] more

Does the Constructal Law Give Evidence of Design?

In Bejan’s “Design in Nature”, Bejan promotes what he calls the “constructal law,” which states, “For a finite-size system to persist in time (to live), it must evolve in such a way that it provides easier access to the imposed currents that flow through it.” Bejan has denied that this relates at all to any […] more

2nd Law of Thermodynamics — an argument Creationists and ID Proponents should NOT use

ID proponents and creationists should not use the 2nd Law of Thermodynamics to support ID. Appropriate for Independence Day in the USA is my declaration of independence and disavowal of 2nd Law arguments in support of ID and creation theory. Any student of statistical mechanics and thermodynamics will likely find Granville Sewell’s argument and similar […] more

Broadband Beasts

In today’s PhysOrg highlights, we hear about how yeast cells are able to communicate with one another via biochemical means. Using mathematical means to separate “noise” from information pathways. These beasts have “broadband”! “The mathematics provides variance decomposition techniques for dynamic systems,” said Dr Bowsher. “We were able to make rigorous connections between the concept […] more

First Gene: Functional sequence complexity (FSC) found in biopolymers as well as human languages and computer code

Clearly, FSC can be found in human languages and carefully designed computer code, but the measure we propose in this paper reveals that it is also found in biopolymers. more
