FAYETTEVILLE, Ark. – A team of University of Arkansas physicists has successfully developed a circuit capable of capturing graphene's thermal motion and converting it into an electrical current. “An energy-harvesting circuit based on graphene could be incorporated into a chip to provide clean, limitless, low-voltage power for small devices or sensors,” said Paul Thibado, professor of physics and lead researcher in the discovery.The findings, titled "Fluctuation-induced current from freestanding graphene," and published in the journal Physical Review E, are proof of a theory the physicists developed at the U of A three years ago that freestanding graphene — a single...

A Second Look at the Second Law Granville Sewell Mathematics Dept. Texas A&M University Can ANYTHING Happen in an Open System? In the current debate over "Intelligent Design," the strongest argument offered by opponents of design is this: we have scientific explanations for most everything else in Nature, what is special about evolution? The layman understands quite well that explaining the appearance of human brains is a very different sort of problem from finding the causes of earthquakes; however, to express this difference in terms a scientist can understand requires a discussion of the second law of thermodynamics. The first...

Autocatakinetics, Evolution, and the Law of Maximum Entropy Production By Rod Swenson An Excerpt: Ecological science addresses the relations of living things to their environments, and the study of human ecology the particular case of humans. There is an opposing tradition built into the foundations of modern science of separating living things, and, in particular, humans from their environments. Beginning with Descartes’ dualistic world view, this tradition found its way into biology by way of Kant, and evolutionary theory through Darwin, and manifests itself in two main postulates of incommensurability, the incommensurability between psychology and physics (the “first postulate of...
