An interdisciplinary team of researchers has proposed nothing less than a new law of #nature, according to which the #complexity of entities in the #universe increases over time with an inexorability comparable to the second law of #thermodynamics — the law that dictates an inevitable rise in entropy, a measure of disorder.

If they’re right, complex and intelligent #life should be widespread.

#Zoomposium with Prof. Dr. #Arieh #Ben-#Naim: “Demystifying #Entropy”

Information about the person and his scientific work

In another installment of our “Zoomposium series” on the topic of #physics and its #limits, my colleague Axel Stöcker from the “Blog der großen Fragen” and I had the opportunity to interview the renowned Israeli physical chemist Prof. Dr. Arieh Ben-Naim on the exciting topic of “Demystifying Entropy”.

Arieh, who was born on July 11, 1934, held a chair in #Physical #Chemistry at the Hebrew University of Jerusalem for over 40 years, with his main field of research being the theory of the #structure of #water, aqueous solutions and hydrophobic-hydrophilic interactions. He was mainly concerned with theoretical and experimental aspects of the general theory of #liquids and #solutions. In recent years, he has advocated the use of #information theory to better understand and advance #statistical #mechanics and #thermodynamics.

In this context, he has also worked intensively on the question of the nature and underlying principle of the phenomenon of #entropy, which he has published in numerous often cited but also controversially discussed popular science books.

The basic tenor of all his publications and lectures is that we need a new basic understanding of the phenomenon of entropy. In Arieh's view, entropy, which originally stems from the laws of #thermodynamics and in particular the 2nd law, has been misused and incorrectly transferred as a #concept to other areas of #physics, #biology and everyday #life.

In this respect, it was finally time (bon mot) to ask the author himself about his ground-breaking theses, which cast a different light on the #phenomenon of entropy or perhaps better said, bring entropy back to its place of origin.

The interview we conducted with him is in English.

"This work connects the dots among the great pillars of twentieth century #physics #thermodynamics, #relativity, and #quantummechanics—for a major paradigm shift…implications of quantum information processing in wetware at ambient temperatures," said Kurian.

"Physicists and cosmologists should wrestle with these findings, especially as they consider the origins of life on Earth and elsewhere in the habitable universe, evolving in concert with the electromagnetic field."

phys.orgPhysicist revisits the computational limits of life and Schrödinger's essential question in the era of quantum computingMore than 80 years ago, Erwin Schrödinger, a theoretical physicist steeped in the philosophy of Schopenhauer and the Upanishads, delivered a series of public lectures at Trinity College, Dublin, which eventually came to be published in 1944 under the title "What is Life?"

Can cells break the laws of thermodynamics?
Our preprint investigates the current scientific controversy. Using our nanosensor, we addressed unexpected artifacts and measured temperature with record accuracy inside cells.

The remarkable work from P. Maurer's lab also independently reports similar artifacts.

This may well be the most indecipherable #English sentence in the history of #physics. Gibbs once wrote:
Again, when such gases have been mixed, there is no more impossibility of the separation of the two kinds of molecules in virtue of their ordinary motions in the gaseous mass without any especial external influence, than there is of the separation of a homogeneous gas into the same two parts into which it has once been divided, after these have once been mixed.
