TLDR
If such a statistical distribution of entropy were possible in the biological world, a similar statistical distribution should also exist in non-living systems; and for every spontaneous reaction, a small number of products with decreased entropy should result.
Abstract
IT has been suggested that a statistical distribution of entropy among a large number of entities will lead to a small percentage of them possessing a lower entropy than the mean value for the group as a whole1. To illustrate this point Campbell considered the example of the codfish laying a million eggs. This, however, is not a representative example of the entire biological world, for birds and mammals produce a very small number of eggs and the higher mammals produce only one egg at a time. Furthermore, if such a statistical distribution of entropy were possible in the biological world, a similar statistical distribution should also exist in non-living systems; and for every spontaneous reaction, a small number of products with decreased entropy should result. This is contrary to all known facts.

INformation, entropy and various systems.

TL;DR: This paper considers the theoretical example of the information required in the synthesis of complex linear polymers, and the information manifested by such compounds once formed, by distinguishing three categories: structural, functional, and bound information.

Time in Statistical Physics and Special Relativity

TL;DR: The effort to meet the Society's request for a talk on this topic has been a humbling experience as discussed by the authors, and it is difficult for all concerned if, instead, I present a point of view.

The effects from combining urea and an alcohol on the heat-induced reversible denaturation of ribonuclease.

TL;DR: The presence of urea decreases the hydrophobic effect of a monovalent alcohol, strongly at low temperatures, to a lesser degree at high temperatures (60 degrees C), and hinders the interhydrophobic interactions by affecting the water molecules.

Aspects of the Clausius-Shannon identity: emphasis on the components of transitive information in linear, branched and composite physical systems.

TL;DR: The relationship between information and entropy, known as the Clausius-Shannon Identity, is discussed with reference to selected thermodynamic models and that aspect of information which is often overlooked, namely the distinction, between transitive and intransitive information is highlighted.

Entropy and evolution.

TL;DR: The author merely evades one of the most important questions at issue in the earlier correspondence when he says that those eggs which are “most likely to grow and repeat the reproductive process” are those whose genomes have a lower entropy content than those of the parents.

Does Quantum Mechanics exclude Life

TL;DR: In this paper, a discussion of self-reproduction is discussed from the point of view of quantum mechanics in connexion with living objects. But it can only be very speculative (as pointed out in our publications), since a living system is always large by quantum mechanical standards.

Time's Arrow and Feeding on Negentropy

TL;DR: In the article "Time's Arrow and Entropy" as mentioned in this paper, only one voice of dissent, Professor Buchel's letter, has been expressed, and this letter consists of three paragraphs, to which I shall reply in order.

Biological Entropy Pump

TL;DR: The “entropy pump” is described whereby the species of living matter not only prevent a drop into a position of greater positive entropy at each generation, but may in fact acquire more negentropy as their reproduction continues.

Does Quantum Mechanics exclude Life

TL;DR: In this paper, the possibility that quantum mechanics might predict and explain the phenomena of life was discussed and discussed in a recent paper by LANDSBERG, who reopened a problem discussed earlier by Wigner.
