Negentropy (decreasing entropy): the Beginning of Life according to the laws of Physics.

Abstract

The “physical” point of view, regarding the beginning of life, is explained just referring to very simple concepts like Heat, Work, Energy, Irreversibility and Entropy: this is done, of course, without using any mathematical formula, but merely discussing things in a plain, simple language.

Basically, when a sperm and an ovum merge, a silent (but dramatic) change takes place: by means of such a lilliputian “marriage” both of them, otherwise bound to die in few hours, manage to reverse the normal, universal Entropy growth (established by the Second Principle of Thermodynamics) triggering a sort of chain reaction which turns billions of cahotic molecules into a perfectly organized body.

Additional considerations are also reported: first of all, Irreversibility is correlated to Probability and the famous issue regarding the Direction of Time; secondly, the DNA information (the Project) is shown being the only thing actually “surviving” from the initial agglomerate of atoms which the first cell was made of; finally, evaluating human growth (from conception through birth) in terms of Percent-per-Day clearly shows how the very first stage of life turns out to be the most significant of all.

As a matter of fact, even Physics (seemingly so far from Life and Death issues) can represent a clear “voice” backing who, from the mother’s womb, is not yet capable of making himself heard: it is another small contribution to the vast mosaic of opinions, considerations, and irrefutable facts that strongly support human life from the very beginning.
