The Second Law (Scientific American Library) First Edition
Simply stated, the Second Law recognizes the intrinsic asymmetry in nature. Aspects of this asymmetry can be found all around us: hot objects cool, but cool objects do not spontaneously become hot; a bouncing ball comes to rest, but a stationary ball does not spontaneously begin to bounce. Oxford professor P. W. Atkins begins his examination of these seemingly random but vitally important phenomena with early observations of the steam engine and traces the deepening understanding that emerged when the atomic basis of the Law was established. He analyzes the Law from a modern viewpoint, enabling us to see how a single, simple idea encompasses all elements of natural change.
Atkins explores this idea from its first recognition through its application in engines, refrigerators, and heat pumps to its role as the driving force of chemical reactions and, finally, to the emergence of the exquisitely ordered structures characteristic of life itself.
Using striking computer graphics to develop a unified picture of nature, the author shows us how structures are built apparently out of chaos until we grasp the underlying, awesome simplicity of complexity. An appendix details how to program the generation of printouts of the concepts discussed.

About the author
Peter Atkins was born in England in 1940 and went to the University of Leicester for his first degree (in chemistry) and his PhD (1964). After a year in UCLA as a Harkness Fellow he went to Oxford University as lecturer in physical chemistry and Fellow of Lincoln College, where he remained until his retirement in 2007. Some retirement! He continues to write books, which now number close to 70 with more on the way. He was the founding chairman of IUPAC's Committee on Chemistry Education, which is charged with bringing good practice in the teaching of chemistry, especially in developing countries, and has been a visiting professor in Japan, China, Israel, France, and New Zealand. He continues to lecture widely, both on aspects of chemical education and on the communication of science to the general public. He lives near Oxford.

First, the Universe in not a “temporary” structure. And there was no great network before the Big Bang when such a structure would emerge from chaos. No chaos existed. Nor is the Universe at an equilibrium point. Atkins writing on Payle’s watch says, “Paley’s famous watch summarizes the argument for an active designer: If I found a watch, he argued, the intricacy of the mechanism would leave me in no doubt that It had been designed, that there had once, at least, been a designer. He went on to argue that the natural world has an even greater intricacy of the construction, and that a traveler coming across the world would be left in no doubt that it too had been designed, and that there had once, at least, been a Designer.” (pg. 189)
But there is more to Paley’s argument. Paley’s watch may be represented by an 1860 Hamilton pocket watch, a marvel of compressed engineering. Some of those watches were fitted with crystal backs, such that the marvelous mechanism was visible. Of course, the universe is not a Hamilton watch. But what the watch and the universe have in common, is complexity and high order. In fact, the universe exhibits far greater complexity and order than does a Hamilton watch. It is this complexity and order that we can legitimately compare. Now in Paley’s watch, we may make the analogy (following the comparison of complexity and order) that the main spring might symbolize the Second Law. Then the First Law of Thermodynamic might symbolize one of the pivots. The classical laws of physics, say, the law of motion in response to a force will be represented. The laws of Special Relativity would be represented by some of the parts. The four forces would be represented. Time and space would be represented. Then, all the material that makes up this world, including the microparticles like protons and electrons would be represented. All the wave particles such as photons, neutrinos, and others would be found there. The point is, a Hamilton pocket watch operates by precise coordination of its operating parts, just as does the Universe, but with far more precision that does a Hamilton watch. All of the Laws of Physics function perfectively smoothly with the same objective purpose. In the case of the Hamilton watch its to tell time. In the case of the universe its to exist and function as it does. Note that William Paley never claimed that life or, for example the complex human eye, can be explained by presuming a designer. Life in the Darwinian scenario, was the result of a long process of natural selection, while things like protons, electrons, and the physical laws, all working together, need a designer explanation. Near the end of the book Atkins makes a telling statement, which brought back the fifth star: ‘The Second Law is a global denial of the emergence of spontaneous structure.” IE, The Second Law rules out “chance” as a cause of the birth of the universe.
But exactly what is entropy? How can it be understood in term of intuitive concepts? What is the relation between the enginner's entropy and the microscopic one (the disorder index)? Why is it so fundamental, yet so arcane that no one ever dared explain it except to teach us how to compute it?
P.W. Atkins answers these questions beautifully. First, he makes an historical account of how we became aware of the concept and defines it from a contemporary perpective. He very accurately and clearly dissect the fundamentals of the laws of thermodynamics. He then gives us numerous examples of how entropy is relevant to the understanding of nature's process, be it in physics, mechanics, chemistry or biology, etc. Eventually, one acquires an intuitive understanding of why these two laws are so fundamentals: why these are so important and prevalent? Why their existence is so unavoidable?
In order to undertand this book,no special mathematical knowledge is required. The logic is rigorous yet affordable and the text is very well structured. You may find the task easier if you have at least a college degree in science but all that is really required is the discipline to pay attention.
At the end of the book, you will appreciate the orderly fashion of the authors toughts. Most of all you will enjoy the very visceral pleasure of seeing one more part of nature's beauty.

Un excellent livre à propos de l'entropie, qui permet - sans équations ou presque - de changer sa vision de la thermodynamique... Et donc du monde ? Attention il existe une édition plus récente.
