Four Laws That Drive the Universe

The laws of thermodynamics drive everything that happens in the universe. From the sudden expansion of a cloud of gas to the cooling of hot metal, and from the unfurling of a leaf to the course of life itself, everything is moved or restrained by four simple laws. They establish fundamental concepts such as temperature and heat, and reveal the arrow of time and even the nature of energy itself.

Written by Peter Atkins, one of the worlds leading authorities on thermodynamics, this powerful and compact introduction explains what these four laws are and how they work, using accessible language and virtually no mathematics. Guiding the reader a step at a time, Atkins begins with Zeroth (so named because the first two laws were well established before scientists realized that a third law, relating to temperature, should precede them, hence the jocular name zeroth), and proceeds through the First, Second, and Third Laws, offering a clear account of concepts such as the availability of work and theconservation of energy.

Atkins ranges from the fascinating theory of entropy (revealing how its unstoppable rise constitutes the engine of the universe), through the concept of free energy, and to the brink, and then beyond the brink, of absolute zero.

C.P. Snow once remarked that not knowing the second law of thermodynamics is like never having read a work by Shakespeare. This brief but brilliant book introduces general readers to one of the cornerstones of modern science, four laws that are as integral to the well-educated mind as such great dramatic works as Hamlet or Macbeth.

These are not the same ones learned in kindergarten. Indeed Atkins (chemistry, U. of Oxford) warns that they will exercise the mind in ways that leave it perhaps sore but more lithe than before. The four laws concern thermodynamics: temperature, energy, entropy, and how absolute zero is like Eden. Annotation ©2007 Book News, Inc., Portland, OR (booknews.com)

The laws of thermodynamics drive everything that happens in the universe. From the sudden expansion of a cloud of gas to the cooling of hot metal, and from the unfurling of a leaf to the course of life itself - everything is directed and constrained by four simple laws. Peter Atkins' powerful and compelling introduction explains what the laws are and how they work.

Peter Atkins is Professor of Chemistry at the University of Oxford and Fellow of Lincoln College. He is the author of nearly 60 books, which include Galileo's finger: The Ten Great Ideas of Science and the famed textbook Physical Chemistry (now in its eighth edition).

Prologue

1. THE ZEROTH LAW: the concept of temperature

2. THE FIRST LAW: the conservation of energy

3. THE SECOND LAW: the increase in entropy

4. FREE ENERGY: the availability of work

5. THE THIRD LAW: the unattainability of zero
