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 the conservation 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....

Why Galileo's finger? Galileo, one of whose fingers is preserved in a vessel displayed in Florence, provided much of the impetus for modern science, pointing the way out of medieval ignorance. In this brilliant account of the central ideas of contemporary science, Peter Atkins celebrates the effectiveness of Galileo's symbolic finger for revealing the nature of our universe, our world, and ourselves. Galileo's Finger takes the reader on an extraordinary journey that embraces the ten central ideas of current science. 'By a great idea,' writes Peter Atkins, 'I mean a simple concept of great reach, an acorn of an idea that ramifies into a great oak tree of application, a spider of an idea that can spin a great web and draw in a feast of explanation and elucidation.' With wit, charm, and patience, Atkins leads the reader to an understanding of the essence of the whole of science, from evolution and the emergence of complexity, to entropy, the spring of all change in the universe; from energy, the universalization of accountancy, to symmetry, the quantification of beauty; and from cosmology, the globalization of reality, to spacetime, the arena of all action. 'My intention is for us to travel to the high ridges of science,' Atkins tells us. 'As the journey progresses and I lead you carefully to the summit of understanding, you will experience the deep joy of illumination that science alone provides.' Galileo's Finger breaks new ground in communicating science to the general reader. Here are the essential ideas of today's science, explained in magical prose....
