From the sudden expansion of a cloud of gas to the cooling of hot metal--everything is moved or restrained by four simple laws. Written by Peter Atkins, one of the world's 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. About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics. Written by experts for the newcomer, they demonstrate the finest contemporary thinking about the central problems and issues in hundreds of key topics, from philosophy to Freud, quantum theory to Islam.

    Cartledge highlights the role of such renowned cities as Athens (birthplace of democracy) and Sparta, but he also examines Argos, Thebes, Syracuse in Sicily, and Alexandria in Egypt, as well as lesser known locales such as Miletus (home of the West's first intellectual, Thales) and Massalia (Marseilles today), where the Greeks introduced the wine grape to the French. The author uses these cities to illuminate major themes, from economics, religion, and social relations, to gender and sexuality, slavery and freedom, and politics.

    Paul Slack assesses its causes, which have often been disputed and are now being illuminated by microbiologists and archaeologists, and he looks at possible reasons for its periodic disappearance from whole continents. He shows what plague meant for those who suffered from it, and how governments began to fight against it and in doing so invented modern notions of public health. His focus throughout the book is on how people coped with death and disease in epidemic crises.
