Amazon.com Review
Length and mass are measurements we understand intuitively, but temperature is fleeting and elusive. Why is it so hard to measure compared with other fundamentals? Why do living things require such a narrow range of temperatures to go about their business? How cold is deep space, anyway? Physicist Gino Segre knows how to keep interest flowing along; even when he's explaining the intricacies of small-scale physics, he takes time to ground it in real life. His scope is wide--from the beginning (and ending) of the universe to the history of life on Earth, little falls outside his purview. Yet the book touches on so many subjects of immediate interest to 21st-century humans (high fevers, sports medicine, and the next scheduled Ice Age, to name a few) that it's compelling even to those who don't care about the Big Questions.

From Publishers Weekly
Segre, a theoretical physicist at the University of Pennsylvania, begins this far-ranging survey of the history of science by explaining how living organisms maintain stable temperatures and showing how adaptations to hot or cold habitats influenced animal evolution. Subsequent chapters cover a wide range of topics such as the development of heat-measuring technologies; influences of temperature on earth's climate, including speculations on "snowball" and "slushball" earth scenarios and the greenhouse effect; survival mechanisms of thermophiles and psychrophiles (bacteria that tolerate extremely high and extremely low temperatures, respectively); and the role of neutrinos, tiny particles produced in the core of the sun, in explaining solar dynamics. Segre observes that the history of human civilization can be read as a story of the "ever-hotter fires humans made as they moved from hunter-gatherers to villagers to toolmakers," while the formation of the universe can be seen as a vast cooling, from one hundred billion degrees at one hundredth of a second after the big bang to the cooler temperatures at which neutrons and protons could bind together (one billion degrees) and some 300,000 years later hydrogen and helium atoms could form (3,000 degrees). While some of Segre's material will be a challenge to readers without knowledge of college-level physics, he brings humor and passion to his subject and excels in showing its relevance to both current policy and future research.
