Homer called salt a divine substance. Plato described it as especially dear to the gods. Today we take salt for granted, a common, inexpensive substance that seasons food or clears ice from roads, a word used casually in expressions ("salt of the earth," take it with a grain of salt") without appreciating their deeper meaning. However, as Mark Kurlansky so brilliantly relates in his world- encompassing new book, salt―the only rock we eat―has shaped civilization from the very beginning. Its story is a glittering, often surprising part of the history of mankind.Until about 100 years ago, when modern chemistry and geology revealed how prevalent it is, salt was one of the most sought-after commodities, and no wonder, for without it humans and animals could not live. Salt has often been considered so valuable that it served as currency, and it is still exchanged as such in places today. Demand for salt established the earliest trade routes, across unknown oceans and the remotest of deserts: the city of Jericho was founded almost 10,000 years ago as a salt trading center. Because of its worth, salt has provoked and financed some wars, and been a strategic element in others, such as the American Revolution and the Civil War. Salt taxes secured empires across Europe and Asia and have also inspired revolution (Gandhi's salt march in 1930 began the overthrow of British rule in India); indeed, salt has been central to the age-old debate about the rights of government to tax and control economies. The story of salt encompasses fields as disparate as engineering, religion, and food, all of which Kurlansky richly explores. Few endeavors have inspired more ingenuity than salt making, from the natural gas furnaces of ancient China to the drilling techniques that led to the age of petroleum, and salt revenues have funded some of the greatest public works in history, including the Erie Canal, and even cities (Syracuse, New York). Salt's ability to preserve and to sustain life has made it a metaphorical symbol in all religions. Just as significantly, salt has shaped the history of foods like cheese, sauerkraut, olives, and more, and Kurlansky, an award-winning food writer, conveys how they have in turn molded civilization and eating habits the world over. Salt is veined with colorful characters, from Li Bing, the Chinese bureaucrat who built the world's first dam in 250 BC, to Pattillo Higgins and Anthony Lucas who, ignoring the advice of geologists, drilled an east Texas salt dome in 1901 and discovered an oil reserve so large it gave birth to the age of petroleum. From the sinking salt towns of Cheshire in England to the celebrated salt mine on Avery Island in Louisiana; from the remotest islands in the Caribbean where roads are made of salt to rural Sichaun province, where the last home-made soya sauce is made, Mark Kurlansky has produced a kaleidoscope of history, a multi-layered masterpiece that blends economic, scientific, political, religious, and culinary records into a rich and memorable tale.

Anyone alive in the eighteenth century would have known that "the longitude problem" was the thorniest scientific dilemma of the day―and had been for centuries. Lacking the ability to measure their longitude, sailors throughout the great ages of exploration had been literally lost at sea as soon as they lost sight of land. Thousands of lives, and the increasing fortunes of nations, hung on a resolution.The scientific establishment of Europe―from Galileo to Sir Isaac Newton―had mapped the heavens in both hemispheres in its certain pursuit of a celestial answer. In stark contrast, one man, John Harrison, dared to imagine a mechanical solution―a clock that would keep precise time at sea, something no clock had ever been able to do on land. Longitude is the dramatic human story of an epic scientific quest, and of Harrison's forty-year obsession with building his perfect timekeeper, known today as the chronometer. Full of heroism and chicanery, it is also a fascinating brief history of astronomy, navigation, and clockmaking, and opens a new window on our world.

David Wade has spent a lifetime gathering and organizing the extraordinary families of surface patterns that nature throws up at every scale. The study of these shapes―a subject virtually unknown in the West―was known in ancient China as Li and is the sister science to Feng Shui. In this unique and insightful book are sand and wave patterns, big-cat markings, bark and leaf designs, soap and marbling swirls, crystalline and rock forms, tree branching types, and many more of nature's dynamic, sometimes enigmatic designs. Li will appeal to scientists and artists, and has far-reaching applications in graphic design, architecture, and other visual forms and sciences.
