A fascinating compendium of the metals, rocks, organic materials, and gems that have had the greatest impact on the development of human civilisation from prehistory to the present day. Using the word 'minerals' in its broadest sense, FIFTY MINERALS THAT CHANGED THE COURSE OF HISTORY features the metals, alloys, rocks, organic minerals, and gemstones that humans have used as the building blocks of their material cultures. From flint and obsidian to bronze and iron, it explores the roots of industry and trade from the earliest recorded history, and marvels at the extraordinary works of art produced in gold, silver, ivory and jade by the great classical civilisations of the Old and New Worlds. Moving to modern times, it charts the industrialisation of societies through the use of fossil fuels, the production of steel and aluminium and the harnessing of nuclear energy from uranium and plutonium. FIFTY MINERALS THAT CHANGED THE COURSE OF HISTORY is a beautifully presented guide to the minerals that have shaped and defined our lives. Weaving together strands of economic, cultural, political and industrial history, each entry gives a fascinating perspective on the scope and pace of human development, and the dangers posed by our exploitation of Earth's resources.

Everybody needs a rock -- at least that's the way this particular rock hound feels about it in presenting her own highly individualistic rules for finding just the right rock for you.

The fascinating stories of the animals that changed civilizations.

From the award-winning and bestselling author of Cod comes the dramatic, human story of a simple substance, an element almost as vital as water, that has created fortunes, provoked revolutions, directed economies and enlivened our recipes. Salt is common, easy to obtain and inexpensive. It is the stuff of kitchens and cooking. Yet trade routes were established, alliances built and empires secured – all for something that filled the oceans, bubbled up from springs, formed crusts in lake beds, and thickly veined a large part of the Earth’s rock fairly close to the surface. From pre-history until just a century ago – when the mysteries of salt were revealed by modern chemistry and geology – no one knew that salt was virtually everywhere. Accordingly, it was one of the most sought-after commodities in human history. Even today, salt is a major industry. Canada, Kurlansky tells us, is the world’s sixth largest salt producer, with salt works in Ontario playing a major role in satisfying the Americans’ insatiable demand. As he did in his highly acclaimed Cod, Mark Kurlansky once again illuminates the big picture by focusing on one seemingly modest detail. In the process, the world is revealed as never before.

The Pulitzer Prize-winning view of the continent, across the fortieth parallel and down through 4.6 billion years Twenty years ago, when John McPhee began his journeys back and forth across the United States, he planned to describe a cross section of North America at about the fortieth parallel and, in the process, come to an understanding not only of the science but of the style of the geologists he traveled with. The structure of the book never changed, but its breadth caused him to complete it in stages, under the overall title Annals of the Former World. Like the terrain it covers, Annals of the Former World tells a multilayered tale, and the reader may choose one of many paths through it. As clearly and succinctly written as it is profoundly informed, this is our finest popular survey of geology and a masterpiece of modern nonfiction. Annals of the Former World is the winner of the 1999 Pulitzer Prize for Nonfiction.
