The scandals, mysteries, and human stories behind the world’s greatest gems are brought to life by the curator of the Smithsonian’s National Gem Collection Dr. Jeffrey E. Post, curator of the National Gem Collection for more than 25 years, separates fact from fiction in an all-new and original book, revealing fresh information and regaling the reader with anecdotes and tales of some of the world’s greatest and most famous gemstones. Dr. Post is the author of the now out-of-print book The National Gem Collection (Abrams, 1997), which has sold more than 50,000 copies. In this brand-new book, he tells the stories of the Smithsonian’s most famous gems, including the Hope Diamond, Star of Asia Sapphire, Carmen Lucia Ruby, Hooker Emerald, and Blue Heart Diamond—and also presents the tales, details, and fascinating facts surrounding rarely displayed gems from the Smithsonian vault and additions made to the collection since 1997. Not only a resource for learning about rare and beautiful gems, the book also presents the stories of the people who once owned or were associated with these jewels—from ordinary people to kings, emperors, maharajas, celebrities, and captains of industry.

How a simple equation reshaped mathematics Leonhard Euler’s polyhedron formula describes the structure of many objects—from soccer balls and gemstones to Buckminster Fuller’s buildings and giant all-carbon molecules. Yet Euler’s theorem is so simple it can be explained to a child. From ancient Greek geometry to today’s cutting-edge research, Euler’s Gem celebrates the discovery of Euler’s beloved polyhedron formula and its far-reaching impact on topology, the study of shapes. Using wonderful examples and numerous illustrations, David Richeson presents this mathematical idea’s many elegant and unexpected applications, such as showing why there is always some windless spot on earth, how to measure the acreage of a tree farm by counting trees, and how many crayons are needed to color any map. Filled with a who’s who of brilliant mathematicians who questioned, refined, and contributed to a remarkable theorem’s development, Euler’s Gem will fascinate every mathematics enthusiast. This paperback edition contains a new preface by the author.
