The result is a work that is nothing short of magnificent.” —Wired When renowned British geneticist J. B. S. Haldane was asked what could be inferred about God from a study of his works, Haldane replied, “An inordinate fondness for beetles.” With 350,000 known species, and scientific estimates that millions more have yet to be identified, their abundance is indisputable as is their variety. They range from the delightful summer firefly to the one-hundred-gram Goliath beetle. Beetles offer a dazzling array of shapes, sizes, and colors that entice scientists and collectors across the globe. The Book of Beetles celebrates the beauty and diversity of this marvelous insect. Six hundred significant beetle species are covered, with each entry featuring a distribution map, basic biology, conservation status, and information on cultural and economic significance. Full-color photos show the beetles both at their actual size and enlarged to show details, such as the sextet of spots that distinguish the six-spotted tiger beetle or the jagged ridges of the giant-jawed sawyer beetle. Based in the most up-to-date science and accessibly written, the descriptive text will appeal to researchers and armchair coleopterists alike. The humble beetle continues to grow in popularity, taking center stage in biodiversity studies, sustainable agriculture programs, and even the dining rooms of adventurous and eco-conscious chefs. The Book of Beetles is certain to become the authoritative reference on these remarkably adaptable and beautiful creatures. “Photographs of more than 600 colorful, glossy species, resembling bejeweled broaches morethan creepy crawlies, are presented at actual size.” —Publishers Weekly

Book Synopsis The History of Speed by : Martin Roach
Download or read book The History of Speed written by Martin Roach and published by Simon and Schuster. This book was released on 2020-10-29 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'A special treat...The pictures and stories combine to provide a rich texture to telling the difficult story of why we chase speed like an addiction.' Valerie Thompson, the world's fastest female motorcycle racer Ever since we built machines that could transport us, there has been a desire to find ways to make them go faster. For some, going faster isn't enough - they want to be the fastest. This book celebrates those who have built the machines and driven them at ever greater speeds. This is The History of Speed. Bestselling motorsport writer Martin Roach tells the extraordinary story of those who have come to be obsessed by speed. From Camille Jenatzy, 'the Red Devil', who became the first man to drive at over 100kmh in 1899, through the golden age of Malcolm Campbell and his Bluebird, and on to the modern era of jet- and rocket-propelled cars, we have gone faster and faster. But this book is not just about these record-breakers, Roach also looks at the technology, the engines and the inventors who helped progress in speed at all levels, from Formula One to the supercars from the likes of Ferrari and Mercedes that are eagerly snapped up by collectors, rarely to be seen on the road. Accompanied by some of the most stunning images of the cars and those who made and drove them, Roach tells a wonderful story of innovation and invention. He talks to some of the great drivers to find out what inspires them to risk their lives, and finds out from engineers how they developed their ideas. Along the way, we hear some remarkable tale and anecdotes, but also find out how the pursuit of speed can also have its costs, with many tragic heroes and heroines falling along the way. If you've ever thrilled to the roar of a sports car engine, of loved the feel of the g-force as you accelerate away, or even looked on in wonder at a powerful engine, The History of Speed is a book that you will not want to miss out on.
