'No wonder that Churchill described this effort as "Britain's secret weapon," a weapon far more effective than the buzz bombs and the rockets that Wernher von Braun designed for a German victory, a weapon absolutely decisive, in the judgement of many, in winning the war for the Allies.'Peter Hilton, mathematician and codebreaker, 1923-2010, about the team at Bletchley ParkThe Story of Codebreaking begins with the hieroglyphics of Ancient Egypt and weaves its way stealthily through history to the present day, where computer code is fundamental to all of our online activities. It is a tale of ordinary people rising to the challenge of extraordinary circumstances and shows how, through a combination of intelligence, grit, hard work and (occasionally) sheer good fortune, codebreakers have often saved lives and sometimes even changed the course of history.Find out how Mary Queen of Scots smuggled cryptic messages to her accomplices when she was plotting against her cousin Elizabeth I, or discover the methods used by codebreakers during World Wars I and II, most significantly those who cracked Enigma and intercepted Japanese naval messages prior to Pearl Harbor. The sheer doggedness of those who unravelled the Enigma code is thought to have shortened World War II by almost two years.To break a code, you have to put yourself in the mind of your enemy in order to probe the strengths and weaknesses of their systems. It's a game of bluff and doublebluff. The Story of Codebreaking describes undercover operations, power struggles, secret alliances, and brilliant feats of teamwork. Those who invent codes and those who break them are remarkable, indefatigable characters. This is their story.Topics include:Ancient ciphers and the art of encodingEarly spies, subterfuge and skytalesThe making and breaking of EnigmaJapanese naval codes in World War IICold War cryptography
From the acclaimed author of Spring Wildflowers of the Northeast, a beautifully illustrated follow-up introduction to the summer-blooming wildflowers of the northeastern United States and Canada
This exquisitely illustrated volume provides an accessible, in-depth introduction to summer-blooming wildflowers of the northeastern United States and Canada. Featuring more than 700 detailed color photos and a large, beautifully designed format, the book delves into the life histories of more than thirty-five wildflowers and their relatives, from common roadside favorites, such as asters and milkweeds, to interesting, lesser-known species, including Indian pipe and ginseng. Drawing on a wealth of personal experience and the latest scientific research, and presenting it all in terms anyone can understand, acclaimed naturalist and photographer Carol Gracie invites readers to enhance their appreciation of the beauty of these wildflowers by learning not just their names or how many petals they have, but what pollinates them, how their seeds are dispersed, how they interact with other plants and animals, how Native Americans and other people have used them, and other interesting facts.
Each species is illustrated with a range of detailed color photos that not only capture its beauty but illustrate the features discussed in the text and show the plant in its environment alongside the pollinators, herbivores, or seed dispersers with which, in many cases, the wildflower has evolved. Other topics covered include the naming of wildflowers; pathogens and pests; related species in other parts of the world; and wildflowers in history, literature, and art.

Over 35,000 copies sold! As a naturalist managing the field studies program at the California Academy of Sciences, John Muir Laws noticed that novice birders often distinguish birds by color and size rather than species. This inspired him to create Sierra Birds: A Hiker's Guide, a unique book that assumes no prior birding knowledge on the part of the reader. Color-coded keys eliminate the time-consuming frustration of thumbing randomly through a guide, and a cross-index is also included for more advanced birders. All this in a format that is simply organized, lightweight, and small enough to tuck inside a pocket. A first-rate naturalist, Laws is also an accomplished artist. His illustrations are lively, colorful, and accurate, and drawn to represent species in the manner in which one generally sees them in the field.
The ultimate guide to nature drawing and journaling! A potent combination of art, science, and boundless enthusiasm, the latest art instruction book from John Muir Laws (The Laws Guide to Drawing Birds) is a how-to guide for becoming a better artist and a more attentive naturalist. In straightforward text complemented by step-by-step illustrations, dozens of exercises lead the hand and mind through creating accurate reproductions of plants and animals as well as landscapes, skies, and more. Laws provides clear, practical advice for every step of the process for artists at every level, from the basics of choosing supplies to advanced techniques. While the book’s advice will improve the skills of already accomplished artists, the emphasis on seeing, learning, and feeling will make this book valuable—even revelatory—to anyone interested in the natural world, no matter how rudimentary their artistic abilities.
