The lens he invented was a brilliant feat of engineering that made lighthouses blaze many times brighter, farther, and more efficiently. Battling the establishment, his own poor health, and the limited technology of the time, Fresnel was able to achieve his goal of illuminating the entire French coast. At first, the British sought to outdo the new Fresnel-equipped lighthouses as a matter of national pride. Americans, too, resisted abandoning their primitive lamps, but the superiority of the Fresnel lens could not be denied for long. Soon, from Dunkirk to Saigon, shores were brightened with it.  The Fresnel legacy played an important role in geopolitical events, including the American Civil War. No sooner were Fresnel lenses finally installed along U.S. shores than they were drafted: the Union blockaded the Confederate coast; the Confederacy set about thwarting it by dismantling and hiding or destroying the powerful new lights.Levitt’s scientific and historical account, rich in anecdote and personality, brings to life the fascinating untold story of Augustin Fresnel and his powerful invention.

    The Simple Guide to® Freshwater Aquariums concentrates on providing you with a complete plan and all the information you need to choose and use the right-for-you aquarium equipment and the right-for-you fish and plants: it wants you to succeed. The information is presented in a completely straightforward text that's easy to read, easy to understand - and very definitely easy to put to good use.

    It offers the best information in the world on the current popular and traditional uses of the nearly 500 species covered, much of it available for the first time. More than 530 color photographs illustrate the plants and their flowers, leaves, and fruits. The descriptive text combines scientific, ethnobotanical, and cross-cultural information, making this field guide unique. An index to medical topics is helpful for quickly locating information on specific ailments. Symbols next to the plant descriptions provide quick visual warnings for poisonous and allergenic plants. Organized by flower color for fast identification, this guide is an essential aid to appreciating native plants and the wild areas they inhabit.

     This field guide features detailed descriptions of 455 species of trees native to eastern North America, including the Midwest and the South. The 48 color plates, 11 black-and-white plates, and 26 text drawings show distinctive details needed for identification. Color photographs and 266 color range maps accompany the species descriptions.

    Amateur and expert alike can quickly and accurately identify almost any wildflower using Lawrence Newcomb's system, which is based on natural structural features that are easily visible even to the untrained eye. Every time you see an unknown plant, ask yourself the same five questions (related to the type of plant and the structure of its petals and leaves), and you will be directed to the page on which the plant can be found. Beautiful illustrations make confirmation easy.

    Yet in backyards and on rooftops all over the world, bees are being raised successfully, even without antibiotics, miticides, or other chemical inputs.More and more organically minded beekeepers are now using top-bar hives, in which the shape of the interior resembles a hollow log. Long lasting and completely biodegradable, a topbar hive made of untreated wood allows bees to build comb naturally rather than simply filling prefabricated foundation frames in a typical box hive with added supers.Top-bar hives yield slightly less honey but produce more beeswax than a typical Langstroth box hive. Regular hive inspection and the removal of old combs helps to keep bees healthier and naturally disease-free.Top-Bar Beekeeping provides complete information on hive management and other aspects of using these innovative hives. All home and hobbyist beekeepers who have the time and interest in keeping bees intensively should consider the natural, low-stress methods outlined in this book. It will also appeal to home orchardists, gardeners, and permaculture practitioners who look to bees for pollination as well as honey or beeswax.

    A best-selling, fully illustrated, and comprehensive book, this large-format volume has been required reading for every angler for the past two decades.

An outstanding feature is the 160-page "Encyclopedia of Edibles"—a book in itself—which alphabetically lists more than 120 edible species, with detailed horticultural information, landscaping and culinary uses, seed sources, and recipes. Other valuable features include an abundance of how-to illustrations, photographs, and landscape diagrams designed for beginners and experts alike, plus a list of mail-order nurseries, a climate zone map, and extensive appendices.

    Presented in A-to-Z format, supplemented with easy-to-use charts and lists, beautifully illustrated with drawings and color photographs, it is the only book on herbs you ever need to buy.

    In Unruly Places, Alastair Bonnett goes to some of the most unexpected, offbeat places in the world to reinspire our geographical imagination.Bonnett’s remarkable tour includes moving villages, secret cities, no man’s lands, and floating islands. He explores places as disorienting as Sandy Island, an island included on maps until just two years ago despite the fact that it never existed. Or Sealand, an abandoned gun platform off the English coast that a British citizen claimed as his own sovereign nation, issuing passports and crowning his wife as a princess. Or Baarle, a patchwork of Dutch and Flemish enclaves where walking from the grocery store’s produce section to the meat counter can involve crossing national borders.An intrepid guide down the road much less traveled, Bonnett reveals that the most extraordinary places on earth might be hidden in plain sight, just around the corner from your apartment or underfoot on a wooded path. Perfect for urban explorers, wilderness ramblers, and armchair travelers struck by wanderlust, Unruly Places will change the way you see the places you inhabit.

    David Holmgren brings into sharper focus the powerful and still evolving Permaculture concept he pioneered with Bill Mollison in the 1970s. It draws together and integrates 25 years of thinking and teaching to reveal a whole new way of understanding and action behind a simple set of design principles. The 12 design principles are each represented by a positive action statement, an icon and a traditional proverb or two that captures the essence of each principle.Holmgren draws a correlation between every aspect of how we organize our lives, communities and landscapes and our ability to creatively adapt to the ecological realities that shape human destiny. For students and teachers of Permaculture this book provides something more fundamental and distilled than Mollison's encyclopedic "Designers Manual." For the general reader it provides refreshing perspectives on a range of environmental issues and shows how permaculture is much more than just a system of gardening. For anyone seriously interested in understanding the foundations of sustainable design and culture, this book is essential reading. Although a book of ideas, the big picture is repeatedly grounded by reference to Holmgren's own place, Melliodora, and other practical examples.
