With 30,000 known species, you could acquire a different orchid every day for eighty years and still not grow them all. Back in the realm of reality, readers of this beautiful book can quickly and easily find the orchids that are right for them -- which ones will thrive on a windowsill, which prefer artificial lights, and which need a greenhouse; which are for beginners, which for experts. And you can pinpoint the species within a particular genus that are the best ones to start with. Once you select your orchid, William Cullina's authoritative guide explains what to do to keep it alive and healthy. Featuring more than two hundred color photographs, Understanding Orchids covers everything you need to know to grow orchids successfully, whatever your level of interest or experience. With improved tissue-culture techniques making orchids more affordable, and the Internet making them readily available to consumers, growing orchids is more popular than ever: membership in the American Orchid Society has more than doubled in the last fifteen years. This is the book orchid fans have been waiting for.

    Will our species change radically? Or will we become builders of the next dominant intelligence on Earth- the machine?These and other seemingly fantastic scenarios are the very possible realities explored in Peter Ward's Future Evolution, a penetrating look at what might come next in the history of the planet. Looking to the past for clues about the future, Ward describes how the main catalyst for evolutionary change has historically been mass extinction. While many scientist direly predict that humanity will eventually create such a situation, Ward argues that one is already well underway--the extinction of large mammals--and that a new Age of Humanity is coming that will radically revise the diversity of life on Earth. Finally, Ward examines the question of human extinction and reaches the startling conclusion that the likeliest scenario is not our imminent demise but long term survival--perhaps reaching as far as the death of the Sun!Full of Alexis Rockman's breathtaking color images of what animals, plants and other organisms might look like thousands and millions of years from now, Future Evolution takes readers on an incredible journey through time from the deep past into the far future.

    This book reveals how anyone can begin to visualize the enigmatic 'imaginary numbers' that first baffled mathematicians in the 16th century.

    Pretl offers crafters her original method for creating decorative beaded boxes and lids in a wide range of surface designs and shapes. Working only with cylinder and seed beads, needle and thread, crafters can create an impressive array of clever and colorful miniature containers. With step-by-step illustrations and easy-to-follow word graphs and patterns, Pretl leads the reader through the techniques for creating three-sided, five-sided, and six-sided rectangular, square, and stacked boxes. Four-color photographs of each of the 12 designs introduce each set of instructions. Detailed drawings illustrate the beading techniques.

    The skills of the average sock knitter are increased through design exploration and advanced stitch manipulation, treating the sock as a knitted canvas where elements are strategically and intentionally placed. New designs of floral lace patterns, angular geometric shapes, and unusual cables are presented along with detailed instructions on modifications to suit needs and aesthetics. The incredible range of style and complexity in this guide runs from sweet and simple to delightfully imaginative.

    Montezuma Strip: First world tech and Third World wages, sprawling from L.A. to East Elpaso Juarez, Guyamas to Phoenix; a thousand gangs, a million locos; and a few wealthy beyond the dreams of god.

    Take a fun journey through the history of science as it transforms from a field of wild speculation into a powerful tool of understanding. Explore the world in upheaval as Earth changed from center of the universe to a smallish planet orbiting an average star. Find out about hidden races and unknown creatures (like Yetis); early and bizarre thoughts on evolution; ancient astronauts and UFO crazes; the music of the spheres; the acquisition of virtues through cannibalism, and much more!

    Packed with math activities and puzzles, compelling stories of math geniuses, math facts and stats, and more, How to be a Math Genius makes the dreaded subject of math both engaging and relevant.

    Genes are important, but only as part of a process constrained by environment, physical laws, and the universal tendencies of complex adaptive systems. In a new preface for this edition, Goodwin reflects on the advances in both genetics and the sciences of complexity since the book's original publication.

    It covers all relevant areas, including molecular spectroscopy, electronic structure computations, molecular beam methods and time-resolved measurements of chemical systems.

    After the Limited Test Ban Treaty between the United States and the Soviet Union in 1963, nuclear testing went underground. It became literally invisible—but more frequent: the United States conducted a further 723 underground tests, the last in 1992. 100 Suns documents the era of visible nuclear testing, the atmospheric era, with one hundred photographs drawn by Michael Light from the archives at Los Alamos National Laboratory and the U.S. National Archives in Maryland. It includes previously classified material from the clandestine Lookout Mountain Air Force Station based in Hollywood, whose film directors, cameramen and still photographers were sworn to secrecy.The title, 100 Suns, refers to the response by J.Robert Oppenheimer to the world’s first nuclear explosion in New Mexico when he quoted a passage from the Bhagavad Gita, the classic Vedic text: “If the radiance of a thousand suns were to burst forth at once in the sky, that would be like the splendor of the Mighty One . . . I am become Death, the destroyer of worlds.” This was Oppenheimer’s attempt to describe the otherwise indescribable. 100 Suns likewise confronts the indescribable by presenting without embellishment the stark evidence of the tests at the moment of detonation. Since the tests were conducted either in Nevada or the Pacific the book is simply divided between the desert and the ocean. Each photograph is presented with the name of the test, its explosive yield in kilotons or megatons, the date and the location. The enormity of the events recorded is contrasted with the understated neutrality of bare data. Interspersed within the sequence of explosions are pictures of the awestruck witnesses. The evidence of these photographs is terrifying in its implication while at same time profoundly disconcerting as a spectacle. The visual grandeur of such imagery is balanced by the chilling facts provided at the end of the book in the detailed captions, a chronology of the development of nuclear weaponry and an extensive bibliography. A dramatic sequel to Michael Light’s Full Moon, 100 Suns forms an unprecedented historical document.

    Sacred Geometry offers an accessible way of understanding how that connection is revealed in nature and the arts. Over the centuries, temple builders have relied on magic numbers to shape sacred spaces, astronomers have used geometry to calculate holy seasons, and philosophers have observed the harmony of the universe in the numerical properties of music. By showing how the discoveries of mathematics are manifested over and over again in biology and physics, and how they have inspired the greatest works of art, this illuminating study reveals the universal principles that link us to the infinite.

    The remaining lectures build on that idea, examining the possibility of building a relativistic quantum theory on curved surfaces or flat surfaces.
