Sure, it's even simpler than it was before. Of course, you don't have to worry about fertilizer or poor soil ever again because you'll be growing above the ground. However, the best feature is that anyone, anywhere can enjoy a square foot garden - children, adults with limited mobility, and even complete novices can achieve spectacular results. But, let's get back to the ten improvements. You're going to love them: 1. New Location - Move your garden closer to your house by eliminating single-row gardening. Square foot gardens need just 20% of the space of a traditional garden.2. New Direction - Locate your garden on top of existing soil. Forget about pH soil tests, double-digging (who enjoys that?), or those never-ending soil improvements.3. New Soil - The new "Mel's Mix" is the perfect growing mix. We give you the recipe, and best of all, you can even buy the different types of compost needed.4. New Depth - You only need to prepare a SFG box to a depth of 6 inches! It's true - the majority of plants develop just fine when grown at this depth.5. No Fertilizer - The all new SFG does not need any fertilizer - ever! If you start with the perfect soil mix, then you don't need to add fertilizer.6. New Boxes - The new method uses bottomless boxes placed above ground. We show you how to build your own (with step-by-step photos).7. New Aisles - The ideal gardening aisle width is about three to four feet. That makes it even easier to kneel, work, and harvest.8. New Grids - Prominent and permanent grids added to your SFG box help you visualize your planting squares and properly space them for maximum harvest.9. New Seed-Saving Idea - The old-fashioned way advocates planting many seeds and then thinning the extras (that means pulling them up). The new method means planting a pinch - literally two or three seeds - per planting hole.10. Tabletop Gardens - The new boxes are so much smaller and lighter (only 6 inches of soil, remember?), you can add a plywood bottom to make them portable. Of course, that's not all. We've also included simple, easy-to-follow instructions using lots of photos and illustrations. You're going to love it!

    Starting with Ptolemy, "father of modern geography," and ending with satellite cartography, A History of the World in 12 Maps brings maps from classical Greece, Renaissance Europe, and the Islamic and Buddhist worlds to life and reveals their influence on how we—literally—look at our present world. As Brotton shows, the long road to our present geographical reality was rife with controversy, manipulation, and special interests trumping science. Through the centuries maps have been wielded to promote any number of imperial, religious, and economic agendas, and have represented the idiosyncratic and uneasy fusion of science and subjectivity. Brotton also conjures the worlds that produced these notable works of cartography and tells the stories of those who created, used, and misused them for their own ends.

    And watch out for One Finger Jimmy, Chainsaw Charlie and their gangster friends, who are living proof that maths can be murderous.

    Hellstrom's Project 40 was a cover for a secret laboratory, a special team of agents was immediately dispatched to discover its true purpose and its weaknesses—it could not be allowed to continue. What they discovered was a nightmare more horrific and hideous than even their paranoid government minds could devise.First published in Galaxy magazine in 1973 as "Project 40," Frank Herbert's vivid imagination and brilliant view of nature and ecology have never been more evident than in this classic of science fiction.

    Now William Dunham gives them the attention they deserve.Dunham places each theorem within its historical context and explores the very human and often turbulent life of the creator — from Archimedes, the absentminded theoretician whose absorption in his work often precluded eating or bathing, to Gerolamo Cardano, the sixteenth-century mathematician whose accomplishments flourished despite a bizarre array of misadventures, to the paranoid genius of modern times, Georg Cantor. He also provides step-by-step proofs for the theorems, each easily accessible to readers with no more than a knowledge of high school mathematics.A rare combination of the historical, biographical, and mathematical, Journey Through Genius is a fascinating introduction to a neglected field of human creativity.

    He found that by tracing the placement of fossils, which he uncovered in his excavations, one could follow layers of rocks as they dipped and rose and fell -- clear across England and, indeed, clear across the world -- making it possible, for the first time ever, to draw a chart of the hidden underside of the earth. Determined to expose what he realized was the landscape's secret fourth dimension, Smith spent twenty-two years piecing together the fragments of this unseen universe to create an epochal and remarkably beautiful hand-painted map. But instead of receiving accolades and honors, he ended up in debtors' prison, the victim of plagiarism, and virtually homeless for ten years more. Finally, in 1831, this quiet genius -- now known as the father of modern geology -- received the Geological Society of London's highest award and King William IV offered him a lifetime pension.The Map That Changed the World is a very human tale of endurance and achievement, of one man's dedication in the face of ruin. With a keen eye and thoughtful detail, Simon Winchester unfolds the poignant sacrifice behind this world-changing discovery.

    He discloses the amazing opportunities that 3D Printing will bring, the magic of hoverboards, solemnly shares why dark matter matters, and spills the scientific basis of wealth distribution.Thereby Science is decreed to be the only true ruler of the kingdom, and there is none better to claim the Throne than Australia's most trusted and knowledge-thirsty scientist - Dr Karl.

    His famous book, The Travels of Marco Polo, indicates that he was a man of extraordinary bravery, brilliance, and strength. With his uncle and father, he traveled across Turkey, Armenia, the Middle East, the rugged mountains of Afghanistan, and the hot Taklimakan Desert before finally reaching China in 1275. Welcomed by the great emperor Kublai Khan, Marco Polo was amazed by the inventions, riches, and religious tolerance of the great Khan’s kingdom, where Marco remained for the next 2 years.

    In Physics of the Impossible, the renowned physicist Michio Kaku explores to what extent the technologies and devices of science fiction that are deemed equally impossible today might well become commonplace in the future.From teleportation to telekinesis, Kaku uses the world of science fiction to explore the fundamentals—and the limits—of the laws of physics as we know them today. He ranks the impossible technologies by categories—Class I, II, and III, depending on when they might be achieved, within the next century, millennia, or perhaps never. In a compelling and thought-provoking narrative, he explains:· How the science of optics and electromagnetism may one day enable us to bend light around an object, like a stream flowing around a boulder, making the object invisible to observers “downstream”· How ramjet rockets, laser sails, antimatter engines, and nanorockets may one day take us to the nearby stars· How telepathy and psychokinesis, once considered pseudoscience, may one day be possible using advances in MRI, computers, superconductivity, and nanotechnology· Why a time machine is apparently consistent with the known laws of quantum physics, although it would take an unbelievably advanced civilization to actually build oneKaku uses his discussion of each technology as a jumping-off point to explain the science behind it. An extraordinary scientific adventure, Physics of the Impossible takes readers on an unforgettable, mesmerizing journey into the world of science that both enlightens and entertains.

    This frustration led to Foster's first book, George Washington's World (1941). In her unique approach, Foster weaves a story of the world around her central character; rather than focusing exclusively on geo-political events, as most textbooks do; she includes stories of scientific discovery and invention, music, literature, art, and religion. She has a keen intuition for stories that will especially delight and amuse her youthful audience. In Augustus Caesar's World, Foster traces the seven major civilizations Rome, Greece, Israel, Egypt, China, India, and Persia from 4500 B.C. to the time of Augustus Caesar in 44 B.C. and culminating in 14 A.D. Within this timeframe readers will learn not only the stories of Julius Caesar, Cleopatra, and Marc Antony, but also the historian Livy and how Virgil came to write the Aeneid. Foster will then take her readers all over the world to learn what was happening at this same time in China, Persia, India and so on. Foster's detailed pen and ink drawings are fresh and appealing, and her illustrated timelines give a clear sense of chronology, enriching the engaging text. An all-time customer favorite!
