Paperback. Etat : Very Good. London, 1923. Newly minted research assistant Saffron Everleigh is the first woman to hold the position at University College of London. When she attends a dinner party for the school, she expects to engage in conversations about the university's large expedition to the Amazon. What she doesn't expect is for Mrs. Henry, one of the professors' wives, to drop to the floor, poisoned by an unknown toxin. Dr. Maxwell, Saffron's mentor, is the main suspect, and evidence quickly mounts. Joined by flirtatious fellow researcher Alexander Ashton, Saffron uses her knowledge of botany as she explores steamy greenhouses, dark gardens, and deadly poisons to clear Maxwell's name. Will she be able to uncover the truth, or will her investigation land her on the murderer's list? In this entertaining examination of society's expectations, debut author Kate Khavari deftly sheds a light on the struggles of women in a male-dominated field, wrapped in mystery and murder.…

Hardback. Etat : Fair. Soon to be a Netflix film William Kamkwamba was born in Malawi, a country where magic ruled and modern science was mystery. It was also a land withered by drought and hunger. But William had read about windmills, and he dreamed of building one that would bring to his small village a set of luxuries that only 2 percent of Malawians could enjoy: electricity and running water. His neighbors called him misala--crazy--but William refused to let go of his dreams. With a small pile of once-forgotten science textbooks; some scrap metal, tractor parts, and bicycle halves; and an armory of curiosity and determination, he embarked on a daring plan to forge an unlikely contraption and small miracle that would change the lives around him. The Boy Who Harnessed the Wind is a remarkable true story about human inventiveness and its power to overcome crippling adversity. It will inspire anyone who doubts the power of one individual's ability to change his community and better the lives of those around him.…

Hardback. Etat : Good. If, in the ancient world, it was guns and germs and steel that determined the fates of people and nations, in modern times it is electricity. No other form of power translates into affluence and influence like it. Though demand for it is growing exponentially, it remains one of the most difficult forms of energy to supply and to do so reliably. Storage is even harder. This paradox has shaped global politics, affected the outcome of wars, and underlies the growing chasm between rich and poor, educated and uneducated. It is changing the game for business, and the requirements of national defence. It is altering the landscape and complicating the task of dealing effectively with climate change. In this book, Robert Bryce explains the unique nature of electricity as a commodity. He draws on stories from history to illustrate the stunning impact of our quest to harness it, illuminates exactly what is required to successfully sustain it, and explores the impact on societies and individuals when it collapses. As billions of people around the world still live in darkness, the gap between the electricity haves and have-nots widens, with profound political and ethical consequences. Modern life, even civilisation, has become ever more dependent on a source of energy that must be produced locally and in the moment, in a reliably steady stream at particular wattage, conveyed on wires strung on poles or threaded through pipes. If the lights go out, so does our manner of living, with potentially devastating consequences.…

Hardback. Etat : Very Good. Nikola Tesla was an eccentric genius who out-Edisoned Edison and out Marconied Marconi. Born of modest means in what is now Croatia and later becoming a naturalized American citizen, Tesla's inventions include the alternating current (AC) that powers our homes today, radio, wireless transmission, X-rays, and the electrifying Tesla coil. He even worked on development of direct energy weapons (death rays) and vertical takeoff and landing (VTOL) aircraft. During his lifetime Tesla moved first to Paris, then to New York, and after a period of time in Colorado Springs back to New York City where he maintained two laboratories. Along the way he worked for Edison, then became his biggest rival, and formed friendships with such divergent personalities as George Westinghouse, Mark Twain, a pigeon, all while reflecting on a childhood cat. His idiosyncrasies included an obsession with numbers divisible by three, ardent gambling, and a near-pathological fear of germs. He rarely slept more than a few hours at a time, often going days without rest. While generally soft-spoken, he could be a consummate showman, often insisting that his Tesla coil be present while he lectured, seemingly shooting lightning bolts as he spoke. In the end he died alone and nearly penniless, having ceded perhaps billions of dollars in royalties to his friend George Westinghouse. This illustrated book takes us through Tesla's life, his experiments and contributions to science, and brings us into his complex mind. Through ample use of his writings and interviews with the societies and inventors clubs that honor his name, we explore Tesla's methods and discoveries, personality quirks, and his legacy for the modern world - both scientific and popular culture. …

Paperback. Etat : Fair. The bestselling author of E=mc2 weaves tales of romance, divine inspiration, and fraud through an account of the invisible force that permeates our universe--electricity--and introduces us to the virtuoso scientists who plumbed its secrets. For centuries, electricity was seen as little more than a curious property of certain substances that sparked when rubbed. Then, in the 1790s, Alessandro Volta began the scientific investigation that ignited an explosion of knowledge and invention. The force that once seemed inconsequential was revealed to be responsible for everything from the structure of the atom to the functioning of our brains. In harnessing its power, we have created a world of wonders--complete with roller coasters and radar, computer networks and psychopharmaceuticals. In Electric Universe, the great discoverers come to life in all their brilliance and idiosyncrasy, including the visionary Michael Faraday, who struggled against the prejudices of the British class system, and Samuel Morse, a painter who, before inventing the telegraph, ran for mayor of New York City on a platform of persecuting Catholics. Here too is Alan Turing, whose dream of a marvelous thinking machine--what we know as the computer--was met with indifference, and who ended his life in despair after British authorities forced him to undergo experimental treatments to "cure" his homosexuality. From the frigid waters of the Atlantic to the streets of Hamburg during a World War II firestorm to the interior of the human body, Electric Universe is a mesmerizing journey of discovery. …
