Free Download Strange Attractors: Poems of Love and Mathematics By Sarah Glaz, Joanne Growney
2008 | 250 Pages | ISBN: 1568813414 | PDF | 4 MB
Strange Attractors is a collection of approximately 150 poems with strong links to mathematics in content, form, or imagery. The common theme is love, and the editors draw from its various manifestations-romantic love, spiritual love, humorous love, love between parents and children, mathematicians in love, love of mathematics. The poets include literary masters as well as celebrated mathematicians and scientists. "What, after all, is mathematics but the poetry of the mind, and what is poetry but the mathematics of the heart?" So wrote the American mathematician and educator David Eugene Smith. In a similar vein, the German mathematician Karl Weierstrass declared, "A mathematician who is not at the same time something of a poet will never be a full mathematician." Most mathematicians will know what they meant. But what do professional poets think of mathematics? In this delightful collection, the editors present the view of the same terrain-the connections between mathematics and poetry-from the other side of the equation: the poets. Now is your chance to see if the equation balances. -Keith Devlin, mathematician, Stanford University, and author of The Math Gene, The Math Instinct, and The Language of Mathematics

Free Download David K. Hecht, "Storytelling and Science: Rewriting Oppenheimer in the Nuclear Age "
English | ISBN: 1625341423 | 2015 | 208 pages | EPUB | 615 KB
No single figure embodies Cold War science more than the renowned physicist J. Robert Oppenheimer. Although other scientists may have been more influential in establishing the institutions and policies of the nuclear age, none has loomed larger in the popular imagination than the "father of the atomic bomb." Americans have been drawn to the story of the Manhattan Project Oppenheimer helped lead and riveted by the McCarthy-era politics that caught him in its crosshairs. Journalists and politicians, writers and artists have told Oppenheimer's story in many different ways since he first gained notoriety in 1945. In Storytelling and Science, David K. Hecht examines why they did so, and what they hoped to achieve through their stories.

Free Download Storm Kings: The Untold History of America's First Tornado Chasers By Lee Sandlin
2013 | 304 Pages | ISBN: 0307378527 | EPUB | 6 MB
With 16 pages of black-and-white illustrationsFrom the acclaimed author of Wicked River comes Storm Kings, a riveting tale of supercell tornadoes and the quirky, pioneering, weather-obsessed scientists whose discoveries created the science of modern meteorology.While tornadoes have occasionally been spotted elsewhere, only the central plains of North America have the perfect conditions for their creation. For the early settlers the sight of a funnel cloud was an unearthly event. They called it the "Storm King," and their descriptions bordered on the supernatural: it glowed green or red, it whistled or moaned or sang. In Storm Kings, Lee Sandlin explores America's fascination with and unique relationship to tornadoes. From Ben Franklin's early experiments to the "great storm war" of the nineteenth century to heartland life in the early twentieth century, Sandlin re-creates with vivid descriptions some of the most devastating storms in America's history, including the Tri-state Tornado of 1925 and the Peshtigo "fire tornado," whose deadly path of destruction was left encased in glass.Drawing on memoirs, letters, eyewitness testimonies, and archives, Sandlin brings to life the forgotten characters and scientists who changed a nation-including James Espy, America's first meteorologist, and Colonel John Park Finley, who helped place a network of weather "spotters" across the country. Along the way, Sandlin details the little-known but fascinating history of the National Weather Service, paints a vivid picture of the early Midwest, and shows how successive generations came to understand, and finally coexist with, the spiraling menace that could erase lives and whole towns in an instant.

Free Download Maria Teresa Brolis, "Stories of Women in the Middle Ages Ed 3"
English | ISBN: 0773554793 | 2018 | 208 pages | AZW3 | 345 KB
Between the twelfth and fifteenth centuries in Europe, not all women fit the stereotype of passive housewife and mother. Many led bold and dynamic lives. In this collection of historical portraits, Maria Teresa Brolis tells the fascinating tales of fashion icons, art clients, businesswomen, saints, healers, lovers, and pilgrims - both famous and little known - who challenge conventional understandings of the medieval female experience. Drawing on evidence from literary works and archival documents that include letters, chronicles, trials, testimonials, notary registers, contracts, and wills, Brolis pieces together an intricate overview of sixteen women's lives. With zest and compassion, she describes the mysterious visionary Hildegard of Bingen, the cultured Heloisa, the powerful Eleanor of Aquitaine, Saint Clare of Assisi, the rebel Joan of Arc, as well as lesser-known women such as Flora, the penitent moneylender, Bettina the healer, and Belfiore the pilgrim, among others. Following the trajectories and divergences of their lives from wealth to poverty, from conjugal love to the love of community, from the bedroom to life on the streets of Paris, London, Mainz, Rome, and Bergamo, each portrait offers a riveting glimpse into the often complex and surprising world of the medieval woman. Combining the rigour of research with the thrill and empathy of narrative, Stories of Women in the Middle Ages is a provocative investigation into the biographies of sixteen incredible medieval heroines.

Brings the Crusades to life through stories of its most famous participants. Relates how Peter the Hermit, with the Pope's blessing, gathers men to his side and leads the first crusade, resulting in the capture of Jerusalem and installation of Godfrey as defender of the holy sepulchre. After the Muslims recapture Jerusalem, three great kings of Europe vow to regain the Holy City: King Richard the Lionhearted of England, King Philip of France, and the Emperor Frederick of Germany. Despite winning many battles in this third crusade and capturing the city of Acre, they fail to win back the city of Jerusalem. King Louis of France launches the last crusade, but dies before achieving his objective. Throughout the narrative we meet all sorts of men. Some, like Bohemond and Baldwin, fight for selfish ends; others, such as Tancred and Louis, do battle like the great knights they are; while a few, Francis among them, carry goodwill wherever they go.
