The history of the development of Euclidean, non-Euclidean, and relativistic ideas of the shape of the universe, is presented in this lively account by Jeremy Gray. The parallel postulate of Euclidean geometry occupies a unique position in the history of mathematics. In this book, Jeremy Gray reviews the failure of classical attempts to prove the postulate and then proceeds to show how the work of Gauss, Lobachevskii, and Bolyai, laid the foundations ofmodern differential geometry, by constructing geometries in which the parallel postulate fails. These investigations in turn enabled the formulation of Einstein's theories of special and general relativity, which today form the basis of our conception of the universe. The author has made every attempt to keep the pre-requisites to a bare minimum. This immensely readable account, contains historical and mathematical material which make it suitable for undergraduate students in the history of science and mathematics. For the second edition, the author has taken the opportunity to update much of the material, and to add a chapter on the emerging story of the Arabic contribution to this fascinating aspect of the history of mathematics.

INSTANT NEW YORK TIMES BESTSELLER “Most appealing... technical accuracy and lightness of tone... Impeccable.”—Wall Street Journal “A porthole into another world.”—Scientific American “Brings science dissemination to a new level.”—Science The most trusted explainer of the most mind-boggling concepts pulls back the veil of mystery that has too long cloaked the most valuable building blocks of modern science. Sean Carroll, with his genius for making complex notions entertaining, presents in his uniquely lucid voice the fundamental ideas informing the modern physics of reality. Physics offers deep insights into the workings of the universe but those insights come in the form of equations that often look like gobbledygook. Sean Carroll shows that they are really like meaningful poems that can help us fly over sierras to discover a miraculous multidimensional landscape alive with radiant giants, warped space-time, and bewilderingly powerful forces. High school calculus is itself a centuries-old marvel as worthy of our gaze as the Mona Lisa. And it may come as a surprise the extent to which all our most cutting-edge ideas about black holes are built on the math calculus enables. No one else could so smoothly guide readers toward grasping the very equation Einstein used to describe his theory of general relativity. In the tradition of the legendary Richard Feynman lectures presented sixty years ago, this book is an inspiring, dazzling introduction to a way of seeing that will resonate across cultural and generational boundaries for many years to come.

Anyone interested in science, sibling relationships, and friendships will enjoy reading We Dream of Space.”—Time for Kids Newbery Medalist and New York Times–bestselling author Erin Entrada Kelly transports readers to 1986 and introduces them to the unforgettable Cash, Fitch, and Bird Nelson Thomas in this pitch-perfect middle grade novel about family, friendship, science, and exploration. This acclaimed Newbery Honor Book is a great choice for readers of Kate DiCamillo, Rita Williams-Garcia, and Rebecca Stead. Cash, Fitch, and Bird Nelson Thomas are three siblings in seventh grade together in Park, Delaware. In 1986, as the country waits expectantly for the launch of the space shuttle Challenger, they each struggle with their own personal anxieties. Cash, who loves basketball but has a newly broken wrist, is in danger of failing seventh grade for the second time. Fitch spends every afternoon playing Major Havoc at the arcade on Main and wrestles with an explosive temper that he doesn’t understand. And Bird, his twelve-year-old twin, dreams of being NASA’s first female shuttle commander, but feels like she’s disappearing. The Nelson Thomas children exist in their own orbits, circling a tense and unpredictable household, with little in common except an enthusiastic science teacher named Ms. Salonga. As the launch of the Challenger approaches, Ms. Salonga gives her students a project—they are separated into spacecraft crews and must create and complete a mission. When the fated day finally arrives, it changes all of their lives and brings them together in unexpected ways. Told in three alternating points of view, We Dream of Space is an unforgettable and thematically rich novel for middle grade readers. We Dream of Space is illustrated throughout by the author.

The radical history of space exploration from the Russian Cosmists to Elon Musk Many societies have imagined going to live in space. What they want to do once they get up there - whether conquering the unknown, establishing space "colonies," privatising the moon's resources - reveals more than expected. In this fascinating radical history of space exploration, Fred Scharmen shows that often science and fiction have combined in the imagined dreams of life in outer space, but these visions have real implications for life back on earth. For the Russian Cosmists of the 1890s space was a place to pursue human perfection away from the Earth. For others, such as Wernher Von Braun, it was an engineering task that combined, in the Space Race, the Cold War, and during World War II, with destructive geopolitics. Arthur C. Clark in his speculative books offered an alternative vision of wonder that is indifferent to human interaction. Meanwhile NASA planned and managed the space station like an earthbound corporation. Today, the market has arrived into outer space and exploration is the plaything of superrich technology billionaires, who plan to privatise the mineral wealth for themselves. Are other worlds really possible? Bringing these figures and ideas together reveals a completely different story of our relationship with outer space, as well as the dangers of our current direction of extractive capitalism and colonisation.
