Paperback. Zustand: Very Good. You will be able to watch a capable scientist work to uncover the mystery of what he suspects is a new kind of radiation, a radiation he eventually calls x-rays. A German scientist, Wilhelm Conrad Roentgen, is the main character in this book. His experimental expertise was the key element in his successful science career. When he saw something unusual as he pursued one of his experiments, he investigated to learn more. Long before Roentgen discovered x-rays many other scientists around the world had seen unusual effects, including fogging of film or electrical changes, effects that they never followed up and that later proved to have resulted from x-rays. So many scientists had the opportunity to discover x-rays. Roentgen was the only one who persisted. He learned much about these new rays, and, even though he had some misgivings about his conclusions about a new kind of rays, accepted the challenge to inform fellow scientists about his discovery. His discovery was the start of many new ideas that changed the world perception of science - and changed the lives of Roentgen and his wife Bertha. Roentgen's story is inspiring and unusual, in that he had to overcome many obstacles on his long journey to become a recognized scientist and teacher. Even after he had earned his doctorate in physics his unusual education path to an advanced degree presented problems. He persisted; his story may inspire the reader not to give up in the pursuit of a goal.…

Paperback. Zustand: Fair. Modern is a word much used, but hard to pin down. In Inventing Modern, John H. Lienhard uses that word to capture the furious rush of newness in the first half of 20th-century America. An unexpected world emerges from under the more familiar Modern. Beyond the airplanes, radios, art deco, skyscrapers, Fritz Lang's Metropolis, Buck Rogers, the culture of the open road--Burma Shave, Kerouac, and White Castles--lie driving forces that set this account of Modern apart. One force, says Lienhard, was a new concept of boyhood--the risk-taking, hands-on savage inventor. Driven by an admiration of recklessness, America developed its technological empire with stunning speed. Bringing the airplane to fruition in so short a time, for example, were people such as Katherine Stinson, Lincoln Beachey, Amelia Earhart, and Charles Lindbergh. The rediscovery of mystery powerfully drove Modern as well. X-Rays, quantum mechanics, and relativity theory had followed electricity and radium. Here we read how, with reality seemingly altered, hope seemed limitless. Lienhard blends these forces with his childhood in the brave new world. The result is perceptive, engaging, and filled with surprise. Whether he talks about Alexander Calder (an engineer whose sculptures were exercises in materials science) or that wacky paean to flight, Flying Down to Rio, unexpected detail emerges from every tile of this large mosaic. Inventing Modern is a personal book that displays, rather than defines, an age that ended before most of us were born. It is an engineer's homage to a time before the bomb and our terrible loss of confidence--a time that might yet rise again out of its own postmodern ashes. …

Hardback. Zustand: Good. Invisible light is everywhere. As you read this you are being swarmed by microwaves from your cell phone. Step outside and you'll get a dose of ultraviolet and infrared from the sun. Go on vacation and you submit to a full body security scan at the airport. Cell towers, tanning salons, microwave ovens, CT scans, mammogram machines, saunas, nuclear power plants - all are emitting radiation in your general direction. What effect is it having? An accessible blend of narrative history and science, INVISIBLE LIGHT tells the story of the unseen energies all around us, tracing infrared, microwaves, ultraviolet, X-rays and other forms of radiation from their historic discoveries and oft-misguided early uses to their health costs (and benefits) in our daily lives. With a unique talent for making science relatable and fun, Bob Berman hunts for leftover light rays from the universe's birth, explores the consequences of our newest technologies, looks at how invisible light affects the brain, and even spends time with scientists attempting to detect broadcasts from extraterrestrials. Lively, informative, and packed with eureka moment stories, INVISIBLE LIGHT will delight anyone interested in gaining a deeper understanding of our world. …
