Book Description
Werner Heisenberg's genius and his place at the forefront of modern physics are unquestioned. His decision to remain in Germany throughout the Third Reich and his role in Hitler's atomic bomb project are still topics of heated debate. UNCERTAINTY is David Cassidy's compelling portrait of this brilliant, ambitious, and controversial scientist. It is the definitive Heisenberg biography, as well as a striking evocation of the development of quantum physics, the rise of Nazism, and the dawn of the atomic age.

Book Description
The gripping, entertaining, and vividly-told narrative of a radical discovery that sent shockwaves through the scientific community and forever changed the way we understand the world. Werner Heisenberg’s “uncertainty principle” challenged centuries of scientific understanding, placed him in direct opposition to Albert Einstein, and put Niels Bohr in the middle of one of the most heated debates in scientific history. Heisenberg’s theorem stated that there were physical limits to what we could know about sub-atomic particles; this “uncertainty” would have shocking implications. In a riveting and lively account, David Lindley captures this critical episode and explains one of the most important scientific discoveries in history, which has since transcended the boundaries of science and influenced everything from literary theory to television.

Book Description
Personal letters reveal the quandary of a prominent German physicist during the Nazi years and the strength he shared with his loving wife Nobel Prize–winning physicist Werner Heisenberg lived far from his wife, Elisabeth, during most of the Second World War. An eminent scientist, Werner headed Germany’s national atomic research project in Berlin, while Elisabeth and their children lived more safely in Bavaria. This selection of more than 300 letters exchanged between husband and wife reveals the precarious nature of Werner’s position in the Third Reich, Elisabeth’s increasingly difficult everyday life as the war progressed, and the devoted relationship that gave strength to them both. These letters provide a fascinating new perspective on Werner’s much-debated wartime work and his attitude toward the atomic bomb. They also shed light on his reluctance to emigrate despite the urging of friends. An excerpt from his private diary, an introduction and notes by his daughter, and a selection of personal family photographs complete this compelling volume.

Book Description
A clear, plain-English guide to this complex scientific theory String theory is the hottest topic in physics right now, with books on the subject (pro and con) flying out of the stores. String Theory For Dummies offers an accessible introduction to this highly mathematical "theory of everything," which posits ten or more dimensions in an attempt to explain the basic nature of matter and energy. Written for both students and people interested in science, this guide explains concepts, discusses the string theory's hypotheses and predictions, and presents the math in an approachable manner. It features in-depth examples and an easy-to-understand style so that readers can understand this controversial, cutting-edge theory.
