One of the most famous science books of our time, the phenomenal national bestseller that "buzzes with energy, anecdote and life. It almost makes you want to become a physicist" (Science Digest). Richard P. Feynman, winner of the Nobel Prize in physics, thrived on outrageous adventures. In this lively work that “can shatter the stereotype of the stuffy scientist” (Detroit Free Press), Feynman recounts his experiences trading ideas on atomic physics with Einstein and cracking the uncrackable safes guarding the most deeply held nuclear secrets—and much more of an eyebrow-raising nature. In his stories, Feynman’s life shines through in all its eccentric glory—a combustible mixture of high intelligence, unlimited curiosity, and raging chutzpah. Included for this edition is a new introduction by Bill Gates.
Drawn with exquisite detail and told in a voice that recalls the stylish gossip of the Flapper, Paul Levitt's debut novel will entertain readers with its uncanny evocation of an era when the fangster held a place of celebrity and a teenage girl could be his unwitting collaborator.
This new second edition, many years in the making, provides the reader with the information that is needed to understand both traditional mechanisms as well as the most modern and sophisticated security technology incorporated into locks and how to bypass them. The author presents extremely detailed theoretical and practical information in order to facilitate a thorough understanding of the complex subject matter.

ln this volume Tom Gunning examines the films of Fritz Lang not only as a stylistically coherent body of work, but as an attempt to portray the modern world through cinema. The world of modernity in which systems replace individuals is conveyed by Lang's mastery of cinematic set design, composition and editing. Lang presents not only a decades-long vision of cinematic narrative which can be compared to that of Alfred Hitchcock or Jean Renoir, but a view of modernity that relates strongly to the ideas of Adorno, Brecht, Benjamin and Kracauer. From the sweeping allegorical films of the 20s to the chilly and abstract thrillers of the 50s, Lang's films, Gunning claims, are 'among the most precious records of the twentieth century'. The Films of Fritz Lang immeasurably enriches our understanding of a great artist and, in so doing, reimagines what a film arlist is: an author who fades away even in being recognised and interpreted, an enigmatic figure at the junction of aesthetics, history, biography and theory.
