Why toast lands jelly-side down : zen and the art of physics demonstrations /

Physics has the reputation of being difficult to understand and remote from everyday life. Robert Ehrlich, however, has spent much of his career disproving these stereotypes. In the long-awaited sequel to Turning the World Inside Out and 175 Other Simple Physics Demonstrations, he provides a new col...
