Descripción o resumen: The latest advances in science were fully exploited in World War II. They included radar, sonar, improved radio, methods of reducing disease, primitive computers, the new science of operational research and, finally, the atomic bomb, necessarily developed like all wartime technology in a remarkably short time. Such progress would have been impossible without the cooperation of Allied scientists with the military. The Axis powers' failure to recognize this was a major factor in their defeat.
