Among the unusual properties at work in gyroscopes is the resistance of a spinning object to being tilted. If set in a free-moving framework, such an object can provide a stable point of reference even if everything else around it—an airplane, for example—tilts. The effect is so strong that large gyroscopes can even prevent ships from rolling. Today, gyroscopes are used in missile guidance, automatic steering, and video game technology.
