Inertial wave lakes, and laboratory experiments. Rossby waves, geostrophic currents, and geostrophic winds are examples of inertial waves. Inertial waves are also likely to exist in the molten core of the rotating Earth. Inertial waves are restored to equilibrium by the Coriolis force, a result of rotation. To be precise, the Coriolis force arises (along with the centrifugal force) in a rotating frame to account for the fact that such a frame is always accelerating. Inertial waves, therefore, cannot exist without rotation. More complicated than tension on a string, the Coriolis force acts at a 90° angle to the direction of motion,
The Currents of Space is a form of cellulose. The possible destruction of Florina is predicted by Rik, a "spatio-analyst," who has had his mind manipulated by a "psychic probe" device, resulting in gross amnesia. When Rik gradually starts remembering his past, it produces a political crisis involving Sark, Florina, and Trantor. Rik, a native of the Earth, had discovered that Florina's sun is about to explode into a nova because it is being fed carbon by one of the outer-space "currents of space," supposedly rather like the currents of the ocean. It is also revealed finally that the special energetic wavelength of light
