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 and the other Empire novels. Anthony Boucher and J. Francis McComas found "The Currents of Space" an advance from Asimov's previous work and described it as "first-rate entertainment [that] is so much more adroitly plotted than Asimov's previous ventures in this vein that it stands up as an intricate and constantly surprising spy-suspense story." The Currents of Space The Currents of Space is a science fiction novel by the American writer Isaac Asimov, published in 1952. It is the second (by internal series chronology) of three books labeled the "Galactic Empire" series, but it was the last of the three
