In astronomy, this explains why Polaris has not always been the North Star, and can also mean the slow movement of an orbit's perihelion about the sun.
The Thomas type of this corrects for special relativity, while the Larmor type of it uses this concept to predict the effect of an applied magnetic field on electrons and nuclei. An instance of this effect caused by the rotation of the Earth is demonstrated by a Foucault pendulum, and if the second Euler angle is not constant, nutation occurs in addition to this. In astronomy, this explains why Polaris has not always been the North Star, and can also mean the slow movement of an orbit's perihelion about the sun. Referring in general to a change in the orientation of a body's axis of rotation, for 10 points, name this concept from physics often applied to explain the motion of gyroscopes.
