it was discovered by the American astronomer S.C. Chandler (1846-1913) in 1891--is superimposed on a
much slower forced precession, with a period of about 26,000 years, caused by the small gravitational torque
exerted on the Earth by the Sun and Moon, as a consequence of the Earth's slight oblateness. (See
Section 7.10.) Next: MacCullagh's formula Up: Rigid body rotation Previous: Euler angles
