| Because of the precession of the equinoxes the tropical year is shorter by about 21 minutes than the sidereal year. |
| Then, in great precession we walked out to the field for commencement accompanied by bagpipes. |
| He considered the Euler angles and studied rotational problems which were motivated by the problem of the precession of the equinoxes. |
| As the tailwheel lifts during the takeoff run, gyroscopic precession tries to turn the plane left of centerline. |
| Because of the precession of the equinoxes, the equinox and solstice points have each moved westward about 30 degrees in the last 2,000 years. |
| Einstein's theory predicts that such gyroscopes will undergo geodetic precession merely because space-time is curved in the planet's vicinity. |
