Precession (disambiguation)

Precession (disambiguation)

Precession refers to a specific change in the direction of the rotation axis of a rotating object, in which the second Euler angle (angle of nutation) is constant

Precession may specifically mean:

  • Precession is the name of one of the Euler rotations
  • Axial precession (astronomy) — the precession of the Earth's axis of rotation (also known as the "precession of the equinoxes"), or similar
  • de Sitter precession — a general relativistic correction to the precession of a gyroscope near a large mass such as the Earth
  • Larmor precession — the precession of the magnetic moments of electrons, atomic nuclei, and atoms about an external magnetic field
  • Lense-Thirring precession — a general relativistic correction to the precession of a gyroscope near a large rotating mass such as the Earth
  • Precession (mechanical) — the process of one part rotating with respect to another due to fretting between the two
  • Thomas precession — a special relativistic correction to the precession of a gyroscope in a rotating non-inertial frame

Precession can also refer to change in the direction of an axis other than an axis of rotation:

  • Apsidal precession, perihelion precession, or orbital precession, the rotation of the orbit of a celestial body

Famous quotes containing the word precession:

    But how is one to make a scientist understand that there is something unalterably deranged about differential calculus, quantum theory, or the obscene and so inanely liturgical ordeals of the precession of the equinoxes.
    Antonin Artaud (1896–1948)
