He resolved to measure anew with his own eye and with his own hand the constants of aberration and of nutation.
"Great Astronomers" by R. S. Ball
Why did he not continue in the same spot, except for the slow change caused by the nutation or nodding of Venus?
"A Trip to Venus" by John Munro
In another place we shall inquire into the cause of the discrepancy as given by the nutation of the earth.

The position of the equinox as affected by nutation.
"The Sailor's Word-Book" by William Henry Smyth
"The Story of the Heavens" by Robert Stawell Ball
Nutation is a real "nodding" of the terrestrial axis produced by the dragging of the moon at the terrestrial equatorial protuberance.
"A Popular History of Astronomy During the Nineteenth Century" by Agnes M. (Agnes Mary) Clerke
Sometimes this path is loopy, and its little nods correspond to nutation.
"Pioneers of Science" by Oliver Lodge
Commonly this nutation is slight or hardly observable.
"The Elements of Botany" by Asa Gray
Nutation is one of the great discoveries of James Bradley (1747).

In news:

Of most interest to me is the process of "nutation and "counter-nutation as described by I.

In science:

Also, some parameters affecting performance may only be evaluated from data that are obtained over a longer term, such as dependencies on seeing, temperature, and the effects caused by precession or nutation.
A Prototype for the PASS Permanent All Sky Survey
The nutator could only operate reliably under quiet or moderately windy conditions (a few m/s).
Evaluation of the ALMA Prototype Antennas
That implies the nutations between molecular states with various I values.
Prototype model for nuclear spin conversion in molecules: The case of "hydrogen"
If the angular momentum J does not happen to be along one of the grain’s principal axes, then the grain’s angular velocity ω will not be parallel to J, and will nutate around J, with a nutation rate that will be smaller than (but comparable to) the rotation rate.
Astrophysics of Dust in Cold Clouds
Because the rotation and nutation are both rapid, we will quickly obtain a rotation-nutation average of the grain orientation.
