Nutation used in a sentence

Nutation in a sentence as a noun

Except that "due to nutation, an actual sidereal day is not quite so constant."Yeah.

And then people start wanting to change the time to a few thousand years in the past and now you have to factor in nutation and drift and ....

Yes but they need to include all the effects of all the nutations of the earth from the shortest a 19 year cycle caused by the moon to the 22,000 year cycle

Know what rotation, nutation and precession are, when and how they happen, etc...From that list I have read a little of Goldstein and some Symon.

Can someone explain to me why the authors neglect to mention nutation and precession on a vehicle that consists of non-negligible spinning masses?
