The verb " to nutate " was used by MIT physicist Peter Fisher on the television show Late Night with Conan O'Brien on February 8, 2008.

Novices are sometimes confused by finding that the Earth's rotational North pole does not point quite at the J2000 celestial pole at the epoch J2000.0; the reason is that the true pole of epoch nutates away from the mean one.

A company called McMasters, previously headed by successful American entrepreneur Harold McMaster, is also developing a nutating motor burning a mixture of pure hydrogen and pure oxygen that, it claims, will give 200 hp but weigh only one-tenth that of gasoline / air production automotive engines with the same output.

Due to its precession, Twinsun's axis of rotation would in time align itself with the axis of revolution of the binary system, nutating like a retrograde version of a child's top spinning down, with the eventual result that every location on the planet would experience only a brief periodic immersion in the twilight zone, as it witnessed the simultaneous rising of one sun and setting of the other.

Since the apparent motion was evidently caused neither by parallax nor observational errors, Bradley first hypothesized that it could be due to oscillations in the orientation of the Earth's axis relative to the celestial sphere a phenomenon known as nutation . 35 Camelopardalis was seen to possess an apparent motion which could be consistent with nutation, but since its declination varied only one half as much as that of ? Draconis, it was obvious that nutation did not supply the answer ( however, Bradley later went on to discover that the Earth does indeed nutate ).

A "'nutating disc engine "'( also sometimes called a "'disc engine "') is an internal combustion engine comprising fundamentally of one moving part and a direct drive onto the crankshaft . Initially patented in 1993, it differs from earlier internal combustion engines in a number of ways and utilizes a circular rocking or wobbling " nutating motion ", drawing heavily from similar steam-powered engines developed in the 19th century, and similar to the motion of the non-rotating portion of a swash plate on a swash plate engine.
