These glittering forms I view,
Methinks the busy restless world
Is pictured in a few.

Without the least acceleration.

In science:

Additionally, if the stellar mass-to-light ratio of UGC 12695 is increased to 1.7, a reasonable value for both HSB and LSB galaxies, there is no need to invoke any dark matter to explain the maximum observed rotational velocity at the last measured point of UGC 12695’s rotation curve.
Star Formation and Tidal Encounters with the Low Surface Brightness Galaxy UGC 12695 and Companions
On the other hand, it is quite likely that there is significant dark matter outside the observed radius (else the rotation curve would show some turn over), and thus we are merely viewing a lower limit of the galaxy’s rotational velocity.
Star Formation and Tidal Encounters with the Low Surface Brightness Galaxy UGC 12695 and Companions
From the rotation curve of UGC 12695 it is apparent that its near solid body rotation makes determining κ relatively easy.

Faraday rotation can only be a significant factor if the Faraday rotation sizescale is smaller than the length scale of the masing region (see Elitzur 1992 for details).
OH Zeeman Magnetic Field Detections Toward Five Supernova Remnants Using the VLA
The presence of such a correlation could argue against the possibility of significant Faraday rotation within the SNRs or may result from Faraday depolarization without significant net rotation.

The ground state is no longer invariant under O(3) rotations but only under O(2) rotations in the plane perpendicular to the spontaneous magnetization.

In rotating cylindrical vessel, filament-like polyeffectons originate from 3D isotropic net of polyeffectons and they tend to be oriented along the cylinder axis with their own rotation round their own axises in the direction opposite to that of cylinder rotation, as a consequence of angular momentum conservation.

If in Einstein-Haas effect a paramagnetic body starts rotating during remagnetizations as its flipping electrons transfer the angular momentum (associated with their spins) to the lattice, in the Barnett effect the rotating body shares its angular momentum with the electron subsystem causing magnetization.
Physics of Grain Alignment
Indeed, the D-G mechanism assumes that the relaxation rate is the same whether grain rotates in stationary magnetic field or magnetic field rotates around a stationary grain.
Physics of Grain Alignment
An alignment mechanism is efficient if the alignment time is a fraction of tgas for thermally rotating grains, but it may be many tgas if grains rotate suprathermally.
Physics of Grain Alignment
However, the baroclinic instability may have time to operate within the differentially rotating burning layer, potentially bringing it into rigid rotation.
Rotational Evolution During Type I X-Ray Bursts
This remains true as the atmosphere expands, since a rigidly rotating spherical shell stays rigidly rotating as it expands outwards (because the fractional change in the distance from the rotation axis is the same for all latitudes).
Rotational Evolution During Type I X-Ray Bursts
Thus to observe a single, coherent frequency requires either the atmosphere to be rigidly rotating, or the burning region to be vertically thin (Miller 2000), so the differential rotation across it is small.
