  | This image was uploaded in the PNG image format. However, it contains visible lossy compression artifacts. These artifacts may have come from the JPEG format, from saving a single colorful image as GIF instead of PNG or from saving an animated GIF using the incorrect settings (See also Dither). If possible, please provide a superior version of this file, derived from a non-lossy source (or with artifacts removed). If applicable, please replace all instances of the artifact version throughout Wikimedia projects, tag the old version with one of these templates, and remove this tag.

Summary
| Description |
English: This figure illustrates the nonzero vorticity of the timelike congruence of world lines of Langevin observers, who rotate about the axis r=0 in cylindrical coordinates with angular velocity ω.
In the figure, the red curve represents the world line a fiducial Langevin observer, together with two gold light cones with three frame vectors (the fourth frame vector is inessential and has been suppressed). The blue dashed curves represent the world lines of neighboring Langevin observers, which twist about the red curve. The cyan curve shows that the spatial frame vectors are rotating to radial symmetry, so the Langevin frame is spinning as well as non-inertial. This figure was created by User:Hillman using eog to convert to png format a jpg image exported from a Maple session. |

This diagram image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with
{{vector version available|new image name}}.
It is recommended to name the SVG file “Langevin Frame Cyl Vorticity.svg”—then the template Vector version available (or Vva) does not need the new image name parameter. |
