2. Autorotation - Wikipedia

   en.wikipedia.org/wiki/Autorotation

   Autorotation is a state of flight in which the main rotor system of a helicopter or other rotary-wing aircraft turns by the action of air moving up through the rotor, as with an autogyro, rather than engine power driving the rotor. [1] [2] [3] The term autorotation dates to a period of early helicopter development between 1915 and 1920, and ...

3. Solar rotation - Wikipedia

   en.wikipedia.org/wiki/Solar_rotation

   The solar rotation can be seen in the background of this false color video. Solar rotation varies with latitude. The Sun is not a solid body, but is composed of a gaseous plasma. Different latitudes rotate at different periods. The source of this differential rotation is an area of current research in solar astronomy.

4. Rotation around a fixed axis - Wikipedia

   en.wikipedia.org/wiki/Rotation_around_a_fixed_axis

   v. t. e. Rotation around a fixed axis or axial rotation is a special case of rotational motion around an axis of rotation fixed, stationary, or static in three-dimensional space. This type of motion excludes the possibility of the instantaneous axis of rotation changing its orientation and cannot describe such phenomena as wobbling or precession.

5. Optical rotation - Wikipedia

   en.wikipedia.org/wiki/Optical_rotation

   Optical rotation, also known as polarization rotation or circular birefringence, is the rotation of the orientation of the plane of polarization about the optical axis of linearly polarized light as it travels through certain materials. Circular birefringence and circular dichroism are the manifestations of optical activity.

6. 360-degree video - Wikipedia

   en.wikipedia.org/wiki/360-degree_video

   360-degree videos, also known as surround video, [1] or immersive videos [2] or spherical videos, [3] are video recordings where a view in every direction is recorded at the same time, shot using an omnidirectional camera or a collection of cameras. The term 360x180 can be used to indicate 360° of azimuth and 180° from nadir to zenith.

7. Wagon-wheel effect - Wikipedia

   en.wikipedia.org/wiki/Wagon-wheel_effect

   Video of a spinning, patterned paper disc. At a certain speed the sets of spokes appear to slow and rotate in opposite directions. The wagon-wheel effect (alternatively called stagecoach-wheel effect) is an optical illusion in which a spoked wheel appears to rotate differently from its true rotation. The wheel can appear to rotate more slowly ...
