A trick in which the board rotates 360-degrees while the skateboarder turns 180 degrees in the same direction above it. If the skateboarder rotates in the opposite direction of the skateboard it is called Anti-Bigspin. This can be done in any direction from any position, and in freestyle is often done following a Casper.
A shove-it (or shuvit) is a skateboarding trick where the skateboarder makes the board spin 180 degrees (or more) without the tail of the board hitting the ground under their feet. There are many variations of the shove-it but they all follow the same principle: The skateboarder's lead foot remains in one spot, while the back foot performs the ...
A sphere rotating (spinning) about an axis. Rotation or rotational motion is the circular movement of an object around a central line, known as an axis of rotation.A plane figure can rotate in either a clockwise or counterclockwise sense around a perpendicular axis intersecting anywhere inside or outside the figure at a center of rotation.
Animation of a half-turn ambigram of the word ambigram, with 180-degree rotational symmetry [1]. An ambigram is a calligraphic composition of glyphs (letters, numbers, symbols or other shapes) that can yield different meanings depending on the orientation of observation.
Performed by pushing with the front foot directly off the nose of the board after an ollie, causing the board to rotate almost vertically 180 degrees towards the frontfoot between the rider's legs while flipping the board 180 degrees so it lands wheels down. Carlin has described the trick as "Pretty much a varial flip that goes down."
In the Euclidean plane, a point reflection is the same as a half-turn rotation (180° or π radians), while in three-dimensional Euclidean space a point reflection is an improper rotation which preserves distances but reverses orientation. A point reflection is an involution: applying it twice is the identity transformation.
An object with an axial tilt up to 90 degrees is rotating in the same direction as its primary. An object with an axial tilt of exactly 90 degrees, has a perpendicular rotation that is neither prograde nor retrograde. An object with an axial tilt between 90 degrees and 180 degrees is rotating in the opposite direction to its orbital direction.
Martin Joe Laurello (born Martin Emmerling, 1885–1955), also known by the stage names Human Owl and Bobby the Boy with the Revolving Head, was a German-American sideshow performer and biological rarity who could turn his head 180 degrees to the rear.
