Colour distribution of a Newton disc. The Newton disc, also known as the disappearing colour disc, is a well-known physics experiment with a rotating disc with segments in different colours (usually Newton's primary colours: red, orange, yellow, green, blue, indigo, and violet, commonly known by the abbreviation ROYGBIV) appearing as white (or off-white or grey) when it's spun rapidly about ...
The Fechner color effect is an illusion of color seen when looking at certain rapidly changing or moving black-and-white patterns. They are also called pattern induced flicker colors (PIFCs). The effect is most commonly demonstrated with a device known as Benham's top (also called Benham's disk). When the top is spun, arcs of pale color are ...
Wilhelm von Bezold's 1874 Farbentafel. A color wheel or color circle[1] is an abstract illustrative organization of color hues around a circle, which shows the relationships between primary colors, secondary colors, tertiary colors etc. Some sources use the terms color wheel and color circle interchangeably; [2][3] however, one term or the ...
The Spin Wheel is a British drill manoeuvre. The manoeuvre is not written down, but is instead passed down from one generation of musicians to the next. The manoeuvre is performed at the Trooping the Colour by The Massed Bands, Corps of Drums, and Pipes and Drums of His Majesty's Guards Division, and was designed after the addition of the then newly formed Regimental Bands of the Welsh and ...
The Bradley color wheel was a line of educational tools developed by Milton Bradley, of the Milton Bradley Company (MB), in 1895 as part of his wider color teaching system. [1] [2] Although the color system was primarily created for education, it had a wide influence. A notable example being its usage by Smithsonian ornithologist Robert ...
The rg chromaticity space is used in computer vision applications, and shows the color of light (red, yellow, green, etc.), but not its intensity (dark, bright). LMS color space (long, medium, short), a perceptual color space based on the response functions of the cones in the retina of the eye.
A gyroscope (from Ancient Greek γῦρος gŷros, "round" and σκοπέω skopéō, "to look") is a device used for measuring or maintaining orientation and angular velocity. [1][2] It is a spinning wheel or disc in which the axis of rotation (spin axis) is free to assume any orientation by itself. When rotating, the orientation of this axis ...
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 than the true rotation, it can appear stationary, or it can appear to rotate in the opposite direction from the true rotation ...
