On personal computers, the turbo button is a button which provides two run states for the computer: normal speed or an enhanced "turbo" speed. It was relatively common on personal computers using the Intel 80286, Intel 80386 and Intel 80486 processors, from the mid 1980s to mid 1990s.

The name is inspired by turbocharger, a turbine-driven forced induction device that increases an engine's power and efficiency.

Ernst Florens Friedrich Chladni (German: [ˈɛʁnst ˈfloːʁɛns ˈfʁiːdʁɪç ˈkladnɪ]; 30 November 1756 – 3 April 1827) was a German physicist and musician. His most important work, for which he is sometimes labeled the father of acoustics, included research on vibrating plates and the calculation of the speed of sound for different gases. He also undertook pioneering work in the study of meteorites and is regarded by some as the father of meteoritics.

Pumpable ice (PI) technology is a technology to produce and use fluids or secondary refrigerants, also called coolants, with the viscosity of water or jelly and the cooling capacity of ice. Pumpable ice is typically a slurry of ice crystals or particles ranging from 5 micrometers to 1 cm in diameter and transported in brine, seawater, food liquid, or gas bubbles of air, ozone, or carbon dioxide.

John Colter (c.1770–1775 – May 7, 1812 or November 22, 1813) was a member of the Lewis and Clark Expedition (1804–1806). Though party to one of the more famous expeditions in history, Colter is best remembered for explorations he made during the winter of 1807–1808, when he became the first known person of European descent to enter the region which later became Yellowstone National Park and to see the Teton Mountain Range. Colter spent months alone in the wilderness and is widely considered to be the first known mountain man.

The moving sofa problem or sofa problem is a two-dimensional idealisation of real-life furniture-moving problems and asks for the rigid two-dimensional shape of largest area A that can be maneuvered through an L-shaped planar region with legs of unit width. The area A thus obtained is referred to as the sofa constant. The exact value of the sofa constant is an open problem.

Domain tasting is the practice of temporarily registering a domain under the five-day Add Grace Period at the beginning of the registration of an ICANN-regulated second-level domain. During this period, a registration must be fully refunded by the domain name registry if cancelled. This was designed to address accidental registrations, but domain tasters use the Add Grace Period for illegal purposes.

🔗 Color

Impossible colors (forbidden, non-physical, unrealizable or chimerical colors) are supposed colors that do not appear in ordinary visual functioning. Non-physical colors are those notionally resulting from combinations of retinal outputs which cannot arise in normal vision. Chimerical colors are perceived, typically transiently, through contrast effects.
