Plane (tool)

A hand plane is a tool for shaping wood. When powered by electricity, the tool may be called a planer. Planes are used to flatten, reduce the thickness of, and impart a smooth surface to a rough piece of lumber or timber. Planing is used to produce horizontal, vertical, or inclined flat surfaces on workpieces usually too large for shaping. Special types of planes are designed to cut joints or decorative mouldings.

Hand planes are generally the combination of a cutting edge, such as a sharpened metal plate, attached to a firm body, that when moved over a wood surface, take up relatively uniform shavings, by nature of the body riding on the 'high spots' in the wood, and also by providing a relatively constant angle to the cutting edge, render the planed surface very smooth. A cutter which extends below the bottom surface, or sole, of the plane slices off shavings of wood. A large, flat sole on a plane guides the cutter to remove only the highest parts of an imperfect surface, until, after several passes, the surface is flat and smooth. When used for flattening, bench planes with longer soles are preferred for boards with longer longitudinal dimensions. A longer sole registers against a greater portion of the board's face or edge surface which leads to a more consistently flat surface or straighter edge. Conversely, using a smaller plane allows for more localized low or high spots to remain.

Plane (geometry)

In mathematics, a plane is a flat, two-dimensional surface that extends infinitely far. A plane is the two-dimensional analogue of a point (zero dimensions), a line (one dimension) and three-dimensional space. Planes can arise as subspaces of some higher-dimensional space, as with a room's walls extended infinitely far, or they may enjoy an independent existence in their own right, as in the setting of Euclidean geometry.

When working exclusively in two-dimensional Euclidean space, the definite article is used, so, the plane refers to the whole space. Many fundamental tasks in mathematics, geometry, trigonometry, graph theory and graphing are performed in a two-dimensional space, or in other words, in the plane.

Euclidean geometry

Euclid set forth the first great landmark of mathematical thought, an axiomatic treatment of geometry. He selected a small core of undefined terms (called common notions) and postulates (or axioms) which he then used to prove various geometrical statements. Although the plane in its modern sense is not directly given a definition anywhere in the Elements, it may be thought of as part of the common notions. In his work Euclid never makes use of numbers to measure length, angle, or area. In this way the Euclidean plane is not quite the same as the Cartesian plane.

Silver (Johnny Cash album)

Silver is the 62nd album by American country singer Johnny Cash, released on Columbia Records in 1979. It peaked at #28 on the albums chart. "(Ghost) Riders In The Sky" peaked at #2 on the singles chart; the two other singles, "Bull Rider" and "I'll Say It's True", reached #66 and #42, respectively. Other highlights include "The L & N Don't Stop Here Anymore" and "I'm Gonna Sit on the Porch and Pick on My Guitar". Recordings of "Cocaine Blues" had previously appeared on At Folsom Prison and Now, There Was a Song!, under the title "Transfusion Blues" on the latter. The album also featured production by Brian Ahern, who controversially introduced digital elements into the songs to the disapproval of some listeners. Silver was re-released in 2002 through Legacy Recordings, with remakes of two early Cash songs, "I Still Miss Someone" and "I Got Stripes," as bonus tracks; both are duets with George Jones. This is the last album that Marshall Grant, the original Tennessee Two bass player, played on. He departed from Cash's band the following year.

Silver (color)

Silver or Metallic gray is a color tone resembling gray that is a representation of the color of polished silver.

The visual sensation usually associated with the metal silver is its metallic shine. This cannot be reproduced by a simple solid color, because the shiny effect is due to the material's brightness varying with the surface angle to the light source. In addition, there is no mechanism for showing metallic or fluorescent colors on a computer without resorting to rendering software which simulates the action of light on a shiny surface. Consequently, in art and in heraldry one would normally use a metallic paint that glitters like real silver. A matte grey color like the swatch on this page could also be considered silver in color.

History

The first recorded use of silver as a color name in English was in 1481. In heraldry, the word argent is used, derived from Latin argentum over Medieval French argent.

Like turquoise, orange and purple, silver has no common rhyme.
