Spur (lunar crater)

Spur is a feature on Earth's Moon, a crater in the Hadley–Apennine region. Astronauts David Scott and James Irwin visited it in 1971, on the Apollo 15 mission, during EVA 2. Spur was designated Geology Station 7.

Spur is located on the north slope of Mons Hadley Delta, about 200 m above the plain to the north. It is east of the much larger St. George crater, and about 5 km south of the Apollo 15 landing site itself.

The astronauts found the "Genesis Rock", sample 15415, at Spur. The sample contains a large clast of anorthosite, and Dave Scott said "Guess what we just found! I think we found what we came for" as he examined the sample. They also found samples 15445 and 15455, so-called black and white breccias, which are thought to be impact melt breccia resulting from the Imrbrium basin impact event.

The crater was named by the astronauts, and the name was formally adopted by the IAU in 1973.

Typeface anatomy

Typeface anatomy describes the graphic elements that make up printed letters in a typeface.

The strokes of a letter are the lines that make it up. Strokes may be straight, as in k l v w x z, or curved, as in c o s. If straight, they may be horizontal, vertical, or diagonal; if curved, open or closed. Typographers also speak of an instroke, where one starts writing the letter, as at the top of a c f, and an outstroke, where the pen leaves off, as at the bottom of c e j k t y.

Typefaces are born from the struggle between rules and results. Squeezing a square about 1% helps it look more like a square; to appear the same height as a square, a circle must be measurably taller. The two strokes in an X aren't the same thickness, nor are their parallel edges actually parallel; the vertical stems of a lowercase alphabet are thinner than those of its capitals; the ascender on a d isn't the same length as the descender on a p, and so on. For the rational mind, type design can be a maddening game of drawing things differently in order to make them appear the same.

Spur route

A spur route is a usually short road forming a branch from a longer, more important route (typically a major road, freeway, Interstate Highway, or motorway). A bypass or beltway is never considered a true spur route as it typically reconnects with another or the same major road. Both loops and spurs can be forms of special route.

Canada

Ontario

In the province of Ontario, most spur routes are designated as A or B, such as Highway 17A, or 7B. A stands for "Alternate Route", and usually links a highway to a town's central core or main attraction, while B stands for "Business Route" or "Bypass", but are used when a main highway is routed around a town and away from its former alignment. The designation of "C" was used twice (Highway 3C and 40C), and is assumed to mean "Connector". Both highways have long since been retired and are now county roads. There was also one road with the D designation (Highway 8D, later the original Highway 102), and this may have stood for "Diversion", as it was along the first completed divided highway in Canada at the time (Cootes Drive in Hamilton).

Bône (département)

Bône is a former French département in Algeria which existed between 1955 and 1962.

Considered as a French province, Algeria was departmentalised on 9 December 1848. Three civil zones (départements) replaced the three beyliks into which the Ottoman former rulers had divided the territory. The easternmost of the three original Algerian departments was called Constantine. For over a century the town of Annaba, known at that time as Bône (and in classical times as Hippo), was a sub-prefecture in the département of Constantine: this changed in 1955.

On 7 August 1955 the eastern extremity of the former département of Constantine was split off and became the separate département of Bône. This administrative reorganisation was a response to the rapid population increase experienced across the territory, especially during the preceding decade.

The new coastal département of Bône covered an area of 25,367 km²: a population of 730,594 was recorded. The department comprised five sub-prefectures: these were La Calle, Clairfontaine, Guelma, Souk Ahras and Tébessa. A final but temporary change took place between 17 March 1958 and 7 November 1959, during which time the Tébessa sub-prefectures was transferred to the département of Batna.

Shades of white

Shades of white are colors that differ only slightly from pure white. Variations of white include what are commonly termed off-white colors, which may be considered part of a neutral color scheme.

In color theory, a shade is a pure color mixed with black (or having a lower lightness). Strictly speaking, a “shade of white” would be a neutral gray. This article is also about off-white colors that vary from pure white in hue, and in chroma (also called saturation, or intensity).

Colors often considered "shades of white" include, cream, eggshell, ivory, Navajo white, and vanilla. Even the lighting of a room, however, can cause a pure white to be perceived as off-white.

Off-white colors were pervasively paired with beiges in the 1930s, and especially popular again from roughly 1955 to 1975.

Whiteness measures the degree to which a surface is white in colorimetry.

Web colors

Below is a chart showing the computer web color shades of white. An achromatic white is a white color in which the red, green, and blue codes are exactly equal. The web colors white and white smoke are achromatic colors. A chromatic shade of white is a white color in which the red, green, and blue codes are not exactly equal, but are close to each other, which is what makes it a shade of white.
