Pentagram

A pentagram (sometimes known as a pentalpha or pentangle or a star pentagon) is the shape of a five-pointed star drawn with five straight strokes.

The word pentagram comes from the Greek word πεντάγραμμον (pentagrammon), from πέντε (pente), "five" + γραμμή (grammē), "line". The word "pentacle" is sometimes used synonymously with "pentagram" The word pentalpha is a learned modern (17th-century) revival of a post-classical Greek name of the shape.

Geometry

The pentagram is the simplest regular star polygon. The pentagram contains ten points (the five points of the star, and the five vertices of the inner pentagon) and fifteen line segments. It is represented by the Schläfli symbol {5/2}. Like a regular pentagon, and a regular pentagon with a pentagram constructed inside it, the regular pentagram has as its symmetry group the dihedral group of order 10.

Construction

The pentagram can be constructed by connecting alternate vertices of a pentagon; see details of the construction. It can also be constructed as a stellation of a pentagon, by extending the edges of a pentagon until the lines intersect.

Pentagram (design studio)

Pentagram is a design studio that was founded in 1972 by Alan Fletcher, Theo Crosby, Colin Forbes, Kenneth Grange, and Mervyn Kurlansky in Needham Road, West London, UK. They now have offices in London, New York, San Francisco, Austin and Berlin.

History

Pentagram was founded on the premise of collaborative interdisciplinary designers working together in an independently owned firm of equals. Theo Crosby claimed the structure was suggested to him by his experience of working on the seminal late-1950s exhibition This is Tomorrow: "it was my first experience at a loose, horizontal organisation of equals. We have brought it ... to a kind of practical and efficient reality at Pentagram". The firm currently comprises 19 partner-designers in 5 cities, each managing a team of designers and sharing in common overhead and staff resources. The partners in each office share incomes equally and all the partners own an equal portion of the total firm. This equality, along with the tradition of periodically inviting new members to join, renews the firm while giving even the newest members an equal footing with the partners of long standing. This 'flat' organization (there are no executive officers, CEO, CFO or board, other than the entire group) along with the self-capitalized finances of the business, allows equal participation and control of the group's destiny by the members.

FIFA U-17 World Cup

The FIFA U-17 World Cup, founded as the FIFA U-16 World Championship, later changed to the FIFA U-17 World Championship and known by its current name since 2007, is the world championship of association football for male players under the age of 17 organized by Fédération Internationale de Football Association (FIFA).

The first edition was staged in 1985 in China, and tournaments have been played every two years since then. It began as a competition for players under the age of 16 with the age limit raised to 17 from the 1991 edition onwards. The most recent tournament was hosted by Chile and won by Nigeria, with the next edition being hosted by India in 2017.

Nigeria is the most successful nation in the tournament's history, with five titles and three runners up. Brazil is the second most successful with three titles and two runners up. Ghana and Mexico have won the tournament twice.

A corresponding tournament for female players, the FIFA U-17 Women's World Cup, began in 2008, with North Korea winning the inaugural tournament.

Basement

A basement or cellar is one or more floors of a building that are either completely or partially below the ground floor. Basements are generally used as a utility space for a building where such items as the boiler, water heater, breaker panel or fuse box, car park, and air-conditioning system are located; so also are amenities such as the electrical distribution system, and cable television distribution point. However, in cities with high property prices such as London, basements are often fitted out to a high standard and used as living space.

In British English, the word "basement" is used for underground floors of, for example, department stores, but the word is only used with houses when the space below their ground floor is habitable, with windows and (usually) its own access. The word cellar or cellars is used to apply to the whole underground level or to any large underground room. A subcellar is a cellar that lies further underneath.

Purpose, geography, history

A basement can be used in almost exactly the same manner as an additional above-ground floor of a house or other building. However, the use of basements depends largely on factors specific to a particular geographical area such as climate, soil, seismic activity, building technology, and real estate economics.
