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.

Pentagram (Pentagram album)

Pentagram is the first compilation album of Chilean metal band Pentagram, independently released first in Chile in 2000 and two years later in The Netherlands as a limited edition LP of 500 Copies vinilo.

Loon

The loons (North America) or divers (UK/Ireland) are a group of aquatic birds found in many parts of North America and northern Eurasia. All living species of loons are members of the genus Gavia, family Gaviidae and order Gaviiformes.

Description

The loon, the size of a large duck or small goose, resembles these birds in shape when swimming. Like ducks and geese but unlike coots (which are Rallidae) and grebes (Podicipedidae), the loon's toes are connected by webbing. The bird may be confused with cormorants (Phalacrocoracidae), which are not too distant relatives of divers and like them are heavy set birds whose bellies – unlike those of ducks and geese – are submerged when swimming. Flying loons resemble plump geese with seagulls' wings that are relatively small in proportion to the bulky body. The bird points its head slightly upwards during swimming, but less so than cormorants. In flight the head droops more than in similar aquatic birds.

Diver (Transformers)

Diver is the name of several fictional characters in the Transformers series and major characters in their respective anime series. Both are heroic characters who specialize in underwater combat.

Transformers: Generation 1

Diver is a marine biologist. Out of the Autobots, he is the best skilled in oceanic combat. He knows everything about Earths seas, and can even understand a little of the fish language. His weapons include his Sea Power Blaster and Sea Axe. His final attack is the "Screw Anchor", where he turns his Sea Anchor on its head, and launches it at the enemy like a boomerang.

Diver was fond of humans, and thought them special.

Animated series

Diver was a regular character featured in the early episodes of the Japanese exclusive series Transformers: Super-God Masterforce. In this series, Diver's human form was that of a marine biologist.

Eight thousand years ago, a starship containing the Autobot Pretenders Metalhawk, Lander, Diver and Phoenix pursued the Decepticon Pretenders Blood, Dauros and Gilmer to Neolithic-era Earth, where they crashed. Using their Pretender abilities, the Autobots adopted the form of humans - not using simple external shells like in the American fiction, but actually transforming the very structure of their bodies into an organic equivalent, shrinking down to normal human size to hide in plain sight among burgeoning humanity. The Decepticon Pretenders, on the other hand, adopted the forms of monstrous creatures, becoming feared as demons by early man. After many battles, the Autobots succeeded in defeating their enemies and sealing them away for thousands of years—Blood in the pyramids of Egypt, Gilmer in the ruins of Atlantis, and Dauros beneath the Nazca Lines in Peru.
