Pentagon Shape Quotes

The unit was housed in a facility built after the model of the Pentagon, not in the sense of seven sides, but in the sense that the hexagon-shaped building surrounded and enclosed a large open area.

Ninety feet directly beneath the center courtyard café in the middle of the Pentagon—previously known as the Ground Zero Cafe, because when the bomb dropped that was where it would most likely detonate—there is a deep subbasement office with ferroconcrete walls and a filtered air supply, accessible by discreet elevators and staircases from all five wings of the main building. It was designed as a deep command bunker back when the worst threats were raids by long-range Luftwaffe bombers bearing conventional explosives. Obsolescent since the morning of July 16, 1945—it won’t withstand a direct ground burst from an atom bomb, much less more modern munitions—it still possesses certain uses. Being deep underground and equidistant from all the other wings, it was well suited as a switch for SCAN, the Army’s automatic switched communications system, and later for AUTOVON. AUTOVON led to ARPANET, the predecessor of the internet, and the secure exchange in the basement played host to one of the first IMPs—Interface Message Processors—outside of academia. By the early 1980s a lack of rackspace led the DoD to relocate their hardened exchanges to a site closer to the 1950s-sized mainframe halls. And it was then that the empty bunker was taken over by a shadowy affiliate of the National Security Agency, tasked with waging occult warfare against the enemies of the nation. The past six months have brought some changes. There is a pentagonal main room inside the bunker, and within it there is a ceremonial maze, inscribed in blood and silver that glows with a soft fluorescence, converging on a dais at the heart of the design. The labyrinth takes the shape of a pentacle aligned with the building overhead: at each corner stands a motionless sentinel clad head to toe in occlusive silver fabric. Robed in black and crimson silk and shod in slippers of disturbingly pale leather, the Deputy Director paces her way through the maze. In her left hand she bears a jewel-capped scepter carved from the femur of a dead pope, and in her right hand she bears a gold-plated chalice made from a skull that once served Josef Stalin as an ashtray. As she walks she recites a prayer of allegiance and propitiation, its cadences and grammar those of a variant dialect of Old Enochian.

Suppose you could pick up a turtle, dip his tail into coloured ink, place him on a piece of paper and make him walk around so that his tail paints a spiral shape, a pentagon or a noughts and crosses grid? This adventure introduces you to different ways that you can create shapes or line drawings using code.

The American mathematician Jeffrey Weeks analysed the statistics of these fluctuations for manifolds with a variety of topologies. One possibility fitted the data very closely, leading the media to announce that the universe is shaped like a football (US: soccer ball). This was an inevitable metaphor for a shape that goes back to Poincaré: the dodecahedral space. In the early twenty-first century footballs were made by sewing or gluing together 12 pentagons and 20 hexagons to make what mathematicians call a truncated icosahedron – an icosahedron with the corners cut off. An icosahedron is a regular solid with 20 triangular faces, arranged five to a corner. The dodecahedron, which has 12 pentagonal faces, gets into the act because the centres of the faces of an icosahedron form a dodecahedron, so both solids have the same symmetries. ‘Football’ is more media-friendly, albeit technically imprecise.

Sun power’s image as the province of baling-wire hippies was at odds with reality. Today’s multibillion-dollar photovoltaic industry owes its existence mainly to the Pentagon and Big Oil. The first wide-scale use of solar panels had come in the 1960s: powering military satellites, which couldn’t use fossil fuels (too bulky to lift into space) or batteries (impossible to recharge in orbit). By the 1970s photovoltaics were cheaper, but the industry had acquired only one major new user: the petroleum industry. Some 70 percent of the solar modules sold in the United States were bought to run offshore drilling platforms.

A third measure, the convex hull, suggests putting a hypothetical rubber band around a district.5 The score is the percentage of the area surrounded by the hypothetical rubber band that is in the district. The measure would yield a high score for regular geometric shapes such as a square, rectangle, pentagon, and so on. However, a district in which portions have been cut away in order to avoid including certain populations would have lower scores. Each
