Tracing Power Lines with the Pylon Appreciation Society
Pylons
Not all the towers along a transmission line are identical. Look closely at a tower where the line makes a sharp turn and you will likely find it is wider and beefier than other towers along the route. The added strength and weight are needed to resist the unbalanced pull of the conductors, which might overturn an ordinary tower. These special towers are called deviation or angle towers.
The transmission-line tower everybody knows is an Erector Set latticework of steel girders and diagonal braces. The techniques for designing and building these towers are the same ones used in constructing steel bridge trusses or crane booms. The individual pieces can be made cheaply from rolled steel and then bolted together on the site. This last point is more important than it might seem: transporting a fully assembled tower 100 feet tall is an awkward and expensive business.
A haunting, syncopated music
"Rappers" on the roof of the electrostatic precipitator knock the accumulated dust free, letting it fall into the storage hopper. Each rapper is the size and shape of a baseball bat. Inside is an electromagnet that pulls a steel plunger upward, then allows it to fall again, producing a sharp knock. The rappers are energized at seemingly random intervals, producing a haunting, syncopated music. (The rhythm seemed more modern jazz than rap.)
Safety cut rope axe man
In the first nuclear reactor, constructed by Enrico Fermi in 1942 under the bleachers of the University of Chicago football stadium, the control rods were held up by a manila rope. A man with an axe was told to cut the rope if the reactor got out of hand. This "safety cut rope axe man" is supposedly the origin of the term SCRAM for an emergency shutdown procedure.
Color coding
Telephone wires erupt in a multicolor cascade in a ground-level, pedestal-type splice case on a city street.
Dividing the set of 10 colors into two contrasting groups of 5 allows for exactly 25 combinations with one color from each group; thus, each pair in a bundle can be uniquely colored. A similar color code is applied to the ribbons that bind together all the pairs in a bundle, and to those of the superbundles. The result is highly festive! A specific wire might be identified as the blue-red conductor within the orange-black bundle within the brown-yellow superbundle.
Phenomenal: An Introduction
Aesthetic palate cleansing
During the 1960s and 1970s, light became the primary medium for a loosely affiliated group of artists working in Greater Los Angeles who were more intrigued by questions of perception than by the notion of crafting discrete objects.
...Often with modest means (a bolt of scrim, a sheet of glass, a bucket of resin, an open window) these artists engaged in a kind of aesthetic palate cleansing, shaking off the art-historical weight and heavy impasto of midcentury painting as it had been influentially practiced in New York and San Francisco.
Not intended to be read until you have seen
This is not a catalogue because there is no list of works. The exhibition will comprise three spaces in which three artists will have made their art. At the moment of writing we are not sure exactly what they will do—and we cannot know how what they do will appear to us. Therefore we cannot attempt to help you perceive it. So this is also not truly an introduction to the art. It is not intended to be read until you have seen the exhibition.
A vaporous middle-world
In between these two extremes is a room with three constructions by Robert Irwin. These can be read as individual works of art but their function here is primarily that of creating a climate of fastidious ambiguity. Light turns into a new kind of material; new kinds of material are fused into light; a vaporous middle-world stands midway between total black (Bell) and total white (Wheeler)
