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.
Woodblock Prints
It seems to me that many printmakers are suffering under a delusion. Looking at current trends, it appears that recent prints are simply copying fine art and painting. Some printmakers are working in the nanga style of painting. Others are attempting to reproduce the effects of oil. Some cleverly contrived prints are often difficult to distinguish from paintings done with a brush. The question arises: Why are these printmakers working in the medium of woodblock printing at all?
For prints to follow in the footsteps of painting has very little meaning. The art of the brush and palette should be left to the brush and palette.
The fountainhead of beauty
It might be said that the carving of a woodblock encompasses the greatest restriction on freedom. Printmakers come under extraordinary natural constraints on their work. Strangely enough, however, it is this restriction that is the fount of beauty. Constraint and restriction themselves become a blessing.
...Many people see a lack of freedom as the death knell of art. That may be true in the case of the fine arts, but in the handicrafts, lack of freedom is the fountainhead of beauty.
The preliminary sketch
Among the best woodblock prints are many that seem not to have adhered strictly to the preliminary sketch. The sketch simply indicated a general direction, and in many cases was not used at all. Or it was even improved upon in the process of carving and brought vividly to life; the woodblock qualities of the print were accentuated and highlighted.
