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.
Craft and Material in Digital Design
A little bit more about the stone
In the documentary Rivers and Tides, artist Andy Goldsworthy repeatedly struggles to stack stones into a sculptural cairn. Over and over the stones fall. Each time, Andy’s sculpture stands a little taller before the moment of failure. At a penultimate moment in the episode, the ever-patient Goldsworthy begins to look exasperated. He’s just staring at the rocks scattered on the ground, studying them intently. A curious passerby has watched him fail a few times, and Andy tells the man, “Every time, I learn a little bit more about the stone. I’m learning how it works.”
It is how we come to understand our medium
There is such a unique quality to experiential learning, through direct experience with a material. It cannot be substituted through lectures or books. It must be felt. It must be earned through time well spent, through making and failing and re-making. It is how we come to understand our medium.
If you’re a digital designer who doesn’t understand basic principles of computer science, or has never written a bit of code, or has never built a website, what are you doing? What can you say about the material you shape?
The idea that designers in the information age shouldn’t waste their time with this skill baffles me. It is woefully misguided advice.
A digital designer who has not learned the nature of their medium is a designer unprepared to argue for their vision. This is a designer who is unable to push back against the criticism of skeptical engineers. This is a designer who risks offering opinions instead of solutions.
If you are crafting experiences in the digital space, you should know what’s required to implement your ideas. You should try implementing it yourself, (if only to build empathy with your developers!)
