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.
On Motivation
I’ve had this (semi-vague) idea that I want to write about what keeps us excited to work on Are.na, on the occasion of its 10th (yes 10th) birthday. While writing generally is a tricky process for me, this subject motivation is even trickier.
In turning this subject around in my mind, and thinking about all the people and things that have been influential, I have some idea about what keeps us going.
Nodal points
I started thinking about all the other important “nodal points” (I don’t know what else to call this) of people, places, books, albums, websites, etc. that all played a part in shaping who I am as a person and what I think is important. These points are a combination of seeking things out myself and getting a recommendation that felt like it was actually for me. A mixture of both passive and active knowledge acquisition.
ultimately, it's the totality of those “nodal points” that indicate one’s own unique perspective. It doesn’t matter if you specifically sought out the nodal point or not, it’s the recognition that counts. When you encounter a piece of life-changing information (no matter how large the change part is), you are simultaneously discovering and creating “yourself,” becoming incrementally more complete. Your perspective (where your gaze is directed) is made up of a meandering line through these points. Learning (or maybe some precursor to learning) is a lot about developing the intuition to recognize when something you find in the world is going to be a nodal point for you.
Infinite varieties of contexts
Over the course of 10 years of using Are.na, I have fully adopted the view that any piece of information can be important to a person given the right context. And on Are.na, pieces of information can be arranged in infinite varieties of contexts – their respective meaning shifts as the proximate information shifts. In other words, the more connections a block has, the more opportunities it has to be a nodal point.
A lifelong project
One question that is still hard to answer after 10 years of working on Are.na is “what is the long term vision?” This is difficult for a few reasons.
One reason is that we have to calibrate our definition of long term with the person who is asking the question. Are.na is a lifelong project. Our ideal outcome as a company is not becoming the next Facebook (god forbid), it’s becoming the next Nishiyama Onsen Keiunkan, a hot spring hotel in Japan, and one of the world’s oldest businesses (founded in 705 AD).
Growing in the correct way
It often feels like Are.na itself has its own needs and desires—that Are.na has its own personal intuition. And that we (you and I) are figuring out what it wants to be together. We (the organization that works on Are.na) have a very defined sense of how things should be done and why building Are.na is important, but we try not to be overly dogmatic about what exactly it should evolve into.
…We’ve long had the sense that it’s possible to cultivate an experience on the Internet that is more calm, thoughtful, and introspective. And we’ve long had the view that this is possible not from a technology-oriented approach, but from an approach that is more soft, more personal, and more intuitive.
…If we are the blade, what is the shield? I think it’s speed: The dominant model for online platforms (especially social platforms) is speed and scale at all costs. But to us, growing Are.na in the correct way is more important than growing it quickly.
