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.
Narcissus and Goldmund
Duality
All existence seemed to be based on duality, on contrast. Either one was a man or one was a woman, either a wanderer or a sedentary burgher, either a thinking person or a feeling person – no one could breathe in at the same time as he breathed out, be a man as well as a woman, experience freedom as well as order, combine instinct and mind. One always had to pay for the one with the loss of the other, and one thing was always just as important and desirable as the other.
Fear of death
He thought that fear of death was perhaps the root of all art.
Pain and joy
In the light of the torch, as he stared with great curiosity into the face of the screaming woman, lying there in pain, he was struck by something unexpected: the lines in the screaming woman’s distorted face were little different than those he had seen in other women’s faces during the moment of love’s ecstasy. True, the expression of great pain was more violent and disfiguring than the expression of ultimate passion – but essentially it was not different, it was the same slightly grinning contraction, the same sudden glow and extinction.
Miraculously, without understanding why, he was surprised by the realization that pain and joy could resemble each other so closely.
Suddenly the letter has a tail
I believe that the petal of a flower or a tiny worm on the path says far more, contains far more than all the books in the library. One cannot say very much with mere letters and words. Sometimes I’ll be writing a Greek letter, a theta or an omega, and tilt my pen just the slightest bit; suddenly the letter has a tail and becomes a fish; in a second it evokes all the streams and rivers of the world, all that is cool and humid, Homer’s sea and the waters on which Saint Peter wandered.
All that is beautiful and lovely
You are so handsome and you look so happy. But deep inside your eyes there is no gaiety, there is only sorrow, as though your eyes knew that happiness did not exist and that all that is beautiful and lovely does not stay with us long.
