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.
The Blue Cliff Record
Mountains are mountains
Before attaining enlightenment,
mountains are mountains, rivers are rivers.At the moment of enlightenment,
mountains are no longer mountains,
nor are rivers rivers.After attaining enlightenment,
mountains are mountains, rivers are rivers.No door at which to knock
Penetrating the Blue Cliff, you will open
the eye within eyes
and realizing life through the Blue Cliff,
you yourself will become a torch,
the light beyond light.Being so, you will find no door at which to knock, nor any door to be opened.
The miraculous bones of the ancients
A Ch'an master once wrote that the wise enshrine the miraculous bones of the ancients within themselves; that is, they do not regard teachings of ways to enlightenment as an external body of knowledge or information to be possessed as an acquisition or believed or revered as inflexible dogma, but rather apply it as far as possible to themselves and their situations, vivifying the way of enlightenment with their own bodies and lives, not just in their thoughts. It is therefore a matter of course that new Buddhist literature has been produced; for the Buddhist canon is not closed, as long as people continue the search for enlightenment.
Ch'an was referred to by its followers as the "school of the patriarchs" because it was transmitted by a living succession of human exemplars; not a school of doctrine, or philosophical or scholastic interpretation, it was not based on any particular scripture, but on the direct experience of the enlightened mind, by whatever means currently necessary.
What did you see when you were there?
Ch'an masters tell us to look right where we stand and step: they ask what is there, is there anything, who are you and where do you come from, what did you see and hear when you were there?—in a hundred ways they try to make us wake up, clear our minds, and face reality directly.
I have pacified your mind
Bodhidharma, the first Patriarch of Ch'an in China, was asked by Hui K'e, the future Second Patriarch, so pacify his mind for him; Bodhidharma said, "Bring me your mind and I will pacify it for you." Hui K'e said, "When I search for my mind, I cannot find it." Bodhidharma said, "I have pacified your mind for you." At this Hui K'e was enlightened.
In one there are many; in two, one
The ultimate path is without difficulty;
Speech is to the point, words are to the point.
In one there are many kinds;
In two there is no duality.It's dark outside
As soon as Te Shan crossed the threshold he said, "Long have I heard of Lung T'an (Dragon Pond), but now that I've arrived here, there's no pond to see and no dragon appears." Master Lung T'an came out from behind a screen and said, "You have really arrived at Lung T'an." Te Shan bowed and withdrew.
During the night, Te Shan entered Lung T'an's room and stood in attendance till late at night. Lung T'an said, "Why don't you go?" Te Shan bade farewell, lifted up the curtain, and went out; he saw that it was dark outside, so he turned around and said, "It's dark outside." Lung T'an lit a paper lantern and handed it to Te Shan; as soon as Te Shan took it, Lung T'an blew it out. Te Shan was vastly and greatly enlightened.
