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 Collected Poems of Emily Dickinson
The brain is wider than the sky
The brain is wider than the sky,
For, put them side by side,
The one the other will include
With ease, and you beside.The brain is deeper than the sea,
For, hold them, blue to blue,
The one the other will absorb,
As sponges, buckets do.The brain is just the weight of God,
For, lift them, pound for pound,
And they will differ, if they do,
As syllable from sound.The brain within its groove
The brain within its groove
Runs evenly and true;
But let a splinter swerve,
T'were easier for you
To put the water back
When floods have slit the hills,
And scooped a turnpike for themselves,
And blotted out the mills!What if I say I shall not wait?
What if I say I shall not wait?
What if I burst the fleshly gate
And pass, escaped, to thee?The Caspian
The Caspian has its realms of sand,
Its other realm of sea;
Without the sterile perquisite
No Caspian could be.We outgrow love
We outgrow love like other things
And put it in the drawer,
Till it an antique fashion shows
Like costumes grandsires wore.I died for beauty
I died for beauty, but was scarce
Adjusted in the tomb,
When one who died for truth was lain
In an adjoining room.He questioned softly why I failed?
"For beauty," I replied.
"And I for truth, — the two are one;
We brethren are," he said.The morning after death
The bustle in a house
The morning after death
Is solemnest of industries
Enacted upon earth,—The sweeping up the heart,
And putting love away
We shall not want to use again
Until eternity.Because I could not stop for Death
Because I could not stop for Death,
He kindly stopped for me;
The carriage held but just ourselves
And Immortality.
