Conduction

“ The power of electric conduction, being a transmission of force equal in velocity to that of light, appears to be tied up in and dependent upon the properties of the matter, and is, as it were, existent in them.

In experimental philosophy we can, by the phenomena presented, recognise various kinds of lines of force. ”

“ The form of conductors used by us has been adopted after considerable experience, as being the most simple, solid, durable, and capacious form of conductor for the safe conduction of heavy strokes of lightning. ”

“ Heat can move from one point to another in three basic ways: by conduction, by radiation, or by convection. Most often, all three methods of heat transfer are operating at the same time in a wildland fire. ”

“ No known process in nature is exactly reversible, that is to say, there is no known process by which we can connect a given amount of energy of one form into energy of another form, and then, reversing the process, reconvert the energy of the second form thus obtained into the original quantity of energy of the first form. In fact, during any transformation of energy from one form into another, there is always a certain portion of the energy changed into heat in the process of conversion, and the heat thus produced becomes dissipated and diffused by radiation and conduction. ”

“ Since the potential of a conductor is defined to be the work required to move a unit of positive electricity from the surface of the earth or from an infinite distance from all electricity to the surface of the conductor, it follows that the work done in putting a small charge dq into a conductor at a potential v is v dq. Let us then suppose that a conductor originally at zero potential has its potential raised by administering to it small successive doses of electricity dq. ”

“ The use of such a man would be that of a conductor to gather, from every part of the cloud of popular indignation, the scattered electricity which would waste itself in heat lightnings, and grasping it into one huge thunderbolt, let it fall like the messenger of an angry god among the triflers in the Capitol. ”

“ Addressing herself once more to the conductor, she asked him, "Do you love Jesus? I do, and if you love Him, He will let you ride to heaven on His railroad. I am going there and I wish you would go with me. I know Jesus will let me into heaven when I get there and He will let you in, too, and everybody that will ride on His railroad—yes, all these people. Wouldn't you like to see heaven and Jesus, and your little girl?"
These words, so pathetically and innocently uttered, brought a great gush of tears from all eyes, but most profusely from those of the conductor. ”

“ If your wife gets out of money on a journey the conductor goes down into his own pocket, and not into the railroad company's, and tells her not to worry, as he hands her what money she wants. If your child is taken sick on the journey, who but the conductor sees to sending a dispatch to you quicker than lightning, and who brings a pillow in from the sleeper and makes the little one as comfortable as he would his own little one at home? ”

“ I’ve been puzzling it out, and the best thing is for you to go to the nearest car-line you find; then ask the conductor how nigh it will take you to the Place. He’ll be kind to you, I know. They’re always obliging, the conductors are, and when it’s anybody like you, why they just seem to tear themselves to pieces to be nice. You’ll have no trouble, honey, not a mite. And when you get there, don’t forget to make your manners, pretty, like I’ve taught you. Say everything to cheer the lady up, if she seems down-hearted a bit, and good-by, good-by. Bless you, Mary Jane! ”

“ How do those mules on the flanks manage to avoid knocking their hoofs against the metal-ruts, and tripping themselves up? What a stand-and-deliver air the conductor has as he presents his snip-snap apparatus, like the brutal key of the primitive dentist, and viciously punches an orifice in your ticket! For these conductors, as for letter-carriers, I have a profound sympathy; they are over-worked and under-paid; and yet they enjoy motion in abundance. ”

“ If we call the reciprocal of the resistance of a conductor the conductivity of the conductor, then we may say that the conductivity of a multiple conductor is the sum of the conductivities of the component conductors. ”

“ If there was a conductor, state its dimensions—construction—mode of attachment to building—whether its top was pointed—distance of its upper terminal from the place struck—nature and extent of the connection between the conductor and the earth, and whether the earth was dry or moist—whether the conductor was itself injured—and whether the conductor or the point struck was the most salient object in the vicinity. Information is also desired, either verbally or by sketches, as to the position of metal spouting and lead roofing relatively to the point struck, and to the conductor. ”

“ The tops of the wheels and some of the legs of the horses of this char-a-banc, the end of the whip-lash and the lower jaw of the conductor—who was just beginning to yawn—were perceptibly in motion, but all the rest of the lumbering conveyance seemed still. And quite noiseless except for a faint rattling that came from one man's throat! And as parts of this frozen edifice there were a driver, you know, and a conductor, and eleven people! The effect as we walked about the thing began by being madly queer, and ended by being disagreeable. ”

“ If one conductor is insulated while all the surrounding conductors are kept at the zero potential by being put in communication with the earth, and if the conductor, when charged with a quantity of electricity, has a potential , the ratio of to is called the Capacity of the conductor. ”

“ The conductor stops, facing her, and meanwhile wearing on his face that air of pained resignation which is common to the faces of conductors on transportation lines that are heavily patronized by women travelers. In mute demand he extends toward her a soiled palm. ”

“ They sit in your lap; they stand on your toes; when they wish to pass, they simply push you. Everything in silence; they know that silence is golden, and they have the worship of gold. When the conductor wishes your fare, he gives you a poke, very serious, without a word. ”

“ Just hand it to the conductor—a tall, thin man, whose name is Sands."
"I'll do it right off. Ain't it lucky I found it?"
"Very. I'm deeply grateful. It would have put me to the greatest inconvenience if it had been lost. I'd like to know to whom I'm indebted." ”

“ When the mules had come to the water's edge, the conductor, back of them, wheeled about and said, with an air of triumph, and, to me, a ghastly smile, 'I am going no further; are you going on ? Instantly two men were seen on horseback, close at hand. One of them said. Turn, and go with us,' and com- manded the conductor (speaking with authority) to drive along the animals. They had been apprised of the movements of the robbers, and had come to my help. ”

“ She gives the conductor a look of surprise, if not anger, because he completes the curve before stopping to take her up. The old lady means business, and has never got it through her head that conductors have rights which she is bound to respect. ”

“ You see the conductor glance at his watch as he gives the engineer the starting-signal. You realize that the whole transportation system is merely an enormous piece of clockwork and that it, in turn, is a part of the vaster clockwork of modern civilization. ”

“ I have instant conductors all over me whether I pass or stop,
They seize every object and lead it harmlessly through me.
I merely stir, press, feel with my fingers, and am happy,
To touch my person to some one else's is about as much as I can stand. ”

“ THE PSYCHOLOGICAL BASIS OF CONDUCTINGThe conductor works largely through the instrumentality of instinctive imitation; that is, his methods are founded upon the fact that human beings have an innate tendency to copy the actions of others, often without being conscious that they are doing so. Thus, if one person yawns or coughs, a second person observing him has an instinctive tendency to do likewise. One member of a group is radiant with happiness, and very soon the others catch the infection and are smiling also ”

“ CONDUCTOR. A conductor occupies a difficult and trying position, and will always appreciate any courtesy shown him by a woman. If a woman desires a transfer, she should let him know in ample time; if she wants any information from him, she should ask him when paying her fare, and should indicate her desire to leave the car at least a block ahead of her street. ”

“ He stood before berth three, the lower, staring at something. We knew what he would say before he said it. 'There's a man in my berth!'
"The conductor stared at him; I stared at him. He turned to the conductor. 'Well, what are you going to do about it? I'm not paying for a filled berth!' 'Feel him,' the conductor stammered. 'Yes,' said I, 'feel him.' He looked oddly at us, but obediently he reached in to feel him. And shortly there were three white-faced people in the aisle of the extra Pullman, all staring stupidly at a man sleeping in the berth of a Pullman car. ”

“ You are now in Kansas and this is Kansas City.
3. I have observed that it is now the practice of the conductors to stick bits of paper in the hats of the passengers. They do this, I believe, to mark which ones they like best. The device is pretty, and adds much to the scenic appearance of the car. But I notice with pain that the system is fraught with much trouble for the conductors. The task of crushing two or three passengers together, in order to reach over them and stick a ticket into the chinks of a silk skull cap is embarrassing for a conductor of refined feelings. ”

“ I thought so all the while," and then he tells you where he wants to go, and shows you his check, and asks you if you think it is good for the trunk, and how far it is, and when he will get there, and you tell him. The conductor returns, he makes a grab at him, and he wants him to tell him when he will get there, and who keeps the best house, and how far it is from the depot, and whether that is really the best house or some other, and whether he meant three o'clock in the forenoon or afternoon, and the conductor doesn't tell him. ”

“ When a conductor is brought near the skin, the snap heard, the spark seen, and the sting felt, are all located together and believed to be different aspects of one entity, the 'electric discharge.' The space of the seen object fuses with the space of the heard object and with that of the felt object by an ultimate law of our consciousness, which is that we simplify, unify, and identify as much as we possibly can. Whatever sensible data can be attended to together we locate together. ”

“ But the division of a number representing the units of quantity of a conductor by the number representing its units of potential tells us the quantity which falls to the share of the unit of potential. Now the number C here we call the capacity of a conductor, and have substituted, thus, in the place of the old relative determination of capacity, an absolute determination. [33]
In simple cases the connexion between charge, potential, and capacity is easily ascertained. Our conductor, let us say, is a sphere of radius r, suspended free in a large body of air. ”

“ If you make the conductor out of your own head and fancy, it will be of no use. You must observe and follow humbly the laws which God has given to the lightning. You must make the conductor of metal wire, or it will be useless. You must make it run through glazed rings, or it will p. 139be only more dangerous than no conductor at all; for God who made the lightning chose that it should be so, and you must obey if you wish to conquer. ”

“ The hours of a conductor move up and down the day. Sometimes Jay punctured her first ticket at a time when you and I are asleep, and when the coster-barrows, waving with ferns and fuchsias, move up the Strand like Birnam Wood moving to Dunsinane. ”

“ This done, and herself comfortably settled, she was just remaking that she liked being close to the door, in case of a fire, when the conductor appeared, extending his hand officially towards her as the first one convenient. ”

“ Now when your home begins to drop out of sight behind, and the conductor comes along to punch your ticket rather than to comfort you, say to your heart "Go it, you you old ninnyhammer! It's natural for you to thump, but you can't interfere with business, you know!" ”

“ I know you in hurry, so freight train he make me nervous. I say polite to conductor I like to go faster. He laugh. I say polite to brakeman we must go faster. He make abusing speech. I climb into engine an' say polite to engineer to turn on steam. ”

“ If there is any necessity for communication, as with the conductor, we essay first to express ourselves by gesture, and then utter our desires with a certain hollow and remote effect, which is not otherwise to be described. I have sometimes tried to speak above my breath, when, being about to leave the car, I have made a virtue of offering my place to the prettiest young woman standing, but I have found it impossible ”

“ In considering the power of traction or impulsion necessary to move a body, whether on a canal or on a road. I must carefully distinguish that force which is requisite to put the body from a state of rest into a state of motion, from that which is requisite to sustain the motion when once imparted to it. ”

“ I am not certain with what degree of clearness he then held the doctrine afterwards so distinctly laid down by him [16] , that the moving conductor, as it cuts the lines of force, sums up the action due to an area or section of the lines of force. ”

“ Force, taking out his pocketbook.
“He can’t be allowed in the passenger car, sir,” replied the conductor.
“Not in the compartment that we have taken for our own convenience, and where he cannot possibly annoy anybody else?”
“No, sir; it is against the rules.”
“Oh, Mr. Conductor! please! please! He is such a good dog, and we love him so much! Indeed, he will not bite when he knows you don’t mean to hurt us! Please, Mr. Conductor, let him stay!” pleaded Elva. ”
