Rapids

“ The odds be agin us to start with, for the smoke is thick and the fire will be in the bends at least half the way down, but it's our only chance; we must run the rapids."
"What about the dogs?"
"The pups must shirk for themselves," answered the old man. "I'm sorry, but the rapids be swift and the waters shaller on the first half of the stretch. ”

“ Hence, to the foot of the cañon, the metamorphic slates give place to granite, whose nobler sculpture calls forth expressions of corresponding beauty from the stream in passing over it,—bright trills of rapids, booming notes of falls, solemn hushes of smooth-gliding sheets, all chanting and blending in glorious harmony. When, at length, its impetuous alpine life is done, it slips through a meadow with scarce an audible whisper, and falls asleep in Moraine Lake. ”

“ On the 27th we came to the Cascade Rapids. The first or Little Cascade has about two feet fall, the second or Grand Cascade, a mile farther, is about a six foot sheer drop. ”

“ Which is the easier, the ascent on the descent of the rapids? cí kâi thuan híam căi; these rapids are very dangerous. thuan kâi cúi li kĭa, īu sà-sà, cĕng-cĕng cîeh, kù-chṳ́ kùe thuan kâi sî-liāu nâng-nâng kian; the rapids are steep, and full of projecting rocks, so that in passing them every one is in dread. ”

“ Like a traveller, who has been put out of his way, by the overflowing of some rapid stream, you have only had the fore-right path you were in overwhelmed. A few miles about, a day or two only lost, as I may say, and you are in a way to recover it; and, by quickening your speed, will get up the lost time. ”

“ At one time human beings wished to be shot along these tubes, but it was found that such rapid movement, although not felt, had an injurious effect, and it was therefore abolished. 'Why so fast?' said our statesmen, and our movements were limited to the average rate of one hundred miles an hour. We all agree now that that is fast enough. There is no need to push through to-day as if there was no to-morrow. Our lives are happy and full of leisure because we gave up hurrying. ”

“ This rapid comes down in so swift and sheer a volume that animals often lose all power of swimming in it, and perish. For, trickling from the topmost crests of the hills, it comes down the steep sides, catches on the rocks, and is shattered, falling into the deep valleys with a manifold clamour of waters; but, being straightway rebuffed by the rocks that bar the way, it keeps the speed of its current ever at the same even pace. ”

“ Imagine to yourself a human being on board, and the awful sensations he must have experienced on her striking the rapid, which appeared for a moment to the beholders to be her last; but, as I observed before, on her masts giving way, she again righted, and was turned sideways, in which course she proceeded to the second rapid, where she struck and stuck about a minute, and it seemed as though the elements made their last and desperate effort to drive her over this rapid. ”

“ Celerity of motion and brevity of duration are discovered to be its chief characteristics. Time is therefore depicted as flying,—fast, noiselessly, and uninterruptedly. It is a river, speeding on with imperceptible but resistless pace to the ocean of eternity. ”

“ We jog along at a respectable rate, not too fast and not too slow, say forty-five miles an hour top speed, and twenty-five mean, which allows us to see things to-day and remember what we saw yesterday. ”

“ Its differences are, the quick, slow, and moderate; because every body which is moved must be moved quickly, slowly, or intermediately, as to time; that is quick which is moved over a great distance in a short time; that is slow which is moved over a short distance in a long time ”

“ The speed of a body which has in this manner acquired any momentum whatever will, when converted into uniform motion, retain precisely such a speed as, during a time-interval equal to that of the fall, will carry the body through a distance equal to twice that of the fall. ”

“ And if you had gone by any circuitous route, which enabled you to arrive in time by traveling fast, the longer your route the less time you would judge that you had taken; the diminution of time would be continual as your speed approached that of light. ”

“ To put the matter more clearly, if a body were to continue its motion with the same speed which it had acquired during the first time-interval and were to retain this same uniform speed, then its motion would be twice as slow as that which it would have if its velocity had been acquired during two time-intervals. ”

“ The time of a step in quick running, compared to that in quick walking, is nearly as two to three, whilst the length of the steps are as two to one; consequently a person can run in a given time three times as fast as he can walk. In running, the object is to acquire a greater velocity in progression than can be attained in walking. ”

“ From a state of rest at the beginning of the fall, the speed gradually increases with the time, and the final velocity is greater still than that which the body had at any preceding instant during its descent. ”

“ Now, instead of reversing the levers, I had pulled them over so as to go forward with them, and when I came to look at these indicators I found that the thousands hand was sweeping round as fast as the seconds hand of a watch—into futurity.
'As I drove on, a peculiar change crept over the appearance of things. The palpitating greyness grew darker; then—though I was still travelling with prodigious velocity—the blinking succession of day and night, which was usually indicative of a slower pace, returned, and grew more and more marked. ”

“ And thus, it seems, we shall not be far wrong if we put the increment of speed as proportional to the increment of time; hence the definition of motion which we are about to discuss may be stated as follows: A motion is said to be uniformly accelerated, when starting from rest, it acquires, during equal time-intervals, equal increments of speed. ”

“ So great was the speed at which we were travelling, however, that this was very slow work. Sometimes the men would strain to their utmost and fail to get in an inch of the rope; at other times they came ahead more rapidly. ”

“ I, and many of the guests, examined the machine with our own eyes and our own touch.
A few minutes later my friend politely asked the guests to resume their seats. Then he proceeded,—
“By way of introduction I shall give a few well-known facts concerning the velocity of light. The speed of my machine will then be better understood. As is well known, the velocity of light is computed to be more than forty-two thousand geographical miles a second. [1] A ray of moonlight, therefore, reaches the earth in about a second and a half; sunlight arrives in about eight minutes. ”

“ But, seated on the old mail-coach, we needed no evidence out of ourselves to indicate the velocity. On this system the word was—Non magna loquimur, as upon railways, but magna vivimus. The vital experience of the glad animal sensibilities made doubts impossible on the question of our speed; we heard our speed, we saw it, we felt it as a thrilling; and this speed was not the product of blind insensate agencies, that had no sympathy to give, but was incarnated in the fiery eyeballs of an animal, in his dilated nostril, spasmodic muscles, and echoing hoofs. ”

“ But the moon alone moves with sufficient rapidity to act as a time indicator for terrestrial voyagers. It is hardly necessary to explain why rapidity of motion is important; but the following illustration may be given for the purpose. The hour-hand of a clock does in reality indicate the minute as well as the hour; yet, owing to the slowness of its motion, we regard the hour-hand as an unsatisfactory time-indicator, and only consider it as showing what hour is in progress. ”

“ If I pass along a street at some unheard-of speed, but with a uniform motion, its general aspect may, on account of the contraction caused by my velocity, be a little different from what it would seem to me if I were stationary. ”

“ Walk in the morning, but don't walk too fast. Do not sweep your aunts, the clouds, away too quickly, or it will go hard with the people in the Earth World." Then he said again, as Mink started off, "Don't be too fast when you walk or sweep." ”

“ Only in one case was I at all satisfied of being able to count the rate of speed by a stop-watch, and, if I am not mistaken, there were thirty in ten seconds; generally one's eye can no more follow the legs than it can the spokes of a carriage-wheel in rapid motion. If we take the above number, and twelve feet stride as the average pace, we have a speed of twenty-six miles an hour. ”

“ Antonyms: QUICKEN. Synonyms:
To quicken, in the sense here considered, is to increase speed, [298] move or cause to move more rapidly, as through more space or with, a greater number of motions in the same time. To accelerate is to increase the speed of action or of motion. A motion whose speed increases upon itself is said to be accelerated, as the motion of a falling body, which becomes swifter with every second of time. To accelerate any work is to hasten it toward a finish, commonly by quickening all its operations in orderly unity toward the result. ”

“ You have no chance to escape it, except by speed. If you do not make haste, it will be too late. In ten minutes’ time you may be enveloped, and then—quick, sir, I entreat you! Order your drivers to hurry forward as fast as they can! ”

“ Speed is the essential of motion, but the same particle in motion traverses a path. Motion, therefore, is speed and path, and can be measured in terms of space. Speed and path constitute motion.
The essential of time is persistence, but the relation of time is change; change may be measured in terms of motion. ”

“ It is enough for our author at present that we understand his object to be the investigation and examination of some phenomena of a motion so accelerated, (no matter what may be the cause,) that the momenta of velocity, from the beginning to move from rest, increase in the simple proportion in which the time increases, which is as much as to say, that in equal times are equal additions of velocity. ”

“ Assuming that the body moved in a straight line with a speed of seven miles a second, it is easy to show that after eight or nine hours it would have passed more under the influence of the sun than it was under that of the globe from which it had taken its rise. ”

“ Any steady pace, such as the walking of a man or a horse, or the floating of a raft carefully kept in the axis of the current, makes dead reckoning so exact, if long practiced, as often to astonish the surveyor himself, but every thing depends upon this steadiness of motion. ”

“ If two particles are carried with uniform motion, but each with a different speed, the distances covered by them during unequal intervals of time bear to each other the compound ratio of the speeds and time intervals. ”

“ What I would like though, is a couple of these Lassan thought-helmets. Not that you people are slow on the uptake, but we'd be a lot faster if we had them, and we're going to need all the speed we can get. ”

“ A flight with such speed, in the midst of winter, may be conceived as no agreeable task, especially in a country almost surrounded by mountains. The sudden order affected all, and things, which would have been scarcely noticed at another time, now appeared in the most conspicuous light. ”

“ There were gnats but no mosquitoes—at least none when we were in motion—and our friend Speed, guiding the car with a splendid technique, was still able between twists and turns and high speeds and low speeds to toss back tale after tale of a daring and yet childlike character, which kept me laughing all the while. Speed was so naïve. ”

“ From Right Habits of Motion Comes Speed of Motions. — Concentrating the mind on the next motion causes speed of motion. Under Scientific Management, the underlying thought of sequence of motions is so presented that the worker can remember them, and make them in the shortest time possible. ”

“ And the disciples of John and of the Pharisees used to fast: and they come and say unto him, Why do the disciples of John and of the Pharisees fast, but thy disciples fast not?
19 And Jesus said unto them, Can the children of the bridechamber fast, while the bridegroom is with them? as long as they have the bridegroom with them, they cannot fast. ”

“ There are not many things to be said; the methods, on all planes, are simple to tell, yet not so simple to do. All the written words on earth could not cover everything that the Initiate will want to know. Each faster presents a new problem, as each one will react to the Fast in his own particular way. ”

“ That particular and determinate degree of velocity in a wheel, whereby it turns once round precisely in twelve hours, is that which you call the power of a clock to show the time of the day; and because such a determinate velocity of motion is made use of by us for the measure of time, is it therefore really a new quality or power distinct from the motion itself? ”

“ Fastness to Weather, Light, and Air. Various people have attempted to set up standard degrees of fastness—for every shade of color is affected by the action of sun, light, and air—and as a result fabrics that remain without appreciable alteration for a month of exposure to direct summer sunlight are classified as “fast,” and those undergoing slight appreciable change under the same conditions as “fairly fast.” ”

“ COÖPERATION
We have already discovered the nature of motion in its absolute as speed and its relative as path. The speed of the ultimate particle has never been measured; but bodies as such have their specific speeds and one is greater than another. Speed of a body is the rate at which it changes its position, regardless of the change of position of its particles to one another. ”

“ In the experiments I describe, the conditions were most favorable for rapidity, for the connection between the signals and their movements might almost be called innate. It is instinctive to move the hand towards a thing seen or a skin-spot touched. But where the movement is conventionally attached to the signal, there would be more chance for delay, and the amount of practice would then determine the speed. ”
