(1.) If milling tools operate faster than planing or turning tools, why are they not more employed?��(2.) How may the effect produced by cutting tools generally be computed?��(3.) To what class of work are milling machines especially suited?��(4.) Why do milling processes produce more accurate dimensions than are attainable by turning or planing?��(5.) Why can some branches of manufacture be said to depend on milling processes?Unable to check Dick, his younger chum had to stand, listening while Dick related some of their most recent adventures.このページの先頭です
ONE:The Destruction of Dinant"In Cherath she saved the life of a good many. As it was alleged that there had been shooting, the priest, the chaplain, a retired priest, eighty years old, the mayor, and several leading citizens were condemned to be shot. None, not even the priest, was able to defend himself, as they knew not a word of German, and could not make themselves understood. Mrs. de Villers, who speaks German fluently, explained that the spot where the shooting was alleged to have taken place was not part of Cherath at all.

ONE:Meanwhile a new and powerful agency was about to interpose with decisive effect in the doubtful struggle. This was the study of mathematics. Revived by the Arabians and never wholly neglected during the Middle Ages, it had profited by the general movement of the Renaissance, and was finally applied to the cosmical problem by Galileo. In this connexion, two points of profound philosophical interest must be noted. The first is that, even in its fall, the Aristotelian influence survived, to some extent, both for good and for evil. To Aristotle belongs the merit of having been the first to base astronomy on physics. He maintains the earth��s immobility on experimental no less than on speculative grounds. A stone thrown straight up in the air returns to its starting-point instead of falling to the west of it; and the absence of stellar385 parallax seems to show that there is no change in our position relatively to the heavenly bodies. After satisfying himself, on empirical considerations, that the popular astronomy is true, he proceeds to show that it must be true, by considerations on the nature of matter and motion, which, although mistaken, are conceived in a genuinely scientific spirit. Now Galileo saw that, to establish the Copernican system, he must first grapple with the Peripatetic physics, and replace it by a new dynamical theory. This, which he could hardly have effected by the ordinary mathematical methods, he did by borrowing the analytical method of Atomism and applying it to the measurement of motion. The law of falling bodies was ascertained by resolving their descent into a series of moments, and determining its rate of velocity at successive intervals; and curvilinear motions were similarly resolved into the combination of an impulsive with an accelerating force, a method diametrically opposed to that of Bacon, who would not even accept the rough analysis of the apparent celestial motions proposed by Greek astronomers."Oh, you are a Netherlander; then come along."

TWO:Ever since the age of Parmenides and Heracleitus, Greek thought had been haunted by a pervading dualism which each system had in turn attempted to reconcile, with no better result than its reproduction under altered names. And speculation had latterly become still further perplexed by the question whether the antithetical couples supposed to divide all Nature between them could or could not be reduced to so many aspects of a single opposition. In the last chapter but one we showed that there were four such competing pairs��Being and Not-Being, the One and the Many, the Same and the Other, Rest and Motion. Plato employed his very subtlest dialectic in tracing out their connexions, readjusting their relationships, and diminishing the total number of terms which they involved. In what was probably his last great speculative effort, the Timaeus, he seems to have selected Sameness and Difference as the couple best adapted to bear the heaviest strain of thought. There is some reason for believing that in his spoken lectures he followed the Pythagorean system more closely, giving the preference to the One and the Many; or he may have employed the two expressions indifferently. The former would sooner commend itself to a dialectician, the latter to a mathematician. Aristotle was both, but he was before all things a naturalist. As such, the antithesis of Being and Not-Being, to which Plato attached little or no value, suited him best. Accordingly, he proceeds to work it out with a clearness before unknown in Greek philosophy. The first and surest of all principles, he declares, is, that a thing cannot both be and not be, in the same sense of the words, and furthermore that it must either be or not be. Subsequent340 logicians prefixed to these axioms another, declaring that whatever is is. The three together are known as the laws of Identity, Contradiction, and Excluded Middle. By all, except Hegelians, they are recognised as the highest laws of thought; and even Hegel was indebted to them, through Fichte, for the ground-plan of his entire system.235(1.) What change has taken place in the meaning of the name "invention" as applied to machine improvement?��(2.) What should precede an attempt to invent or improve machinery?��(3.) In what sense should the name invention be applied to the works of such men as Bentham, Bodmer, or Stephenson?

THREE:It has been alleged that civilians had been shooting from the Halls, but when a committee examined the remains in the building with the consent of the military, they found there the carcase of a German horse. They were ordered to stop their investigations immediately, for that horse was evidence ... that German military men had been billeted on the building, and thus no civilians could have been there. This will also be published later in the reports.
THREE:Among the many books published on the behaviour of the German Army in Belgium, this account by a distinguished Dutch journalist must occupy a unique place. It is written by a neutral, who held, at the start, no brief for either side. It is written by an eye-witness, who chronicles not what he heard, but what he saw. It is written also by one who mingled with the German troops and was present at the inception of the whole campaign of outrage. Mr. Mokveld took his life in his hands when, with great courage and devotion, he visited Vis�� and Li��ge and Louvain at the most critical moments. His character of neutral journalist was only a flimsy protection among the drunken and excited German troops. But his boldness was justified, for after many adventures he came safely through, and he was enabled in those early weeks to see the whole of Belgium from Li��ge to the Yser and from Antwerp to Dinant. The result is an admirable piece of war-correspondence, which bears on every page the proofs of shrewd observation and a sincere love of truth and honest dealing.The unhappy man asserted in a loud voice that183 he was innocent, but got the answer that he would have to prove that later on. But he never had a chance of doing that. Arriving at the market-place, he and three others were simply placed against the wall and shot. He could not even have spiritual assistance.
THREE:It may in the abstract be claimed that the dignity of any pursuit is or should be as the amount of good it confers, and the influence it exerts for the improvement of mankind. The social rank of those engaged in the various avocations of life has, in different countries and in different ages, been defined by various standards. Physical strength and courage, hereditary privilege, and other things that once recommended men for preferment, have in most countries passed away or are regarded as matters of but little importance, and the whole civilised world have agreed upon one common standard, that knowledge and its proper use shall be the highest and most honourable attainment to which people may aspire.
TWO:Another matter to be considered is that the engineering apprentice, in estimating what he will have to learn, must not lose sight of the fact that what qualifies an engineer of to-day will fall far short of the standard that another generation will fix, and of that period in which his practice will fall. This I mention because it will have much to do with the conceptions that a [9] learner will form of what he sees around him. To anticipate improvement and change is not only the highest power to which a mechanical engineer can hope to attain, but is the key to his success.

[160]"What!" Balmayne cried, "were you mad enough to----.""I know--I mean, what do I mean?" the Countess said hoarsely. "Really I don't know why I should be so interested."The inquest was sensational from the very start. After the dead man's landlady of the house by the docks and her landlord's agent proved the handwriting of the deceased, Sergeant Prout told the story of the missing banknotes. A good few of the packed audience knew Bruce by sight, and as the evidence proceeded he found the scrutiny of so many eyes quite trying.Jeff, peering, located the wing of the seaplane, the fuselage half submerged in muddy channel ooze, the tail caught on the matted eel-grass.
