... young De Saussure, grandson of the naturalist of that name, who, the first with a single exception, reached the summit of Mont Blanc. The subject of our lecture was some puzzling proposition in the differential calculus, and De Saussure propounded to the professor a knotty difficulty in connection with it. The professor replied unsatisfactorily. My friend still pressed his point, and the professor rejoined very learnedly and ingeniously, ...

... worn-out boxes, shaky foundations, and uneven tables, sometimes with the plates not half amalgamated, or coated with impurities, the whole concern superintended by a man who knows as little about the treatment of auriferous quartz by the amalgamating or any other processes as a dingo does of the differential calculus. Result: 3 dwt. to the ton in the retort, 30 dwt. in the tailings, and a payable ...

... basis of our present findings it is no longer enough to trace the appearing of the after-image solely to a differential fatigue in the retina. The fact is that as long as the eye is turned to the bright window-pane a more intensive blood-activity occurs in the portions of the eye's background met by the light than in those where the dark window-bar throws its shadow on the ...
— Man or Matter • Ernst Lehrs
... with respect to their subjects, may be divided into the speculative, the practical, and such as are of a mixed nature. The subjects of these last are either general, comprehending both the others; or differential, distinguishing them. The general subject are either fundamental, or final: those of the fundamental kind are philosophy, human nature, the soul of man; of the final kind are love, beauty, good. The differential regard knowledge, as it stands ...
— Introduction to the Philosophy and Writings of Plato • Thomas Taylor
... own existence. The 'objections,' as he puts it, are only 'difficulties'; they make it hard to understand the theory, but are no more reasons for rejecting it than would be the difficulty which a non-mathematical mind finds in understanding the differential calculus for rejecting 'Taylor's theorem.' And, so far, the difference is rather in the process than the conclusion. Newman believes in God on the testimony of an inner voice, so conclusive and imperative that he can dismiss all apparently contradictory facts, and even afford, for controversial ...

... maintained, that with time and patience, one might train a rather stupid plough-boy to understand the differential calculus. This might be done with the help of an inward desire on the part of the boy to learn, but never otherwise. If the boy wants to learn or to improve generally, he will do so in spite of every hindrance, till in time he becomes a very different being from what he ...
— Life and Habit • Samuel Butler
... consider it were more fitting to place the present species in a distinct genus, as Polyporus is set off from Hydnum. A species based upon the color of the vegetative phase only, unconfirmed by any subsequent differential character in the fruit would seem somewhat hazardous. The color of the plasmodium is incident probably to varied nutrient environment. Pores, however, are ...

... piece, with a variation which is immense in its range, but fairly continuous in its gradation. These are thus two aspects from which the phenomena of price and rent can be regarded; aspects which it is usual to call, (1) the scarcity aspect, (2) the differential aspect. ...
— Supply and Demand • Hubert D. Henderson
... the country amounted, in round figures, to about L5,000,000 sterling in imports, and somewhat less in exports The imports were chiefly manufactures from Great Britain, and the exports were lumber, wheat and fish. Those were days when colonial trade was stimulated by differential duties in favour of colonial products, and the building of vessels was encouraged by the old navigation laws which shut out foreign commerce from the St. Lawrence and the Atlantic ports, and kept the carrying trade between Great Britain and the colonies in the ...
— Canada under British Rule 1760-1900 • John G. Bourinot
... this opportunity of refuting the error. He says that Fabianism advocates the socialisation of rent, and in confirmation quotes Shaw's words "rent and interest"! That makes all the difference. If the term rent is widened to include all differential unearned incomes, from land, from ability, from opportunity (i.e. special profits), interest includes all non-differential unearned incomes, and thus the State is to be endowed, not with rents alone, but with all unearned incomes.[52] It is true that the Fabians, ...

... to lights extinguished, and that it compensates for speed variations above the minimum speed. The manner of its action is to control the generation of current at the source in the armature, and it does so by combining certain electrical actions so as to obtain a differential effect, such that when small force of current only is required it alone is furnished, and when the maximum force is needed the ...

... Leibnitz mentioned in a letter to Oldenburg (to be communicated to Newton) that he had been for some time in possession of a method for drawing tangents, and explains the method, which was no other than the differential calculus. Before Newton had published a single word upon fluxions the differential calculus had made rapid advances on ...

... the penultimate hundred yards were covered with fixed bayonets. In this manner we were prepared for any surprise. The enemy replied fitfully to our fire, and we could now see several khaki-clad figures with white hat-bands—the differential symbols—moving backwards and forwards amidst the trees. Presently they disappeared as we worked nearer to their lines. We were now rushing forward, lying down to fire, rising and running only to drop down ...

... foot, or even better weapons, would often lead to victory as well as mere physical strength. Moreover, this kind of more or less perpetual war goes on amongst savage peoples. It could lead, therefore, to no differential characters, but merely to the keeping up of a certain average standard of bodily ...

... obstructing his study, was in reality an aid to his thinking and a spur to excellence—not excellence over others, but over himself. There were moments, doubtless, long moments too, in which he forgot Homer and Cicero and differential calculus and chemistry, for "the bonnie lady-lassie,"—that was what he called her to himself; but it was only, on emerging from the reverie, to attack his work with fresh vigour. She was so young, so plainly girlish, ...

... cylinder heads, and adjust cams, and spend hours knocking everything to pieces and putting them together again so that I might be prepared for getting on without him. He said he hated to think of that time, and what do you suppose he did? I was lying under the machine at the time, studying the differential, while he was jacking up an axle. Proposed, positively. I dropped a nut and a cotter pin out of my mouth, I was so astonished. We talked it over for about five minutes through one of the artillery, wheels, and I must say he took it beautifully. I wanted to be nice to him, because he had been so patient ...

... Challis—and at the mention of that conversation his brows drew together and he became very grave again; "but in the course of that conversation this child had occasion to refer, by way of illustration, to some abstruse theorem of the differential calculus. He did it, you will understand, by way of making his meaning clear—though the illustration was utterly beyond me: that reference represented an ...

... start the engine in the morning, and the same number to persuade her to leave off firing at night. The works manager, Mr. Nathan, whose Christian name was Abraham, said that she'd done eighty miles an hour with him easily; but the only time I got her over fifty she broke her differential by way of an argument, and nothing but a soft place in a hayfield saved me from the hospital. All of which, of course, was good advertisement for the firm—and, truly, if it came to making a noise in the world, why, you could hear their car a good quarter ...

... York and Chicago, the two best equipped roads charge a fare of twenty dollars on their ordinary, and a higher rate on their limited, trains. Because of slower time the other roads charge a sum less by two or three dollars for the same service. This cut in the rate is called a "differential." ...

... components which pass together to one pole. Examples of this are Syromaster, Phylloxera, Agalena. In a third class the sex-chromosome is accompanied by a fellow which is usually smaller, and the two separate at the differential division. The sizes of the two differ in different degrees, from cases as in many Coleoptera and Diptera in which the smaller chromosome is very minute, to those (Benacus, Mineus) in which it is almost as ...

... ISAAC (1642-1727).—Natural philosopher, b. at Woolsthorpe, Lincolnshire, the s. of a small landed proprietor, and ed. at the Grammar School of Grantham and at Trinity Coll., Camb. By propounding the binomial theorem, the differential calculus, and the integral calculus, he began in 1665 the wonderful series of discoveries in pure mathematics, optics, and physics, which place him in the first rank of the philosophers of all time. He was elected Lucasian Prof. of Mathematics at ...

... concerned mainly Great Britain. Presumably it was profitable on both sides, for all trade is barter. In any event, Great Britain has never raised a tariff wall against it, never protected her traders by a single differential duty. She has risen above the idea that by tariff exactions the foreigners can be made to pay the sages. As for envy of German commerce, who ever heard of an ...

... is said to be equally versed in Law, Physic, and Divinity, to sport with trigonometry, and to amuse his lighter moments with the differential calculus. But "this knowledge was too wonderful for him, he could not attain unto it," and to avoid confession of defeat, he fled with lightning speed. This erudite doctor is well known in England, especially among riflemen. Colonel Saunderson describes him as a wonderful shot at a thousand ...

... I've always admitted that you were simply perfect,' Harry said, glancing at her with visible admiration, 'and I don't think anything on earth could possibly improve you—except perhaps a judicious course of differential and integral calculus, which might possibly serve to tone down slightly your exuberant and excessive vitality. Still, you know, from the point of view of society, which is a force we have always to reckon with—a constant, in fact, that we may call Pi—there can ...

... remarkable muscular strength and skill in managing herself in the accomplishment of feats which looked impossible at first sight. How often The Terror had thought to herself that she would gladly give up all her knowledge of Greek and the differential and integral calculus if she could only perform the least of those feats which were mere play to The Wonder! Miss Euthymia was not behind the rest in her attainments in classical or mathematical knowledge, and she was one of the very best students in the out-door ...

... retiring, an estated squire-arch, to the otium cum., or sine dignitate, as the case might be, of a country life; and this disposition had of late been much quickened by daily-increasing apprehensions of negro emancipation and revolutionary interference with differential duties—changes which, in conjunction with others of similar character, would infallibly bring about that utter commercial ruin which Mr. Linden, like every other rich and about-to-retire merchant or tradesman whom I have ever known, constantly prophesied ...

... used by the creature in laying its eggs, we should then have, with the spring, an additional point of resemblance to the Neuroptera and higher insects, and instead of this spring being an important differential character, separating the Thysanura from other insects, it binds them still closer, though still differing greatly in representing only a part of the ovipositor of the higher insects. (This is a catch for ...

... was told to come, and sat down to a stock of foolscap, and had a pretty stiff exam. I am only just through. I had seamanship, gunnery, navigation, nautical astronomy, algebra, geometry, trigonometry, conic sections, curve tracing, differential and integral calculus. I had only three questions out of five to answer in each branch, but in the first three I answered all five. After that I only had time for three, but at the end he said I need not finish, he was perfectly satisfied. I had done remarkably well, and he would report ...
— Real Soldiers of Fortune • Richard Harding Davis
... Australians, a somewhat different complexion is put upon the state of their culture. With very plain living went something that approached to high thinking; and we must recognize in this case, as in others, what might be termed a differential evolution of culture, according to which some elements may advance, whilst others stand ...

... considerable social usefulness—and that it grades off almost imperceptibly into dementia praecox. The features differentiating these two diseases should therefore supply us with data for determining the prognosis. A case undoubtedly, praecox, which shows markedly the differential features of paranoia, should have a proportionately better outlook. In a vague way our common sense uses this standard when it makes us "feel" that the case will have a long course which shows a relatively ...

... midst of cruel sufferings, a method which embraced all the problems—a method founded upon the summation of certain series, of which he had given the elements in his writings accompanying his ‘Traité du Triangle Arithmétique.’ From this discovery there was only a step to that of the Differential and Integral Calculus; and it may be confidently presumed that, if Pascal had proceeded with his mathematical studies, he would have anticipated Leibnitz and Newton in the ...

... the far end of a telescope. Sainte-Beuve, as he grew older, came to regard all experience as a single great book, in which to study for a few years ere we go hence; and it seemed all one to him whether you should read in Chapter xx., which is the differential calculus, or in Chapter xxxix., which is hearing the band play in the gardens. As a matter of fact, an intelligent person, looking out of his eyes and hearkening in his ears, with a smile on his face all the time, will get more ...

... magnitude on February 22, 1901. This "star," the paper tells us, when studied by its spectrum, is seen to be due to the impact of two swarms of meteors out in space—swarms moving in different directions "with a differential velocity of something like seven hundred miles a second." Every astronomer of to-day understands how such a record is read from the displacement of lines on the spectrum, as recorded on the photographic negative. But imagine ...

... his scholars; for it is not this faculty which made him their ideal, however it may have attracted them. All which sensible men deplore in him is that which poetasters have exalted in him. His morbidity and his doubt have become in their eyes his differential energy, because too often, it was all in him with which they had wit to sympathise. They found it easy to curse and complain, instead of helping to mend. So had he. They found it pleasant to confound institutions ...

... of this difficulty in unweaving the maze, has its source in a misconception of the original machinery by which Christianity moved, and of the initial principle which constituted its differential power. In books, at least, I have observed one capital blunder upon the relations which Christianity bears to Paganism: and out of that one mistake, grows a liability to others, upon the possible relations of Christianity to the total drama of this world. I will endeavor to explain my views. ...

How many creators have been wrecked because the conditions necessary for their inventions were lacking? Roger Bacon foresaw several of our great discoveries; Cardan, the differential calculus; Van Helmont, chemistry; and it has been possible to write a book on the forerunners of Darwin.[71] We talk so much of the free flight of imagination, of the all-comprehensive power of the creator, that ...

... good fortune to divine the future course of piano development, as also did Schumann. Both took for the strategic center of the piano the principle of what has been called the "differential touch," or discrimination in touch, by means of which not only long passages of different kinds were discriminated from one another, as in the Thalbergian melodies and their surrounding arabesques, but the infinitely finer discriminations which ...

... national sense perhaps much more than the individual. We shall take it for granted that British and Irish products and manufactures enjoy a preference on import into the colonies, over imports from foreign countries, of at least five per cent, resulting from differential duties in favour of the parent state: it may be more, and we believe it will be found more; but such is the preference. This profit must be all to the account of the British exporter; for it is not received by the colonial custom-house, and whatever the reduction ...

... doctrine of the nature of space which is not in essence inherent in the theory of the relativity of space. But this doctrine has never really been accepted in science, whatever people say. What appears in our dynamical treatises is Newton's doctrine of relative motion based on the doctrine of differential motion in absolute space. When you once admit that the points are radically different entities for differing assumptions of rest, then the orthodox formulae lose all their obviousness. They were only obvious because you were really thinking of something else. When ...

... so wasted as they seem to have been. Not only Functions of a Quaternion, but other of these books, chatty books about hydro-mechanics and dynamics of a particle (no, not an article—that might have been helpful—a particle), gossipy books about optics and differential equations, many of these have a comforting air of cleanness; as if, having bought them at the instigation of my instructor, I had felt that this was enough, and that their mere presence in my bookcase ...
