adjective
differential  adj.  
1.
Relating to or indicating a difference; creating a difference; discriminating; special; as, differential characteristics; differential duties; a differential rate. "For whom he produced differential favors."
2.
(Math.) Of or pertaining to a differential, or to differentials.
3.
(Mech.) Relating to differences of motion or leverage; producing effects by such differences; said of mechanism.
Differential calculus. (Math.) See under Calculus.
Differential coefficient, the limit of the ratio of the increment of a function of a variable to the increment of the variable itself, when these increments are made indefinitely small.
Differential coupling, a form of slip coupling used in light machinery to regulate at pleasure the velocity of the connected shaft.
Differential duties (Polit. Econ.), duties which are not imposed equally upon the same products imported from different countries.
Differential galvanometer (Elec.), a galvanometer having two coils or circuits, usually equal, through which currents passing in opposite directions are measured by the difference of their effect upon the needle.
Differential gearing, a train of toothed wheels, usually an epicyclic train, so arranged as to constitute a differential motion.
Differential motion, a mechanism in which a simple differential combination produces such a change of motion or force as would, with ordinary compound arrangements, require a considerable train of parts. It is used for overcoming great resistance or producing very slow or very rapid motion.
Differential pulley. (Mach.)
(a)
A portable hoisting apparatus, the same in principle as the differential windlass.
(b)

Differential screw, a compound screw by which a motion is produced equal to the difference of the motions of the component screws.
Differential thermometer, a thermometer usually with a U-shaped tube terminating in two air bulbs, and containing a colored liquid, used for indicating the difference between the temperatures to which the two bulbs are exposed, by the change of position of the colored fluid, in consequence of the different expansions of the air in the bulbs. A graduated scale is attached to one leg of the tube.
Differential windlass, or Chinese windlass, a windlass whose barrel has two parts of different diameters. The hoisting rope winds upon one part as it unwinds from the other, and a pulley sustaining the weight to be lifted hangs in the bight of the rope. It is an ancient example of a differential motion.

... the proper distance. In the counter contrived by Mr. Adie, an endless screw works into the rim of two small wheels situated on the same axis, but one wheel having a tooth more than the other, whereby a differential motion is obtained; and the difference in the velocity of the two wheels, or their motion upon one another, expresses the number of strokes performed. The endless screw is attached to some revolving part of the engine, whereby a rotatory motion is imparted to it; and ...

... containing many of the best observations of the ancients on human nature and life, my father made me study with peculiar care, and throw the matter of it into synoptic tables. During the same years I learnt elementary geometry and algebra thoroughly, the differential calculus, and other portions of the higher mathematics far from thoroughly: for my father, not having kept up this part of his early acquired knowledge, could not spare time to qualify himself for removing my difficulties, and left me to deal with them, with little other aid than that of books: ...

... Edie, 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 ...

... 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 take place within ...

Sir Isaac Newton (1642-1727) not only discovered the law of gravitation: other discoveries by him in mechanics and optics were of great moment in the progress of those sciences. Fluxions, or the differential calculus, was discovered independently by both Newton and Leibnitz. Euler, a Swiss mathematician of the highest ability (1707-1783), contributed essentially to the advancement of mechanics. Napier ...

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 Sir William Herschel, roused from a century's ...

... his profound vision perceived its possible invalidity. He saw that it was at least possible that the difference of conducting power between the earth and the wire might give one an advantage over the other, and that thus a residual or differential current might be obtained. He combined wires of different materials, and caused them to act in opposition to each other, but found the combination ineffectual. The more copious flow in the better conductor was exactly counterbalanced ...

The long lines of escarpment which often stretch for miles across country, are now ascertained, mainly through the researches of Whitaker, to be due to the differential action of aerial causes. The general origin of mountain chains, however, was at first naturally enough attributed to direct upward pressure from below. To attribute them in any way to subsidence seems almost a paradox, and yet it ...

... propagandists pointed out to them that the French worker was paid 100 per cent. more, they brooded over the inequality and labeled it as they were told. For overwork, too, the rate of pay was still more unequal. One result of this differential treatment was the estrangement of the two races as represented by the two classes of workmen, and the growth of mutual dislike. But there was another. When they learned, as they did in time, that the employer ...

... trustee of Irish interests. But nobody of this generation ever knew a Chancellor of the Exchequer who had even read the Act of Union; Mr Lloyd George, on his own admission, had certainly not read it in 1909. What has happened is very simple. The fulfilment of treaty obligations required differential taxation, but administrative convenience was best served by a uniform system of taxation. In the struggle between the two, conscience was as usual defeated. The Chancellor, according to the practice which has overridden the Act of Union budgets for Great Britain, drags the schedule ...

... 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 of prices ...

Now, I want you to dig Sophy; a Sanscrit, or a Hindostanee, or a Persian treasure will do equally well as a pretext. If she had announced a taste for the differential calculus, I should have said the same. Only dig her, as Maurice dug me apropos to Homer. I wouldn't bother you, only you see no one else could either do it, or ...

... dust free spaces in a few words, but we may say roughly that there is a molecular bombardment from all warm surfaces by means of which small suspended bodies get driven outward and kept away from the surface. It is a sort of differential bombardment of the gas molecules on the two faces of a dust particle somewhat analogous to the action on Mr. Crookes' radiometer vanes. Near cold surfaces the bombardment is very feeble, and if they are cold enough it appears to act toward the body, ...

There is a tendency among the employees to keep a close watch on the wages paid to other groups of their fellow workmen, and the differential between their wage and that of some other grade of employment is jealously guarded. Thus on the railways, wage increases usually advance in cycles, an advance to engineers being followed at a close ...

... '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.'

No one could maintain such a position who grasped the doctrines of continuity and of the differential calculus." It seems to me that even without the help of the differential calculus, we can, with the help of logic and grammar, put a stop to this argument. Boy is the subject, stature looks like a subject, but is merely a predicate, and should ...

But now Jesus Christ hath put a new stamp and signification on it; and made it the very differential character and token of his disciples, "By this shall all men know that ye are my disciples, if ye love one another." And therefore, when he is making his latter will, he gives this testamentary commandment to his children and heirs, "A new commandment give I unto ...

... only concur, but 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, ...

... steam is turned on at the boiler it flows through the steam pipe and governor, entering the compressor at the steam enlet, then through the steam passage "a" to the reversing valve chamber "C" also to the main valve chamber "A" between the differential pistons 77 and 79. The area of the piston at the right being greater than the one at the left, the main valve is moved to the right, (See Fig. 2) admitting steam to port "b" which leads to the lower end of the steam cylinder; steam is now free to flow under the main piston, forcing ...

... opinion that we should hesitate before adopting that interpretation in view of the cogent indirect evidence afforded by other data that the fall of the birth-rate is differential, and that the differentiation is largely economic. There are at least two considerations which must be borne in mind in connection with these schedules. The first is, that all the marriages described as unlimited may not have been so. I do not suggest that the answers are intentionally ...

... 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 ...

... of Russia. We have actually succeeded in wringing from the tenacious and inflexible Cabinet of St Petersburg an important commercial advantage! On Lord Aberdeen's accession to office, he found Russia in the act of aiming a fatal blow at a very important branch of our shipping trade, by levying a differential duty on all British vessels conveying to Russian ports any goods which were not the produce of the British dominions. After, however, a skilful and very arduous negotiation, our foreign secretary has succeeded ...

A man doesn't want to talk politics to his wife, and what do you think I care for Betty's views upon the Differential Calculus? A man wants a wife who can cook his dinner and look after his children. I've tried both and I know. Let's ...

... In the following year 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 ...

The differential coA"fficient has yet to be determined which shall express the developmental changes in two variables at once. When, therefore, we attempt to extend the formulA| of differentiation to plant and animal ...

... second class of cases the sex-chromosome is double, consisting of two 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 large as its fellow, and ...

Unblocking decisions even for adults are usually based on suitability of the Web ...

To these we find nothing analogous in the other kingdoms, though the poorer classes of Welsh freemen had wergilds varying from 120 to 60 shillings. It should be added that the differential treatment of the various classes was by no means confined to the case of wergilds. We find it also in the compensations to which they were entitled for various injuries, in the fines to which they were liable, and in the value attached ...
