... the ant-heap and the hive. This sense of the personal presence of an abiding Reality, fulfilling and transcending all our highest values, here in our space-time world of effort, may well be regarded as the differential mark of real spiritual experience, wherever found. It chimes well with the definition of Professor Pratt, who observes that the truly spiritual man, though he may not be any better morally than his non-religious neighbour, "has a confidence in the universe and an inner joy ...

... warmed earth could pass. In like manner, the sun's rays pass with comparative freedom through the aqueous vapour of the air: the absorbing power of this substance being mainly exerted upon the invisible heat that endeavours to escape from the earth. In consequence of this differential action upon solar and terrestrial heat, the mean temperature of our planet is higher than is due to its ...

... he had given himself up to higher mathematics when a young man, instead of turning his talent to account in an architect's office, a shipbuilding yard, or a locomotive shop. He could find the strain at any part of an iron frame building by the differential and integral calculus to the millionth of an ounce, but the everyday technical routine work with volumes of ready-made tables was unfamiliar and uncongenial to him; he would rather have calculated the tables themselves. The true science of mathematics is the ...

... explanation of the 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, driving the dust inward—at any ...

... important, but it was, on the whole, better calculated to startle the prevailing preconceptions; for, as to the new system of morals introduced by Christ, generally speaking, it is too dimly apprehended in its great differential features to allow of its miraculous character being adequately appreciated; one flagrant illustration of which is furnished by our experience in Affghanistan, where some officers, wishing to impress Akhbar Khan with the beauty of Christianity, very judiciously repeated to him the Lord's Prayer ...

His head was as solid as that of his father; which, instead of growing light, increased in specific, generic, and differential gravity, under circumstances which tend otherwise, with an age like ours, that insists upon sobriety, without allowing practice. All Springhaven folk had long practice in the art of keeping sober, and if ever a man walked with his legs outside his influence, it ...

... vortex theory as they interpret it. Our authors exhibit various reasons, more or less sound, for attributing to the primordial fluid some slight amount of friction; and in support of this view they adduce Le Sage's explanation of gravitation as a differential result of pressure, and Struve's theory of the partial absorption of light-rays by the ether,—questions with which our present purpose does not require us to meddle. Apart from such questions it is every way probable that the primary assumption of Helmholtz and Thomson is only ...

Nevertheless, although his venality was already more than suspected, and although his peculation, during his ...

... but 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 by the resistance of the worst. ...

Controversies raged about it.

... dualism may also be formulated as follows. If there are two Gods, they must have something in common—that in virtue of which they are Gods—and something in which they differ, which makes them two and not one. If each of them has in addition to divinity a differential element, they are both composite, and neither is the first cause or the necessary existent (19). If one of them only has this differentia, then this one is composite and is not ...

But it comes from British possessions, and is, therefore, sold here subject to a duty of only 18s. 8d. per cwt., whereas if it came from a foreign country it would pay 56s.[3] The differential duty drives the best cocoa out of the English market.

... "Baconian" method of observation and experiment, began to bear rich fruits. 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 invented logarithms, to shorten mathematical calculations.

... as the Divine power is cognizable to us, it falls exclusively within and never without the routine of Nature; and as universality is the characteristic of that routine, they do not hesitate, on behalf of science, to affirm that the Divine action is never addressed to specific or differential results, but always to universal or identical ones. In short, they logically refuse to the Divine power as exhibited in Nature all personal or moral quality, as inferring on the part of Deity any possible unequal or inequitable relations to the creatures He has made; and assign to all ...

... misinterpretation of Fabian doctrine it may be well to take 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 ...
