الصفحة 14 - And therefore, that nature may be lasting, the changes of corporeal things are to be placed only in the various separations and new associations and motions of these permanent particles; compound bodies being apt to break not in the midst of solid particles, but where those particles are laid together and only touch in a few points.
الصفحة 3 - In this we are naturally led to the consideration of the curvature and tortuosity of curves, the curvature of surfaces, and various other purely geometrical subjects. ***** "Chapter II. gives NEWTON'S Laws of Motion in his own words, and with some of his own commentaries ; every attempt that has yet been made to supersede them having ended in utter failure. "Chapter III. briefly treats of Observation and Experiment as the basis of Natural Philosophy. " Chapter IV. deals with the fundamental Units,...
الصفحة 69 - I am characterising as delusive, while in reality those improvements are the fruit of painstaking, but incorrectly rationalised, experience. I am but insisting on views which the highest mathematicians of the day have established irrefutably ; and my work has been to appreciate and adapt these views when presented to me.* No one is more alive than myself to the plausibility of the unsound views against which I am contending ; but it is for the very reason that they are so plausible that it is necessary...
الصفحة 42 - ... much to hope that future observation, borrowing every aid from rational speculation, grounded on the progress of physical science generally (especially those branches of it which relate to the...
الصفحة 13 - And against filling the heavens with fluid mediums, unless they be exceeding rare, a great objection arises from the regular and very lasting motions of the planets and comets in all manner of courses through the heavens. For thence it is manifest that the heavens are void of all sensible resistance, and by consequence of all sensible matter.
الصفحة 4 - The Elements: an. Investigation of the Forces which determine the Position and Movements of the Ocean and Atmosphere.
الصفحة 42 - In no respect is the question as to the materiality of the tail more forcibly pressed on us for consideration, than in that of the enormous sweep which it makes round the sun in perihelio, in the manner of a straight and rigid rod, in defiance of the law of gravitation, nay, even of the received laws of motion...
الصفحة 68 - ... for estimating the resistance of bodies moving through water were not only wrong in detail, but that the supposed cause of resistance, with which alone they professed to be dealing, was in reality no cause at all; and that the real cause of resistance, whatever it might be, was entirely left out. It is easy to imagine how fruitful, in false aims and false principles of nautical construction, would be the assignment of the resistance of ships to a supposed cause which has no existence at all.
الصفحة 69 - FIG. 23. same length, and the same sharpness of ends as the other, but is filled out amidships to a larger cross section. On the midship section theory, this one would clearly have the greatest resistance of the two. Nevertheless, in the trial of two models of those lines it appeared that at the higher speeds, the form with the largest cross section made considerably the least resistance.
الصفحة 69 - ... amidships to a larger cross section. On the midship section theory, this one would clearly have the greatest resistance of the two. Nevertheless, in the trial of two models of those lines it appeared that at the higher speeds, the form with the largest cross section made considerably the least resistance. The explanation of this lies of course in the fact that the addition amidships, though increasing the displacement, forms a prolongation of the wave features of the two ends, and thus lessens...
