الصفحة 113 - that every particle of matter in the universe attracts every other particle, with a force whose direction is that of the line joining the two, and whose magnitude is directly as the product of their masses, and inversely as the square of their distances from each other.
الصفحة 135 - That gravity should be innate, inherent, and essential to matter, so that one body may act upon another at a distance through a vacuum, without the mediation of anything else, by and through which their action and force may be conveyed from one to another, is to me so great an absurdity that I believe no man who has in philosophical matters a competent faculty of thinking can ever fall into it. Gravity must be caused by an agent acting constantly according to certain laws, but whether this agent...
الصفحة 3 - ... to derive two or three general principles of motion from phenomena, and afterwards to tell us how the properties and actions of all corporeal things follow from those manifest principles, would be a very great step in philosophy, though the causes of those principles were not yet discovered...
الصفحة 161 - A Defence of the Doctrine touching the spring and weight of the air ... against the objections of Franciscus Linus, etc.
الصفحة 135 - It is inconceivable that inanimate brute matter should without the mediation of something else, which is not material, operate upon and affect other matter without mutual contact, as it must be if gravitation, in the sense of Epicurus, be essential and inherent in it.
الصفحة 135 - You sometimes speak of gravity as essential and inherent to matter. Pray do not ascribe that notion to me; for the cause of gravity is what I do not pretend to know, and therefore would take more time to consider of it.
الصفحة 204 - ... the power of any spring is in the same proportion with the tension thereof: that is, if one power stretch or bend it one space, two will bend it two, and three will bend it three, and so forward.
الصفحة 302 - Spencer records his conviction that 'the chemical atoms are produced from the true or physical atoms by processes of evolution under conditions which chemistry has not yet been able to produce.
الصفحة 102 - The rate of change of momentum is proportional to the impressed force, and takes place in the direction in which the force acts.
الصفحة 325 - ... mercurial cylinder in the longer leg that compressed the air into those dimensions. C. The height of the mercurial cylinder that counterbalanced the pressure of the atmosphere. D. The aggregate of the two last columns, B and C, exhibiting the pressure sustained by the included air. E. What that pressure should be according to the hypothesis that supposes the pressures and expansions to be in reciprocal proportion.
