Page 155 - 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.
Page 133 - Every body continues in its state of rest or of uniform motion in a straight line, except in so far as it may be compelled by impressed forces to change that state.
Page 139 - To every action there is always an equal and contrary reaction ; or the mutual actions of any two bodies are always equal and oppositely directed.
Page 134 - Change of motion is proportional to the impressed force, and takes place in the direction of the straight line in which the force is impressed.
Page 55 - We cannot, of course, give a definition of Matter which will satisfy the metaphysician; but the naturalist may be content to know matter as that which can be perceived by the senses, or as that which can be acted upon by, or can exert, force. The latter, and indeed the former also, of these definitions involves the idea of Force, which, in point of fact, is a direct object of sense ; probably of all our senses, and certainly of the
Page 78 - It is abundantly clear that if the so-called elements, or more properly speaking their finest atoms — those that give us line spectra — are really compounds, the compounds must have been formed at a very high temperature. It is easy to imagine that there may be no superior limit to temperature, and therefore no superior limit beyond which such combinations are possible...
Page 77 - Moreover, there is reason to suspect that the so-called simple substances are themselves compound ; and that there is but one ultimate form of Matter, out of which the successively-more complex forms of Matter are built up. By the different grouping of units, and by the combination of the unlike groups each with its own kind and each with other kinds, it is supposed that there have been produced the kinds of matter we call elementary ; just...
Page 125 - It is therefore unscientific to distinguish between rest and motion, as between two different states of a body in itself, since it is impossible to speak of a body being at rest or in motion, except with reference expressed or implied, to some other body.
Page 125 - If, when referred to a certain point, the body appears to be moving northward with diminishing velocity, we have only to refer it to another point moving northward with a uniform velocity greater than that of the body, and it will appear to be moving southward with increasing velocity.
Page 56 - These introductory remarks have been brought in with the view of warning the reader that we are dealing with a subject so imperfectly known that at almost any part of it we may pass, by a single step as it were, from what is acquired certainty to what is still subject for mere conjecture. An exact or adequate conception of matter itself, could we obtain it, would almost certainly be something extremely unlike any conception of it which our senses and our reason will ever enable us to form.
