45. oldal - How these attractions may be performed, I do not here consider. What I call 'attraction' may be performed by impulse, or by some other means unknown to me. I use that word here to signify only in general any force by which bodies tend toward one another, whatsoever be the cause.
142. oldal - I cannot help thinking while I dwell upon them, that this discovery of magneto-electricity is the greatest experimental result ever obtained by an investigator. It is the Mont Blanc of Faraday's own achievements. He always worked at great elevations, but a higher than this he never subsequently attained.
28. oldal - They should ever be held as doubtful, and liable to error and to change ; but they are wonderful aids in the hands of the experimentalist and mathematician. For not only are they useful in rendering the vague idea more clear for the time, giving it something like A definite shape, that it may be submitted to experiment and calculation ; but they lead on, by deduction and correction, to the discovery of new phenomena, and so cause an increase and advance of real physical truth, which, unlike the hypothesis...
27. oldal - Two-thirds of the rays emitted by the sun fail to arouse in the eye the sense of vision. The rays exist, but the visual organ requisite for their translation into light does not exist. And so from this region of darkness and mystery which surrounds us, rays may now be darting which require but the development of the proper intellectual organs to translate them into knowledge as far surpassing ours as ours...
11. oldal - For there is a certain real limit of causes in nature, and it would argue levity and inexperience in a philosopher to require or imagine a cause for the last and positive power and law of nature, as much as it would not to demand a cause in those that are subordinate.
55. oldal - But since the uttermost limit of Being is ended and perfect, Then it is like to the bulk of a sphere well-rounded on all sides, Everywhere distant alike from the centre; for never there can be Anything greater or anything less, on this side or that side; Yea, there is neither a non-existent to bar it from coming Into equality, neither can Being be different from Being, More of it here, less there, for the All is inviolate ever.
83. oldal - ... same coast of heaven in the building that they lay in the mine. The same is of plants removed, if they be coasted just as they were before. Observations. (1.) Let this be laid for a foundation, which is most sure, that there is in every tangible body a spirit, or body pneumatical, enclosed and covered with the tangible parts...
104. oldal - ... to these causes. I do not pledge myself to this theory, nor do I ask you to accept it as demonstrated ; still it would be a great mistake to regard it as chimerical. It is a noble speculation ; and depend upon it, the true theory, if this, or some form of it, be not the true one, will not appear less wild or less astounding.* Mayer published his Essay in 1848 ; five years afterwards Mr.
141. oldal - force "is understood by many to mean simply " the tendency of a body to pass from one place to another...
131. oldal - Newton generalized the law of attraction into a statement that every particle of matter in the universe attracts every other particle with a force which varies directly as the product of their masses and inversely as the square of the distance between them; and he thence deduced the law of attraction for spherical shells of constant density.
