GRAVITATION, n. The tendency of all bodies to approach one another with a strength proportioned to the quantity of matter they contain-the quantity of matter they contain being ascertained by the strength of their tendency to approach one another. This is a lovely and edifying illustration of how science, having made A the proof of B, makes B the proof of A.
The laws of light and of heat translate each other;-so do the laws of sound and colour; and so galvanism, electricity and magnetism are varied forms of this selfsame energy.
We cannot step aside and say that we have achieved our goal by inventing a new drug or a new way by which to treat presently incurable diseases, a new way to help those who suffer from malnutrition, or the creation of ideal balanced diets on a worldwide scale. We cannot rest till the way has been found, with our help, to bring our finest achievement to everyone.
Two things fill the mind with ever new and increasing admiration and awe, the oftener and more steadily we reflect on them: the starry heavens above and the moral law within.
Poetry is not the proper antithesis to prose, but to science. Poetry is opposed to science, and prose to meter. The proper and immediate object of science is the acquirement, or communication of truth; the proper and immediate object of poetry is the communication of immediate pleasure.
There's nothing situate under heaven's eye But hath his bond in earth, in sea, in sky. The beasts, the fishes, and the winged fowls Are their males' subjects and at their controls. Man, more divine, the master of all these, Lord of the wide world and wild wat'ry seas, Indu'd with intellectual sense and souls, Of more pre-eminence than fish and fowls, Are masters to their females, and their lords; Then let your will attend on their accords.
That is another of your odd notions," said the Prefect, who had a fashion of calling every thing "odd" that was beyond his comprehension, and thus lived amid an absolute legion of "oddities.
Why are you so sure parallel lines exist? Believe nothing, merely because you have been told it, or because it is traditional, or because you have imagined it.
I was sitting in a chair in the patent office at Bern when all of a sudden a thought occurred to me: "If a person falls freely he will not feel his own weight." I was startled. This simple thought made a deep impression on me. It impelled me toward a theory of gravitation.
Creating a new theory is not like destroying an old barn and erecting a skyscraper in its place. It is rather like climbing a mountain, gaining new and wider views, discovering unexpected connections between our starting points and its rich environment. But the point from which we started out still exists and can be seen, although it appears smaller and forms a tiny part of our broad view gained by the mastery of the obstacles on our adventurous way up.
There rolls the deep where grew the tree. O earth, what changes hast thou seen! There where the long street roars, hath been The stillness of the central sea. The hills are shadows, and they flow From form to form, and nothing stands; They melt like mist, the solid lands, Like clouds they shape themselves and go.
