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.
One might talk about the sanity of the atom the sanity of space the sanity of the electron the sanity of water- For it is all alive and has something comparable to that which we call sanity in ourselves. The only oneness is the oneness of sanity.
Chlorine is a deadly poison gas employed on European battlefields in World War I. Sodium is a corrosive metal which burns upon contact with water. Together they make a placid and unpoisonous material, table salt. Why each of these substances has the properties it does is a subject called chemistry.
Not from the stars do I my judgement pluck, And yet methinks I have astronomy. But not to tell of good or evil luck, Of plagues, of dearths, or season's quality; Nor can I fortune to brief minutes tell ... Or say with princes if it shall go well.
Invention breeds invention. No sooner is the electric telegraph devised than gutta-percha, the very material it requires, is found. The aeronaut is provided with gun-cotton, the very fuel he wants for his balloon.
The universal and lasting establishment of peace constitutes not merely a part, but the whole final purpose and end of the science of right as viewed within the limits of reason.
Some of the scientists, I believe, haven't they been changing their opinion a little bit on global warming? There's a lot of differing opinions and before we react I think it's best to have the full accounting, full understanding of what's taking place.
The supreme task of the physicist is to arrive at those universal elementary laws from which the cosmos can be built up by pure deduction. There is no logical path to these laws; only intuition, resting on sympathetic understanding of experience, can reach them.
At no period of [Michael Faraday's] unmatched career was he interested in utility. He was absorbed in disentangling the riddles of the universe, at first chemical riddles, in later periods, physical riddles. As far as he cared, the question of utility was never raised. Any suspicion of utility would have restricted his restless curiosity. In the end, utility resulted, but it was never a criterion to which his ceaseless experimentation could be subjected.
But what is classification but the perceiving that these objects are not chaotic, and are not foreign, but have a law which is also the law of the human mind?
