In the interior of the atom, Bohr had tried the plan of retaining the particle-electron and modifying the classical mechanics. Heisenberg took the opposite course, his procedure amounting in effect to retaining the classical mechanics, at least in form, and modifying the electron. Actually, the electron dropped out all together, because it exists only as a matter of inference and not of direct observation. For the same reason, the new theory contains no mention of atoms, nuclei, protons, or of electricity in any shape or form. The existences of all these are matters of inference, and Heisenberg's purely mathematical theory could no more make contact with them than with the efficiency of a turbine or with the price of wheat.

I had translated the first twelve books of the Odyssey. For a while I learnt English also, merely so as to gain an accurate knowledge of Shakespeare; and I made a metrical translation of Romeo's monologue. Though I soon left English on one side, yet Shakespeare remained my exemplar, and I projected a great tragedy which was almost nothing but a medley of Hamlet and King Lear. The plan was gigantic in the extreme; two- and-forty human beings died in the course of this piece, and I saw myself compelled, in its working-out, to call the greater number back as ghosts, since otherwise I should have been short of characters for my last Acts. This play occupied my leisure for two whole years.
Richard Wagner
God has permitted and does permit us to be shaken by adversity. Difficult times lie ahead. We will be greatly tested. We have to take this warning seriously and live spiritually... Many saints would have loved to have lived in our times and have had our chance to struggle for Christ... Our struggle matters because it is not a struggle against an Ali Pasha, or a Hitler and a Mussolini, but a struggle against the devil himself. For this reason, our wages will be heavenly... The saints will become more holy and the vile will become more vile. Yet I feel great consolation inside. This is only a storm; like past storms, it will pass. May the Good God take evil and turn it into good. Amen.
Paisios of Mount Athos
As we walked homeward across the fields, the sun dropped and lay like a great golden globe in the low west. While it hung there, the moon rose in the east, as big as a cart-wheel, pale silver and streaked with rose colour, thin as a bubble or a ghost-moon. For five, perhaps ten minutes, the two luminaries confronted each other across the level land, resting on opposite edges of the world.
In that singular light every little tree and shock of wheat, every sunflower stalk and clump of snow-on-the-mountain, drew itself up high and pointed; the very clods and furrows in the fields seemed to stand up sharply. I felt the old pull of the earth, the solemn magic that comes out of those fields at nightfall. I wished I could be a little boy again, and that my way could end there.
Willa Cather
The idea that our natural resources were inexhaustible still obtained, and there was as yet no real knowledge of their extent and condition. The relation of the conservation of natural resources to the problems of National welfare and National efficiency had not yet dawned on the public mind. The reclamation of arid public lands in the West was still a matter for private enterprise alone; and our magnificent river system, with its superb possibilities for public usefulness, was dealt with by the National Government not as a unit, but as a disconnected series of pork-barrel problems, whose only real interest was in their effect on the reëlection or defeat of a Congressman here and there-a theory which, I regret to say, still obtains.
Theodore Roosevelt
What is very important to me is two points: A theory should be internally consistent and it should have some contact with observation. Well, I'm told by all the experts that this theory [String theory] is internally consistent, although they think up new interpretations every time I turn my back. But contact with reality? Nobody's given me anything. I just watch. I'm somewhat unhappy that so many people are working on it. To me, as a physicist, it's sort of sad that so many people at the same time work at something that doesn't seem to have any contact with experiment. But that, to some extent, is due to the fact that we don't have any great experimental puzzle to be thinking about. We have to supply the puzzles, and there aren't that many puzzles right now.
