A new development began for relativity theory after 1925 with its absorption into quantum physics. The first great success was scored by Dirac's quantum mechanical equations of the electron, which introduced a new sort of quantities, the spinors, besides the vectors and tensors into our physical theories. ...But difficulties of the gravest kind turned up when one passed from one electron or photon to the interaction among an indeterminate number of such particles. In spite of several advances a final solution of this problem is not yet in sight and may well require a deep modification of the foundation of quantum mechanics, such as would account in the same basic manner for the elementary electric charge e as relativity theory and our present quantum mechanics account for c and h.

That classical theory had catastrophic implications for the constitution of matter was barely appreciated by Planck and others at the turn of the century, and played no substantial role in the development of quantum theory until Bohr's work 13 years later.
The lesson that could be drawn from this, and also from the development of general relativity, is that a crisis will only become creative if it is formulated in a mathematically precise manner. This conclusion has an echo in Bell's insistence on having quantum mechanics "fully formulated in mathematical terms, with nothing left to the discretion of the theoretical physicist", but what it really calls for is a critique of the "orthodox" theory fully formulated in mathematical terms with nothing left to the discretion of the critic.

First, most producers are employees of firms, not owners. Viewed from the vantage point of classical [economic] theory, they have no reason to maximize the profits of firms, except to the extent that they can be controlled by owners. Moreover, profit-making firms, nonprofit organizations, and bureaucratic organizations all have exactly the same problem of inducing their employees to work toward organizational goals. There is no reason, a priori, why it should be easier (or harder) to produce this motivation in organizations aimed at maximizing profits than in organizations with different goals. If it is true in an organizational economy that organizations motivated by profits will be more efficient than other organizations, additional postulates will have to be introduced to account for it.

Quite all right, sir. Plenty of time. You have a sleep, sir.'
Hood turned over with his fat bottom towards Nabby Adams. Thank God. Nabby Adams tiptoed over again to the serving-hatch, ordered another, downed it. He began to feel a great deal better. After yet another he felt better still. Poor old Robin Hood wasn't such a bad type. Stupid, didn't know a gear-box from a spare tyre, but he meant well. The world generally looked better. The sun shone, the palms shook in the faint breeze, a really lovely Malay girl passed by the window. Proud of carriage, in tight baju and rich sarong, she balanced voluptuous haunches. Her blue-black hair had some sort of a flower in it; how delicate the warm brown of her flat flower-like face.
‘What time is it, Nabby?'....

At present, I am particularly excited by 'bad taste'. I have the deep feeling that there exists in the very essence of bad taste a power capable of creating those things situated far beyond what is traditionally termed 'The Work of Art'. I wish to play with human feeling, with its 'morbidity' in a cold and ferocious manner. Only very recently I have become a sort of gravedigger of art (oddly enough, I am using the very terms of my enemies). Some of my latest works have been coffins and tombs. During the same time I succeeded in painting with fire, using particularly powerful and searing gas flames, some of them measuring three to four meters high. I use these to bathe the surface of the painting in such a way that it registered the spontaneous trace of fire.

... an undercurrent of thought was going on in my mind which gave at last a result, whereof it is not too much to say that I felt at once the importance. An electric circuit seemed to close; and a spark flashed forth the herald (as I foresaw immediately) of many long years to come of definitely directed thought and work by myself, if spared, and, at all events, on the part of others if I should even be allowed to live long enough distinctly to communicate the discovery. Nor could I resist the impulse - unphilosophical as it may have been - to cut with a knife on a stone of Brougham Bridge, as we passed it, the fundamental formula which contains the Solution of the Problem, but of course, as an inscription, has long since mouldered away.
