“I have also cleared the electromagnetic theory of light from all unwarrantable assumption, so that we may safely determine the velocity of light by measuring the attraction between bodies kept at a given difference of potential, the value of which is known in electromagnetic measure.”

James Clerk Maxwell (1831–1879) Scottish physicist

“We must speak the truth about terror. Let us never tolerate outrageous conspiracy theories concerning the attacks of September the 11th; malicious lies that attempt to shift the blame away from the terrorists, themselves, away from the guilty. To inflame ethnic hatred is to advance the cause of terror.”

George W. Bush (1946) 43rd President of the United States

“He was more than willing to instruct me, and in my notebook he actually wrote in his own hand the three commandments he considered sufficient to make any firm prosper: 1. There’s no need for a man to know how to work, but if he doesn't know how to make others work, he is doomed. (2) There is only one great regret: not having acted in one's own best interest. (3) In business, theory is useful, but it can be utilized only after the deal has been made.”

Era dispostissimo ad istruirmi, ed anzi annotò di propria mano nel mio libretto tre comandamenti ch'egli riteneva bastassero per far prosperare qualunque ditta: 1. Non occorre saper lavorare, ma chi non sa far lavorare gli altri perisce. 2. Non c'è che un solo grande rimorso, quello di non aver saputo fare il proprio interesse. 3. In affari la teoria è utilissima, ma è adoperabile solo quando l'affare è stato liquidato.

“The development during the present century is characterized by two theoretical systems essentially independent of each other: the theory of relativity and the quantum theory. The two systems do not directly contradict each other; but they seem little adapted to fusion into one unified theory.”

Hermann Weyl photo

“It seems clear that [set theory] violates against the essence of the continuum, which, by its very nature, cannot at all be battered into a single set of elements. Not the relationship of an element to a set, but of a part to a whole ought to be taken as a basis for the analysis of a continuum.”

Hermann Weyl (1885–1955) German mathematician

“An enduring embarrassment of democratic theory is that it seems impotent when faced with questions about its own scope.”

“I quote somewhere a correspondence with Ken Arrow, after he wrote Arrow and Hahn. I wrote to him and I said that the trouble is that neoclassical economists confuse risk with uncertainty. Uncertainty means non-probabilistic. And he said, 'Quite true, you're quite correct that Keynes is much more fruitful, but the trouble with the General Theory is, those things that were fruitful couldn't be developed into a nice precise analytical statement, and those things that could were retrogressions from Keynes but could be developed into a nice precise analytical statement.' That's why mainstream economics went that route. And my answer is, I would hope that even Nobel Prize winners didn't believe that regression is growth, which it clearly isn't. But that's right. The fear that everybody has, you see, is nihilism: you won't be able to say what's going to happen. Well, evolutionists don't worry about being unable to predict. You ask the evolutionists, who tell you what happened in the past, just what next species is going to appear, and the answer is, anything could. Right? Does that bother people? Explanation is the first thing in science. If you can't explain, you don't have anything. But you needn't necessarily predict. Now, if you know the future's uncertain, what does that mean? It means basically, the way Hicks put it in his later years, that humans have free will. The human system isn't deterministic or stochastic, which is deterministic with a random error. Humans can do thins to change the world.”

“At different stages in the educational process different changes are required. In schools the chief need is for a general change in the attitude towards science, which should be from the beginning an integral part and not a mere addition, often an optional addition, to the curriculum. Science should be taught not merely as a subject but should come into all subjects. Its importance in history and in modern life should be pointed out and illustrated. The old contrast, often amounting to hostility, between scientific and humane subjects need to be broken down and replaced by a scientific humanism. At the same time, the teaching of science proper requires to be humanized. The dry and factual presentation requires to be transformed, not by any appeal to mystical theory, but by emphasizing the living and dramatic character of scientific advance itself. Here the teaching of the history of science, not isolated as at present, but in close relation to general history teaching, would serve to correct the existing atmosphere of scientific dogmatism. It would show at the same time how secure are the conquests of science in the control they give over natural processes and how insecure and provisional, however necessary, are the rational interpretations, the theories and hypotheses put forward at each stage. Past history by itself is not enough, the latest developments of science should not be excluded because they have not yet passed the test of time. It is absolutely necessary to emphasize the fact that science not only has changed but is continually changing, that it is an activity and not merely a body of facts. Throughout, the social implications of science, the powers that it puts into men's hands, the uses they could make of them and those which they in fact do, should be brought out and made real by a reference to immediate experience of ordinary life.”

John Desmond Bernal (1901–1971) British scientist

“This faulty intuition as well as many modern applications of probability theory are under the strong influence of traditional misconceptions concerning the meaning of the law of large numbers and of a popular mystique concerning a so-called law of averages.”

“We have been attempting to relieve ourselves and the other nations from the old theory of competitive armaments. In spite of all the arguments in favor of great military forces, no nation ever had an army large enough to guarantee it against attack in time of peace or to insure its victory in time of war. No nation ever will. Peace and security are more likely to result from fair and honorable dealings, and mutual agreements for a limitation of armaments among nations, than by any attempt at competition in squadrons and battalions. No doubt this country could, if it wished to spend more money, make a better military force, but that is only part of the problem which confronts our Government. The real question is whether spending more money to make a better military force would really make a better country. I would be the last to disparage the military art. It is an honorable and patriotic calling of the highest rank. But I can see no merit in any unnecessary expenditure of money to hire men to build fleets and carry muskets when international relations and agreements permit the turning of such resources into the making of good roads, the building of better homes, the promotion of education, and all the other arts of peace which minister to the advancement of human welfare. Happily, the position of our country is such among the other nations of the world that we have been and shall be warranted in proceeding in this direction.”

“Based on the metaphysical implications of the Dadaist dogma.... Arp's Reliefs [carvings] between 1916 and 1922 are among the most convincing illustrations of that anti- rationalistic era... Arp showed the importance of a smile to combat the sophistic theories of the moment. His poems of the same period stripped the word of its rational connotation to attain the most unexpected meaning through alliteration or plain nonsense.”
