In the evening I study a fair.. ..if you could see the pomp and luxury — Giacomo Balla

"It will interest artists because, in it, I have made a special study of the way of walking of this girl, and, in fact, I have succeeded in giving the illusion that she is in the process of moving forward."

"Villages and valleys pass by [Balla viewed during his train voyage to Düsseldorf in July 1912] and with my friend the binoculars [field glasses] I stare into the closest windows; semi-undressed people who wash themselves, bedding on balconies, clean almost empty rooms, a stupendous white shoulder of a women who, with a nude arm opens a door and goes inside."

"Use materials with forceful MUSCULAR colours – the reddest of reds, the most purple of purples, the greenest of greens, intense yellows, orange, vermillion – and SKELETON tones of white, grey and black."

"And we must invent dynamic designs to go with them and express them in equally dynamic shapes: triangles, cones, spirals, ellipses, circles, etc."

"As a result we shall have the necessary variety of clothes, even if the people of a given city lack the imagination themselves. The happiness of our Futurist clothes will help to spread the kind of good humour aimed at by my great friend PaIazzeschi in his futurist Manifesto against Sadness."

"They [ Boccioni and Severini ] did not want anything to do with me in Paris and they were right: they have gone much further than I, but I will work and I too will progress."

"The absolute requisites for the study of this work... are a knowledge of algebra to the binomial at least, plane and solid geometry, plane trigonometry, and the most simple part of the usual applications of algebra to geometry. ...A. De Morgan. London July 1, 1836"

"A free people will always refuse to put up with preventable poverty. If freedom is to be saved and enlarged, poverty must be ended. There is no other solution. The problem of how to prevent these three forces from coming into head-on collision is the principal study of the more politically conscious Conservative leaders. How can wealth persuade poverty to use its political freedom to keep wealth in power? Here lies the whole art of Conservative politics in the twentieth century."

"A clear prediction in an area undergoing vigorous study permits doctrines to be subject to disproof. The last posture a bureaucratic religion wishes to find itself in is vulnerability to disproof, where an experiment can be performed on which the religion stands or falls."

"Spencer argued in a very articulate way for the communality of these processes of self-organization, and used his ideas to make a theory of sociology. However, he was not able to put these ideas into mathematical form or argue them from first principles. And no one else has, either — doing so is perhaps the central problem in the study of complex systems."

"The commercial exploitation of the web has become a growing facet of the world economy, particularly in the last several years. In June 1999 NUA Internet Surveys estimated that 179 million people are connected to the Internet worldwide. A recent study by the sponsored by estimated that the "Internet Economy" generated $300 billion in revenue in the United States alone."

"In biology the Cartesian view of living organisms as machines, constructed from separate parts, still provides the dominant conceptual framework. Although Descartes simple mechanistic biology could not be carried very far and had to be modified considerably during the subsequent three hundred years, the belief that all aspects of living organisms can be understood by reducing them to their smallest constituents, and by studying the mechanisms through which these interact, lies at the very basis of most contemporary biological thinking. This passage from a current textbook on modern biology is a clear expression of the reductionist credo: One of the acid tests of understanding an object is the ability to put it together from its component parts. Ultimately, molecular biologists will attempt to subject their understanding of cell structure and function to this sort of test by trying to synthesize a cell."
