Simulation is the use of models and/or the actual conditions of either the thing being modeled or the environment in which it operates, with the models or conditions in physical, mathematical, or some other form. The purpose of simulation is to explore the various results which might be obtained from the real system by subjecting the model to representative environments which are equivalent to, or in some way representative of, the situations it is desired to understand or investigate. Simulation may involve system hardware and the actual physical environment, or it may involve mathematical models subjected to mathematical forcing or disturbance functions representative of the systems conditions to be studied.

I have presented the periodic table as a kind of travel guide to an imaginary country, of which the elements are the various regions. This kingdom has a geography: the elements lie in particular juxtaposition to one another, and they are used to produce goods, much as a prairie produces wheat and a lake produces fish. It also has a history. Indeed, it has three kinds of history: the elements were discovered much as the lands of the world were discovered; the kingdom was mapped, just as the world was mapped, and the relative positions of the elements came to take on a great significance; and the elements have their own cosmic history, which can be traced back to the stars.

Our world model was built specifically to investigate five major trends of global concern – accelerating industrialization, rapid population growth, widespread malnutrition, depletion of nonrenewable resources, and a deteriorating environment. The model we have constructed is, like every model, imperfect, oversimplified, and unfinished... Our conclusions are : (1.) If the present growth trends in world population, industrialization, pollution, food production, and resource depletion continue unchanged, the limits to growth on this planet will be reached sometime within the next one hundred years. The most probable result will be a rather sudden and uncontrollable decline in both population and industrial capacity...

Artists have never worked with the model – just with the painting. What you [G. R. Swenson, the interviewer] are really saying is that an artist like Cézanne transforms what we think the painting ought to look like into something he thinks it ought to look like. He's working with paint, not nature; he's making a painting, he's forming. I think my work is different from comic strips – but I wouldn't call it transformation; I don't think that whatever is meant by it is important to art. What I do is form, whereas the comic strip is not formed in the sense I'm using the word; the comics have shapes but there has been no effort to make them intensely unified. The purpose is different, one intends to depict and I intend to unify.

A common monetary standard will be established, with the consent of the various governments, by which industrial transactions will be greatly facilitated. Three spheres made respectively of gold, silver, and platinum, and each weighing fifty grammes, would differ sufficiently in value for the purpose. The sphere should have a small flattened base, and on the great circle parallel to it the Positivist motto would be inscribed. At the pole would be the image of the immortal Charlemagne, the founder of the Western Republic, and round the image his name would be engraved, in its Latin form, Carolus; that name, respected as it is by all nations of Europe alike, would be the common appellation of the universal monetary standard.
Auguste Comte
Men without their choice derive benefits from that association; without their choice they are subjected to duties in consequence of these benefits; and without their choice they enter into a virtual obligation as binding as any that is actual. Look through the whole of life and the whole system of duties. Much the strongest moral obligations are such as were never the results of our option. I allow, that if no supreme ruler exists, wise to form, and potent to enforce, the moral law, there is no sanction to any contract, virtual or even actual, against the will of prevalent power. On that hypothesis, let any set of men be strong enough to set their duties at defiance, and they cease to be duties any longer.
