„I do not define time, space, place, and motion, as being well known to all.“

Philosophiae Naturalis Principia Mathematica (1687)
Contexte: I do not define time, space, place, and motion, as being well known to all. Only I must observe, that the common people conceive those quantities under no other notions but from the relation they bear to sensible objects. And thence arise certain prejudices, for the removing of which it will be convenient to distinguish them into absolute and relative, true and apparent, mathematical and common.

„Galileo had raised the concepts of space and time to the status of fundamental categories by directing attention to the mathematical description of motion.“

—  Gerald James Whitrow British mathematician 1912 - 2000

The Structure of the Universe: An Introduction to Cosmology (1949)
Contexte: Galileo had raised the concepts of space and time to the status of fundamental categories by directing attention to the mathematical description of motion. The midiaevel qualitative method had made these concepts relatively unimportant, but in the new mathematical philosophy the external world became a world of bodies moving in space and time. In the Timaeus Plato had expounded a theory that outside the universe, which he regarded as bounded and spherical, there was an infinite empty space. The ideas of Plato were much discussed in the middle of the seventeenth century by the Cambridge Platonists, and Newton's views were greatly influenced thereby. He regarded space as the 'sensorium of God' and hence endowed it with objective existence, although he confessed that it could not be observed. Similarly, he believed that time had an objective existence independent of the particular processes which can be used for measuring it.<!--p.46

„I have tried at times to place humans in perspective against the vastness of universal time and space.“

—  Clifford D. Simak American writer, journalist 1904 - 1988

As quoted in the Associated Press obituary (27 April 1988)
Contexte: I have tried at times to place humans in perspective against the vastness of universal time and space. I have been concerned with where we, as a race, may be going and what may be our purpose in the universal scheme — if we have a purpose. In general, I believe we do, and perhaps an important one.

„Explanations exist; they have existed for all time; there is always a well-known solution to every human problem — neat, plausible, and wrong.“

—  H.L. Mencken American journalist and writer 1880 - 1956

The portion after the second semicolon is widely paraphrased or misquoted. Two examples are "For every complex problem there is an answer that is clear, simple, and wrong" and "There is always an easy solution to every human problem -- neat, plausible, and wrong."

„The equation of motion holds at all times, it is in this sense eternal“

—  Werner Heisenberg German theoretical physicist 1901 - 1976

Physics and Philosophy (1958)
Contexte: The equation of motion holds at all times, it is in this sense eternal, whereas the geometrical forms, like the orbits, are changing. Therefore, the mathematical forms that represent the elementary particles will be solutions of some eternal law of motion for matter. Actually this is a problem which has not yet been solved.<!-- p. 72

Contexte: It is the invariable lesson to humanity that distance in time, and in space as well, lends focus. It is not recorded, incidentally, that the lesson has ever been permanently learned.

„The cutting of films is a parable in the motion of any art that lives in time, as well as a parable in the ethics of communication.“

—  Muriel Rukeyser poet and political activist 1913 - 1980

Source: The Life of Poetry (1949), p. 150
Contexte: The continuity of film, in which the writer deals with a track of images moving at a given rate of speed, and a separate sound-track which is joined arbitrarily to the image-track, is closer to the continuity of poetry than anything else in art. But the heaviness of the collective work on a commercial film, the repressive codes and sanctions, unspoken and spoken, the company-town feeling raised to its highest, richest, most obsessive-compulsive level in Hollywood, puts the process at the end of any creative spectrum farthest from the making of a poem.
At the same time, almost anything that can be said to make the difficulties of poetry dissolve for the reader, or even to make the reader want to deal with those "difficulties," can be said in terms of film. These images are like the action sequences of a well-made movie — a good thriller will use the excitement of timing, of action let in from several approaches, of crisis prepared for emotionally and intellectually, so that you can look back and recognize the way of its arrival; or, better, feel it coming until the moment of proof arrives, meeting your memory and your recognition.
The cutting of films is a parable in the motion of any art that lives in time, as well as a parable in the ethics of communication.
