« All quotes from this author
 

There does not exist a category of science to which one can give the name applied science. There are sciences and the applications of science, bound together as the fruit of the tree which bears it.
--
Revue Scientifique (1871)
--
Variant translation: There are no such things as applied sciences, only applications of science.

If you sense a deep human need, then you go back to all the basic science. If there is some missing, then you try to do more basic science and applied science until you get it. So you make the system to fulfill that need, rather than starting the other way around, where you have something and wonder what to do with it.

 
Edwin H. Land
 

Both pure and applied science have gradually pushed further and further the requirements for accuracy and precision. However, applied science, particularly in the mass production of interchangeable parts, is even more exacting than pure science in certain matters of accuracy and precision.

 
Walter A. Shewhart
 

The true line is not between “hard” natural science and “soft” social sciences, but between precise science limited to highly abstract and simple phenomena in the laboratory and inexact science and technology dealing with complex problems in the real world.

 
Herbert Simon
 

I think the new science fiction, which other people apart from myself are now beginning to write, is introverted, possibly pessimistic rather than optimistic, much less certain of its own territory. There's a tremendous confidence that radiates through all modern American science fiction of the period 1930 to 1960; the certainty that science and technology can solve all problems. This is not the dominant form of science fiction now. I think science fiction is becoming something much more speculative, much less convinced about the magic of science and the moral authority of science. There's far more caution on the part of the new writers than there was.

 
J. G. Ballard
 

When a man sets out upon any course of inquiry, the object of his search may be either light or fruit — either knowledge for its own sake or knowledge for the sake of good things to which it leads. In various fields of study these two ideals play parts of varying importance. In the appeal made to our interest by nearly all the great modern sciences some stress is laid both upon the light-bearing and upon the fruit-bearing quality, but the proportions of the blend are different in different sciences. At one end of the scale stands the most general science of all, metaphysics, the science of reality. Of the student of that science it is, indeed, true that "he yet may bring some worthy thing for waiting souls to see"; but it must be light alone, it can hardly be fruit that he brings. Most nearly akin to the metaphysician is the student of the ultimate problems of physics. The corpuscular theory of matter is, hitherto, a bearer of light alone. Here, however, the other aspect is present in promise; for speculations about the structure of the atom may lead one day to the discovery of practical means for dissociating matter and for rendering available to human use the overwhelming resources of intra-atomic energy.
