TEXT C Many objects in daily use
have clearly been influenced by science, but their form and function, their
dimensions and appearance, were determined by technologists, artisans,
designers, inventors, and engineers using non-scientific modes of thought. Many
features and qualities of the objects that a technologist thinks about cannot be
reduced to unambiguous verbal descriptions; they are dealt with in the mind by a
visual, nonverbal process. In the development of Western technology, it has been
non-verbal thinking, by and large, that has fixed the outlines and filled in the
details of our material surroundings. Pyramids, cathedrals, and
rockets exist not because of geometry or thermodynamics, but because they were
first a picture in the minds of those who built them. The creative shaping
process of a technologist’s mind can be seen in nearly every artifact that
exists. For example, in designing a diesel engine, a technologist might impress
individual ways of nonverbal thinking on the machine by continually using an
intuitive sense of rightness and fitness. What would be the shape of the
combustion chamber Where should the valves be placed Should it have a long or
short piston Such questions have a range of answers that are supplied by
experience, by physical requirements, by limitations of available space, and not
least by a sense of form. Some decisions, such as wall thickness and pin
diameter, may depend on scientific calculations, bat the nonscientific component
of design remains primary. Design courses, then, should be an
essential element in engineering curricula. Nonverbal thinking, a central
mechanism in engineering design, involves perceptions, the stock-in-trade of the
artist, not the scientist. Because perceptive processes are not assumed to
entail "hard thinking," nonverbal thought is sometimes seen as a primitive stage
in the development of cognitive processes and inferior to verbal or mathematical
thought. But it is paradoxical that when the staff of the Historic American
Engineering Record wished to have drawings made of machines and isometric views
of industrial processes for its historical record of American engineering, the
only college students with the requisite abilities were not engineering
students, but rather students attending architectural schools.
Its courses in design, which in a strongly analytical engineering
curriculum provide the background required for practical problem-solving, are
not provided, we can expect to encounter silly but costly errors occurring in
advanced engineering systems. For example, early models of high-speed railroad
cars loaded with sophisticated controls were unable to operate in a snowstorm
because a fan sucked snow into the electrical system. Absurd random failures
that plague automatic control systems are not merely trivial aberrations; they
are a reflection of the chaos that results when design is assumed to be
primarily a problem in mathematics. (447) Which of the following statements would best serve as an introduction to the passage
A.The assumption that the knowledge incorporated in technological developments must be derived from science ignores the many non-scientific decisions made by technologists. B.Analytical thought is no longer a vital component, in the success of technological development. C.As knowledge of technology has increased, the tendency has been to lose sight of the important role played by scientific thought in making decisions about form, arrangement, and texture. D.A technologist thinking about a machine, reasoning through the successive steps in a dynamic process, can actually turn the machine over mentally.
