| Many objects in daily use have clearly
been influenced by science. However, their form and function, their dimensions
and appearance, were determined by technologists, designers, inventors, and
engineers using nonscientific 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, pyramids, cathedrals, and rockets exist not because of geometry or
thermos-dynamics (热动力学), because they were first the picture in the minds of
those. 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 express individual ways of nonverbal thinking on the machine by continually u A.
