What is technological science?

The technological sciences have at least six defining characteristics that distinguish them from the other sciences. They (1) have human-made rather than natural objects as their (ultimate) study objects, (2) include the practice of engineering design, (3) define their study objects in functional terms, (4) evaluate these study objects with category-specified value statements, (5) employ less far-reaching idealizations than the natural sciences, and (6) do not need an exact mathematical solution when a sufficiently close approximation is available. In combination, the six characteristics are sufficient to show that the technological sciences are neither branches nor applications of the natural sciences, but form a different group of sciences with specific characteristics of their own.
