The art or science of using imagination to intuitively make practical applications from knowledge. Imagination and intuition are the foundations of all improvements and advancements that humankind has made. If someone had not imagined that it was possible for man to fly, no one would have attempted to fly. If no one had intuitively reasoned that a propeller shaped like an airfoil could be used to power aircraft, no one would have tried it.
Intuition is the basis for all advancements and new designs.
The design of all prototypes is based solely on intuition. The designer intuitively reasons or imagines the design and designs changes that result in the working prototype. Only after testing does the design cease to be intuitive or imaginative, instead becoming scientific fact. Until then it only existed in the designer's mind or imagination. Intuition is based on applying the physical laws of the physical world to this abstract world in an orderly and consistent manner to make predictions.
