Since the motion of a pendulum is a constant time interval, a pendulum inside a clock can keep the hands running on time. Often, as in the case of a grandfather clock ...
Penrod and Hupcey developed the Principle-Based Concept Analysis approach based on Morse et al. to define concepts based on principles exclusively within scientific use, disregarding creative interpretations found in art or fiction. The intentional and strategic extraction of data forms the foundation of this method.
