A designed, mechanical system -- like a constantly functioning clock.
Explanation:
Newton explained the universe and its functioning in his landmark work, <em>Mathematical Principles of Natural Philosophy </em>(1687). He pulled together the work of other key figures of the Scientific Revolution. His organized theory of universal gravitation gave the impression of the universe as a mathematical system that functioned like clockwork. Newton and others of the Scientific Revolution saw God behind the design of this system, as the "great watchmaker" who designed the universe as a perpetual watch or clock that could run on perpetually in predictable fashion.
