Science: In its original signification as the Latin translation of the Greek term theoria, science referred to the contemplation of the universal principles of order assumed to rule the universe, principles which were treated as superior to and unchangeable by human beings. In its modern signification science refers to the systematic mathematical modeling, for the sake of prediction and control, of both natural and social systems.
