               6.2      Early Forms of Scientific Methods


                   The scientific method is the backbone of scientific and technological progress. Before

               the emergence of modern scientific methodologies, early civilizations developed system-

               atic ways of observing nature, explaining phenomena, and solving problems. These early
               forms of scientific methods laid the foundation for contemporary science, engineering,

               and computing. For students of computers and information sciences, understanding early

               scientific methods is important because modern computational thinking, algorithm de-
               sign, and experimental evaluation are extensions of these early systematic approaches to

               knowledge and problem solving.
