Engineering

Engineering is one of the oldest occupations in history. Without the skills included in the broad field of engineering, up-to-day civilization never could have evolved. The first toolmakers who chipped arrows and spears from rock were the forerunners of modern mechanical engineers. The craftsmen who discovered metals in the earth and found ways to refine and use them were the ancestors of mining and metallurgical engineers. And the skilled technicians who devised irrigation systems and erected the marvelous buildings of the ancient world were the civil engineers of the prestine time. Many of the early branches of engineering were based not on science but empirical information that depended on observation and experience rather than on theoretical knowledge.
