All engineers calculate. Good engineers communicate.
The scientific concepts, analytical processes, and mathematical calculations used to solve engineering problems have been developed over hundreds of years. Early in this period, engineers came to speak a common language, based in mathematics, chemistry, and physics, such that any engineering solution developed anywhere in the world could be read and understood by effectively every engineer.
As more engineering specialties have emerged, engineering “dialects” have arisen. Engineers now must be aware of highly specialized terminology and concepts within their discipline, and as well, must be ever more able to translate them into everyday language that can be understood by clients, end users, and other engineers.
