Introduction (1)

·   Explain course administrative policies, e.g. development and evaluation activities, homework guidelines, etc.

·   Discuss place of ES201 in SEC.

·   Discuss engineering vs. science, engineering science vs. science; engineering analysis vs. engineering design.

·   Discuss Systems, Accounting, Modeling Process. Demonstrate how its “natural” to construct a model: select a system, count something (accounting principle), and make modeling assumptions. Illustrate usefulness of symbolic solution.
