R

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, and Modeling Process. Demonstrate how it's natural to construct a model: select a system, count something (accounting principle), and make modeling assumptions. Illustrate usefulness of symbolic solution.
