Course Syllabus
Most things covered in class will show up on a test/quiz.
Take notes and study. 5 minutes a night helps a lot more than you’d expect.
Remember – this course is designed to prepare you to do well in college, regardless of your major.
Unless otherwise specified, it’s okay to work with your partner on drills and classwork. Keep talk focused.
You need permission and a hall pass to leave class.
What is Engineering?Application of:
Math -Science -
Technical -Principles
to Create tangible, practical solutions
Problem Solving
Theory in Practice
Knowledge in Action
Manufacturing
Designing Solutions
Manifesting Ideas
Science vs. Engineering
Science:1. Systematically obtaining knowledge by observation and
experience2. Use the Scientific Method3. Empirical / Objective
Engineering:1. Application of math and science by which matter and
energy are made useful to people2. Designing and implementing solutions that fulfill an
objective, need, or desire – based on knowledge3. Subjective solutions based on objective knowledge
“Engineering. . .to define rudely but not inaptly is the art of doing that well with one dollar, which any bungler can do with two
after a fashion.”
– Arthur Mellen Wellington,
The Economic Theory of Railway Location (1911)
Science vs. Engineering
Dr. Oct – scientist or engineer?NASA – scientists or engineers?

12. Process Engineering – focuses on the design, operation and maintenance of chemical and other process manufacturing activities. Process engineering is often a synonym for chemical engineering but process engineers are found in a vast range of industries, such as the petrochemical, mineral processing, material, information technology, food and pharmaceutical and biotechnological industries. Process engineering also involves developing new processes, project engineering and troubleshooting.
