2. LiberalsArts Working With STEM • An Effective & Appropriate Working Relationship • My Son Earned a BA in HISTORY from UC Santa Cruz…then No Job

3. What is Engineering? • Short Answer → Audience Suggestions first •  Technical Product Creation  • The Output of ALL Engineering is • The Solution to a Practical Problem • Fulfillment of a Practical Need • Long Answer → Technology Creation Through the Application of the Quantitative (Number-Based) Academic Disciplines • Mathematics • Sciences; e.g., Physics, Chemistry, Biology • Empiricism (Experiments and Tests)

4. Engineering vs. Science • Engineering is Closely Related to Science & Math, but it is NOT the SAME Scientists seek to UNDERSTAND WHAT IS, while Engineers seek to CREATE THAT WHICH NEVER WAS- Theodore von Kármán, CalTech Professor, and the Father of Modern AeroSpace Engineering

5. The First Laser Engineer  Applied Scientist • Laser Sheet-Metal Cutting Machine Engineering Theodore Harold Maiman was born in 1927 in Los Angeles, son of an electrical engineer. He studied engineering physics at Colorado University, while repairing electrical appliances to pay for college, and then obtained a Ph.D. in Physics from Stanford in 1955. Theodore Maiman constructed this first laser in 1960 while working at Hughes Research Laboratories (T.H. Maiman, "Stimulated optical radiation in ruby lasers", Nature, 187, 493, 1960). There is a vertical chromium ion doped ruby rod in the center of a helical xenon flash tube. The ruby rod has mirrored ends. The xenon flash provides optical pumping of the chromium ions in the ruby rod. The output is a pulse of red laser light.

6. Engineer  Applied Scientist Engineers take BASIC Scientific Discoveries and turn them into things that are USEFUL to people. In that role, Engineers are the agents of PROGRESS for Human Society Prof. Jim Plummer, Dean of the Stanford School of Engineering

8. Design is the Pinnacle • The GREATEST Accomplishment in the Engineering Profession → Design of a SUCCESSFUL Product • There are NO Right or Wrong Solutions to a Design Problem • There are only Successful & UNsuccessful Solutions → Largely the result of Creativity • In my ENGR11 Design Class: I can’t define a Successful Design, but I know one when I see one…

9. Example → Design Creativity • Design a Beam-Test Fixture for use in Chabot Engineering Materials Class • BMayer Design • Student Designs

10. WHAT do I DO in the Classroom? • This, ITSELF, is a DESIGN PROBLEM • Develop DESIGN PROJECTS that Must • Involve Applied Science • Be Age Appropriate (Very Difficult Constraint) • Be Inexpensive; $0 to Design, 20$ to Build • Be of 4-16 weeks duration • Be Carefully DOCUMENTED SomeHow • A Documentation-Set is the Ultimate OUTPUT of Design Engineering as required by Practicality • The Design Project may be individual orteam Based (too much emphasis on teams) More in appendix

18. Design → OPEN Ended Problem • In my ENGR11 Design Class: I can’t define a Successful Design, but I know one when I see one… • Two Major Types of Engineering Design • Clean Sheet - No Constraints other than $’s & time • Example (Circa 1950): Design a Random Access Computer Memory → Result ≡ HDD’s • Technology (Code) Constrained • Example: Design the Electrical Power WiringSystem for a Buidling

19. Design: Engineering vs Industrial • Engineering Design MUST Include an applied-SCIENCE Component • Design Engineering is NOT • “Tinkering” → Intuitive “Cut & Try” • “Intuition is often WRONG • INDUSTRIAL Design → Focus is on “Form”, or “Curb Appeal” • Industrial Design Goal → Make it LOOK Cool • Engineering Design Goal → Make it WORK Cool

20. WHAT do I DO in the Classroom? • Copy SomeOne Else’s Design • Learn from the Past → “Don’t Reinvent the Wheel” • Google-City for Designs you can use and IMPROVE • Resources if $-Budget Exists • Lawrence Hall of Science, Exploratorium • Project Lead The Way • Educational Systems Companies: PASCO, Vernier, Etc.

21. WHAT do I DO in the Classroom? • An Easy One to Start: Dissection & Documentation • a.k.a., “Reverse Engineering (Design)” • Students Disassemble a common object (e.g. a power screw driver) to • Understand how the major components interact • Document the parts • Locate Part numbers • Count Quantities • Use Tools • Loose Fear of the Physical
