What is Engineering?What is Engineering?
Two Types of Definitions• Career Based• Functional
Career Description• Engineering is a CAREER and a
PROFESSION– Requires Special Education, Training, and
Experience For a Working Lifetime of Practice– Not Quite Analogous to Physicians & Attorneys
License NOT required to Practice in Most Cases

Best “Professional” Analogy → Certified Public Accountant (CPA)
Licenses Granted by States • Must Meet Strict Educational, Practice, and
Testing Criteria to Earn the Professional Engineer (P.E.) Title
Currently 2x106 Engineers in the USA• About 18% Hold Professional Licenses

Some Engineering Functions can NOT be done by UnLicensed Engineers• MOST Civil Engineering Designs MUST be
“Signed Off” or “Stamped” by a Registered, Professional Engineer

Functional Description:• Short Answer = Technical Problem Solving
– The Output of ALL Engineering isThe Solution to a Practical ProblemFulfillment of a Practical Need
• Long Answer = Practical-Problem Solving Through the Application of the Quantitative (Number-Based) Disciplines– Mathematics
– Sciences; e.g., Physics, Chemistry, Biology
– Empiricism (Experiments and Tests)

What do Engineers Do?What do Engineers Do?
Dozens of Branches of Engineering; The Major Disciplines include:
Civil Engineering (CE)• typical Products = Bridges, Buildings,
Roadways, Water Systems
Chemical Engineering (ChemE)• typical Products =
Oil & Gas Refineries
24
Tom Rebold, MSEEIntroduction to Engineering
What Do Engineers Do?What Do Engineers Do?Cont.1 Cont.1
Electrical/Electronic Engineering (EE)• typical Products =
– Integrated Circuits (“computer chips”)
– Electricity Distribution (“PG&E”)
Industrial/Manufact. Engineering (IE)• typical Products = Efficient Factories
Materials Science & Engineering (MSE)• typical Products = High Performance
Metals, Ceramics, Composites (graphite)
25

Computer (Science) Engineering (CS)• typical Products = Software Code
Mechanical Engineering (ME)• typical Products =
– Machinery (automobiles, pumps, mach-tools)
– Heat & Fluid-Flow Distribution (“HVAC”)

Engineering vs. ScienceEngineering 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

What is COOL about Engineering?What is COOL about Engineering?
Solving Challenging Problems Opportunity to DESIGN, BUILD, and
TEST Products that People Really Use• Engineering is a CREATIVE endeavor
– The Root of the Word “Engineer” is Ingenium; Not Engine
Chance to Learn New Things• Engineering is about Progress; an
Engineer’s Knowledge & Skills progress as well
30
Tom Rebold, MSEEIntroduction to Engineering
What is COOL about Engineering?What is COOL about Engineering?Cont.1Cont.1
Working with People• That’s Right; Not all Engineers are “Nerds”
• Complex Technology Must Be Made Useful to the Non-Technical Person
• Engineers, aside from applied Math/Sci, manage Projects and Organizations– Technical Projects can require the Input of Many
People. Project Engineers Manage Activities toEnsure the Project Meets Technical RequirementsStay on the Time-ScheduleStay within the $-Cost-Budget
31
Tom Rebold, MSEEIntroduction to Engineering
What is COOL about Engineering?What is COOL about Engineering? Publishing Technical Papers
• Thousands of Engineering/Technical Journals Publish Results of Engineer’s Analyses, Designs, Experiments

Earning Patents• Earning A Patent Requires the
Advancement of a Practical Art; This is what Engineers do
USA Constitution, Article 1, Section 8 (Powers Granted to Congress):
Clause 8: To promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries

Tom Rebold, MSEEIntroduction to Engineering
What is COOL about Engineering?What is COOL about Engineering?Cont.2Cont.2
Engage in Professional Activities• Attend/Present-At Technical Conferences• Attend Trade-Shows• Society Membership (ASCE, IEEE, ASME)
See the World – Engineers often Travel• Special Knowledge/Skills Can often ONLY
be Transmitted In-Person– Promote/Explain Product to Customers– Install Product, Train Users -Site Product-Testing
34
Tom Rebold, MSEEIntroduction to Engineering
The Bottom LineThe Bottom Line
There are VERY FEW Academic Disciplines Where One Can Move Into PRIVATE INDUSTRY with A Bachelor of Science (4yr) Degree• TWO Primary Categories
– Engineering
– Business
• Difficult for Most Liberal Arts Disciplines
• Somewhat Easier for the Sciences

Tom Rebold, MSEEIntroduction to Engineering
Engineering is Fun (Really...Engineering is Fun (Really...☺)☺) An overwhelming majority of survey takers,
91%, feel that engineering is FUN. Their reasons include the chance to tackle challenging problems and something different every day. • "I like solving problems, being the hero."• "I get paid to break things."• "So many challenges! New stuff to play with
around every corner."• "I love proving others wrong."• "I'm like a kid in a candy shop.“• “Engineering Rocks”
