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

P.E. Exclusives
 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

(STEPS)
ELEMENTS
(ABILITY TO)
• Short Answer = Technical Problem Solving
– The Output of ALL Engineering is
 The Solution to a Practical Problem
 Fulfillment 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)

A personal view:
 The inner world is where your
talents are buried
 The outer world has a claim on your
time, distracts you from them
 Your mission: satisfy the outer while
developing the inner
 Engineering is a great field for these
forces to play out

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

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

Tom Rebold, MSEE
What is COOL about Engineering?
Cont.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 to
 Ensure the Project Meets Technical Requirements
 Stay on the Time-Schedule
 Stay within the $-Cost-Budget

What is COOL about Engineering?
 Publishing Technical Papers
• Thousands of Engineering/Technical Journals Publish
Results of Engineer’s Analyses, Designs, Experiments

What is COOL about Engineering?
Cont.2
 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

What is COOL about Engineering?
Cont.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

The 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

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”
