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

19


What is Engineering?What is Engineering?Cont.1Cont.1

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

P.E. ExclusivesP.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

21


What is Engineering?What is Engineering?Cont.2Cont.2

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


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


What Do Engineers Do?What Do Engineers Do?Cont.2Cont.2

Computer (Science) Engineering (CS)• typical Products = Software Code

Mechanical Engineering (ME)• typical Products =

– Machinery (automobiles, pumps, mach-tools)

– Heat & Fluid-Flow Distribution (“HVAC”)

26


What Do Engineers Do?What Do Engineers Do?Cont.3Cont.3

BioEngineering – a NEW Discipline“…. a discipline that advances knowledge in engineering, biology and medicine, and improves human health through cross-disciplinary activities that integrate the engineering sciences with the biomedical sciences and clinical (medical) practice”

- Whitaker Foundation

• Some Typical Products– Biomaterials/Tissue Engineering

– Biomedical Electronics & Imaging

– Biomechanics

28


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

29


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


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


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

32



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

33



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


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

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”
