WHAT IS AN ENGINEER?

• Scientists discover the world that exists
  engineers create the world that never was." -
  Theodore Von Karman aerospace engineering

SCIENCE vs. ENGINEERING

• SCIENCE
• Analysis ask questions, look for patterns,
  develop knowledge
• Produce knowledge
• Characteristic activity research ( learn about
  nature)
• Study of what is

• ENGINEERING
• Synthesis integrate bits of knowledge to create
  something new
• Produce processes and things (part of technology)
• Characteristic activity creative design

What are Some Types of Engineering?

• Just as science is divided into separate fields
  such as biology, chemistry and physics,
  engineering is divided into a variety of
  disciplines. The five largest engineering
  disciplines are chemical, civil, electrical,
  industrial and mechanical. Engineers within all
  of these disciplines can work in product-oriented
  companies, government, or academia.

5
Aerospace Engineering Aerospace engineers design,
analyze, model, simulate, and test aircraft,
spacecraft, satellites, missiles, and rockets.
Aerospace technology also extends to many other
applications of objects moving within gases or
liquids. Examples are golf balls, high-speed
trains, hydrofoil ships, or tall buildings in the
wind. Aerospace engineers are typically
specialists in fields with fancy names such as
aerodynamics, propulsion, navigation, flight
testing, and more.
Biomedical Engineering This is an
interdisciplinary field combining mechanical,
electrical, and chemical engineering to study the
human body. Biomedical Engineers study biology
and medicine to develop technologies related to
health care. They develop medical diagnostic
machines, medical instruments, artificial organs,
joint replacement parts, and prosthetic devices.

Chemical Engineering Chemical Engineers use their knowledge of physics, chemistry, and biology to discover and manufacture better plastics, paints, fuels, fibers, medicines, fertilizers, semiconductors, paper, and all other kinds of chemicals, by carrying out chemical reactions and purifications.
Civil Engineering The design and construction of
buildings, dams, water treatment and carrying
systems, air pollution controls, and
transportation systems are the responsibilities
of civil engineers.  Subheadings of civil
engineering include  geotechnical,
environmental, structural, transportation,
materials, and project management.

Computer Science and Engineering Computer
scientists and engineers are involved in the
development of both hardware and software for
computers. They work on computer-related systems
like CD-ROMs, modems and monitors, as well as
cutting-edge projects including robotics and
virtual reality systems.
Environmental Engineering Keeping the water, air
and soil healthy are the responsibilities of
environmental engineers. To accomplish this goal
they deal with issues including waste management,
pollution control and irrigation.
Electrical Engineering Electrical engineering
deals with electricity, magnetism, and light and
how it is used. Electrical engineers are found in
a variety of companies including the computer,
communications, and automotive industries.

Mechanical Engineering Engineers within this
discipline tend to focus on one of three aspects
of mechanical engineering design, manufacturing,
or energy/power. Cars, airplanes and toys are
just a few of the areas in which mechanical
engineers work. 
Petroleum Engineering Petroleum engineers study
the earth to find oil and gas reservoirs. They
design oil wells, storage tanks, and
transportation systems. They supervise the
construction and operation of oil and gas fields.
Petroleum engineers are researching new
technologies to allow more oil and gas to be
extracted from each well. They help supply the
world's need for energy and chemical raw
materials.

FAQS

• How much do Engineers make???
• Well, let's start out by stating that money
  should never be the only factor for choosing a
  career. What if you end up hating your job?!?!
  Even if you're well paid, remember that money
  can't buy happiness!

FAQS

• What hours do engineers work?  
• Most engineers work weekdays, Monday through
  Friday. That's what some people would call a 'day
  job'. Typically they work from 8 to 10 hours per
  day. There are some companies that have very
  flexible work schedules such that their engineers
  come in for some 8-hour period during the day
  (say from 6 p.m. to 2 a.m.)! Sometimes engineers
  work at a job site where something is happening
  24 hours a day and they work a 'shift' schedule.
  Usually these assignments are temporary, such as
  for a new plant startup.

FAQS

• How long do engineers have to go to school?  
• Engineers need a minimum of a college Bachelor's
  degree. That means they must finish high school
  and typically four years of college. A few
  engineering programs take five years. A college
  degree could take longer if you only attend
  college part time or perhaps attend during
  evenings.

13
FAQS

• How can I become an engineer?
• First you will need a college degree. After that,
  many engineers seek a Professional Engineer
  (P.E.) license. It helps to begin preparations
  for all this at the middle school levels. Where
  possible, choose a well-rounded mix of classes
  with emphasis on math and science. Taken from

IF YOU GUESSED 9/11 YOURE WRONG

• These are images from the 2003 NorthAmerican
  Blackout
• a massive power outage occurred throughout parts
  of the northeastern United States and eastern
  Canada on Thursday, August 14, 2003. It was the
  largest blackout in North American history. It
  affected an estimated 10 million people in the
  Canadian province of Ontario (about one-third of
  the population of Canada), and 40 million people
  in eight U.S. states (about one-seventh of the
  population of the U.S.). Outage-related financial
  losses were estimated at 6 billion USD.

• So HOW did this happen and more importantly how
  can we keep this from happening again?
• These are exactly the type of problems engineers
  work to solve.
• HOMEWORK Answer the following
• What is the power grid? How is it organized?
  What causes the power grid to fail during a
  blackout?
