Engineering by Faith Pardue DeBolt
What engineers do:
Engineers put math and science into action to develop desirable technologies, advanced structures and innovative solutions to everyday problems, and to make our lives easier. Examples of such solutions include advanced micro-electronics, wind turbines, biomedical nano-robots, fuel efficient cars, bridges and sky scrapers, materials such as high tech fabric and solar panels, and much more.
How you decided on becoming and engineer:
My high school algebra/calculus and physics/pre-calculus teachers strongly encouraged me to become a mechanical engineer. I'm very glad I followed their lead as I enjoy the challenges of creative problem solving, innovative analysis and research continually presented to me.
What degree(s) you would need:
For an entry-level engineering position, typically a four-year engineering degree is required, although some places may accept applicants with four-year math or science degrees. For more advanced positions involving research, at least a master's degree is necessary.
Classes you need to take in high school to prepare:
Undergraduate engineering programs typically require a strong foundation in math (algebra, geometry, trigonometry and calculus) and science (physics, biology, and chemistry) as well as above average performance in language, social sciences and humanities.
Special interests that may make it easier:
One who enjoys math, science, understanding how things work, problem diagnosis and solving, analysis, and/or inventing new things would make an excellent engineer.
Engineers earn some of the highest starting salaries among those holding bachelor's degrees, ranging from $52,000 for civil engineers to $83,000 for petroleum engineers. Among all engineering professions and experience levels, average salaries vary from $43,000 to over $160,000.
With the focus of engineering demand in the 21st century in the U.S. shifting from manufacturing to civil, biomedical and consulting services, job outlook for engineers is remaining strong but in different fields than in the 20th century. Overall, expected growth through 2018 is 11%, with the strongest potential in the biomedical, civil, environmental and petroleum fields.
