Engineering is an incredibly broad field which involves the harnessing of mathematical and scientific concepts to create practical and useful things, ranging from automobiles to wind turbines. This field is huge, encompassing people in a wide range of industries, and some people call it “the invisible science,” because engineers are often unsung and unheralded, despite the fact that the work they do is very important. Many colleges and universities offer courses in engineering, for people who are interested in pursuing this field as a career.

Engineering is a very ancient field of human endeavor. Early humans utilized their knowledge of the natural world to figure out things like irrigation schemes and how to build boats which didn't sink. Over time, as humans learned more about science and mathematics, engineering got more complex, and this field paved the way for the modern society we live in today. Chances are that you are benefiting from a product of engineering right now, as you are probably using a computer to read this article.

There are a number of subfields encompassed by engineering. Among these are mechanical, computer, electrical, military, civil, environmental, aerospace, and chemical engineering. All of these fields require different types of training; aerospace engineers, for example, learn a great deal about physics and space in the course of their work, while environmental engineers consider issues like pollution control and the impact of humans on their environment.

Most engineers pride themselves on being problem solvers. Their field of work involves the analysis of a problem, such as the need for a safe and stable water supply for a city, and the creation of a solution, such as an aqueduct. In the course of their work, engineers often interact with people in a number of other fields, and this field of work places a high value on collaboration, fact checking, and quick thinking.

Most countries regulate the practice of engineering, because engineers participate in projects which could be very dangerous if conducted without proper training. Engineers, for example, analyze the plans for structures to ensure that they are sound and stable; an unqualified civil engineer might sign off on plans for a bridge or building which could fail with catastrophic results. Most people who pursue careers in this field go through both graduate and undergraduate training, and they may be required to complete examinations as well.
