An engineer is someone who practices the profession of engineering. Engineers use creativity, technology, and scientific knowledge to solve practical problems. The title "engineer" is normally used only by individuals who have an academic degree (or equivalent work experience) in one of the engineering disciplines. In some countries of Continental Europe the title is limited by law to people with an engineering degree, and the use of the title by others (even persons with equivalent work experience) is illegal. Similar laws exist in most if not all American states and Canadian provinces; they usually dictate that only those who have passed the Professional Engineer examination may call themselves engineers. However, the reach of such laws is often limited to cover only situations involving intentional deceit or fraud. The word "technologist" is sometimes used synonymously as it derives from the prefix Techno- and the suffix -ologist, hence, someone who studies technology. This applies particularly to those European countries with laws regulating the use of the title engineer, since the term technologist is not regulated. However in some Latin countries, "technologist" is a somewhat lower certification at a level between technician and engineer.
Engineers and scientists are often confused in the minds of the general public. While scientists explore nature in order to discover general principles, engineers apply established principles drawn from mathematics and science in order to develop economical solutions to technical problems. The work of engineers is the link between perceived social needs and commercial applications. Engineers consider many factors when developing a new product. For example, in developing an industrial robot, engineers precisely specify the functional requirements; design and test the robot’s components; integrate the components to produce the final design; and evaluate the design’s overall effectiveness, cost, reliability, and safety. This process applies to the development of many different products, such as chemicals, computers, engines, aircraft, and toys.
