An engineer uses scientific knowledge to solve practical problems.[1] According to the Merriam Webster's collegiate dictionary, engineering is defined as "the application of science and mathematics by which the properties of matter and the sources of energy in nature are made useful to people." [2]

There are many branches of engineering, including electrical, mechanical, civil, chemical, aerospace, biomedical, agricultural, environmental, industrial, and materials engineering.[3] Many American colleges offer engineering degrees.

Usually a person trained and skilled in the design, construction, and use of engines or machines, or in any of various branches of engineering.

In the U. S. and Canada, the title of "Professional Engineer" and often also titles indicating a specific branch of engineering, such as "Civil engineer" or "Mechanical engineer" are restricted.[4][5][6] In mainland Europe engineering is seen as comparable to other professions such as medicine and architecture.

In U. S. Army, Navy and Air Force, a person that is specially trained in engineering work.

A major difference between an engineer and other types of designers is that an engineer is held responsible for the success of his designs. An engineer who plans a bridge can lose his engineering license if the bridge collapses.

Engineer also refers to someone who operates train locomotives.
