engineer

A person capable of making things work in unfathomable and near-magical ways. Generally possesses extreme levels of mechanical aptitude plus a formal education including large doses of applied math, physics and chemistry which he actually understands. Can perform calculations without using a calculator. Often builds his own mechanical devices from loose parts for self-amusement. A modern day witch. Often has difficulty relating to people because ideas on new and better ways of doing things are constantly flooding into his/her mind. In many cases just bringing an engineer into a room containing broken equipment causes the equipment to start working again.
