What is an Engineer?

To pin-point exactly what it is that an engineer does is not an easy task.  In essence, an engineer is a problem-solver.  However, the engineer of today applies his or her skills to such a vast array of scientific fields and performs such a wide variety of tasks – today’s engineer does more than solve problems.  To engineer something is to create it, modify it, upgrade it and/or test it.  To be an engineer, one must often do much more than that.
