The danger of what you don't know you don't know

摘要

Think of an engineering degree as a license to learn rather than an end in itself. Engineering disciplines, like a lot of educational disciplines, have become very narrowly focused. At some level this is a necessary trend, since to be expert in every aspect of a field has become something that is almost impossible to accomplish. An engineering student attempting to delve deeply enough in every aspect of his or her chosen discipline to be an "expert" would never finish college.
