Students with a propensity for math and physics may enjoy pursuing training in avionics engineering. Programs in this field can offer courses on CAD and manufacture of parts, troubleshooting mechanical or electronic problems, and aircraft maintenance.

The PhD is a doctoral degree, specifically called a "doctor of philosophy" degree. This is misleading because PhD holders are not necessarily philosophers (unless they earned their degree in philosophy!). That said, PhD recipients are able to engage in thought experiments, reason about problems, and solve problems in sophisticated ways.
