A stage design program can teach students how to create scenery, backgrounds, and sets for a variety of different performances and presentations. Courses might cover everything from construction to color theory, as well as lighting and backdrops.

The PhD is a doctoral degree, specifically called a "doctor of philosophy" degree.

That said, PhD recipients are able to engage in thought experiments, reason about problems, and solve problems in sophisticated ways.
