Yes! As my math/physics teacher always told me in school, "If you can draw the picture, then you can do the problem." Granted, many advanced concepts are harder to draw a picture of than a ladder leaning against a wall to determine the free body diagram, but just look at some of the great work being done at phdcomics to express scientific concepts graphically. A picture is worth a thousand words and maybe at least a dozen equations.

I work for a small DoD contractor, and yours is a skill set that we have hired several times before. I would definitely be interested in seeing a resume.
