Seriously, I'm a geophysicist. Most people don't know what that is, so I usually just say \\\\\\\"geologist\\\\\\\". We're the quantitative geologists--we apply physics to see underground, using things like seismic and EM and radar. I deal usually with EM, and specifically with computer modeling of the governing physics. Why model a fake earth? You have to in order to understand the signals you measure from the real one. I program a lot, and I also get to go out and get dirty in the field collecting data. I teach all of this, too, to ungrateful students
who mostly go \\\\\\\"Oh noes!1! U got math in mah geology!!1!\\\\\\\"

Here's the first paper I ever wrote if you're curious)
