The LPI scientist at our workshop is Dr. Tomasz Stepinski, who works on computer modeling. Currently he's working on an A.I. that will catalog all of the large and small impact craters on the Martian surface. Listening to him speak brings me back to high school chemistry. Tom is originally from Poland, and my chem teacher was from Iran, but hearing scientific concepts explained in a strong non-Midwestern accent makes me remember his lectures.
