I had a somewhat satisfying moment when my husband, an electrical engineer, offered to help me with a homework problem I was stuck on. (He is my go-to guy for helping me learn or relearn the more complex math and logic problems I encounter in my computer science courses.) I started to explain the homework problem, when he stopped me: “Wait, what is relational algebra?” I explained the general idea and the allowed operations, and he admitted, “Huh, I have never done that before.” As he wandered back to his own work, I turned back to my desk with even more resolve.
