Interacting with hardware is on another level. I remember taking some introductory hardware level classes, and we began to simulate our circuits, just combinations of gates and what-not and you hit a weird signal pattern.... "Ohh, that's just a gate-glitch, we'll discuss that in later courses!" The way that physics interacts with hardware is incredible, and the dance that we all do back and forth between hardware and software really strikes me as magical. I love it.
