If I were a pedant I'd say the title should be "moving atoms, not electrons," because there's nothing non-physical about what we're doing on computers. Still, the difference is noteworthy. "Robots, game controllers, Internet of Things, and more are ways that computer science interacts with physical objects and not just pixels on a screen. These are ways that teachers can bring more students to more interesting (to the student) to get involved with computer science." Maybe there should be a whole thing, 'computing with your hands', or something like that. Image: IBM, using atoms as pixels.
