When I was a physics student, my father started giving me mechanical pencils. You’d think all possibilities would have been invented by the 1980s. But some of these pencils were incredible feats of engineering with fun new ways to click out and retract the pencil graphite. I think my father had a point that there was always more to be invented, even for something so simple. We'd frequently look at bridges and discuss ways that they could be designed differently to distribute the weight and talk through the engineers' decisions around the common designs around us in the real world. Every time I'd invent something new, I'd diagram it for him with my pencils and he'd ask probing questions about the design choices I had made. One day, for instance, I’d invented a "Runner’s Ratchet Shoe." I was an avid runner in those days and would get sore knees and shin splints. The Runner's Ratchet was a set of levers attaching to the runner's ankle that would put t...
