“So a scientist and an engineer are tossed into separate rooms, stocked with tools and parts, and told that they aren't allowed out until they've produced a working prototype for a radio receiver. After two days, the scientist has covered the walls in scribbling and looks like a mad man, raving about how not only is it impossible to build a receiver with the parts given but that he's proven that radio is theoretically impossible anyway. When they check on the engineer, they find that he'd built the receiver in less than a day, fashioned a crude speaker and antenna, and had found a radio broadcast he liked and hadn't bothered to tell them he'd finished.”
