Consider how the microwave was invented, for example. Perry Spencer didn’t sit around the house, drumming his fingers and pounding his forehead, thinking, “How, how, how can I invent a device that will revolutionize kitchens around the world?” Spencer, an engineer at Raytheon, was at work one day when he left a candy bar too close to some radar equipment. The snack melted, and he asked himself, “Why would radar have this effect on food?” This small question led to answers that led to other small questions whose answers eventually changed how you and I make dinner.
Very good
