We interact with practical applications of scientific knowledge, more commonly known as technologies, on a daily basis. We wake to an alarm clock, cook breakfast on a gas-powered or electric stove, and go to school by car, bus, or bicycle. We work on computers in lighted classrooms, complete our assignments using pen and paper, and perhaps watch television or listen to music before going to sleep.
