An engineer, a mathemtician, and a physicist where taken to a room wherein was a beautiful woman. There they were given these instrucitons: You may have your way with the woman, but you must approach her by increments of one-half of the distance each time. The matehmatician and the physicist immediately turned to leave saying that they could never reach her in this way. But the engineer immediatley began moving towrd the woman saying he could get close enought to make an 'engineering approximation'.
