noun: sound practical judgment
"Things are not always what they seem. Common sense, so very valuable in every-day life, goes but a very little way in science. Common sense could not have told that, when a uniform body is suspended at one end and oscillated as a pendulum, the oscillations would be the same if suspended at one-third from the end. Much less could common sense have told that suspension at a point between these two points, namely, at two-thirds of this one-third from the end, would give the highest rate of speed of oscillation of which the body is capable, a point which we shall call the center of Velocity."
