“Weinberg, whom Oppenheimer had come to regard as one of his brightest students, observed that mathematical formulas were like temporary hand-holds for a rock-climber. Each hand-hold more or less dictates the position of the next hand-hold. “A record of that,” Weinberg said, “is a record of a particular climb. It gives you very little of the shape of the rock.”
