Facts are the air of the scientists. Without them you never can fly. |
Perfect as the wing of a bird may be, it will never enable the bird to fly if unsupported by the air. Facts are the air of science. Without them a man of science can never rise. |
School yourself to demureness and patience. Learn to inure yourself to drudgery in science. Learn, compare, collect the facts. |
While you are experimenting, do not remain content with the surface of things. Don't become a mere recorder of facts, but try to penetrate the mystery of their origin. |
