It is impossible accurately to determine, simultaneously, the exact location and the velocity of a moving object; any attempt at measurement of either inevitably involves change in the other. The same sort of a paradox confronts mortal man when he undertakes the chemical analysis of protoplasm. The chemist can elucidate the chemistry of dead protoplasm, but he cannot discern either the physical organization or the dynamic performance of living protoplasm. Ever will the scientist come nearer and nearer the secrets of life, but never will he find them and for no other reason than that he must kill protoplasm in order to analyze it. Dead protoplasm weighs the same as living protoplasm, but it is not the same.
