Children conduct their spontaneous explorations and experiments with naive perceptivity. They have an innate urge first subjectively to sort out, find order in, integratively comprehend, and synergetically memory-bank their experience harvests as intertransformability system sets. Thereafter they eagerly seek to demonstrate and redemonstrate these sets as manifest of their comprehension and mastery of the synergetic realizability of the system’s physical principles. Consequently children are the only rigorously pure physical scientists. They accept only sensorially apprehensible, experimentally redemonstrable physical evidence.
