Symmetry in Science
In this chapter we briefly review what science is about, and we see that it strongly involves reduction. It is shown that reduction is a symmetry. We consider three ways reduction is used in science: observer and observed, quasi-isolated system and surroundings, and initial state and evolution. Reproducibility, predictability, and reduction compose the triple foundation of science. The former two are shown to be symmetries and to imply analogies. Thus symmetry is of major importance in the foundation of science.
