# From “Conservation” in Classical Physics to Solitons in Particle Physics

Chapter

## Abstract

The general concept of conservation in nature has not yet been well understood. On one hand, all evidence supports the idea of conservation of certain things and the growth or decline of some others. For the former we speak about *conservation* equations, for the latter on *balance* equations. On the other hand, conservation, in its broadest sense, includes unresolved physico-philosophical problems.
