"Most of science is a search for simple, stable properties that can answer questions which interest us. We sometimes speak of these as emergent properties. … Finding useful emergent properties, and learning to use them skillfully, can be big achievements. The hard sciences have over their history produced many important emergent properties (entropy, chemical bond, stiffness, and so on) and built many useful models based upon them."
