I have been reading lately about the stability of dynamic systems and I found the results at first very strange. It says that an equilibrium of a system is stable if and only if all of its corresponding eigenvalues have negative real parts. The word eigenvalue etymologically comes from the German 'Eigenwert' and means intrinsic value. I was wondering, how could a person be stable if all its intrinsic values are negative? I always thought that stability was related to positive appreciation about one's own worth i.e. own eigenvalue! After a while, I discovered that I was shortsighted and that the mathematical statement were very deep for my superficial understanding.
