Eigen also points out that biological systems generally operate near what Kauffman
calls «the edge of chaos»» — that is, it usually happens that certain small changes will lead to disintegration of a quasi-species.
They probably use some of the terms he invented like [
eigen] function and various things like that; and some of his mathematics, for example, the equation with regard as the central driving equation of quantum theory, which we
call Schrödinger's equation, which governs the behavior of the subatomic matter.
