“This marvellous book describes a wealth of biological features in terms of the structure of the underlying dynamical space, its bifurcations, and its attractors. This dynamical space is parameterised (say by the frequency of a gait), and as the value of the parameter changes, the dynamics changes, sometimes significantly (such as changing from a trot to a gallop). Moreover, the change can also depend on how the...

Undeniably, imposing such divisions on space and time, wave and particle, order and chaos, action and perception, or organism and environment have enabled significant progress in our scientific understanding of...

J. A. SCOTT KELSO & DAVID A. ENGSTRØM – have written The Complementary Nature to summarize their research plan. In this book, Kelso and Engstrøm contend that ubiquitous contraries are complementary and propose a comprehensive, empirically-based scientific theory of how the polarized world and the world in between can be reconciled. They nominate the squiggle (~), as the symbolic punctuation for reconciled...
