Guanine ~ Cytosine, Adenosine ~ thymine, two complementary pairs that are coexistent, dynamically inextricable. In Squigglespeak this situation is an example of a “Squiggle square”. Just two CP is sufficient to act as carriers of the genetc code…

Review of TCN

The Complementary Nature ~ A Review by Olaf Sporns “The division of our world (natural and social) into distinct contraries or opposites has become almost universal practice in most fields of human endeavor and inquiry, including science. 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 these separate domains. However, understanding based on separation or contraries is fundamentally limited, as is powerfully demonstrated by modern physics, biology and neuroscience. Kelso and Engstrøm’s book offers an alternative, synthetic view based on the principle of complementarity, the reconciliation of contraries as jointly necessary and mutually reinforcing aspects of reality. This volume not only presents a comprehensive history of the idea of complementarity, it also puts forth a theoretical framework, called coordination dynamics, within which complementarity is rooted. The originator of this framework and lead author of the book, Scott Kelso, is a world-renowned neuroscientist whose unique perspective on brain dynamics pervades much of the text. The dualist stance, epitomized in the writings of Descartes and his followers, has had a dominant influence on our modern conception of brain and mind as
