Video: Professor Noble introduces 'The Language of Symmetry' (IAI Academy, excerpt dur. 2'36")
The Language of Symmetry Edited by Rattigan, Noble & Hatta
‘The Language of Symmetry takes the reader on a fascinating interdisciplinary tour of the various different ways in which both classical symmetry and the order-chaos dichotomy are understood to apply in hugely diverse contexts… The book makes it abundantly clear, and in an engaging manner, that a synergy and even an interdependency between order and chaos underlies many aspects of the Universe.’ Peter L Read, Emeritus Professor of Physics, Oxford University
‘This is, without doubt, a stimulating and challenging book. It presents novel (even outrageous) concepts and produces evidence to support them. It challenges some of our mostly deeply embedded notions of how nature works at all levels… A brave attempt to elevate the ideas of order, disorder, and stochasticity to the level that they deserve. This is a book to be read and re-read slowly and to be thought about deeply.’ Ken Peach, Emeritus Professor of Physics, Oxford University
‘A remarkable book that releases an intellectual depth charge. It will go bang but there will need to be time and exposure to know what submarines it hits and what flotsam and jetsam float to the surface as a result… There is an almost comic degree to which a tiny book review can’t convey what has been achieved here.’ QUAD: The Oxford Alumni Journal

Edge of Chaos: Unveiling Life’s Hidden Symmetry
Why do so many systems we care about – from hearts and minds to markets, classrooms and democracies – only seem to work well in a narrow band between rigidity and disorder? In Edge of Chaos, writer and theorist Benedict Rattigan introduces Edge theory, a framework for noticing how stability and variability must continually hold each other in check if systems are to stay alive and able to change.
Drawing on vivid scenes from intensive‑care units, trading floors, protest squares, family kitchens and climate‑stressed coasts, Rattigan shows how the same deep pattern recurs in very different settings. Hearts fail when they become too regular or too erratic; institutions hollow out when rules crush dissent or when power spills into the streets; organisations lurch between bureaucracy and drift.
This is not a book of equations or management slogans. It is a patient, humane exploration of what it means to live and govern at the edge, where systems can still adapt without coming apart. Edge of Chaos gives readers a new way to think about resilience, risk and responsibility in a world that refuses to sit still.

Forthcoming publication: Beyond the Edge: The Counterplay Behind Everything That Lasts
Imagine a universe of perfect order, where nothing ever happens. Now imagine one of pure chance, endlessly busy but unable to hold a shape. Both are barren. Everything we care about lives between them: stars that burn for billions of years, hearts that keep time without becoming metronomes, cities that keep their character while everyone in them changes. In 1948 Warren Weaver called this middle ground organised complexity. Science still has no agreed account of what orders it.
In Beyond the Edge, Rattigan proposes one: the Counterplay Ratchet. Lasting things are made by opposing forces, one pushing and one holding back, that never quite defeat each other. Kept in motion and held within limits, their contest throws up new forms. Most fade. Those that hold up become the limits for the next round, so order builds step by step. That may be how chemistry became life, and habits became a self.
Beyond the Edge is a bold search for the ordering principle of organised complexity, in a world that makes new things by keeping its contests unfinished.
