Structural Stability and Rene Thom came to my attention due to my work in Catastrophe Theory (I encountered it during my second (? third? maybe even fourth?) time through college and it has stayed with me ever since). This is a serious math book (although sometimes I wondered if I was reading fiction, to be honest) and I don't recommend it for anyone unless they've got a good foundation in complexity and topology. But if you do, my god what a read! The translation of information to form is itself worth the time it takes to read.
Just the sheer wealth of inventiveness and insight in this book is mind boggling. You'll want to be at least somewhat familiar with some topology and functional analysis to read this, but holy hell is it worth it.
This classic offers an unusual and intuitively appealing framework for thinking about morphogenesis, clearly inspired by D’Arcy Thompson. Its perspective is markedly different from standard treatments and, at its best, can be genuinely inspiring.
However, the scope is restricted to animals, with little engagement with plant development. The treatment of developmental mechanisms is qualitative, with minimal mathematical formulation, no predictive framework, and no validation. The discussion remains largely phenomenological, which is both its strength and its limitation.
Unfortunately, the prose is often cryptic, redundant, and occasionally hand-waving, making the argument hard to follow and leaving the reader unclear on the ultimate conclusion. As such, the book serves more as a suggestive starting point than a definitive treatment.
