Synthesized answer
The passages indicate that dynamical complexity tracks how systems change over time and can be "carved" in multiple ways, each revealing different patterns [3]. This directly impacts scientific explanation because, as passage 1 notes, a system composed of many interacting parts can be "fruitfully redescribed in the language of another science" [1]. For example, the human body can be explained either as an individual (evolutionary biology) or as a collection of cells (cellular biology) [1]. Thus, understanding dynamics shaped by many interacting components would lead us to construct explanations that are not single, static accounts, but rather a family of complementary explanations, each tied to a different "carving" of the system's configuration space.
This shift also changes how we evaluate explanations. Dynamical complexity provides a "physical interpretation" of mathematical complexity tools and can serve as a framework for thinking about "theories, explanation, and lawhood" [2]. It suggests that a good explanation is one that makes salient informative time-evolution patterns from a particular perspective [3]. Evaluating an explanation would therefore involve assessing which…

From the book
nce of many parts in a complex system, but also the fact that those parts interact with one another in a particular way. This is an insight that is clearly incorporated into dynamical complexity: since dynamical complexity deals with the number of different ways of carving configuration space that yield informative time-evolution patterns for a given system, the presence of interacting constituent parts is indeed, on this view, a great contributor to complexity. Why? Well, what does it mean to say that a system is “composed” of a large number of interacting parts? It means (among other…
formation-theoretic objects (signals, for instance) rather than the physical and social systems studied by scientists. Dynamical complexity, a concept articulated in detail in the first third of the dissertation, is designed to bridge the gap between the mathematics of contemporary complexity theory (in particular the formalism of “effective complexity” developed by Gell-Mann and Lloyd [2003]) and a more general account of the structure of science generally. Dynamical complexity provides a physical interpretation of the formal tools of mathematical complexity theory, and thus can be used as…
ical complexity is that complexity, at least as it concerns science, is a feature of active, changing, evolving systems. Previous attempts to define complexity have overlooked this fact to one degree or another, and have tried to account for complexity primarily in terms of facts about the static state of a system. Dynamical complexity, on the other hand, tracks facts about how systems change over time, and (moreover) embraces the notion that change over time can be tracked in numerous different ways, even for a single system. If our account of science from Chapter One is right—if science is…
verall. Chapters Two and Three taken together are primarily a contribution to the foundations of complex-systems theory. Building on the account of science from Chapter One , I argue that the traditional bifurcation of science into physical and social sciences is, at least sometimes, misleading. I suggest that we should also see some scientific problems in terms of a distinction that cuts across the physical/social science division: the distinction between complex-systems sciences and simple-systems sciences. After reviewing some of the attempts to define "complexity" in the (relatively…
ic quantum mechanics, for instance, still hasn’t been answered to the satisfaction of either philosophers or physicists. Philosophical attention to the measurement problem in the mid-20 century led directly to the overthrow of the Copenhagen Interpretation, and (more recently) to work on decoherence and einselection (e.g. Zurek [2003]). For an accessible survey of some of the ways in which philosophical thinking has contributed to physics in the 20 century, see Maudlin (2007). For examples of excellent current work in these areas, see Wallace (2011) and (2009), as well as Albert (2000). ↑…
More questions about this book
- How does Lawhead's concept of "dynamical complexity" specifically address the limitations of existing complexity definitions by providing a "physical interpretation" for physical and social systems, rather than just "information-theoretic objects"?
- If climatology is a "paradigmatic complex systems science," how might the dissertation's title, "Lightning in a Bottle," metaphorically capture the inherent challenges or ambitions in understanding and modeling such a system?
- Given the statement that "climate model families are significantly more diverse" than in other sciences, what specific implications does this diversity have for validating climate science models and building trust in their projections, especially concerning foundational questions about reliability?
- Lawhead identifies "What makes a system complex?" as a foundational question. How does the description of complex systems having "many different components operating at many different temporal and spatial scales" differentiate them from merely "complicated" systems, and why is this distinction crucial for scientific inquiry?
