Understanding the physics of how molecules or objects put themselves together
Physical laws for making compromises
Questions about how organization and order in various systems arises have been raised since ancient times. The forms we identify around us are only a small sub-set of those theoretically possible. So why don't we see more variety? To answer such a question is the reason why we study self-organization and self-assembly.
The essence of self-assembly is that system structure often appears without explicit involvement from outside the system. Organization results from interactions among the components and can evolve in either time or space, maintain a stable form or show transient phenomena.
Many natural systems show organization (e.g. galaxies, planets, chemical compounds, cells, organisms and societies). We approach the subject by looking for system properties applicable to all such collections of parts, regardless of size or nature. We will consider also dynamic changes that occur over vast numbers of time steps and on various length-scales.
In this course, we will discuss general rules about growth and evolution of structure, the forms it may take, and methods that predict changes in organization due to changes made to the underlying components.
