What Does 'Fundamental' Mean?

Margaret Morrison (University of Toronto) In asking the question "What is fundamental about physics?" it is important to recognise that within physics itself the notion of fundamentality is less that clear cut. Although it has typically been associated with the study of high energy phenomena and more recently cosmology, there is reason to think this is no longer the case. We focus on the changing nature of "fundamental physics" and why the phrase is no longer the rigid designator it was thirty years ago. Using examples such as topological phase transitions we develop a notion of 'fundamentality' that can extend beyond the boundaries of physics.
