The book "Material Inhomogeneities and their Evolution" by Marek Elzanowski offers a comprehensive examination of the theory of inhomogeneity, which has its roots in the theories of continuous distributions of dislocations and metal plasticity. It highlights the role of configurational or material forces in phenomena such as growth and reshaping, providing significant impetus to current research. This monograph adopts a differentiated-geometric approach to the theory of inhomogeneity and presents new results and perspectives based on ideas that the author has developed over the past two decades in various publications and presentations. The book is divided into three parts, with the first part entirely focused on the theory in the absence of evolution and addressing the geometric characterization of material inhomogeneity in simple bodies. It is a standalone work that does not aim to provide a historical overview or a comprehensive picture of the various schools of thought.
