Explore the fascinating properties of clay through this physics lecture that examines whether clay behaves as a solid or liquid material. Delve into the complex rheological properties of clay and other soft matter systems, investigating how materials can exhibit characteristics of both solid and liquid states depending on conditions. Learn about the fundamental concepts of non-Newtonian fluids, viscoelasticity, and the physics behind materials that challenge traditional classifications of matter states. Discover how clay's unique molecular structure and particle interactions create its distinctive behavior under different stress conditions. Examine experimental approaches used to characterize such materials and understand the theoretical frameworks that explain their dual nature. This lecture forms part of the Summer School for Women in Physics 2025, designed to encourage women to pursue physics careers through hands-on experiments and theoretical discussions that highlight the excitement and interconnectedness of physics concepts.
