All around us, things are falling apart. The foam on our cappuccinos appears solid, but gentle stirring irreversibly changes its shape. Skin, a biological fiber network, is firm when you pinch it, but soft under light touch. Sand mimics a solid when we walk on the beach but a liquid when we pour it out of our shoes. Crucially, a marginal point separates the rigid or jammed state from the mechanical vacuum, freely flowing state – at their marginal points, soft materials are neither solid nor liquid. Here I will illustrate that the marginal point gives birth to a third sector of soft matter physics: intrinsically nonlinear extreme mechanics. I will discuss three examples of this: Shocks in Sand, Flow of Foams, and Elasticity of Marginal Networks.
