What determines how grains such as sand pack together to fill a space? A thoroughgoing investigation of how geometry and friction interact in such systems is a step towards a more general ...

To understand these observations, we consider the packing problem from the granocentric point of view of a single particle in the bulk, exemplified by the particle marked by a star in the confocal ...

Researchers show that, unlike the crystalline close packing of spheres, random close packing or jamming of spheres in a container can take place in a broad range of densities and anisotropies.
