(Phys.org)Many biological systems involve dense packing of a large amount of fabric or particles in a confined space. For example,eukaryotes' nuclei hold about two meters of DNA that is tightly wound into chromosomes. On the larger scale pharmaceutical packaging, manufacturing, and transport all involve trying to pack the most amount of fabric within a small space. Furthermore,nanotechnology and fabric sciences are concerned with particle packing and layering. While the concept of packing the most amount of fabric in a small space is simple, understanding how particles of various shapes pack is not.
