Details:As Napoleon knew, the best way to arrange cannonballs is in a Hexagonal Close Packing structure. However, there are situations in which other configurations are more favorable (for both cannonballs and colloidal particles!). I will explain which situations are these, demonstrate that they are indeed more compact than the HCP, and show you that these features are found in other type of systems.Pawel Pieranski et al., Phys.
