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.
