What is the best way to pack congruent copies of some shape in n-dimensional Euclidean space? This important question in geometry presupposes that there is a rigorous notion of what it means for a packing to be "best". Certainly a best packing should have maximum density, but this condition is not enough. Defining optimality of packings (and coverings) is a subtle matter, and I will discuss how ideas from topology, dynamical systems, and measure theory help clarify it.
