This talk is an introduction to the classical lattice problems of sphere packing and covering in arbitrarily high dimensions, and the Siegel and Rogers integral formula developed in the 1940-50's to study them. They still remain as one of the strongest approaches to the family of such problems, and the records established back then remain unbeaten to this day. I present some past and recent works in the literature, as well as a few works of mine, that are in some sense reflections on the difficulty of these problems.
