Abstract
We discuss various aspects of the shape of the granular piles. First we present the experiments of Yan Grasselli measuring angles of repose under various conditions. Then we introduce a model for the angle of repose based on the restitution coefficient and an energy barrier which can be solved. After that we make some remarks on segregation and stratification. Finally we discuss the logarithmic tail of a heap on a table and in a silo. We present experimental results and a theoretical derivation using translational invariance.
