We give a geometric construction of simple Lie algebras from the corresponding simple singularities. Milnor fibers of each simple singularities are rearranged to form, what we call, a Coxeter wheel, whose equivalence class of edges and diagonals can be identified with the corresponding root system of the Lie algebra.
We give a geometric definition of Lie brackets using elementary operations in singularity theory.
