We discuss properties of non-Abelian gauge theories that change significantly
across the lower edge of the conformal window. Their probes are the topological
observables, the meson spectrum and the scalar glueball operator. The way these
quantities change tells about the way conformal symmetry is lost.Comment: 16 pages, 3 figures, contribution to Sakata Memorial KMI Workshop on
