 rimental and theoretical research on flat bands materials. When a system e
 xhibits flat bands despite having sizable hopping integrals/electron itine
 racy\, the flat band is likely to be topological. In stoichiometric materi
 als\, one now has flat band catalogues of materials exhibiting such electr
 onic states at the Fermi level. I will review the interacting and topologi
 cal physics of such bands\, first with simple one-body models and then add
 ing interactions to obtain Kondo physics\, magnets\, charge density waves\
 , and superconductors. In engineered moire materials\, where the Fermi lev
 el can be gate-tuned\, a new degree of precise controllability allows for 
 the development of flat bands exhibiting Chern insulators\, Superconductiv
 ity\, and - most recently - Fractional Chern insulators. We will show that
  the physics of most of these bands holds a close resemblance to heavy Fer
 mion physics.
