The previous 11 years have seen several breakthroughs in our understanding of topological states of matter. New Insulators and semimetals, exhibiting new properties imposed by a variety of symmetries (the most well known of which is time reversal) have been theoretically predicted and experimentally discovered. These materials are described by topological indices, a set of "serial numbers" that characterize the state of matter. In this talk, I will review the progress made in these years with a focus on the prediction of new topological indices and on material discovery. I will then show a surprising link between chemistry bonding and topological states of matter which leads to the prediction of many new classes of materials as topological.
