The Conference celebrated the tenth anniversary of Maldacena's conjecture, which is of paramount importance to the understanding of the relation between Quantum Field Theory, Supergravity and String Theory. Theoreticians who played a seminal role in the development of these ideas lectured at the conference. Twenty five speakers encompassing different directions and applications of the gauge/gravity duality discussed its achievements and future prospects. The aim of this volume is to make accessible to a larger audience the topics covered during the conference. The main applications of the conjecture concern high energy physics; however, aspects of cosmology and condensed matter physics are also relevant and included. Forewords by Gerard 't Hooft, Alexander Polyakov and Edward Witten further enrich the contents of this volume.
