Title: Top Quark, The Teenage Years

Abstract: The top quark has been discovered ten years ago at the Tevatron Collider at Fermilab. The study of the top quark properties has been hampered by the small data samples collected by CDF and D0 at the Tevatron. However, a new era of high-statistics top quark physics is just starting and full reconstruction of top decays will be pivotal. New algorithms used for the identification of multiple b-quarks have recently been developed at CDF and are being used in the top quark analysis. In this talk, I describe the latest measurements of the top quark pair-production cross section and top mass measurements at CDF using these algorithms. I will finish with some prospects for the LHC where millions of top quark events will be collected.
