Abstract
This review is based on lectures on physics given at TASI 2008. First I summarize our present knowledge on the fundamental parameters of the sector. Then I discuss various scenarios going beyond the standard model which attempt to explain aspects of the flavor puzzle. Relating quark masses and mixing angles via symmetry is explored. Explaining the mass hierarchy via the Froggatt-Nielsen mechanism is reviewed and illustrated. Grand unification ideas are pursued to seek a pattern in the observed masses and mixings of quarks and leptons. Generating light fermion masses as radiative corrections is explained and illustrated. The popular solutions to the strong CP problem are summarized. Finally, specific processes in B meson system where significant new contributions can arise are discussed.
