Various ideas associated with exotic hadrons, and hadronic structure in
general, are briefly reviewed.Comment: 6 pages, Proceedings of Hadron201
Aspects of Confinement: a Brief Review
A brief and biased overview of the phenomenon of confinement in QCD is
presented in three parts: (1) the definition of confinement, (2) properties of
confinement, (3) ideas of confinement. The second part chiefly consists of a
brief review of recent lattice computations related to confinement while the
third summarizes some of the current analytical approaches to understanding
confinement. These include the Dyson-Schwinger formalism in Landau gauge,
Hamiltonian QCD in Coulomb gauge, and the vortex picture of confinement.Comment: 10 pages, 6 eps figures. Plenary talk at Hadron 2003, Aschaffenburg,

Molecular Interpretation of the X(3872)
The discovery of the X(3872) in the 3\pi J/\psi mode is compelling evidence
for its molecular nature. A successful prediction of this decay mode and other
predictions are reviewed here.Comment: 3 pages, ICHEP proceeding
Beyond the Constituent Quark Model
Modern experiment requires a reliable theoretical framework for low energy
QCD. Some of the requirements for constructing a new model of QCD are presented
here. Progress toward these requirements are highlighted.Comment: 10 pages, 5 ps figures, based on a plenary talk at Hadron 2001,
