Models are abundant in virtually all branches of physics, with some achieving iconic status. The Hubbard model, celebrating its golden jubilee this year, continues to be one of the most popular contrivances of theoretical condensed-matter physics.
Deep inelastic scattering — using a twenty-first-century electron–hadron collider of sufficient energy and intensity — could teach us much more about nuclear matter at the smallest resolvable scales, as well as add to our understanding of the Higgs boson and to the search for physics beyond the standard model.
