Hadrons are incredibly complicated, tightly-bound state of quarks and
gluons, held together by the strong interaction of QCD. This makes
studies of hadronic matter fundamentally different from other bound states
(atoms, nuclei, molecules), as the basic starting point is no longer the
simple picture of free and easy-to-study constituents bound by relatively
weak forces. Because of this, studies of QCD typically focus on the quark
sub-structure of hadrons, giving the proton an important dual role as both
the most accessible bound state of QCD, and one of the ``fundamental''
building blocks of matter.
I will present some novel pictures of QCD and hadronic structure, discuss
how these influence the way we think about the proton and how it guides
our thinking in designing electron scattering measurements to study
hadronic matter.
