  The kernels in the tangible matter of our everyday experience are composed of
light quarks. At least, they are light classically; but they don't remain
light. Dynamical effects within the Standard Model of Particle Physics change
them in remarkable ways, so that in some configurations they appear nearly
massless, but in others possess masses on the scale of light nuclei. Modern
experiment and theory are exposing the mechanisms responsible for these
remarkable transformations. The rewards are great if we can combine the
emerging sketches into an accurate picture of confinement, which is such a
singular feature of the Standard Model; and looming larger amongst the emerging
ideas is a perspective that leads to a Borromean picture of the proton and its
excited states.
