An electron-proton/ion polarized beam collider (EPIC) with high luminosity
and center-of-mass energy s​=25 GeV would be a valuable facility for
fundamental studies of proton and nuclear structure and tests of quantum
chromodynamics, I review a sample of prospective EPIC topics, particularly
semi-exclusive reactions, studies of the proton fragmentation region, heavy
quark electroproduction, and a new probe of odderon/pomeron interference.Comment: Talk presented at EPIC'99 Workshop, Indiana University, April 199
