		| Abstract: | 
		All quasar spectra show the same atomic features in the optical, UV, near-IR and
 soft X-rays over all of cosmic time, luminosity black hole mass and accretion
 rate. This is a puzzle.  Here I show that it is possible that all of these
 atomic features can be accounted for by gas from an accretion disk driven the
 three forms of radiation pressure: electron scattering, line driving and dust
 driving.  The locations where they successfully drive an escaping wind, and
 those where they produce only a failed wind are both needed. |
