DESCRIPTION:Abstract.  Adding a single Cohen real 
 to L provides us with a lattice of intermediate mo
 dels, but if we only consider models of ZFC, these
  models are all somehow very similar (except L its
 elf). Without assuming the Axiom of Choice in thos
 e intermediate models we have a very different pic
 ture. We will discuss the construction of the Bris
 tol model, which is a model between L and L[c], wh
 ich does not have the form L(x) for any set x.
