DESCRIPTION:The fractional quantum Hall fluid is one of the most nontrivia
 l strongly interacting fluids of nature. Many phenomena occurring in this 
 fluid can be explained by postulating a new type of quasiparticle - the co
 mposite fermion.  I will describe the new "Dirac composite fermion" theory
 \, which has provided a simple solution to some\nlong-standing puzzles and
  at the same time has stimulated the discovery of a large number of new du
 alities between quantum field theories in (2+1) dimensions. I will also de
 scribe physical consequences of the new theory.\n\n\n
