  In this talk I present a summary of recent work on tunnel junctions of a
fractional quantum Hall fluid and an electron reservoir, a Fermi liquid. I
consider first the case of a single point contact. This is a an exactly
solvable problem from which much can be learned. I also discuss in some detail
how these solvable junction problems can be used to understand many aspects of
the recent electron tunneling experiments into edge states. I also give a
detailed picture of the unusual behavior of these junctions in their strong
coupling regime. A pedagogical introduction to the theories of edge states is
also included.
