On Erdos' unit distances problem

One of the oldest and most popular problem in combinatorial geometry is Erdos' unit distances problem; What is the largest number of unit distances determined by n points in the plane. The best known upper bound - which is still far from the conjectured value - is more than 30 years old. In this talk I will explain why is this problem so difficult and what are the possible ways to attack it.
