The twentieth century saw two great revolutions in physics: quantum mechanics and general relativity. Although both these theories have had great success in describing the physical world; the two theories are in fundamental conflict at a basic level. In this presentation, I will attempt to describe both theories and discuss this fundamental conflict between them. I will then briefly discuss some of the proposals of resolving this conflict. Finally I will show that virtually all theories of quantum gravity lead to some fundamental length scale which may be described via a modification of the uncertainty principle. I will conclude by examining some of the consequences of this generalized uncertainty principle or GUP.
