The Alexander polynomial is a classical (1923) invariant for knots and links, and can be defined in a number of different, elementary ways. Link Floer homology is a less classical invariant for knots and links, and ‘categorifies’ the Alexander polynomial. I will try to give one definition of the Alexander polynomial, and hint at how one defines knot Floer homology and sees that it categorifies the Alexander polynomial. Time permitting, I will discuss how we might ‘glue’ things together in both settings
