In this talk I am going to present recent results obtained in collaboration with L. Erdoes and H.-T. Yau concerning the derivation of a certain cubic nonlinear Schroedinger equation, known as the Gross-Pitaevskii equation, from first principle many body quantum dynamics. With respect to previous results, we can now relax the smallness condition on the interaction potential.
