Recent developments in string/field theory suggest that strong interactions of hadrons in our four space-time dimensions may be described in terms of some weakly interacting fields that live in five dimensions, where the additional fifth dimension plays the role of the energy scale. In this approach, our quantum world appears as a holographic image of some classical five dimensional theories. Despite its simplicity, the holographic model is able to reproduce numerous very important features of QCD. Using this formalism, the results for some of the simplest hadronic form factors will be presented. A good agreement with experiment, suggests that this approach can be used as an alternative tool to study nonperturbative aspects of QCD.
