Summary
In this chapter, the notion of partons is introduced. Evidence of the substructure of the nucleon is given, and the formalism of the deep inelastic scattering is presented. The form factors and the Bjorken scaling properties are explained in detail. Finally, the parton density functions are presented, and the chapter concludes with the open question of the origin of the proton spin.
