The lecture finishes the development of Grassmann numbers with the introduction of integration and differentiation.   With these tools in place Prof Susskind describes a simplified supersymmetric model.

Topics: 
  • Grassmann differentiation
  • A supersymmetric Lagrangian
  • Creation and annihilation operator based symmetry generators
