supersymmetry - Do the Grassmann coordinates in the superfield formalism have any physical meaning?


In the superfield formalism we consider fields in a space who has four so called bosonic coordinates xν and four so called fermionic coordinates θ1,θ2,¯θ1,¯θ2.


xμ are of course the physical space-time coordinates, but, do the Grassmannian coordinates have an analog interpretation like some kind of extra dimension or should I view them as a mere formal artifact?

classical mechanics - Moment of a force about a given axis (Torque) - Scalar or vectorial?

I am studying Statics and saw that: The moment of a force about a given axis (or Torque) is defined by the equation: $M_X = (\vec r \times \...
