Why is SFT not a Lagrangian formulation?
The Maxwellian basis is much easier to work with in the same way
that the finite-difference method of numerical solutions is far easier
to implement than the finite-element method. It is more closely
linked at an intuitive level to the important role the photon plays in

of rotation, helix, spiral, etc.
What role do gauge and symmetry play in SFT?
Gauge theory is almost trivial in SFT, and as such there is little
need to consider gauge apart from recognising that each spinor
rotation is O(2) and non-unitary. When we consider two particles
we need to consider two field particles. In the atom this boils down

What does SFT mean for EM? (What is wrong with CEM?)
The usual method of obtaining relativistic fields is via the Lienard
Wiechert scalar and vector potentials. In other words, the fields
are determined by taking the distance between two charges. In SFT
this single distance is replaced by
two
distances taken between the
centres of the bi-spinorial rotations of the photon. In other words
there is not a single distance but two distances taken in measuring
the fields. This is discussed in Chapters 1 and 3.
What does SFT mean for quantum theory in its various
forms?
We need to differentiate between current implementations of
QM and post-SFT implementations. If we change the way the
