PCT, Spin, Lagrangians

This is the first part of a paper, in which I invite you to take a step aside current quantum field theory (QFT): QFT has been said to be ”well-established” since the 80’s of the last century by its foremost theorists (see: [10, p.iv]), and the majority of physicists consider it to be essentially complete since the discovery of the Higgs particle. It will be interesting to see, what that really means: What are the problems left over to the younger generations? I’ll show you that a.o. it fails in its Lagrangian formalism, its postulate of positivity of energy, I’ll show the uselessness of the uncertainty principle as to electromagnetic fields, and we’ll see that there are serious doubts as to its conception of the photonic nature of electromagnetic fields, which a simple experiment could test against.
