All arguments in textbooks and the research literature are based on classical logic. Nothing at all in quantum theory is deduced by...

Not quite. One still has to find the infinite sequence of invariant subspaces of the Hamiltonian, which gives rise to the triangular...

Try my book on algebraic quantum physics, it might convince you of the opposite!

Indeed, relativistic multiparticle quantum mechanics is consistent (and useful) but has, compared to relativistic quantum field theory...

In differential geometry, there is a covariant concept of a 4-vector, and the momentum vector is such a 4-vector. Only the coordinates...

1. Local and global symmetries are essentially different concepts. Electromagnetism has a local U(1) gauge symmetry that is essential to...
