1. Within the framework of a Hilbert space for an atom one cannot find an observable in the sense of ''self-adjoint Hermitian operator'' that would describe the measurement of the frequency of a spectral line of the atom. For the latter is given by the differences of two eigenvalues of the Hamiltonian, not by an eigenvalue itself, as Born's rule would require. 2. The measurement of a Z-boson is not a simple, essentially instantaneous act as the Born rule would require but a complex inference from a host of measurements on decay products. That the Born rule is used implicitly to derive the rules for working with an S-matrix does not make it applicable to the measurement of a Z-boson itself. 3. Electric field operators ##E(x)## are not Hermitian operators to which eigenvalues could be associated but oerator-valued distributions. Thus Born's rule cannot even be applied in principle. The measurement of an electric field already involves an averaging process and really measures an expectation, not an eigenstate. And this is already needed to explain why we can measure electric fields.
