  • @jdalton4552
    @jdalton4552 4 дні тому

    This video is a wonderful exposition of how the neutrino problem indicates new physics. Larson's Reciprocal System postulates the three neutrino flavours as follows: The neutrino triple notation shows that the uncharged neutrino consist of both a magnetic and electric rotation and that collisions give these rotations a charge or rotational vibration. The magnetic charge is two dimensional and therefore takes 720% to complete compared to the electric vibration which is one dimensional and takes 360 degrees to complete. Larson explains that the uncharged neutrino is massless (because it has zero net displacement) and is carried by the progression as a form of radiation, but acquires mass from the magnetic charge which causes it to become trapped inside an atom whereby it imparts its magnetic charge to the atom as one unit of vibrational mass.

    Unfortunately, in general, neither symmetric nor ant-isymmetric wavefunctions can be said to be eigenfunctions of the Hamiltonian. The wave function for an electron in a hydrogen-like atom with atomic number Z in the ground state is RZ(r)=2(Z/a0)^(3/2)*exp(-Zr/a0). RZ(r) is an eigenfunction of HZ=1/(2m)*p^2-Ze^2/(4πε0r). But RZ(r) is not an eigenfunction of HZ'=1/(2m)*p^2-Z'e^2/(4πε0r), Z'≠Z. Let us consider the case where a hydrogen-type atom with atomic number Z and a hydrogen-type atom with atomic number Z' are sufficiently separated from each other. And each electron in each atom is in the ground state. The anti-symmetric wave function Ψ={RZ(r1)RZ'(r2)-RZ(r2)RZ'(r1)}/2^(1/2) is not an eigenfunction of the Hamiltonian H=1/(2m)*p1^2-Ze^2/(4πε0r1)+1/(2m)*p2^2-Z'e^2/(4πε0r2). It should be an ironclad rule of quantum mechanics that the wave function is an eigenfunction of the Hamiltonian.
