Aphysical Quantum Mechanics as a deeper quantum theory has resulted in immediate foundational transformation of particle physics, including discovery of 3D inner structures of perfect geometry for each class of elementary particles and the explanation of the origin of their self-mass. The electron is not a fundamental fermion as claimed by the Standard Model. The electron is a composite fermion, consisting of the intrinsic electron and the electron neutrino. The electron neutrino is a duo-fermion. The electron neutrino inner structure consists of intrinsic neutrino with negative weak electric charge and intrinsic antineutrino with positive weak electric charge of opposite helicity, thus preventing electron neutrino from its self-annihilation. Electron neutrino self-mass and weak electric charge are determined with the precision of five digits. Electron neutrino self-mass is equal to 296.118 828 eV. This is one of the greatest triumphs of Aphysical Quantum Mechanics.
