Book excerpt: Papers on Unmatter, Harmonic Quantum Oscillators, Vacuum Polarization, Scale-Invariant Models, Superluminal Reference, Heuristic Model and so on. “Angel particle” bearing properties of both particles and anti-particles, which was recently discovered by the Stanford team of experimental physicists, is usually associated with Majorana fermions (predicted in 1937 by Ettore Majorana). In this message we point out that particles bearing properties of both matter and anti-matter were as well predicted without any connexion with particle physics, but on the basis of pure mathematics, namely — neutrosophic logic which is a generalization of fuzzy and intuitionistic fuzzy logics in mathematics.
