The present theory of elementary particles is unsatisfactory because there is no unifying law to explain the some 30 odd independent "elementary" particles. A qualitative discussion is presented on strong, electromagnetic, and weak interactions. A definite nuclear charge is ascribed to the proton, neutron, and hyperon that other particles such as the photon, neutrino, electron, and meson do not possess. One of the main theses of contemporary physics is that each kind of elementary particle has a corresponding antiparticle. The nonconservation of parity in weak interactions beta decay) is discussed, and the theory of Landau on the invariance with respect to the combined inversion is cited. All the particles can be arranged in two groups. One contains particles with a spin of one-half and the other contains particles with an integral spin (including zero). All known particles with a nuclear charge have a larger mass than the corresponding particle without a nuclear charge. Heisenberg-s "nonlinear field theory" and other mathematical theories that attempt to explain the physics of elementary particles are discussed in qualitative terms. (TTT)
