Dr. Christoph Caesar the model gives a correlation between spin and charge of the electron. The electron is a circulating electromagnetic wave with an internal twist as Moebius ribbon. the electron model is singularity free . The electron is a closed loop vibrating string comparable to string theory. The quark has a substructure and consists of 18 high energy electrons of 53 MeV each the nucleon is composed of 18 quarks of 53 MeV minus 16 MeV binding energy
