The Electron

This book presents the modern quantum field theory view of the electron. This view is very different from the outdated classical view that is most often taught in schools and colleges. We cannot present the QFT view of the electron without also presenting the electron's sister particle the neutrino, and so the QFT view of the neutrino is presented also. The quantum physics equations which describe the electron and the neutrino are presented in a simple and clear way. The Dirac equation is rewritten using quaternions, and this leads to a resolution of the neutrino mass problem and to an understanding of why neutrinos are all left-handed. Thus we come to understand the violation of parity by the weak force and how neutrinos can both move at the speed of light and oscillate between generations. This book is a landmark book in this area of physics.
