Book

This monograph offers a full account of the nature of gravitation. It is shown to be an electrodynamic action due to the disturbance of the vacuum medium by matter. A link with the existence of elementary particles is presented. The approach is verified by the exact evaluation of the constant of gravitation G in terms of the charge-mass ratio of the electron. The masses of the muon, pion and proton are also evaluated in relation to the electron mass. - From the Preface
