Where is inertia coming from?

Newtons experiment with a vessel shows how much he wished to find an explanation of the centrifugal force. The body in rotation was water; each part, even the smallest, of the water has the property of withstanding the centripetal force; so, the cause of inertia lies in the elementary particles. Electrons and quarks have a rest mass, but can it be represented by Einsteins equation, that contains a frequency? Indeed, how can an electron at rest vibrate or rotate? According to Zisman, or Feynman, electrons can move along the time axis. In the time, why do they not rotate perpendicularly to the 3D-space? It could be the cause of inertia. The same could hold for each of the three quarks of a proton or neutron, as it has an angular frequency. So we propose that matter, because it is made of electrons and quarks, is submitted to centripetal forces and for this reason has inertia and mass. We mention some consequences of this new idea.
