Toward a fundamental mechanics. II

A beta structure hypothesis is advanced, according to which all matter and the vacuum are composed solely of electrons. A direct connection is established between beta processes and nuclear forces. Physical implications of the formalism introduced in Part I are examined. Localized violation of the Heisenberg postulate opens extensive descriptive possibilities inaccessible to current field-derived theories. A weakness of the present attempt at ''elementary'' particle description is its incapacity to predict observed masses or spatial extensions. This results from the particular (one-body) model employed, which posits an infinitely massive point ''force center.'' Improvements in the formulation of the relativistic many-body problem will be required to correct this shortcoming. In summary, the investigation reaffirms the logical sufficiency (surmised by Newton) of the elements of mechanics for describing the phenomena of nature
