  The behavior of mass is well known, as described by Newton's Laws of Motion,
the Lorentz Contractions, and Einstein's mass - energy equivalence. But just
what mass is, how those behaviors come about, what in material reality produces
the effects of mass, has been little understood.
  The only extant hypothesis is that of the "Higgs Field" and its related
particle, the Higgs Boson. Neither has been detected in spite of significant
efforts to do so. Further, that hypothesis is not so much a description of the
mechanics of mass as a further abstraction away from the problem by
substituting another field to explain what is not well understood.
  From a starting point of only the limitation on the speed of light, the
necessity of conservation, and the impossibility of an infinity in material
reality, the present paper presents a new and comprehensive analysis of the
phenomenon inertial mass:
  - how rest mass appears in particles,
  - how the Newtonian behavior arises from that, and
  - how the Lorentz Contractions operate in/on it, or, in other words, the
mechanics of inertial mass.
