  This paper is directed to the readers who are familiar with the earlier
papers by the author on the topic of mass-energy equivalence. A number of
important questions about the total energy equation H=mv^2 and its implications
are answered qualitatively. The relationship between the equation H=mv^2 and
the 4-vector (Minkowski) representation of Special Relativity is discussed in
detail. Other issues, such as de Broglie's original formulation of wave
mechanics, are also discussed.
