Well the masses are not derived out of no where, the article states: "The
predicted masses were claimed to have been derived by Heim using only 4
parameters - h (Planck's
G (Gravitational constant<http://en.wikipedia.org/wiki/Gravitational_constant>
), vacuum permittivity <http://en.wikipedia.org/wiki/Vacuum_permittivity>
 and permeability<http://en.wikipedia.org/wiki/Permeability_(electromagnetism)>

Great!  I'm glad it helped.
