Query: On Some Physical Aspects of Planck-Scale Relativity:A Simplified
  Approach   The kinematics of the two-scale relativity theory (new relativity) is
revisited using a simplified approach. This approach allows us not only to
derive the dispersion equation introduced earlier by Kowalski-Glikman, but to
find an additional dispersion relation, and, even more important, to provide a
physical basis for such relations. They are explained by the fact that in the
observer invariant two-scale relativity (new relativity) the Planck constant
does nor remain constant anymore, but depends on the universal length scale.
This leads to the correct relation between energy and frequency at any scale.
