   Inertia is a consequence of conservation of energy.  Consider the   
   following argument:   
   -A particle of mass m_0 at rest has zero momentum and energy   
   E=m_0 c^2   
   -Quantum mechanically the wave function has frequency   
   \omega_0 = \frac{m_0 c^2}{\hbar}, and k=0.   
   -If you Lorentz transform to a moving frame with velocity beta,   
   the frequency becomes   
   \omega_1 = \omega_0 \gamma   
   and the wavenumber becomes   
   k = \omega_0 \gamma \beta   
   In other words, to promote an object at rest in one frame to   
   being at rest in a moving frame, you have to add energy.  This   
   is the experienced as "inertia", the tendency for objects to   
   remain in constant motion unless disturbed.  (By disturbed,   
   I mean energy is added or subtracted from the object.)
