Derivation for length contraction and time dilation formulas for arbitrary transformations between inertial frames.

Use Euler-Lagrange formalism to determine the proper and coordinate acceleration for a gravitational field

Equivalence principle , time dilation due to relative accelerated motion vs. time dilation due to gravitational field gradient.

This is the most general formula for arbitrary relative orientation of [b]F[/b] and d[b]r[/b].

This document gives the correct definitions and comptations for proper acceleration. This is valid for translation ONLY. You cannot use the expressions for rotation.
