, 06:32, August 25, 2010→Different values of Inertia: Lorentz discovered what he called the longitudinal and transverse mass
For counter-example 19, I'm not quite sure I understand. The value of the inertial mass (m) is constant for a given physical body undergoing any sort of motion, whether parallel or perpendicular to the observer's motion. I don't want to remove this as an counter-example to relativity before I understand what the author meant. Could this be clarified for me? Thanks.

: The rest mass is the same. I think Lorentz discovered what he called the longitudinal and transverse mass in around 1900. It was experimentally testing in around 1902. Einstein uses similar terminology in his 1905 paper. [[User:RSchlafly|RSchlafly]] 02:32, 25 August 2010 (EDT)
