Letter from Albert Einstein to Lincoln Barnett, 19 june 1948. ‘’ it is not good to introduce the concept of the mass M =m/( gamma)^0.5 of a moving body for which no clear definition can be given. It is better to introduce no other mass concept than the ‘rest mass’ m. Instead of introducing M it is better to mention the expression for the momentum and energy of a body in motion.’’
Is that saying not to use relativistic mass?
