Thank you very much for this answer. I was wondering how esoteric interpretation (1) actually is. But apparently (1) has already been falsified. I will take a look at Weinberg.

the Feynmann-Stuckelberg interpretation: a negative energy solution of the Dirac equation is interpreted (1) as a negative energy particle traveling backwards in time or (2) as a positive energy anti-particle going forwards in time. However, if a positron and an electron annihilate each other a...

"In statistical mechanics, a microstate is a specific microscopic configuration of a thermodynamic system that the system may occupy with a certain probability in the course of its thermal fluctuations. In contrast, the macrostate of a system refers to its macroscopic properties, such as its...

i know, but i could not come up with a better name for m.

if the observer moving with the stick measures the mass density as (rest mass)/(rest Volume) = m0/V0 and the stationary observer measures the mass density as (relativistic mass)/(contracted Volume) = m/V = γm0/V0/γ = γ^2 m0/V0 then mass density is (indeed) frame dependent. In my mind the two γ...

I would just say, according to that particular observer it is space itself that is contracted. Therefore everything is contracted, also the atoms in the stick. In both situations the stick contains the same amount of atoms with the same direction relative to each other and therefore there is no...
