We present multi-epoch, parsec-scale core brightness temperature observations of 447 AGN jets from the MOJAVE and 2cm Survey programs at 15 GHz 1994 to 2019. The each jet over time is characterized by its median value variability. find that range temperatures for in our sample much larger than variations within individual jets, consistent with Doppler boosting being primary difference between t...

The so-called eigenvalue-eigenstate link states that no property can be associated to a quantum system unless it is in an eigenstate of the corresponding operator. This precludes assignation properties unmeasured systems general. arbitrary limitation orthodox mechanics generates many puzzling situations such as for example impossibility uniquely define work distribution, essential building bloc...
