Dear Michael, Your reply added two important statements about ##m(v)## which were missing in my original thread, namely: 1) the inconsistent and illegal attempt to keep for the relativistic particles the non-relativistic definition of momentum ##p=mv##; 2) the emotional personal reason...

Cheers, Zz! It is nice to see on this thread people who can explain more clearly than I can how the term mass should be used. As for the lengthy article by Wilczek, it is obviously lacking references to the papers of Steve Weinberg on masses of hadrons. Best regards Lev

It is more consistent to use the term mass for both massive and massless particles than to use the term rest mass for massless particles, which are never at rest.

The term "mass" is the source of many conflicting opinions among the authors writing on relativity theory. Different authors denote by this term different concepts. Quite often even the same author denotes by mass different concepts in his different writings. For instance when introducing...
