Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Planck (1906a) akarondedzera mwero wokukurumidzira uye akapa ukoshi hwakarurama hwehuwandu hwekureba uye hwakatambanudzwa nokururamisa kukanganisa kuduku kweshoko rakapiwa naEinstein muna 1905. Mashoko aPlanck akanga akaenzana neaya aishandiswa naLorentz muna 1899. Zvichibva pabasa raPlanck, pfungwa ye relativistic mass yakagadzirwa naGilbert Newton Lewis naRichard C. Tolman (1908, 1909) nokurondedzera mass sechiyero che momentum kune velocity. Saka tsanangudzo yekare yemuchinjikwa uye yemuchinjikwa, umo muchinjikwa waitsanangurwa sechiyero chesimba nekumhanyisa, yakava isina basa. Pakupedzisira, Tolman (1912) akadudzira uwandu hune chokuita noupenyu hwomunhu seuwandu hwomuviri. Zvisinei, mabhuku akawanda emazuva ano anotaura nezvoruzivo rwokuzvarwa narwo haachashandisi pfungwa yokutaura nezvoruzivo rwokuzvarwa narwo, uye ruzivo rwokuzvarwa narwo rwunofungidzirwa sechinhu chisingachinji.  Mubvunzo: Chii chakava chisina basa?
