%0 Journal Article %T An Einstein-Cartan Fine Structure Constant Definition %A Stone R. A. Jr. %J Progress in Physics %D 2010 %I HEXIS (Arizona) %X The fine structure constant definition given in Stone R.A. Jr. Progress in Physics, 2010, v.1, 11-13 is compared to an Einstein-Cartan fine structure constant definition. It is shown that the Einstein-Cartan definition produces the correct pure theory value, just not the measure value. To produce the measured value, the pure theory Einstein-Cartan fine structure constant requires only the new variables and spin coupling of the fine structure constant definition in [1]. %K Einstein-Cartan fine structure constant %K General relativity %K fundamental constants %U http://ptep-online.com/index_files/2010/PP-20-L3.PDF
