On Feynman’s Speculations About the Origin of the Fine-Structure Constant

Authors: Lamont Williams
Comments: 2 Pages.

When thinking about the origin of the fine-structure constant, renowned physicist Richard Feynman speculated that it might be related to pi or the base of the natural logarithm. However, he could not envision how pi or the natural logarithm’s base could be associated with the constant. This article presents an equation that helps to address Feynman's question.

The Derivation of the Hertz-Kilogram Relationship Constant, via the Democritean Indivisible Particle / Unit, Y' and the Relative Ratios of the 13/12 Schematic

Authors: Vito R. D'Angelo
Comments: 7 Pages.

The Hertz-kilogram relationship constant, although obscure, is nonetheless a bona fide constant listed in the National Institute of Standards and Technology's (CODATA values) fundamental constants list[pg.6]. The Hertz-kilogram relationship constant is being used due to its value of (7.372497201 x10^-51 (91)) being very close to the Democritean indivisible unit, Y' (8.134865168 10^-54) It is shown that the 13/12 schematic of U-theory [2] theoretically calculates the fundamental constants within the uncertainty limits of (NIST) CODATA values [1]; utilizing twelve dimensionless constants.
