numerology has no value. The correct name is arithmology which come from arithmos(number) and logos(reason, speach, ratio). They both encode the fine structure constant just with different mathematical constants:
ARIThMOS(number) = NOMOS(law) = MAThHMATIKA(mathematics) = KAThOLIKOS(universal) = EYThEIA(straight) = LOKsOS(slanted) = DARDANOS(Dardanus) = ORNIS(bird) = PETAGMA(flight) = 430
pi / a = 3.14159 x 137.03599911 = 430.51
Kafre pyramid half base perimeter = 430.524 m
AThROISMA(sum) = MAKROS(length) = MARKOS(Markus) = PRISMA(prism) = 431
LOGOS = BAROS(wheight) = SEIRHN(siren) = 373
GP half base length = 373 photon feet
The link you posted has nothing to do with arithmology.
