Koide Formula Derived

https://en.wikipedia.org/wiki/Koide_formula

(((3e+8 * ((0.9 / ((0.5^0.5) / (pi / 4)))^2)) / c) / 3) * 2 = 0.666659497 s / m

(Area Skewed Circle ) / ( Area Sine Wave )

solve (0.9*π/(sqrt(0.5)*4))^2*2/2.99792458 = Kiode

solve (3^4/2^2*pi^2/299.792458) = Koide

0.6666594965576469306355880465394898643184092809854009

solve 1/(3^4/2^4 * pi^2 * 299792458 ) = 6.67597213749e-11

solve (3^4/2^2*pi^2/299.792458) = Koide
