gamma = 1/cosine(A) - 1
where cosine(A) is the cosine of the angle whose sine is velocity(A)/C.
The velocity/C sine function is called beta and also the fine structure constant.
Considering that the velocity of electro-magnetic propagation in a medium is a function of the product of the permeability and permittivity of the medium,
