This is not Steven Rado, writer or reviewer, as has been explained already. Robert Louis Kemp cites Rado as one of his sources.
As for the physics in Kemp's book, the immediately accessible feature to me from the previews is the radical theism involved. It is not unlike Newton's radical theism, that God is an implementer of arbitrary mathematical designs, as well as an arbitrary puppet master when he wishes. You should consider the position of Spinoza and Leibnitz as an antidote to Newton's assertion of faith. They apparently came to an agreement that mathematical systems exist out there wherever they can because there is no mechanism for a cosmic censor to prevent it.
There are dubious things to be seen in the mathematics, but I did not slow down into crawl gear to prove my impressions. Why would there be an aether? Why are photons standing waves with only a fixed number of wavelengths? How can a photon overcome the dipole nature of its fields to become a polar charge when orbiting the location of the charge?
Naturally, I prefer my own manuscript on controversial physics.
