Did you catch all that? The original dust jacket of Hubbard's treatise on all things radiatory makes the claim that he is BOTH a nuclear physicist and a medical doctor. Both. But it could have happened, right?
Hubbard flunked out of the only course he ever took in nuclear physics. And because his grade point average was abysmally low, he eventually dropped out of college altogether. However he did get a degree from Sequoia University, an unaccredited college that apparently offered degrees in charismatic cult leadership.
But hey ... college degrees aren't everything. Look at Bill Gates, Michael Dell, most of the Cracked writers--all highly successful people who couldn't cut it in the classroom. Doesn't Big L. fit this category? He was a smart guy, right?
Not about nuclear physics, apparently. A 1965 Australian inquiry into All About Radiation ended with the scientists of the world getting together to basically laugh at how stupid Hubbard is:
"The Board heard evidence from a highly qualified radiologist who has made a special study of radiation and its effects. He said that Hubbard's knowledge of radiation, as displayed by his writings in All About Radiation, was the 'sort of knowledge that perhaps a boy who has read Intermediate Physics might, with a lot of misapprehensions and lack of understanding, demonstrate' ... "
We're pretty sure that, in the middle of a lot of extra words, they just said Hubbard knew less about physics than a confused child. That's about the strongest rebuke you can get from a community that tends to frown on words like "dumbass."
