A few months ago Professor Robert G. Brown of Duke University wrote at WUWT and elsewhere that members of Principia Scientific International (PSI) don’t know Mathematics (sic). Brown then defied PSI to prove that the inner core of a hollow metal sphere is not heated by “backradiation” ( a junk science concept alien to thermodynamics experts).
Then, as if to “prove” his claim that “backradiation” is “real” Brown wrote that if we wrapped a hot light bulb up with an aluminum foil, then in a very short time the bulb would be overheated. To Brown the ensuing overheating of the light bulb was by “backradiation” generated from the aluminum foil (applied scientists may be heard sniggering at the very idea!).
However, Brown was unable to show any actual relevant calculations (only a long and boring array of meaningless algebraic gymnastics) to support what he said. Nonetheless, I took very seriously his challenge and I tried to calculate, in the most precise way, what really happens whenever you wrap a light bulb up with an aluminum foil.
What I present herein are typical, sound and established equations that any serious applied physicists, engineers, technicians, etc., will often use in the course of their work in what is euphemistically known as the “real world”. This is perhaps why academics like Brown, residing in their (“unreal world”) ivory towers, so often fail? For instance, it is a routine task for applied scientists and engineers to, say, calculate how much an electric wire may heat surrounding plastic insulation cable, or define the temperature reached by the casing of car engines in close contact with pistons, etc.
Clearly, it comes as a surprise for Mr. Brown (but not for PSI!) that in the fields of applied science it is impossible to find ANY manuals, technical textbooks, etc., using climate science’s mysterious “backradiation” to carry out such practical (“real world”) calculations.
“Backradiation” is regarded as a sort of “Arabian Phoenix” in the scientific and technical community. Of course, the academics and global warming believers are saying it exists, but nobody has ever actually found it! Maybe Professor Brown believes otherwise, but I have never met an engineer devising an engine, an industrial plant, or an electric device using “backradiation” to calculate how much heat is passing through the materials!
