Of course, once he comprehended the context (not content) of his shellacking, he accused you of asking an impossible question...
Of course, "impossible" because he couldn't figure out how to answer it.
(a) Why did it take him so long to go back and come back with his objection? (answer - because he couldn't find the answer using Google.)
(b) He would find the answer on Google if he had the knowledge (I did).
That's part of my debate philosophy. When a proponent presents an argument that embodies a pretense to expertise, I ask questions that require knowledge, not facts. You can Google for facts, but you can't Google for knowledge. You either have it or you don't, and the only way to get it is to do real work in the field and make mistakes in it. If you don't have the appropriate knowledge, then you don't get to say that everyone in the profession is wrong and you're right. Jarrah can whine all he wants that I'm being unfair, or that his teacher didn't catch his mistakes, or that we should excuse any other situation in which his incompetence has been revealed. But my ears are deaf to that; he's taking on the fields of astrophysics and aerospace and calling them liars, and he can expect no quarter.
(c) How can he prove proton correlation if there is no data pre-1976 (he cannot have his cake and eat it)?
(d) Does he actually realise that proton data exist pre-1976, so why is he asking you that question?
(e) Does he actually know that one does not need a satellite to obtain proton data?
As with most conspiracy theorists who attempt the science, he applies only a cargo-cult level of reasoning toward these measurements and their understanding throughout history. For heaven's sake, we have solar emission data from the Victorian era. His inability to determine how such things were known prior to the modern satellite measurements is simply an example of that cargo-cult mentality. At some point people who deploy that kind of argument have to realize how feeble it will be in the real world. I interpret Jarrah's unwillingness to defend his findings to qualified experts as his admission to that realization.
(f) When he tried an integrated dose calculation he still did not understand the concept of calculus.
And that's why it's laughable for him to claim to be studying astrophysics. It's one thing to botch a calculus computation for some trivial reason. It's another thing altogether to be unable to display any understanding whatsoever of what calculus is and why it's necessary to a correct understanding of the properties of the physical world. Someone who is entirely oblivious to the
concept of calculus will have no success whatsoever in the study of most physical sciences beyond the high school level.
