I just wanted to say: the video in the OP is mine. Yes, the calculations are very "back of envelope" and I deliberately erred on the side of overstating the numbers at each stage. Space and radiation are not my specialist subject but I can figure out basic energy calculations!
I thought it was a fantastic rebuttal, and as you acknowledge it was a 'back of an envelope calculation.' You even deliberately understated or overstated numbers that were not in your favour. The compromises you made with the numbers were one of the rebuttal's redeeming features as it clearly showed you were not trying to hide or fiddle the numbers at all.
There is a long history of trying to lead Jarrah through the physics and math of the radiation problem. Several people have tried to take him a little further than 'it's a sea of killer radiation' and lead him to the idea of particle energy distributions, fluxes and attenuation. He cannot grasp this simple idea.
The
IMDb debate is worth a read if you have time. This debate was centered on the solar radiation problem which is much more complex than the van Allen belts, but if you take a read Jarrah could not get past first base and the idea of integrated fluxes.
I was going to compile a critique of Jarrah's radiation series about 4 years ago, but I neither had the time nor the inclination to be bothered with him in the end. He's simply not prepared to learn if it means a challenge to his arguments. I'm afraid too much time has been invested in the hoax, and he's now the young (and obsessed) pretender that has taken on the crown of Kaysing and Rene. His ego will not allow him to surrender that crown. You could take him by the hand to each of the landing sites, and he'd still find a reason to deny their existence.
I seriously would not waste your time with the guy, I've been there and done that. I'm UK based, and his anger issues led to police involvement when he doc-dropped someone else in a video believing them to be me. Not bad considering he lives in Sydney.
I quickly realised that I would learn more about Apollo and the science if I spent less time urinating into the wind with the Blunder. The Apollo legacy lives on, and it has given me an incredible amount of joy. I now visit schools once a month as a volunteer, talk about Apollo and get the kids making stomp rockets. They love watching videos of the launches and astronauts on the moon.
I've learned so much about moon rocks and how they have informed the evolution of our planet, the science of retro-reflectors and how they have informed General Relativity, I have a deeper knowledge of solar physics. I have learned about the history of Apollo, the engineering of Apollo, the people that made Apollo possible, I have taken up photography, I have learned about the space programs before Apollo and the politics of the time. Apollo has renewed my interest in other areas of science too. I seriously would not waste too much time with the YouTube hoax crowd. They are a special bunch.
Well done on the video, it was good work.
