Ok, I watched nearly all of the video.
I'm not a mathematician so I'm not sure how correct he is in most of his statements. Many of the more simple calculations exercises he asked the audience to do seemed to be correct but I'm not sure about the more complex statements he made.
There are 3 things in his presentation I found problematic:
1. He didn't come very prepared.
No power point or projector period. He holds up some big bulky pattern for a few minutes then goes to a trunk rambling through items that he gets but doesn't pass around or even mention much. This make him look a bit confused and unsure of what direction he's trying to take the presentation.
2. When asked direct questions that challenged his theories he seemed evasive trying to change the subject several times instead of giving definite answers. In one case he acted like he couldn't hear the question the young man presented to challenge one of his theories and kept asking him to talk into the microphone which looked like a bit suspicious. I've seen people do that before to evade questions.
3. Like Troy eluded to, when you talk about being able to cure AIDS and Cancer, those are serious claims that shouldn't be made lightly. It's cruel to give people false hope when it comes to things that cause so much suffering and death. Either you definitely can cure them or you can't.
His examples of currency and the mathematics involved in it were also problematic for me.
At first glance what he said about a dime and .10 times .10 of a pound and it's contradictions in applied math made sense, but upon 5 minutes of thinking about it...it didn't.
It looked like the White dude on stage and many of the White people in the audience were WINKING and SMILING at eachother as if they were "taking the piss" (as they say in England) at his expense. As if they brought him there for entertainment purposes in the first place.
But perhaps that may have just been the way I was reading their reactions.
