I'd like to see that particular video. I'd paid attention to what he actually said and wrote in other videos, and didn't catch any problem. Plus he is actually doing work for Indiana University, which is a pretty serious accomplishment. Plus he got published in Physical Review A. It is possible that we are both correct and that he learned enough between our observations.
I just realized you're probably asking about the relativity video, not the interview video. I searched for it on YouTube but can't seem to find it any more. It was a video of him talking about an error in standard presentations of the theory. I suspect he took the video down after learning more about relativity.
ETA: Found it. Most of what he says here just sounds like nonsense. The fact that the video is no longer on his own channel does suggest that he's come to realize this.
I'm friends with an incredibly smart kid. He's 14, but has been put up three grades in school at one point. He does all the obvious enrichment things which are available in the relatively small Australian city he lives in.
His life experience has been pretty unusual. He doesn't really know what it's like to be challenged in school. All his friends are way older than he is. (Once, I asked him how being constantly around people older than him made him feel. He replied, "Concerned for my future.")
He doesn't know anyone like him, which I think is a shame: he'd probably get along very well with them.
Does anyone know any similar kid geniuses? If so, can I give them my friend's details?
Thanks.
