AN EXPERIMENT that for eighty years has been cited by physicists as a confirmation of Einstein’s special theory of relativity is nothing of the sort. This remarkable discovery has been made not by a professional physicist but by an enthusiastic amateur.

I do not make any clear distinction between mind and God. God is what mind becomes when it has passed beyond the scale of our comprehension.

The papers I looked are highly technical so it's entirely possible I am wrong. More sleuthing produced this.

The most recent publication I could find is one from this year: https://books.google.com/books?id=UfetDgAAQBAJ&pg=PA247 The author's point is that there's no adequate theory for even simple electromagnetic phenomena within material that is accelerating. The amateur, Pellegrini, had questioned the assumption that they could be treated by ignoring the acceleration. At any rate, it seems he had a point, if more than 20 years later there's no scientific consensus about the question.

I’m not sure Pellegrini isn’t an expert even though he isn’t a professional physicist. If I read the article correctly it looks like he has spent many years thinking about the subject. A person can be an expert in some subjects without formal qualifications don’t you think? Did I miss something? He certainly not a professional physicist as I read it but I am not sure that makes him a lay person either in practical terms (although I guess technically it does). |
