What I find interesting about this video is the claim that he "is not a scientist" - I beg to differ. I do not know his formal education background, but that should not diminish his ability to apply the scientific method which he has clearly shown. After all, he is an expert in the field of moving large objects, if there is such a field.
From wiki: "A scientist, in the broadest sense, refers to any person that engages in a systematic activity to acquire knowledge or an individual that engages in such practices and traditions that are linked to schools of thought or philosophy."
From the video, it's quite apparent that he applies a systematic activity to achieve his goal, that being knowledge in our case, and it's linked to a school of thought - construction, and not to mention mathematics and physics (it's obvious there's math involved here whether he knows it or not) for the application of the scientific method.
Thus, without formal education, I feel his demonstrations clearly prove he a scientist in the broadest sense- I'd welcome opinions for or to the contrary if you're interested.
