Maybe I am out of the loop and missed something, but I did not get a "this guy thinks he is superior to us" vibe from his post (and I am usually the first to notice such slights).

I really like his post and he has piqued my interest in learning more about da Vinci, of whom I knew very little.

Your post seems a bit harsh. Not everyone here is well-educated in the same fields. I am not even a high-school graduate.
