A sad sight: so much effort and background research went into this paper, and yet so superficial is the author's understanding of QED and renormalization.

In another discussion on HN today Feynman's little book "QED" came up. It is still a great read and I think it conveys the theory's elegance very well. So I would suggest to read it instead of this article.

Unfortunately I do not know any good books explaining renormalization to the general public. Maybe someone else has an idea?
