Ultimate explanation of renormalizations

Trying to communicate my results and ideas to people, I started to prepare a PowerPoint document. Any theoretical physics student can follow it. An article version is here: http://arxiv.org/abs/1110.3702.

There are so many different “expoundings” of renormalizations in the literature. I think mine is the only correct one. The others mislead and even fool you. For example, one geek considers the Archimedes effect as a mass renormalization and says that it may give a negative effective mass. What a shit! Don’t buy it! Whatever is the resulting force applied to a body \vec{F}_{tot} = \vec{F}_1 + \vec{F}_2 + \vec{F}_3+..., the body mass remains the same. 😉

P.S. I am speaking, of course, of the “old-fashion” problem of coupling certain equations, not of the solid-state-like renormalization à la Wilson. In other words, I do not touch the effective theory approach, which works fine where it belongs.
