__Renormalization: Our Greatly Misunderstood Friend__

### Abstract:

This is a web-paper write-up for a talk I gave for Intermediate Seminar
at Johns Hopkins Unversity (172.711-712). I will present a friendly, although
slightly technical introduction to the theory of renormalization. Examples
from nonrelativistic quantum mechanics and quantum electrodynamics will serve
to introduce the concepts. The ``Algorithm of Renormalization'' will then
be presented and explored. Finally, I will present an overview of Wilson's
Renormalization Group, and show how we can make the ideas in this paper
surprisingly quantitative.

*The Intermediate
Seminar at Johns Hopkins University's
Physics and Astronomy Deptartment is a year long seminar taken by all
second-year graduate students. The requirements change on a yearly
basis, but my requirements included a twenty minute talk and a fourty-five
minute talk. The first talk I am publising here as a web article.
The second talk can be found as a paper here. As
this seminar is for graduate students in physics and astronomy, there are
some technical details in these papers, and some of the talk is quite formal.
I will do my best here to be as clear as possible to the general public,
although I'm assuming you know a little quanum mechanics.*
