First edition, journal issue in original printed wrappers - "Invention and exploration of the renormalization group" (IHEP's Chronology of Milestone Events in Particle Physics). "This paper is one of the most important ever published in quantum field theory. To give you objective ev…idence of how much this paper has been read, I may mention that I went to the library to look at it again the other day to check whether something was in it and the pages fell out of the journal. And it is one of the very few papers for which I know the literature citation by heart. (And all the others are by me.). This paper has a strange quality. It gives conclusions which are enormously powerful; it's really quite surprising when you read it that anyone could reach such conclusions. The input seems incommensurate with the output. The paper seems to violate what one might call the First Law of Progress in Theoretical Physics, the Conservation of Information" (Steven Weinberg, 'Why the renormalization group is a good thing', in Asymptotic Realms of Physics, Essays in Honor of Francis E. Low. Edited by Alan H. Guth, Kerson Huang, and Robert L. Jaffe. Cambridge, MA: The MIT Press, 1983). The "renormalization group refers to a formal apparatus that allows systematic investigation of the changes of a physical system as viewed at different scales. In particle physics, it reflects the changes in the underlying force laws (codified in a quantum field theory) as the energy scale at which physical processes occur varies . . . As the scale varies, it is as if one is changing the magnifying power of a notional microscope viewing the system. In so-called renormalizable theories, the system at one scale will generally be seen to consist of self-similar copies of itself when viewed at a smaller scale, with different parameters describing the components of the system. The components, or fundamental variables, may relate to atoms, elementary particles, atomic spins, etc. The parameters of the theory typically describe the interactions of the components. These may be variable couplings which measure the strength of various forces, or mass parameters themselves. The components themselves may appear to be composed of more of the self-same components as one goes to shorter distances. For example, in QED an electron appears to be composed of electrons, positrons (anti-electrons) and photons, as one views it at higher resolution, at very short distances. The electron at such short distances has a slightly different electric charge than does the dressed electron seen at large distances, and this change, or 'running', in the value of the electric charge is determined by the renormalization group equation" (Wikipedia).
