"This document (a simple ASCII file) contains answers to some more or less frequently asked questions from theoretical physics. Currently, the FAQ contains 148 topics, grouped into 20 chapters, and filling over 10000 lines of text (about half a megabyte), corresponding to a book of about 200 pages. Starting in 2004, the topics were edited from my answers to postings to the moderated newsgroup sci.physics.research (or, for some, translated from postings to the unmoderated German newsgroup de.sci.physik).
