The laws list originally started out strictly as a list of laws. Then, because of their similarity, I began adding rules to the list (after all, in physics, there is generally no difference between a law and a rule). Over time I added more and more similar subjects. Now, the list is more of a minidictionary of physics and astronomy terms, rather than strictly a list of laws, rules, and so forth; however, for historical reasons I still refer to it as the laws list, even though it is something of a misnomer.
