I'm gradually adding links to this site. Although a couple of the links are to political sites, my intention is to focus on sites that are useful references. The Merriam-Webster site, for example, is a dictionary with an audio feature that finally taught me how to pronounce lese-majeste. The Nature and Physical Review Focus sites are the best I've found for quick news about serious science. Suggestions for additional links are hereby solicited.
On an adjoining front, I'm working on my list of the best single volume references to various fields for people who are either serious about understanding things or too vain to give up trying—probably a distinction without a difference. I've got candidates for chemistry, physics, statistics, and set theory.
