An excellent quick reference for lots of science stuff which was created and is constantly updated by Eric W. Weisstein.There is information on:

- astronomy
- biography
- books
- chemistry
- game of life
- mathematics (the math guide in book form is about 2000 pages long, and you can buy the book and/or CD)
- music
- physics

For those interested in such things, the raw information is in TeX, which is then converted to HTML for them web using LaTeX2HTML. Also, (at least the math section) has lots of internal links to other topics, much like Everything, which allows node surfing.
