Bits and bobs....

• The hoary old story about legislating pi.
• Astro 106: support website for an introductory astronomy course at George Mason University.
• The Skeptic's Guide to Physics, Jess H. Brewer - an attractive set of pages supporting a `physics for poets' course.
• A very nice planisphere applet.
• ScienceNet - science questions and answers.
• `now for the science bit - concentrate!', a rather critical report about `public understanding of science' efforts, from a thinktank called River Path Associates.
• A&S II: The US National Institute of Standards and Technology, which published Abramowitz and Stegun, is working on a successor, the NIST Digital Library of Mathematical Functions.

Relativity and QM:

• Physics and relativity at Yahoo!.
• Relativity on the World Wide Web (original by Chris Hillman; maintained by John Baez).
• FAQs for Physics and Relativity
• The Speed of Light - a Limit of Principle? (an essay which magically goes from the rather elementary, to the advanced).
• General Relativity Tutorial (interesting, and avowedly not mathematical, but it's still follows the technical route through the stuff)
• Time travel in Flatland from Patricia at CalTech.
• Quantum measurement `FAQ'
• C-ship: Relativistic ray traced images: visualising relativity, from the wonderful wonderful fourmilab.

Time:

• Time standards at Yahoo.
• NPL's Time measurement pages.
• CNR (Italy)
• NTP homepage (Network Time Protocol) has various pointers to other stuff on this topic, including the text of RFC1305 which, as well as specifying NTPv3, has some interesting information on time standards in general.
• GPS overview
