PlanetPhysics was a free, collaborative, online physics, mathematical physics, computational physics and physical mathematics project, including original articles, lectures, books and encyclopedia entries at http://planetphysics.us.
The original website is no longer available, but an archive from late 2011 has been restored here to continue the effort. It should be noted that the Talk pages contain the original restored PlanetPhysics content in TeX format. The TeX content was converted to Wikitext using a Latex2wiki.py script. Any discrepancies in content should refer to the original TeX for verification and authorship.
