Rather than providing yet another Welcome to the Internet
webpage with superfluous links to Google, here are some online
resources that I find potentially useful and at least somewhat
obscure. I will update the list as I remember/encounter new
resources.
Software
- Tachikawa's very useful spires (unfortunately, only available for OS X)
- SPIRES browser plugins and other goodies
- PidginTeX
- MathIM
- Headrick has a number of useful Mathematica packages.
- Michelson also has some Mathematica packages, some of which may be out of date.
- Cadabra
- xAct, a set of Mathematica packages for tensor manipulation.
Free Textbooks, Notes, and References
- Cain has posted an extensive list of free online math textbooks.
- AMS has a directory of online books.
- Georgi has several textbooks and notes available, including The Physics of Waves and Weak Interactions (a newer version is available as a book).
- Siegel has his Fields textbook, along with several other useful resources.
- Carroll's Lecture Notes on General Relativity (a newer version is available as a book).
- An early draft of Srednicki's Quantum Field Theory textbook is available here.
- Abromowitz and Stegun's Handbook of Mathematical Functions.
- A slightly outdated string theory literature review; many of the items are available online.
- The Particle Data Group puts out free particle physics data and reviews.
- Cahn shares an electronic copy of his book, Semi-Simple Lie Algebras and their Representations.
