  • Physics.Stackexchange - The largest question and answer physics community.
  • PhysicsOverflow - An alternative to Physics.Stackexchange, which was started by a group of users unhappy with the restrictive moderation.
  • Physics Forums - The largest physics forum.
  • Quora Physics - Another question and answer community, which is especially good for meta questions and opinion questions, which are not allowed at Stackexchange.
  • /r/Physics/ - The physics subreddits mostly focuses on discussions of recent news.
  • CosmoCoffee - Another nice physics forum with a focus on cosmology.
  • sci.physics - The oldest physics community, which is however no longer very active. However many great discussions can be found in the archives.

It's also crucial to ask people questions and explain things to people — both of these are great ways to learn stuff. Nothing beats sitting in a cafe with a friend, notebooks open, and working together on a regular basis. Two minds are more than twice as good as one! But if you can't find a friend in your town, there are different ways to talk to people online. In all cases, it's good to spend some time quietly getting to know the local customs before plunging in and talking. For example, trying to start a rambling discussion on a question-and-answer website is no good. Here are some options: Question-and-Answer Websites — If you've got physics questions, try Physics Stack Exchange. For research-level questions, try Physics Overflow. For questions about math, try Math Stack Exchange, or for research-level questions, Math Overflow. Discussion Forums — To get into discussions of physics, try sci.physics.research. For math, try sci.math or, for research-level questions, sci.math.research. I also recommend Physics Forums for both math and physics discussions. At least some of the question-and-answer websites listed above also have community forums where you can discuss things. John Baez

Big Questions for SOLE Searchers


No book is perfect and therefore it is inevitable that readers get stuck somewhere. That's why it's often incredibly helpful to read the thing the authors wants to express formulated in different terms. Sometimes such alternative formulations exist in the form of reading notes, which are notes that someone took while reading the book. Here we collect such notes and in addition, solutions for textbook problems and answers to frequently asked questions.


While a main idea of this travel guide is that physics is best learned in a self-directed manner, a little guidance is never harmful. Especially, because it happens often that beginner students get lost and can't see the forest for the trees.

For this reason, we collect here roadmaps. These are rough guides that explain which topics and resources are essential to understand a given topic and outline possible ways to tackle to subject.

There is no perfect roadmap that is a good fit for everyone. Therefore it's crucial that everyone finds a roadmap which matches his/her style.

General Roadmaps

In addition, to these general roadmaps there are also more specific roadmaps. These are listed on the overview page for the corresponding subject, e.g. on the following pages

LaTeX Tips

  • Learn by looking at .tex documents created by more experienced people. For almost any paper uploaded to the arXiv you can download the corresponding .tex file. To do this, go the abstract page, then click on "Other Formats" in the menu on the right-hand side, then on "Download source".
  • Use Detexify to look up LaTeX symbols
  • Define shorter commands for often used commands. To do this add lines like the following before \begin{document}
  • To structure your TeX code better, make use of #. For example, to get a empty line without creating a indentation in the formatted document after an equation:
