I've started an expository physics wiki that collects great explanations. It's called the “Physics Travel Guide” and available at https://physicstravelguide.com. The idea is to - curate the best explanations for various levels of understanding (laymen, students, researchers). - be a platform where people can publish new explanations and to help students discover them. - offer roadmaps for people who want to learn some topic but don't know how. The Physics Travel Guide is currently not complete and never will be. However, everyone can help to make the current gaps smaller. So, for example: - If you've published a great explanation elsewhere, you can simply add a link to it such that others can find it more easily. - You could add links and references to your favorite textbooks, papers, blog posts etc. - You could publish an explanation that you'd always wanted to share with others. - You could edit and improve existing explanations. Long story short: I would really appreciate it if you'd check out https://physicstravelguide.com and maybe consider contributing something to it. Of course, please let me know if you have any questions or ideas.
