The Physics Travel Guide is an expository wiki which explains concepts in three levels of difficulty. We call these levels: intuitive, concrete and abstract.
Try it. What do you want to understand?
It's an expository physics wiki, but also much more than that:
There already exist great explanations for almost any topic. However, currently, they are often incredibly hard to find and hidden in old textbooks or in papers buried somewhere on the arXiv. Our goal is that great explanations get the attention they deserve.
In contrast to, for example, Wikipedia we do not simply refer the readers to the most rigorous textbook and the original paper, i.e. the "standard references". Instead, we want to collect those resources that are the most helpful for students. We want to help learners to discover the best resources for each stage during their journey.
The Physics Travel Guide tries to fill a gap because textbooks and lectures usually don't acknowledge that there is a difference between pedagogy and andragogy. Textbooks and lectures explain things linearly and try to be pedagogical. "Pedagogy" is a synthesis of the two Greek words "paidos" (child) and "ágō" (to lead) and literally means "to lead a child". In contrast, "andragogy" means literally "to lead a man" and is the study of methods and principles to teach adults. It's clear that you can't teach children and adults in the same way.
This Physics Travel Guide has the needs of adults in mind, is non-linear and ideally suited for self-directed learning.
The following pages give an idea how this works in practice:
The Physics Travel Guide exists to lower the entry barrier to technical topics for laymen, students and researchers alike. Specifically, it's a tool for:

The Physics Travel Guide is currently not complete and never will be. However, everyone can help to make the current gaps smaller.
