I wanted to give a quick shout out to a resource that through out my physics career has been extremely valuable. That resource is list serves. There are two that are my favorites:
1. Tap-L: A list serve for teachers, profs, and lab techs. If you have an apparatus question or opinion these folks have answers.
2. Phys-L: A list serve for content, pedagogy, and general physics questions. It is a great resource if you are struggling to teach, or understand a specific topic.
A link to find out more information on how to join these lists, or learn a little more about them is below:
