How did you find PF?
My Physics professor recommended me to this site as a place to ask questions.
When I asked my professor "how do you find an answer for a question you don't know about Physics online" this is the site he recommended to me. Since most of my questions are about the theory more than the "homework" type, it's very hard to search for answers online.
