I'm sure each of us has a huge list of unanswered questions. Here's a blog for archiving all such questions. It would potentially serve to get us and others some answers which have been eluding us for a long time. The answers can come in the form of comments. Please note that we should stick to questions we had honestly asked when we were in school, or pre-university college. We are strictly barred from trying to find answers to our research problems!
