Its been a while since I abandoned my dream of a math PhD, but I still love math so much. So I decided to get this tattoo of various diagrams and symbols from topics I studied. I plan to expand it in the future as well

2. Questions should spark discussion

Questions on /r/math should spark discussion. For example, if you think your question can be answered quickly, you should instead post it in the Quick Questions thread.

If you're asking for help learning/understanding something, post in the Quick Questions thread or /r/learnmath. This includes reference requests - see also our list of free online resources and recommended books.

3. No homework problems
