I bet you were all wondering how I got all those pretty ∂s and Δs in all my posts last week on my physics problems (Part of me wants to delete them, part of me wants to clean them up, most of me wants to deny their existense). I want to emphasize this to make my life easier when giving help in the smartsite chat rooms. It allows html, use it!
And the answer: This wonderful table of html codes. I'm almost to the point where I'm going to print it out and frame it on my wall or something. A part of me died every time I tried to understand people's N_A/K_A+Y. I'm still torn on the fraction slash. It doesn't seem to be rendering consistently well.
