I am a chemist who dabbles in programming. My current obsession is Excel VBA. I am a total newbie to programming anything other than basic HTML. I am very good with Excel, but programming? Not so much. I don't even know enough to explain my problems well! As for chemistry, I have a PhD in analytical chemistry. And I wish to use this knowledge to teach others. What I'm doing in excel has everything to do with my post-doctoral work, and hence I can't include much of my code.
