Thanks, ropata. Euler’s formula deserves an article all on its own. I was quite stunned when I first encountered it. In this article I am speaking of the subtler beauty that comes with problem solving. I think most people can relate to it — we all enjoy solving puzzles of various kinds, and get a deep satisfaction from piecing things together. I would venture that your peers found school maths dry because, well, it is. Have they encountered mathematics as you and I know it?
