The articles listed below represent my own attempts to get to grips with some of the mathematical topics which have interested me. I do not claim any originality (or indeed, veracity) for the discoveries and proofs which they contain but they are the results of my own investigations, not mere copies of Wikipedia articles. I have, however, used Wikipedia and other excellent maths sites to check what I have written.
