Over the years I've accumulated many pages of mathematical notes, problems, solutions, computer programs, calculator functions, etc. As time permits (and time is not so permitting lately) I will work to post more pages so that they may be more useful to someone than they would be stashed away in a drawer somewhere.

Just about anyone who knows me would be able to tell you that I have a 'thing' for

Probably my most important mathematical discovery to date is that of a Ramanujan-like series formula for 1/π

This formula has since appeared in several publications, among them: Tito Piezas'

I've been questioned several times over the years regarding the possible existence of other formulas of this type, involving even higher reciprocal powers of
