I like the article. I find myself doing math problems all the time just for fun, I am glad that I am not the only one. Of course, I have not solved anything that would ever win me a Nobel prize. But I had fun. One day my 9 year old son and I derived Pi with approximations and a calculator, and my kid likes calculating geometry now. Better than watching TV all day.
