No, this isn't about Rebecca Watson. This is about a mathematics, err 'mathematics', cough 'book' I was introduced to today by the sheerest of accidents. I 'found' a new blog I hadn't before heard of, and I was reading a rather detailed discussion on category theory (absolutely interesting subject one notes). So, there are some mathematically bright people there, which is probably why I enjoyed the discussion.
The host of the place goes by the name MarkCC, and I must say that in my first few minutes of reading over there I am suitably impressed to have included his blog in my google reader doohickey.
However, his about page has a link on it left by a commenter. This link is um, special. Yeah, it's special. That's it. Mm hmm. It's to an online book which seeks to properly determine the value of pi. It is, I am assured, not ~3.14. No, it's 3.125. Oh here, take a look for yourself.
