Why you should contribute
If you read this wiki you should contribute. Basically, we need readers to make contributions for this wiki to really work. No matter how little you know about the mathematical theory you will find typos and small errors on pages as you read them. If you start to work through the matheamatics you will find errors in the equations, gaps in the derivations or points which confuse you and where you really had to think to make progress.
If you make a contribution to fix these typos, add in extra information, or make requests you will be contributing in a very meaningful way.
Finally, we notice every edit and it makes us feel great that you have gone to all this trouble.
