Walter Tautz: As a headsup, for the \\(\TeX\\) content that John uses in his posts they're *slightly* different from standard due to the changes needed for this forum (to keep mathjax and markdown compatible).

If you go to the [gitbook repository](github.com/rabuf/applied-category-theory) that we've got going you'll find most of the changes already done for you (mostly getting rid of extra backslashes). The only other change you might want will be to replace every instance of `\(` and `\)` in the markdown files in the repository with `$$` or `$`.
