"\\" do not render a newline.

$$ a \\ b $$ should render

a
b

But I only get

a b

in my blog.
And this is my test page http://www.jiang.jp/blog/test/ .
I use python-markdown to convert the code to html. Dose this the reason "\\" do not work?
I know this issue maybe not related to mathjax but I have googled for near 1 hour and didn't find anyone who had the same problem.

Markdown uses the backslash (\) as an escape character to prevent a special character from having its usual meaning, and \\ means include a literal \. This means your \\ is being turned into a \ by markdown, so the HTML page that MathJax processes only has a single \, not a double one, and that does not produce a new line.

You will need to double all the backslashes (so use \\\\ rather than \\), and will probably have to use \_ instead of _, if your flavor of Markdown uses _ to indicate italics.

See the MathJax documentation for more details about using MathJax in HTML and Markdown documents.
