I'm pleased to announce that Stack Exchange is now a major supporting partner of MathJax.
We love MathJax, and we use it on six sites in the Stack Exchange network so far with great success:
**[Quantitative Finance](http://quant.stackexchange.com/)** Q&A; for finance professionals and academics **[Electronics Design](http://electronics.stackexchange.com/)** Q&A; for electronic hardware hacking enthusiasts **[Statistical Analysis](http://stats.stackexchange.com/)** Q&A; for statisticians, data analysts, data miners and data visualization experts **[Physics](http://physics.stackexchange.com/)** Q&A; for active researchers, academics and students of physics **[Mathematics](http://math.stackexchange.com/)** Q&A; for people studying math at any level and professionals in related fields **[Theoretical Computer Science](http://cstheory.stackexchange.com/)** Q&A; for theoretical computer scientists and researchers in related fields
It turns out math is kind of ... important ... to a lot of the hard science communities. Who knew?
We were thrilled to be able to apply some of our VC unicorn dollars toward making MathJax a great open source tool for rendering math in web browsers -- not just on our communities, but across the whole of the internet. That's our fundamental mission: to make the internet better for everyone.
If you'd like to test out math notation on one of our sites, refer to a LaTeX2 mathematical notation reference and remember that
$$ are the delimiters that indicate when you enter and leave LaTeX2 mode.
Pause a few seconds for the real-time preview to kick in and see what kind of math you've wrought in your answer. Or, just view MathJax in action on the existing Q&A; at quant, electronics, stats, physics, cstheory, and of course math. Click the edit link (recently made available to all users) on any post to see the underlying markup.
Enjoy! We'll be working closely with the MathJax team to fold back in any feedback, enhancements, or improvements we come up with for the greater math community.
