So let's say you are a geek/nerd in the Math/Physics sense. You have been constantly wondering why not everyone uses LaTeX to write everything. Sadly, when you hit the web you are even more distressed because the last thing you want to do is old school ASCII art. Well thanks to MathJax your sites can look like $$\begin{aligned} \nabla \times \vec{\mathbf{B}} -\, \frac1c\, \frac{\partial\vec{\mathbf{E}}}{\partial t} & = \frac{4\pi}{c}\vec{\mathbf{j}} \\ \nabla \cdot \vec{\mathbf{E}} & = 4 \pi \rho \\ \nabla \times \vec{\mathbf{E}}\, +\, \frac1c\, \frac{\partial\vec{\mathbf{B}}}{\partial t} & = \vec{\mathbf{0}} \\ \nabla \cdot \vec{\mathbf{B}} & = 0 \end{aligned}$$

So to get this going was actually straight-forward

• Add MathJax to your site using javascript libraries as the external URL use http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML
• place the library in the header region
• create a text formatter (MathHTML) that does nothing
• write your equation-fu using something like

   <script type="math/tex; mode=display">
  \begin{aligned}
  \nabla \times \vec{\mathbf{B}} -\, \frac1c\, \frac{\partial\vec{\mathbf{E}}}{\partial t} & = \frac{4\pi}{c}\vec{\mathbf{j}} \\
   \nabla \cdot \vec{\mathbf{E}} & = 4 \pi \rho \\
  \nabla \times \vec{\mathbf{E}}\, +\, \frac1c\, \frac{\partial\vec{\mathbf{B}}}{\partial t} & = \vec{\mathbf{0}} \\
  \nabla \cdot \vec{\mathbf{B}} & = 0
   \end{aligned}
  </script>
  

  
  The math/tex sets TeX mode, mode = display means a TeX display equation vs. leaving out mode=display and getting an inline equation
