  Now I see that it seems to be required to activate JavaScript
  in the browser as the source code of the HTML web page is:

|<p><script type="text/x-mathjax-config"> 
|  MathJax.Hub.Config({ 
|    extensions: ["tex2jax.js"], 
|    jax: ["input/TeX","output/HTML-css"], 
|    tex2jax: {inlineMath: [["$","$"],["\\(","\\)"]]} 
|  }); 
|</script> 
|<script type="text/javascript" src="/mathjax/MathJax.js"></script> 
|
|Here's something that caused me undue confusion over the
|years as I was learning about tensors.</p>
|
|<p>Many textbooks, for instance, will tell you that the
|metric tensor of special relativity takes a form like</p>
|
|<p>\[
|\eta_{\mu\nu}=\begin{pmatrix}-1&0&0&0\\0&1&0 . . .
|\]</p>

  . Still, it would be interesting if anyone could comment
  on what "dialect" of TeX/LaTeX is used there and how one
  could format it using an implementation of TeX or LaTeX!
