Hmm, what a shame that the LaTeX content wasn't properly rendered in the linked article. When I noticed this I assumed someone had forgotten to include the MathJax JavaScript library, which, when present, converts LaTeX notation into properly rendered LaTeX client-side.
As it turns out, the MathJax library is called from the article's HTML (in line 1765), but for some reason it's not working.
A long-running debate argues that LaTeX rendering should be a default browser feature, so far without success. In the meantime MathJax works pretty well unless someone disables JavaScript client-side.
Reasonable people may differ, but not being able to render LaTeX is egregious and wrong.
