Earlier quoted context omitted.

Testing new HN version of script: [;A\boldsymbol{x}=\lambda\boldsymbol{x};] Seems to be working, in Chrome at least. Can some other people try it out? http://userscripts.org/scripts/show/112966 Put latex code inside square bracket semicolon pairs: [ ;...code...; ]

Works for me on Chrome 14. Testing: [;\frac{du}{dt};] [;\left[ \begin{array}{cc} 1 & 0 \\ 0 & 1 \end{array} \right];]

Now changed to use the MathJax default delimeters, as tzs explains.

It would be best to do this somewhere that supports MathJax ( http://www.mathjax.org/ ). HN does not, which could make it awkward to discuss math in an HN thread. There are three reasonable ways to add MathJax support to a site. 1. Get the site owner to do it. The site owner simply has to toss in a script tag that loads MathJax from the MathJax CDN and sets some configuration options. Someone would need to convince P…

Now updated and tested successfully in Chrome and Firefox (multiple versions of each) on Linux and Windows, with http or https.

Not working in Tampermonkey on Android (the script runs, but the notation doesn't happen).

Now using standard MathJax delimeters, \(...code...\) for inline or \[...code...\] for an equation.

I'd like to be involved (email in profile).

Are there significant differences between editions? For those not employed by Thomas, the 4th edition is a expensive book even when used. The 3rd, by contrast, has many affordable used copies available. And are the international versions identical?

Same thinking. $90 used is just too much, so I picked up the 3.ed. Hopefully it's good enough. Yes, please count me in too!
