So [far](numericq.html), I relied on the capability of [zim](notes-and-more.html) to convert a LaTeX expression to an image when I wanted to insert an equation into a blog entry. I never really liked that, but it at least worked. [MathJax](http://www.mathjax.org/), the successor of jsMath, has now reached a maturity that it has become a viable alternative. More than that: MathJax allows the use of native LaTeX code directly in the HTML source, and its rendering is perfectly [scalable](http://www.mathjax.org/demos/scaling-math/). I've set the following example (compare to my [previous](numericq.html) entry) to a size of 125% and a zoom active on a left click. Note that you need to allow Javascript on this page to actually see the rendered equation. Right-click to obtain the source. \\[\\begin\{aligned\} U(B) = S \\int\_0^\\infty dt \\exp(-\\Delta x^2/4 D t) \\exp(-t/\\tau) \\cos(g \\mu\_B B t/\\hbar)/ \\sqrt\{4 \\pi D t\} \\end\{aligned\} \\]
