Equations in Blogger (part 2)

  A while ago, I fumbled into a method to typeset equations on any web page. However, the JavaScript needed to do the work suddently disappeared (I didn't research that) and anyhow, the equations stopped displaying properly. 

Now I just found out that MathJax is available as CDN service. This makes my life way easier. You have to add a HTML/JavaScript gadget to Blogger and paste some code. The simple procedure is explained in their good documentation. 

So... want a taste of it? Let $\rho(\mathbb{x})$ be the probability density function of $n$ statistically independant variables distributed according to some distribution function. The normalization condition is:

\[ \int\cdots\int_{-\infty}^{\infty} \rho(\mathbb{x})d^n\mathbb{x} = 1. \]

Oh hell, I like this too much! Another one!

\[ \mathcal{H} = \frac{1}{2}\frac{p_{\theta}^2}{mL^2}-mgL\cos\theta.\]
