Bamboozled

"One of the saddest lessons of history is this: If we’ve been bamboozled long enough, we tend to reject any evidence of the bamboozle. We’re no longer interested in finding out the truth. The bamboozle has captured us. It is simply too painful to acknowledge ~ even to ourselves ~ that we’ve been so credulous. So the old bamboozles tend to persist as the new bamboozles rise." Carl Sagan

Latex in Blogger

How do you insert equations like the following in Blogger?
\[ \vec{A}(\vec{r})=\frac{\mu_0}{4\pi}\oint_S\frac{\vec{J}(\vec{r'})\times\hat R}{R^2} d\tau'\]

First, you should know $\LaTeX$ typesetting. Second, you need to copy this script into your HTML template file.  

<script type="text/x-mathjax-config">
  MathJax.Hub.Config({tex2jax: {inlineMath: [['$','$'], ['\\(','\\)']],
                       displayMath: [['\\[','\\]'], ['$$','$$']]}});
  blogger.ui().viewType_.prototype.onRenderComplete=function(){MathJax.Hub.Queue(['Typeset',MathJax.Hub])};
</script>
<script type="text/javascript"
  src="http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML">
</script>

Here is how you do it. 


1. Go to your posts settings and choose Template from the left-hand bar

2. Click on the "Edit HML" button to edit your template

3. Click on the "Proceed button"

4. Scroll to the point right before the "<\head>" tag and paste the above script, then save your changes.

That's it! Now happy $\LaTeX$-ing.

Another $\LaTeX$ test

\[ \sin^2(x) + \cos^2(x) = 1\]

Just making sure that $\LaTeX$ is working on this site.

\[\mathbf{V}_1 \times \mathbf{V}_2 = \begin{vmatrix} \mathbf{i} & \mathbf{j} & \mathbf{k} \\ \frac{\partial X}{\partial u} & \frac{\partial Y}{\partial u} & 0 \\ \frac{\partial X}{\partial v} & \frac{\partial Y}{\partial v} & 0 \end{vmatrix} \]
