Twenty Twelve WordPress theme
I switched to using the Twenty Twelve WordPress theme a few days ago. I really am liking it although I’m not sure about the header image being below Site Title and Tag Line. That looks a little strange to me.
Having said that, I think Twenty Twelve looks fantastic on the demo site.
Currently you have get Twenty Twelve from the WordPress trac repository as as far as I know it is not released yet. They will release it as a stand alone theme soon I believe, so you can try it out before WordPress 3.5 is released.
I did agit cloneof the WordPress code mirror on github, into my home directory. Then I symlinked the~/wordpress-git/wp-content/themes/twentytwelvedirectory to my live WordPress install path. That way I can simply do agit pullto update the theme. -
\(\LaTeX\) Equations in WordPress using MathJax
I came accross this great tool for displaying mathematical equations the other day. MathJax not only supports \(\LaTeX\) syntax but also renders the equations as pure text, so no unsightly images and they scale beautifully. You can also right click on the equation and see it’s \(\LaTeX\) code.
The code for MathJax is open source, but if you don’t want to go to the bother of installing it yourself, you can use it on their CDN.
There are a couple of plugins to enable MathJax in WordPress. I’m using the Simple MathJax plugin. I’ve not tried the others.
To use MathJax simply mark up your equation with\[…\]. If you want to have an equation inline, use\(…\). You can also inline equations in the post title.
Here are a few examples taken from the MathJax site:The Lorenz Equations
\begin{aligned}
\dot{x} & = \sigma(y-x) \\
\dot{y} & = \rho x – y – xz \\
\dot{z} & = -\beta z + xy
\end{aligned}The Cauchy-Schwarz Inequality
\[\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)\]
A Cross Product Formula
\[\mathbf{V}_1 \times \mathbf{V}_2 = \begin{vmatrix}
\mathbf{i} & \mathbf{j} & \mathbf{k} \\
\frac{\partial X}{\partial u} & \frac{\partial Y}{\partial u} & 0 \\
\frac{\partial X}{\partial v} & \frac{\partial Y}{\partial v} & 0
\end{vmatrix}\]The probability of getting \(k\) heads when flipping \(n\) coins is
\[P(E) = {n \choose k} p^k (1-p)^{ n-k}\]
An Identity of Ramanujan
\[\frac{1}{\Bigl(\sqrt{\phi \sqrt{5}}-\phi\Bigr) e^{\frac25 \pi}} =
1+\frac{e^{-2\pi}} {1+\frac{e^{-4\pi}} {1+\frac{e^{-6\pi}}
{1+\frac{e^{-8\pi}} {1+\ldots} } } }\]A Rogers-Ramanujan Identity
\[1 + \frac{q^2}{(1-q)}+\frac{q^6}{(1-q)(1-q^2)}+\cdots =
\prod_{j=0}^{\infty}\frac{1}{(1-q^{5j+2})(1-q^{5j+3})},
\quad\quad \text{for $|q|<1$}.\]Maxwell’s Equations
\begin{aligned}
\nabla \times \vec{\mathbf{B}} -\, \frac1c\, \frac{\partial\vec{\mathbf{E}}}{\partial t} & = \frac{4\pi}{c}\vec{\mathbf{j}} \\ \nabla \cdot \vec{\mathbf{E}} & = 4 \pi \rho \\
\nabla \times \vec{\mathbf{E}}\, +\, \frac1c\, \frac{\partial\vec{\mathbf{B}}}{\partial t} & = \vec{\mathbf{0}} \\
\nabla \cdot \vec{\mathbf{B}} & = 0 \end{aligned} -
