    I have enabled MathJax on the site. There are no Latex images being displayed. Please post any problems. I'll leave it enabled for the next hour or so and switch back to images until we are 100% ready.

    So I wrote the LaTex code for y=x^2 and a dubious thing appeared (below). Do these essentially replace the nicely looking LaTex images and to make them we'd still have to type the LaTex code ?

    [tex] y=x^2 [/tex]

    Nothing in what you do changes :)

    So, Greg, it's the image which changes and the lower space on the server occupied by the tinier pictures, right ?

    The align environments seem buggy, plus some markup in my blog posts don't render. I'm trying to troubleshoot now.

    The blog needs to be reworked, there were a few extra things we needed to do to make latex work on the blogs and I haven't touched that yet, so disregard the blogs for the moment.

    Testing, testing...

    [tex]-\frac{\hbar^2}{2m}\nabla^2 \Psi + V \Psi = i \hbar \frac{\partial \Psi}{\partial t}[/tex]

    Test of align*:
    [tex]
    \begin{align*}
    \nabla \cdot \mathbf{E} &= \frac{\rho}{\varepsilon_0} \\
    \nabla \cdot \mathbf{B} &= 0 \\
    \nabla \times \mathbf{E} &= -\frac{\partial \mathbf{B}}{\partial t} \\
    \nabla \times \mathbf{B} &= \mu_0\mathbf{j} + \mu_0\varepsilon_0 \frac{\partial \mathbf{E}}{\partial t}
    \end{align*}
    [/tex]

    I have four ([itex]4[/itex]) in this line of text. I "accidentally" typed ([itex]3[/itex]) the first time but saw it in preview, changed it, and the preview worked properly!

    Can I draw a commutative diagram?
    [tex]
    \begin{CD}
    A @>>> B \\
    @VVV @VVV \\
    C @>>> D
    \end{CD}
    [/tex]
    Nope (didn't expect this environment to work anyways). But interestingly, I get a box containing the latex code. Hrm, how about as a matrix?
    [tex]
    \left[
    \begin{matrix}
    A &\to& B \\
    \downarrow & & \downarrow \\
    C &\to& D
    \end{matrix}
    \right]
    [/tex]
    Successful!

    Ooh, quick edit doesn't play nicely.

    I just quick edited this post to put "[itex]\sqrt{3}[/itex]" in the post, but the latex didn't render and I just saw the raw text. But if I reload the page, it will look right.

    edit: Or, eI thought reloading would. Nothing's rendering now. :(

    edit2: Ah, now reload's working.

    Greg, the align* environment should align the LaTeX by placement of &s.

    Sometimes I see it rendered correctly, other times not. See attached image.

    Why the sudden change?

    Sorry to say I really hate the new look. The images are smaller, and arew just ugly compared to the old font. Please bring back imgtex =)

    Greg, during the test was the math rendered with cmr font? (Didn't look like it, but hard to tell...)
