Temporary Move


While commenting issues are being resolved at our old premises, we have moved here.

To add comment in latex, write

dollar sign latex your stuff dollar sign.

So dollar sign latex e^{-\frac{(x – \mu)^2}{2 \sigma^2}} dollar sign yields

e^{-\frac{(x - \mu)^2}{2 \sigma^2}}.

    Let’s see if latex works.

    \sum_{i = 0}^{\infty} i^i

    Ouph… Where is RSS feed? Will you set it up?

  3. math_reader Says:

    Hope the original location goes back to normal soon… If you wish to make over here look a bit more over there, you might want to add the same familiar header image (and remove the text title), see this http://en.support.wordpress.com/themes/custom-header-image/

    a = b

  5. tomleinster Says:

    Testing: e^{\pi i} \dashv \prod_{i = 1}^n \to X

  6. Tom Leinster Says:

    Testing displayed formulas:
    latex \lim_\to \sum_{i = 1} n

  7. johncarlosbaez Says:

    Bummer, eh? Let me try:

    $e^{e + e} = e^e e^e $

  8. Tom Leinster Says:

    OK, that doesn’t work. Can we do displayed formulas?

    Let’s try another way. I don’t think this will work either.
    latex x = y

  9. johncarlosbaez Says:

    Okay, Tom: I put the “latex” right after the dollar sign, but it didn’t understand the double dollar sign so there are some extra dollars hanging on to the ends there…

    \[ e^3 = e e e \]

  10. johncarlosbaez Says:

    \[ latex e^3 = e e e \]

  11. Tom Leinster Says:

    Other mathematical bloggers (Tao, Gowers, Secret Blogging) must have figured out this basic stuff long ago.

  12. johncarlosbaez Says:


    Did someone install any of these various things for latex in WordPress yet?

    Like David?


  13. Tom Leinster Says:

    Well, what if we just put a formula in a paragraph by itself? Does it default to display style?

    E.g. here’s a sum inside text: \sum_1^n x_i. Here it is in a paragraph by itself:

    \sum_1^n x_i

    Any difference?

  14. Tom Leinster Says:

    There’s a basic FAQ on Latex in WordPress here:


  15. Urs Schreiber Says:

    On this page here is a description for how to get indented inline math in WordPress LaTeX. Seems one needs to install another plugin for that, called Ultimate \LaTeX. The link is given there.

    • math_reader Says:

      Urs, there’s a difference between a ready-made blog at wordpress.com (such as your new one), and a blog using the software developped by wordpress.org The plugin you mention is for folks who use the software on their own server.

  16. Tom Leinster Says:

    OK, let’s try a displayed equation, in display style, using the code at the [page](http://sbseminar.wordpress.com/including-equations-in-comments/) Chris Schommer-Pries linked to:

    $latex\ \ \ \sum_{i = 1}^n \frac{1}{n^2}
    \lim_{\varepsilon\to 0} \left( \frac{\pi^2}{6} + \varepsilon \right)$

    How’s that?

  17. Tom Leinster Says:

    Disastrous! The link failed too. Let’s try again:

    $latex\ \ \ \sum_{i = 1}^n \frac{1}{n^2} = \lim_{\varepsilon\to 0} \left( \frac{\pi^2}{6} + \varepsilon \right)$

    Any better?

  18. Tom Leinster Says:

    OK, here’s something simpler:

    $latex\displaystyle{\sum_1^n x^2}$


  19. Tom Leinster Says:

    Now I’m baffled. x. $latex\displaystyle x$. $latex\displaystyle{x}$. $latex\sum_1^n i^2$. $latex\displaystyle{\sum_1^n i^2}$.

  20. Tom Leinster Says:

    One more, and I’ll stop clogging up the comments thread. (But I’ll leave these experimental comments up in case anyone can see what’s wrong.)

    $latex\sum_{i=1}^{n} i^2$.

    $latex\displaystyle{\sum_{i=1}^{n} i^2}$.

  21. ursschreiber Says:

    you need a space after the “latex”.

    But as John noticed above, this “displaystyle”-command will not center the formula

  22. Chris Schommer-Pries Says:

    Let me try…

    \displaystyle{ \sum_{n=1}^{\infty} 1/n = \infty}

  23. Tom Leinster Says:

    Ah, thanks Urs. I usually put more spaces in my Latex than everyone else, but spaces can sometimes cause software to become confused, so I tried without. My mistake.

    OK, so I’ll try one more after all.

    \sum_1^n i^2.

    \displaystyle{\sum_1^n i^2}.

    \displaystyle{\ \ \ \sum_{i = 1}^n \frac{1}{n^2} = \lim_{\varepsilon\to 0} \left( \frac{\pi^2}{6} + \varepsilon \right)}

  24. David Speyer Says:

    My usual solution to the centering problem, which I will admit is painfully verbose, is

    \displaystyle{\sum_{n=1}^{\infty} \frac{1}{n^2} = \frac{\pi^2}{6}}

    That is to say,
    < p style=”text-align:center;” > $ latex \displaystyle{\sum_{n=1}^{\infty} \frac{1}{n^2} = \frac{\pi^2}{6}} $ < /p >

  25. David Speyer Says:

    But apparently that isn’t working here either.

  26. John Baez Says:

    Now my name is John Baez instead of “johncarlosbaez”.

    David and Simon: I suggest that you go to “My Account”, then “Edit Profile”, then change your “Display Name Publicly As” to your actual name.

  27. Urs Schreiber Says:

    I think it is good that math doesn’t come out perfect here. It should serve to remind you that if you go through the trouble of exposing a nontrivial piece of math discussion, it is a waste to do so just in a blog comment. You should do it on the nLab instead and point people there. 😉

  28. Mike Stay Says:

    \displaystyle \sum_{n=0}^{\infty} z^n = \frac{1}{1-z}

  29. CK Says:


  30. Tom Leinster Says:

    CK: you have to put the word “latex”, followed by a space, immediately after the first dollar sign.
