<p>I sometimes browse the site on an iPad (16GB no 3G) using Safari and have noticed that many of the LaTeX equations are not rendered properly on stats.SE but are on other sites including the MathJax website and others: <a href="http://www.leancrew.com/all-this/2010/07/how-many-samples/" rel="nofollow">Example</a> (chosen because it uses \hat which doesn't display properly on stats.SE). </p>

<p>Here are a couple more examples:</p>

<p>$$\hat{x}_n$$</p>

<p>$$\hat{\rho}_j$$</p>

<p>$$\langle x, y \rangle$$</p>

<p>Can anybody reproduce this and is there any fix?
Is it due to a font choice on stats.SE?</p>

<p><strong>Edit</strong>: I checked math.SE and it has the same issue. MathOverflow does not. I'll try to post screenshots later if that would help. </p>
