Word got out on MathJax a little early, as things tend to do on the web. We barely got a sample page up. Although it probably won't matter, our hope is you don't hammer MathJax too hard until we get things going and officially announce. Very soon now!

For the in-line version, is it possible to get the baseline on an equation to align with the baseline of the surrounding text? In your current demo page they are a bit off.

We've been using jsMath on our FogBugz wiki internally for a while now. I'm very glad this is going mainstream. It's a lifesaver for companies that use wikis and do math.

Re:Mathjax by mhartl on Tuesday December 15, 2009 @08:12PM (#997859)
Yeah, so this is basically awesome. I've written a LaTeX-based markup language that I'm using for my Ruby on Rails Tutorial book (http://www.railstutorial.org/book), but it's really designed for putting math & physics books on the web as HTML while still making nice PDFs. One big challenge I've faced is making nice HTML math typesetting, which I solved using texvc (the secret of Wikipedia's math typesetting), but unfortunately texvc is no good at inline math. I was not looking forward to solving that problem. Along comes MathJax, and now I don't have to!

N.B. Being able to benefit from unexpected advances like this is exactly why I standardized on LaTeX, even though it's kind of a pain to convert it to HTML. If you're trying to solve the math typesetting problem and not using LaTeX, you're on the wrong (coughMathMLcough) track.

MathML allows math to be rendered to speech for people with disabilities, something that LaTeX won't do. It is also a much more solid REPRESENTATION. It is not an input language like LaTeX. Think of LaTeX as YOUR favorite math UI, whereas MathML is an underlying representation. The fact that you can View Source and read it is immaterial.

Very exciting. This project looks impressive and I really hope it succeeds.

Also, what would be really orgasmic is if it would be possible to type math in Latex inside the browser and see it displayed nicely like that. But this is probably asking for too much.

MathML was supposed to be the answer, and we all know how that went. Just goes to show how over the top people were going with XML in the late 1990s. I mean,

  <math mode="display" xmlns="http://www.w3.org/1998/Math/MathML">
  <mrow>
    <mi>x</mi>
    <mo>=</mo>
    <mfrac>
      <mrow>
        <mo form="prefix">&#x2212;<!-- &minus; --></mo>
        <mi>b</mi>
        <mo>&#x00B1;<!-- &PlusMinus; --></mo>
        <msqrt>
          <msup>
            <mi>b</mi>
            <mn>2</mn>
          </msup>
          <mo>&#x2212;<!-- &minus; --></mo>
          <mn>4</mn>
          <mo>&#x2062;<!-- &InvisibleTimes; --></mo>
          <mi>a</mi>
          <mo>&#x2062;<!-- &InvisibleTimes; --></mo>
          <mi>c</mi>
        </msqrt>
      </mrow>
      <mrow>
        <mn>2</mn>
        <mo>&#x2062;<!-- &InvisibleTimes; --></mo>
        <mi>a</mi>
      </mrow>
    </mfrac>
  </mrow>
  </math>
to typeset the fucking quadratic formula?

MathML is not a human input language! MathML is a representation. While comparisons with TeX and LaTeX are inevitable, they serve different purposes. Look at the HTML/CSS used to render a dynamic menu sometime. I'm sure it is pretty ugly too.

Re:Mathjax by zackattack on Tuesday December 15, 2009 @07:26PM (#997774)
AJAX is not about XML anymore. A lot of people use XHRs with JSON. AJAX now refers to the dynamic phenomenon. So their name is indeed appropriate. Evolution.

XMLHttpRequest : XML :: JavaScript : Java :: Hamster : Ham

They never had anything to do with one another, it's just the module that Microsoft happened to dump it in.

Re:Mathjax by andreyf on Wednesday December 16, 2009 @01:35AM (#998244)

Not completely true... The X in XHR stands for XML, as that's what it parses natively [1], whereas parsing JSON wasn't native until relatively recently. JavaScript had Java's syntax. Not sure about hamsters and ham...

Re:Mathjax by blasdel on Wednesday December 16, 2009 @04:13AM (#998404)
From your link: "responseXML was introduced in Windows Internet Explorer 7" - in October 2006. XHR was first shipped with Internet Explorer 5 - in March 1999!

JavaScript's syntax is less like Java's than any other popular language that idiomatically uses curly-braces to delimit blocks.

Hamster starts with Ham, but they are as unrelated as two things can be that exist in the same broad category (flesh).

Re:Mathjax by andreyf on Wednesday December 16, 2009 @05:17AM (#998491)
Yeah... giving them the benefit of the doubt, that's misleading wording: XMLHttpRequest is an object in the JS namespace as of IE7. Before that, you needed to import an ActiveX Object, which has supported requestXML since MSXML 2.0 (that's IE5). See: http://msdn.microsoft.com/en-us/library/ms757066(VS.85).aspx

Isn't that kind of like SAT no longer standing for anything and it just being the name of the test now? Or, was that movie just making that up?
[ Parent | on HN ]
Re:Mathjax by blasdel on Wednesday December 16, 2009 @04:22AM (#998417)
No, it's more like if the SAT was partially named for the type of soil underlying the foundation of the building occupied by the school where the tests were first given, and then had its hype cycle fueled by shittily-paraphrased press releases from garden supply distributors.

It's Pataphor: http://en.wikipedia.org/wiki/%27Pataphysics#Pataphor
