Excellent. That sounds like a good solution, then.

Dumb pixels won't take advantage of the medium. Reading on a computer, I'd like to plug in some values, and get a sense for what a reasonable range of answers is.
The information that makes it an equation could be pasted into a different application that lets you combine with other equations, rearrange terms, check for consistent units, plot results, etc. I'd learn a lot more that way! |

Three standard math programs which engineers and scientists use are Mathematica, Matlab and Mathcad. Each has its own syntax. Favoring MathML as a standard would upset the other two vendors. When you throw in spreadsheet software or even a standard language like Fortran or C, you have another can of worms, due to function naming.
None of the three core programs displays equations in a pretty format, not even for simple matrices. That would involve another standard, with "typesetting" thrown into the consideration. Since any given equation can result in a number of renderings, where do you stop the process of "beautifying" the resulting graphic image? This is why I always spend a lot of time adjusting the positions of symbols when I write a technical paper. I know, this is terribly backward. It leads to errors, since an author may have already validated an equation in his/her math app, only to see a sign added/omitted in the published version, which he probably generated in a word processing app. And don't expect a reviewer to catch the error. It's frustrating. |

For typesetting, mathematicians tend to use LaTeX anyway, no? For ePub though it seems more natural to use a variant of XML. |

Fat Abe, if you were using LaTeX (and all of those programs can export to LaTeX format ---MathCAD needs an external utility) this wouldn't be an issue. All three programs have varying abilities to natively export to MathML (believe me, _no one_ wants to write MathML out by hand).
http://www.lyx.org is a nice graphical front-end to LaTeX which you really should try. William Last edited by WillAdams; 04-14-2010 at 11:06 AM. Reason: noting MathML tool support |

And yes, MathML is an open standard developed by the W3C. Also, the "XML Entity Definitions for Characters" has just been adopted as a W3C recommendation, and as a required element alongside MathML in ePub should allow easier universal display of formulae. |

I was interested in the content part, as another user thought it would be prudent to design in a syntactical representation of a formula, say y= m*x+b, where the reader would be able to manipulate m or b, and then to see the result graphed in the document. Is W3C thinking this far ahead? We'd all like to write once and deploy everywhere.
I had a question about the path from Content -> Presentation. Is this up to the provider of the translator software? Last edited by Fat Abe; 04-14-2010 at 12:52 PM. Reason: Typo |

Yes, one can do that sort of thing, but none of the static document formats allow for it, AFAIK, one has to use a programming environment --- best example of that would be _Euclid's Elements_ Joyce's Java Version:
http://aleph0.clarku.edu/~djoyce/jav.../elements.html Or maybe SVG, but I'm not aware of a document-viewing tool which allows the more dynamic aspects of SVG w/o back-end server support. William |

There's no "->". They're different forms of the standard, intended for different uses, and both are fully displayable. (I'd stress that MathML is purely a display language, you do the layout in your choice of editors and then convert)
