Is there some Calibre plugin to convert scientific articles with math formulas to epub or mobi?

  I'm guessing that's a very hard problem, but I'd love to hear otherwise. If you go the standard route: write in latex then pdflatex, you have no information in the pdf as to what those symbols are, right? So this is pretty close to mathematical ocr, with all of the weird symbols that math alone uses and the various meanings of different lengths of underbar or overbar in the article. Am I wrong? Is there more information left in the pdf? Obviously you can just extract images from the pdf and put that into epub, but it's a crappy solution at best. For a long time, I've wished for something that could ocr handwritten math and make even a shitty pass at ocr-ing to latex. There appears to be no such software. I doubt there's a big market, but there are a lot of people being paid $15+/hour to latex up written math...

    I think that the solution is much more simple. Print formula > Convert formula to image (screencap) > Paste image

      the whole point is to have vector math, not raster, particularly to well support zooming in and out on small devices

        Rasterize at 900dpi, then? Even on small devices that would support a ~3x zoom without compromising visual quality versus vector. In EPUB3 readers with full <canvas> support one can translate the paint primitives via pdf.js into JS, too.
