Wow, well, the equations scanned very well. That would be the good news. I've fixed a few simple equations in a couple books so they would be easier to convert, but nothing like these. As a sighted (sort of) meteorologist these are quite complex equations. Apparently this is a very technical book on how to design bioptics rather than a popular book about how a person might use them. I know there is a math braille (called nemeth), but that would mean the brf copy of the book would have to be created separately from the daisy version. And for the Daisy version the equation would have to be written out in words. I did find a page online by Professor Nemeth that describes an efficient way to speak math http://www.rit.edu/~easi/easisem/talkmath.htm Again, that would take a lot of "translation" to type in the spoken version of each equation. It would be useful to know what publishers that are supposed to be adding textbooks directly to bookshare do for complex equations. So, I, at least, don't have a real answer of what to do. I'd send the scan files directly to John Glass or volunteer@xxxxxxxxxxxxx with the question about what to do. But, I've only been validating for a few months so maybe someone else knows more.
