Misha/Michael, thanks for having a look at the images! I am still wondering if this is the type of book Barbara was really looking for. I emailed her but I have not heard back from her yet. I don't want to do huge amounts of work (it took me 60 hours to scan that big cookbook, so I can imagine it would take at least that long to try to describe all of these math things) on this book if it isn't useful.
