[Blindmath] Calculus, Mathematica, and the Macintosh

Sun Jan 26 16:40:22 UTC 2014

A good idea about having some Mathematica accessibility info on the Access2Science site.  The editors have put up most of what they know, but we are really happy to have contributions on science accessibility topics.

So Kyle, will you please write up an article on Mathematica accessibility, and Theodor, maybe you'd contribute a short article from a user's perspective.

@Sean

In case you get this book, please keep us updated! :)

@sina

I agree that we should have a more organized place to retrieve all the
good information that we get on this list... the  access2science.com,
I think, does not have anything related to matematica accessibility,
does it?
