== Mathman ==
I saw your posts[http://lists.squeakland.org/pipermail/etoys-dev/2011-January/006025.html] yesterday at etoys-dev about http://mathman.biz
Have you read Ed Cohen's books ''Calculus for Young People''? I haven't (I only browsed the free of charge sample problems on the web) and I am curious if you have, and what your review of it is.

:Did you make any progress in encouraging Mathman to publish with an open license? I have yet to read an independent review of his work. --[[User:Dcorking|dcorking]] 16:19, 9 April 2011 (EDT)
