I'm looking for a complete dictionary about Mathematics, after searching a lot I found only this one http://www.amazon.com/Encyclopedic-Dictionary-Mathematics-Second-VOLUMES/dp/0262090260/ref=sr_1_1?ie=UTF8&qid=1323066833&sr=8-1 .
I'm looking for a book that can give me a big picture, well written with a clever idea in mind from the author, a big plus can be the presence of railroad diagram or diagram with logic connections between the elements.
