then there is Xah.  Do you know of him? A plague, to many.  But I have 
always admired his Visual Dictionary work.

Note, in particular, that the dictionary is ordered with historical 
reference.  I am willing to accept it as my own perculiar sensibility, 
but math has its meaning to me largely through a view of its historical 
unfolding. I think it is a sensiblity that deserves a seat at the table.
