Mathematics Pronunciation Guide

A Megametamathematical Guide

of the

Proper American English Pronunciation of Terms and Names

for the

 for the Diacritically Challenged, 

        This guide includes most  mathematicians and mathematical terms that are encountered in high school and college.  Pronunciations of proper names are generally given as pronounced as in the original language.
        Some entries are obscure and may  be useful only in a game of mathematical trivia, e. g. d'Alembert's mother, the name of the line in a fraction, or the man who shot Galois.  I have not  included most definitions or accomplishments.  The curious person may try searching the internet for such information. 
       Dates include B.C. or A.D. only if the choice is not obvious from the context.
         The Guide is not complete, I am adding more pronunciations and entries as time permits.

         (The red dates and purple pronunciations are not links.)
      
        Please let me know about any errors.    Comments and suggestions welcomed.  Any help with missing dates and pronunciations will also be welcomed.
