An Informal Introduction to the Mathematics of String Theory for the Casual Student

Based, principally, on Dr. Barton Zwiebach's text book "A First Course in String Theory". I have selected key concepts, re-arraigned the order of presentation and added substantial detail to the exposition. While Prof. Zwiebach's book makes string theory accessible to under-graduates, it is not ideal for self study by the casual student of string theory.
