Lectures on Quantum Theory: Mathematical and Structural Foundations
"The proper role of mathematics is to make things easy. When something can be expressed in the precise language of mathematics, results can be obtained by the application of given rules. Calculations are so simple that even computers can do them. Chris Isham's lectures on the mathematical and structural foundations of quantum theory, reproduced in this book, provide an excellent illustration of this truth ... a welcome addition to the modern literature on quantum theory ... It is good to have a book that gives such an excellent description of the mathematical structure of quantum theory ..."
