Query: Errors detract from material.

As an introductory Nuclear Engineering or Nuclear Physics textbook, the book fulfills only the minimal requirements. There are none of the marks of a thoroughly constructed book, such as separate sections with supplementary information. These faults were all excusable, until the list of mistakes and typos began to develop. It is inexcusable how blatantly incorrect some of the formulas are in this text. The book needs a serious once-over for corrections.
