text: The problem with this book is that it does not explain the mathematics well.  The author connects the unsolvable equation with group theory but does not provide any way for the reader to understand exactly what it is that is wrong with the equation.  Why could the equation not be solved?  There is a reason for this fact, and the mathematical theory explains it well--but not this book.  Perhaps a mathematician will write a book explaining why the 5th degree equation cannot be solved in general.  The reason is the subject of Galois theory taught in high-level mathematics courses but explainable in a popular book; but apparently not in this one
