Excellent!  This book is so dense with information, you will have to take notes to remember who did exactly what when.  The historical derivations of certain math tricks we take for granted fill in the gaps left by most math course.  A superb addition to any math teacher/professor's shelf.<br>My only fault in it (and it my be my mistake) is that the years given for the founding of various universities are largely wrong.  Perhaps my other sources are the ones at fault, but I thought it odd that this text disagrees with nearly all universities on their own founding years.  Oh well.  A minor point.
