What a bore! . This book is such a drag- not for the math bit, but the non-mathematical sections. The stories and ramblings are absolutely unnecessary, and detract from the substance. The problem is that the stories are inextricably intertwined with the math, and quite impossible to skip if you don't want to miss the math bit. To the extent I was able to drag on, the calculus portions seemed great, but it became too tiresome going through the flab. The great book on calculus has to be "How to enjoy Calculus" by Eli S. Pine- a book I regret not having known in my school days
