The Author's semi-jocular style does not deceive. This is a serious book and his deep reverence and love of the subject is not far below the surface.
At times I felt that he wrote for the more mentally equipped than the likes of myself, a mathematical voyeur. Thus in some respects he may appeal to the solver of puzzles and conundrums. He does, nevertheless,take you exploring for mathematical jewels and wonders as would a friendly and attentive tutor.
Despite a helpful publisher's note I could not fathom who Dr Googol is. He makes constant appearances throughout. Is he real? Is he a fictitious cartoon character brought in to provide artificial continuity? Is he the author in disguise? Some of his yarns might be true. The answer must remain within a closed circle of initiates.
After an initial struggle, I came to admire the layout of the book with its short chapters and its "Further Exploring" appendix which cleverly did away with awkward footnotes.
There is no question that the light-hearted manner assists understanding and there are many contemplative moments as well,the chapter on hyperspace prisons, for example, and the fine quotes from sages at the head of every chapter.
The author is modest, but you could not call him retiring or unenthusiastic. He is bursting with intelligence and knowledge with an unaffected desire to impart the same to others, which I found irresistible. Yet despite his efforts, I still felt an outsider. Perhaps he tried a little too hard, but he is not to be blamed for that. Five stars to him.
