I have a deep interest in mathematics, not least from formal training and I bought this book thinking that it might broaden my mathematical culture. This it certainly achieves as any thick volume of history of science invariably would, covering the subject chronologically, trying to frame each of these pieces of text from a human angle.
However, this rapidly gets formulaic, with a clear and repetitive pattern of writing, and pretty pictures that are not entirely relevant and not explained properly.
To be fair to the author, now that I have the book, it certainly looks like one of those coffee table tomes and it probably never was meant to be taken at a single reading, as I did. Each page of text, on its own, while hardly going into the detail of the maths, or even explaining in an insightful manner how this really fits into the body of work of mathematics, reads well.
So the treatment may not surprise or disappoint those with the expectation of light reading. It's just not aimed at readers with formal training in mathematics or a deep fascination with the subject.
