As someone who took a lot of math courses in college (not always doing very well, but always being intrigued), this book was absolutely in my wheelhouse and even better, it was more engaging than many novels that I've read. I was constantly chuckling and snickering at the many revelations and stories that were shared. I thought the majority of it was easy to understand (perhaps not always easy to accept) but I suspect some will lack the self confidence to read it - I hope these folks are not put off. At the end he has a brief section on the many people who abandon mathematics because they think they are not "gifted" or "genius" enough, and pleads the case that we all need to be mathematicians. So I guess I am exonerated. There are several stories of people who pursued a question for their life, only to have it advanced by the next generation. So interesting that many of these questions arose from real world questions and concerns and not so much from abstract noodling.<br><br>I agree to an extent with some reviews that for a serious mathematician who might read textbooks, this isn't as systematic and direct as it might be, but on the other hand, I thought the writing was among the best and most engaging for non-fiction that I've seen.  If you might fit in this picture and are willing to open up your imagination a bit, I think you'll find this book as entertaining and enlightening as I did.
