I really want to give this book at least 4 stars as I love the idea of encapsulating those great mathematical breakthroughs in one book and giving each a proper account instead of over simplistic summaries like many other math readings do.HOWEVER, the errors contained in this book is intolerable. It doesn't make sense anymore to give those mathematical details as you can hardly follow them due to the errors.For example, on page 5 it prints:If (2^n - 1) is a prime number then 2^(n-1)*(2^(n-1)-1) is a perfect number and that even perfect numbers must have this form.it obveriously should be 2^(n-1)*(2^n - 1) instead of what has been printed. As other readers have suggested, you would expect more similar errors along the way.Don't buy this book and wait for the 2nd edition if the publisher ever want to make an effort to make this book readable. I'm so very disappointed.
