A leading research mathematician presents a seriesf engaging and compelling mathematical statements with interesting elementary proofs These proofs capture a wide range f topics including number the. The author demonstrates his ability to proofs and "HIS INABILITY TO EXPLAIN HOW TO WRITE THEM I "inability to explain how write them I believe that anyone would find this helpful Even if you already have substantial training in mathematics this book is worth reading just for the elegance f the proofs Great book I recommend it for anyone who is interested in math Whether you are a beginner The Desert Princes Proposal or advanced you will surely find something in the book that catches your attention I was really blown away by this book Besides the ualityf the diagrams and illustrations which go far beyond any popular mathematics book I ve ever purchased the variety and depth The Makeover Prescription (Sugar Falls, Idaho of examplesf proof techniues purchased the variety and depth The Million-Dollar Question of examplesf proof techniues really impressive All my ld favorites like tiling a checkerboard and the mxn chocolate bar problem and many that I ve never seen before a proof that the number f different infinities is not any The Book of Pride of the infinities are beautifully illustrated and described in accessible but rigorous termsMy 7 yearld daughter looks The Hidden Kingdom (Wings of Fire Graphic Novel) over my shoulder when I m reading this book and asks lotsf curious uestions This book has been a great introduction to the beauty and wonder The Counts Blackmail Bargain of mathematics for this budding mathematician Excellent purchase especially like the mathematical habits sections which will surely cause a momentf reflection and will serve as conversation starters Proof and the Art Conscious of Mathematics is a wonderful book for multiple reasons firstf all it really does what it says n the cover namely to introduce aspiring mathematicians to the art f writing proofsThis is achieved through a combination Chosen by the Alien Lord (Rusneon Mates, of being walked through various elegant proofs selected by Prof Hamkins being asked to critiue mistaken proofs which contain some subtle errors but most importa. An introduction to writing proofs presented through compelling mathematical statements with interesting elementary proofsThis bookffers an introduction to the art and craft f proof writing The author. Work f Hugh Woodin However the point remains that Joel David Hamkins is an exceptional philosophically astute mathematician whose work I have enjoyed immensely that Joel David Hamkins is an exceptional philosophically astute mathematician whose work I have enjoyed immensely I was disappointed when I discovered severe errors early in the book I even e mailed the author and have received no replyDear SirOn page 3 you define the natural numbers as 0 1 2 3 In doing so by distinguishing natural number from 1 2 3 a definition which is common in many mathematical texts especially undergraduate textbooks in elementary number theory In addition you also explain that subtraction between
Two Natural Numbers Does Not Always Resultnatural numbers does not always result another natural number and use this as a justification for the integers Of course we could define subtraction in the natural numbers as cut ff subtraction which would allow subtraction between any two natural numbers however you make no mention f this mathematical Latin Lovers Greek Husbands Bundle operation in the text On page 10 you give Theorem 6 For any natural number n the number n2 n is even Clearly this is true and defined in the natural numbers as n2 is always eualr greater than nThe problem is in proof 2 by High school algebra in which you prove this theorem by rewriting n2 n as nn 1 n 1 is not always a natural number take n0 as your previous comments The Forgotten on page 3 pointut uite naturally some may consider this a minor uibble however as the text has made the definitions f natural number and subtraction although informal at least conceptually clear The proof as it stands fails in the natural numbersThis does not seem to be a misprint and this is my point as he makes a similar mistake n page 12 In short very disappointed and so cannot recommend the book I will not continue with the book and will be returning my copy.
