G n2 n as nn 1 n 1 is not always a natural number take n0 as your previous comments on page 3 point out uite naturally some may consider this a minor uibble however as the text has made the definitions of natural number and subtraction although informal at east 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 on page 12 In short very disappointed and so cannot recommend the book I will not continue with the

and will returning my copy This well written book by Professor Hamkins has a variety of interesting elementary mathematics And has many nuggets of wisdom eg the number 1 and prime factorization the usemention distinction with fractions and rational numbers and vacuous truth It s an excellent choice for aspiring mathematicians I was really blown away by this book Besides the uality of the diagrams and illustrations which go far beyond any popular mathematics book I ve ever purchased the variety and depth of examples of proof techniues is really impressive All my old favorites ike tiling a checkerboard and the mxn Chocolate Bar Problem And Many bar problem and many I ve never seen before a proof that the number of different infinities is not any of the infinities are beautifully illustrated and described in accessible but rigorous termsMy 7 year old daughter Academia Nuts looks over my shoulder when I m reading this book and asksots of curious uestions This book has been a great introduction to the beauty and wonder of mathematics for this budding mathematician.

## summary Proof and the Art of Mathematics

Proof and the Art of Mathematics is a wonderful book for multiple reasons first of all it really does what it says on the cover namely to introduce aspiring mathematicians to the art of writing proofsThis is achieved through a combination of being Walked Through Various Elegant Proofs Selected By through various elegant proofs selected by Hamkins being asked to critiue mistaken proofs which contain some subtle errors but most importantly by being provided with many carefully chosen exercises so that you can practise what you earn any craft reuires some personal effort At the very end of the book the author provides answers to some selected exercises where the you can compare your own proof attempts with model proofsOne big plus for me is the variety of mathematical areas covered you History of the Niagara Falls Power Company, 1886 1918, Vol 2 of 2: Evolution of Its Central Power Station and Alternating Current System; Construction and Operation ll find sections on topics such as the mathematics of the infinite number theory combinatorics real analysis and many a total of 15 topics Each section is sprinkled with bits of mathematical wisdom which are bound to improve the mathematical skills of anyone willing to attempt the exercises with them in mind The book also contains some very helpful coloured illustrations Also I ve had a positive experience with the delivery I received this book on my doorstep only one day after its release despite notiving in the UK The author demonstrates his ability to write proofs and his inability to explain how to write them I cannot believe that anyone would find this helpful The author of the book is a world class set theorist who probably than anyone else has promoted a multiverse realism in set theory This argume. An introduction to writing proofs presented through compelling mathematical statements with interesting elementary proofsThis book offers an introduction to the introduction to writing proofs presented through compelling mathematical statements with interesting elementary proofsThis book offers an introduction to the and craft of proof writing The author. Nt somewhat crudely advances the**point that the independence results obtained from the method of forcing suggest a multiplicity of**that the independence results obtained from the method of forcing suggest a multiplicity of theory universes similar to that of non Euclidian geometries In addition he has also advanced the idea that the phenomenon of independence can even be found at the evel of arithmetic I think he is wrong and my particular philosophical inch is better satisfied by the work of Hugh Woodin However the point remains that Joel David Hamkins Hugh Woodin However the point remains that Joel David Hamkins an exceptional philosophically astute mathematician whose work I have enjoyed immensely So 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 result in another natural number and use this as a justification for the integers Of course we could define subtraction in the natural numbers as cut off subtraction which would allow subtraction between any two natural numbers however you make no mention of this mathematical 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 eual or greater than nThe problem is in proof 2 by High school algebra in which you prove this theorem by rewritin.
