| The Pea and the Sun: A Mathematical Paradox by A K Peters Too much history, too little content | I'm admittedly "overqualified" for this book, but I enjoy reading math books for non-mathematicians for inspiration and breadth. The first chapter on the lives and history of the people and theorems repeats the same teasers a number of times. It would be better to intermix the math and the history.
The theme of the book is nice, though, and it is the only one I've read that really addresses lots of seeming paradoxes about infinity in a way anyone could appreciate. By the time it gets to Banach-Tarski, there have been so many very similar theorems and so many teasers that it is actually quite a let-down. The bit on decomposition puzzles was quite fun, though, so this book is worth at least checking out of the library and skimming.
And on a mathematical note, the book's characterization of the Axiom of Choice as something you either accept or not is a total misrepresentation - there are numerous intermediate axioms (dependent choice, countable choice, etc) that allow lots of useful results, and you just need to indicate when you use one of them. | | The Pea and the Sun: A Mathematical Paradox by A K Peters you can grasp the idea behind the paradox | wapner made it clear and shift the argument from formal to non-mathematitians level.
i loved the review of set theory and cantor mathematics about arithmatic of transfinite,but the thing that was not clear in this book is "axiom of choice"
i highly advice this book for lay person who love the essence of math,especially counter-intutive one. | | The Pea and the Sun: A Mathematical Paradox by A K Peters It made my top ten list of best popular mathematics books | The Banach-Tarski paradox is a candidate for the most counter-intuitive mathematical result ever published. Basically, the conclusion of the theorem is that it is possible to decompose a small object into a finite number of pieces and then reconstruct the pieces a certain way to make two objects identical to the original. Phrased another way, it means that an object the size of a pea can be deconstructed into a finite set of objects that can be reconstructed in a manner to make an object the size of the sun. As bizarre as this sounds, the proof has stood up against all manner of assaults until there is no doubt that it is in fact true.
Wapner does an excellent job in setting the mathematical, historical and philosophical groundwork for explaining the theorem. The book starts with a brief explanation of the lives of Alfred Tarski and Stefan Banach as well as others such as Georg Canto and Kurt Godel who helped create the mathematical framework. This is followed by a lengthy and thorough discussion of the mathematical background needed to understand the theorem and the proof. It begins at the very basic level, so very little mathematical knowledge is needed before you begin.
The next step is the proof of the theorem, which by this time is very easy to understand. It is done step-by-step with not even the slightest "leap of faith." The final chapters deal with the consequences of the theorem. I found these chapters to be the most interesting in the book. In "Resolution", Wapner discussions the possible reactions to the theorem. They are:
*) Declare the result fallacious.
*) Accept the theorem at face value.
*) Reinterpret the result.
The first is not realistic as there is no longer any doubt that the theorem is true and the second is self-evident. Performing the mental gyrations necessary to accept the third option is the most interesting. Wapner resolves it by saying, "Yes, the theorem is true, but the actions needed to do something like duplicating a gold bar are not possible." Chapter 7, called "Real world" mentions some of the principles of quantum mechanics and how they can be related to the Banach-Tarski paradox.
This book is one that will fascinate you, it proves in the mathematical sense what you "know" cannot be true in the real sense. It also demonstrates a fundamental problem of philosophy, which is to consider to what extent a mathematical result can be applied in the real world. I loved this book, it made my top ten list of best popular mathematics books.
Published in Journal of Recreational Mathematics, reprinted with permission. | | The Pea and the Sun: A Mathematical Paradox by A K Peters Actually proves the theorem | | The book is wonderful because it actually proves the theorem in a way that a non-expert in mathematical foundations can actually understand. I wish all popular mathematics books were written at this level where the goal is to educate and entertain. Now as I suggested to the author all we need is a book like this one that will explain Godel's and Cohen's results on the independence of the continuum hypothesis. | | The Pea and the Sun: A Mathematical Paradox by A K Peters A fascinating introduction to the Banach-Tarski Paradox | The Pea And The Sun: A Mathematical Paradox is a fascinating introduction to the Banach-Tarski Paradox, a mathematical riddle that asserts it could be possible to create something as large as the sun by breaking a pea into a finite number of pieces and putting it back together again. Written to be accessible to lay readers and non-mathematicians, The Pea And The Sun outlines the history of the paradox, introduces readers to the basics of such matters as set theory, isometrics, scissors congruence and equidecomposability, and walks the reader through the theorem and proof that object duplication is indeed mathematically possible. But just because it is mathematically possible, is it physically possible? The highly counterintuitive nature of the mathematical theorem demands a critical response. A final chapter dwells on speculation as to how the Banach-Tarski Paradox may apply to the modern and future world. Written in a fresh, captivating, friendly style, The Pea And The Sun is remarkably engaging and will appeal to any reader with a discerning, inquisitive mind into the nature of the so-called impossible, regardless of their particular mathematical background.
| | The Pea and the Sun: A Mathematical Paradox by A K Peters Product Description | | Take an apple and cut it into five pieces. Would you believe that these five pieces can be reassembled in such a fashion so as to create two apples equal in shape and size to the original? Would you believe that you could make something as large as the sun by breaking a pea into a finite number of pieces and putting it back together again? Neither did Leonard Wapner, author of The Pea and the Sun, when he was first introduced to the Banach-Tarski paradox, which asserts exactly such a notion. Written in an engaging style, The Pea and the Sun catalogues the people, events, and mathematics that contributed to the discovery of Banach and Tarski s magical paradox. Wapner makes one of the most interesting problems of advanced mathematics accessible to the non-mathematician. |
