Book SynopsisEnables anyone with basic math and science skills to estimate virtually anything - quickly - using plausible assumptions and elementary arithmetic. This book presents an array of estimation problems that range from devilishly simple to quite sophisticated and from real-world concerns to silly ones.Trade Review"Dr. Adam and his colleague Lawrence Weinstein, a professor of physics, offer a wide and often amusing assortment of Fermi flexes in a book that just caught my eye, Guesstimation: Solving the World's Problems on the Back of a Cocktail Napkin."--Natalie Angier, New York Times "An important skill of great use ... is the ability to derive an approximate result from insufficient data. Guesstimation is a collection of [problems] gathered from everyday life and various fields. Working out questions ... is both entertaining and enlightening. It may also help foster your career ... because making correct guesses quickly establishes your reputation as an expert."--Stephan Mertens, Science "This book is a stimulating collection that will help the reader to reach informed judgments and will be a useful source of inspiration for mathematics and physics teachers: my only concern is that if my students have read it before they arrive at university, I may have to find a new approach to my first day's teaching."--Tony Mann, Times Higher Education "While few can hope to emulate the brilliance of a Nobel Prize winner like [Enrico] Fermi, coming up with pretty good guesstimates is a skill that can be taught. And that's the aim of Guesstimation. After a quick tutorial, the authors get down to business with a host of wide-ranging worked examples, from estimating the numbers of piano tuners in Los Angeles to figuring out the impact of deforestation on greenhouse gas levels. The results are sometimes surprising."--Robert Matthews, BBC Focus Magazine "[Guesstimation is] a left-brain book that helps you approximate answers to the types of questions actually asked in some job interviews today."--Peter Coy, BusinessWeek "[A] delightful account of mathematical approximation, which instills the beauty and power of the back-of-the-envelope calculation. The puzzles make addictive confidence builders by breaking down tricky questions into manageable parts. Never again will you take a newspaper figure at face value without feeling the need, and confidence, to guesstimate your own figure."--Matthew Killeya, New Scientist "Guesstimation is both enlightening and entertaining. I recommend it to my fellow journalists both as a tool of our trade and as a mind stretcher."--Rony V. Diaz, Manila Times "Any idea what fraction of land in the US is covered by either a roof or pavement? Known as a Fermi problem, this type of question requires the use of reasonable estimation, which is the focus of the book at hand. In the initial chapters, Weinstein and Adam briefly review good 'guesstimation' techniques involving numbers and explain why the use of the geometric mean is preferred over the arithmetic mean."--J. Johnson, Choice "How many people in the world are picking their nose right now? Weinstein and Adam 'guesstimate' the answer to this problem and 79 others, covering chemistry, physics, biology and history. The book is a step-by-step guide to problem-solving using rough-and-ready maths, the kind done on the back of a cocktail napkin. And the authors have kindly left additional questions at the end to get readers started on their own problem-solving expedition."--Cosmos "Physics educators can use this book as a guide to including the important skill of estimation in their courses. Students may find the power of estimation to be a valuable skill and will want to work their way through this book."--Arthur Eisenkrafr, American Journal of Physics "A source of imaginative problems, this book would make a nice addition to a mathematics department library."--Diane Resek, Mathematics Teacher "[I]t's quite obvious that the authors intend their book to be fun, nonthreatening, and user-friendly. There's very little not to like... [T]he book can be for everybody, 'higher-up professionals' who might know math but not physics, as well as students wrestling with 'word problems.' Teachers could very well recommend it to math majors and nonmajors alike, or even use it in the classroom, in some cases as supplementary reading for the course."--Marion Deutsche Cohen, Mathematical Intelligencer "The cumulative effect of fairly simple paths to estimating solutions to a dizzying array of difficult problems is fascinating."--Ray Bert, Civil Engineering "This book will be enjoyed by anyone with an interest in estimation, but is also targeted at those applying for jobs at companies like Google, where the kind of questions considered in the book are often used in the interview process."--Paul Taylor, Mathematics TodayTable of ContentsAcknowledgments xi Preface xiii Chapter 1: How to Solve Problems 1 Chapter 2: Dealing with Large Numbers 11 2.1 Scientific Notation 11 2.2 Accuracy 14 2.3 A Note on Units 16 2.4 Unit Conversion 17 Chapter 3: General Questions 19 3.1 One big family 21 3.2 Fore! 25 3.3 This is a fine pickle you've got us into, Patty 29 3.4 Throwing in the towel 31 3.5 Hey buddy, can you fill a dome? 35 3.6 A mole of cats 39 3.7 Massive MongaMillions 41 3.8 Tons of trash 43 3.9 Mt.

Book SynopsisMagical Mathematics reveals the secrets of fun-to-perform card tricks--and the profound mathematical ideas behind them--that will astound even the most accomplished magician. Persi Diaconis and Ron Graham provide easy, step-by-step instructions for each trick, explaining how to set up the effect and offering tips on what to say and do while performTrade ReviewWinner of the 2013 Euler Book Prize, Mathematical Association of America Honorable Mention for the 2012 Award for Best Professional/Scholarly Book in Popular Science & Popular Mathematics, Association of American Publishers "[F]ascinating... Magical Mathematics [is] a dazzling tour of math-based magic tricks... Lovers of recreational mathematics, and especially fans of the late Martin Gardner, who contributed the foreword, will find many pleasures in Magical Mathematics. And while exposing magic secrets in a book intended for the general public may raise hackles among some old-guard magicians, exploring the math behind these tricks will, in truth, only deepen the mystery. For, as the authors remind us, sometimes the methods are as magical as the tricks themselves."--Alex Stone, Wall Street Journal "The Riemann hypothesis, the Mandelbrot set, Fermat's last theorem--these mathematical notions and others underlie all manner of magic tricks. Mathematicians Persi Diaconis--also a card magician--and Ron Graham--also a juggler--unveil the connections between magic and math in this well-illustrated volume."--Scientific American "Writing for the public, the two authors share their passions, teaching sophisticated mathematical concepts along with interesting card tricks, which rely upon those principles for their workings."--GENII: The Conjurors' Magazine "[I]t is simply a beautiful book. The design, layout, typography, even the paper is beautiful... [T]his is one of the most fun, engaging new popular mathematics books I've seen in a long time."--The Math Less Traveled Blog "The authors are master storytellers... [T]he authors offer advice and recommendations for further pursuits in mathematics, magic and juggling."--Cut-the-Knot blog "Well known and highly respected in the mathematical community, Diaconis and Graham have produced a work that completely lives up to expectations. It contains descriptions of magic tricks as viewed by an audience, the mathematics that make them possible, and clear explanations to help you--with a little practice--amaze your friends."--Library Journal "Magical Mathematics gives readers a peek behind the velvet curtain that hides the magician's secrets... The book covers some nifty card tricks, juggling, codes and a slew of mind-bending puzzles. The book doesn't just tell you how to fool and impress your friends with parlour tricks, it explains why these tricks work, so that you can go on to devise your own--in fact, the authors challenge you to do just that. The writing is lively and the tricks are well set-up, providing newbie magicians with both points of view: what the audience sees and what the magician knows."--Montreal Gazette "Magical Mathematics is an absolutely remarkable book. I don't say this lightly. Publishers send me plenty of books to review. Some I like more than others. Magical Mathematics is a fantastic book for someone who wants to explore the non-trivial math behind some impressive magic tricks. While I enjoy purely recreational math puzzles that have no practical application I also love it when I discover challenges that are interesting and relevant. Magical Mathematics is chock full of fun (and deep) challenges that students (and adults) can sink their teeth into."--Wild About Math blog "Over 12 chapters, the reader is taken on a unique and wonderful tour that fuses magical tricks with underlying mathematical explanations and personal stories, written by world-renowned experts in both fields. With its friendly, disarming style, the book is pitched perfectly at a level that will surprise both the hardened mathematical researcher and the interested general reader, without putting either of them off... [T]his book is a must-buy."--C.J. Howls, Times Higher Education Supplement "The first chapter of this book begins by teaching a simple four-card trick and ends by presenting--complete with step-by-step color illustrations--a more complicated card trick that will truly amaze any audience. Both tricks are based on mathematical principles, and the book goes on to explain these and many other principles that can be the basis for a variety of clever magic tricks."--Games magazine "Learn the secrets behind card tricks, including step-by-step instructions for performing them, along with the mathematical ideas the tricks illustrate."--Science News "As magic books go, Magical Mathematics is erudite, thought provoking, inspiring... It is the product of multiple decades of work and research, and for a small subset of magic enthusiasts it could rank as the best book they buy this decade."--James Alan, Magicol "There is so much to digest in this book that it is impossible to describe even a fraction of it in just a few paragraphs. Let it suffice to say that if you are at all interested in card magic principles, how they work, why they work, and the history behind them, to ignore this book would be a serious mistake."--Peter Duffie, Magic magazine "From arcane theories to practical tips for working magicians, the authors go behind the curtain and reveal how the pros do it."--San Jose Mercury News "The connection between magic and mathematics has a long and intriguing history, and throughout their book Diaconis and Graham present detailed and fascinating insight into that history... Overall, the book is a wonderful introduction to this esoteric area, but has more than enough depth to entertain and enlighten the knowledgeable. Perhaps most important of all, it shows how deconstructing illusion can provide fascinating insight in the nature of reality."--Richard Wiseman, Nature Physics "Magical Mathematics strikes a nice balance between descriptions of performable magic tricks and the mathematics that makes them work. Unlike some 'mathemagic' books, in this work, Diaconis and Graham describe magic tricks that are actually used by professionals... [T]he writing is engaging, and learning the tricks that are presented is well worth the effort... This volume should find a place in any mathematics or magic library collection."--Choice "While turning the last pages, the reader is bound to feel touched and charged up and would definitely be moving in an altered direction, for this is a book that will not just leave an impression, but will also suggest which path to take next."--Shubashree Desikan, Current Science "Reading Magical Mathematics ... had ... [a] powerful effect on me. I was transported to a strange and shadowy world of card tricks and magic that, at the same time, was miraculously a land of mathematics, a land with substance... Barely ten pages into the book I am completely hooked."--John J Watkins, Mathematical Reviews "The authors have produced an invaluable contribution to the fascinating relationship between magic and mathematics... The authors exhibit a lifelong passion, enthusiasm and deep knowledge for magic and mathematics and this is an ideal combination for producing a great read... I highly recommend it to anybody interested in the mathematics behind some impressive magic."--Fiacre O. Cairbre, Irish Mathematical Society Bulletin "Mathematical Magic is a truly magical book, containing ample amounts of mathematics and magic that will amaze and amuse. Diaconis and Graham are both first-rate mathematicians and performers and offer insights and ideas that could not have been expressed by anyone else. This book is destined to be a classic on the subject."--Arthur Benjamin, SIAM "This is a splendid book with lots of wonderful insights... Give this book a try; you certainly will not be disappointed."--Phil Dyke, Leonardo Reviews "While there are other books out there detailing the relationship between mathematics and magic, this book is perhaps the best written of them all, as it will appeal to magicians, math buffs and general readers alike."--R.
