The Drunkard's Walk: How Randomness Rules Our Lives [Kindle Edition]

Leonard Mlodinow (Author)

Book Description

With the born storyteller's command of narrative and imaginative approach, Leonard Mlodinow vividly demonstrates how our lives are profoundly informed by chance and randomness and how everything from wine ratings and corporate success to school grades and political polls are less reliable than we believe.

 

By showing us the true nature of chance and revealing the psychological illusions that cause us to misjudge the world around us, Mlodinow gives us the tools we need to make more informed decisions. From the classroom to the courtroom and from financial markets to supermarkets, Mlodinow's intriguing and illuminating look at how randomness, chance, and probability affect our daily lives will intrigue, awe, and inspire.

Amazon Guest Review: Stephen Hawking
Published in 1988, Stephen Hawking’s A Brief History of Time became perhaps one of the unlikeliest bestsellers in history: a not-so-dumbed-down exploration of physics and the universe that occupied the London Sunday Times bestseller list for 237 weeks. Later successes include 1995’s A Briefer History of Time, The Universe in a Nutshell, and God Created the Integers: The Mathematical Breakthroughs that Changed History. Stephen Hawking is Lucasian Professor of Mathematics at the University of Cambridge.

In The Drunkard’s Walk Leonard Mlodinow provides readers with a wonderfully readable guide to how the mathematical laws of randomness affect our lives. With insight he shows how the hallmarks of chance are apparent in the course of events all around us. The understanding of randomness has brought about profound changes in the way we view our surroundings, and our universe. I am pleased that Leonard has skillfully explained this important branch of mathematics. --Stephen Hawking

From Publishers Weekly

A drunkard's walk is a type of random statistical distribution with important applications in scientific studies ranging from biology to astronomy. Mlodinow, a visiting lecturer at Caltech and coauthor with Stephen Hawking of A Briefer History of Time, leads readers on a walk through the hills and valleys of randomness and how it directs our lives more than we realize. Mlodinow introduces important historical figures such as Bernoulli, Laplace and Pascal, emphasizing their ideas rather than their tumultuous private lives. Mlodinow defines such tricky concepts as regression to the mean and the law of large numbers, which should help readers as they navigate the daily deluge of election polls and new studies on how to live to 100. The author also carefully avoids veering off into the terra incognita of chaos theory aside from a brief mention of the famous butterfly effect, although he might have spent a little more time on the equally famous n-body problem that led to chaos theory. Books on randomness and statistics line library shelves, but Mlodinow will help readers sort out Mark Twain's damn lies from meaningful statistics and the choices we face every day. (May 13)

5.0 out of 5 stars Excellent Book on Randomness in Everyday Life May 16, 2008

By G. Poirier

Format:Hardcover

I just love books like this - especially when they're as well-written as this one. The author, a physicist, proceeds to show the reader how randomness plays a much greater role in everyday life than one might think. As he discusses the basics of probability and statistics, he provides wonderful illustrations from fields as wide-ranging as sports, medicine, psychology, the stock market, etc., etc. He does an excellent job in driving home the fact that the true probability of events is not intuitive. Perhaps because of this anti-intuitiveness, I had to read a few paragraphs more than once to allow the point being made to sink in. One enigma that is particularly well explained is the Monty Hall (Let's Make a Deal) problem. The writing style is clear, accessible, very friendly, quite authoritative, engaging and often very witty. This book can be enjoyed by absolutely everyone, but I suspect that math and science buffs will savor it the most. By the way, the math-phobic need not fear: the book does not contain a single mathematical formula.

3.0 out of 5 stars Competent but unoriginal May 17, 2008

By David J. Aldous

Format:Hardcover|Amazon Verified Purchase

Promising prologue "... when chance is involved, people's thought processes are often seriously flawed .... [this book] is about the principles that govern chance, the development of those ideas, and the way they play out in business, medicine, economics, sports, ..." but a disappointing book. The book consists of a range of topics already well covered in a dozen previous popular science style books: history of probability (Cardano, Pascal, Bernoulli, Laplace, de Moivre) and of demographic and economic data; statistical logic (Bayes rule and false positives/negatives; Galton and the regression fallacy, normal curve and measurement error, mistaking random variation as being caused); overstating predictability in business affairs (past success doesn't ensure future success) and perennials such as Monty Hall, the gambler's fallacy, and hot hands.

These topics are presented in a way that's easy to read -- historical stories, anecdotes and experiments, with almost no mathematics. So it's a perfectly acceptable read if you haven't seen any of this material before before, but it doesn't bring any novel content or viewpoint to the table. Other books are equally informative and well written but have more interesting individual focus and panache:
Dicing with Death: Chance, Risk and Health shows hows to add analysis to anecdote,
Against the Gods: The Remarkable Story of Risk has more intellectual discipline (staying focused on the current topic),
Struck by Lightning: The Curious World of Probabilities gives a thorough treatment of implications of textbook theory,
The Jungles of Randomness: A Mathematical Safari gives snippets of contemporary research,
Chances Are: Adventures in Probability has less hackneyed history,
and Fooled by Randomness: The Hidden Role of Chance in Life and in the Markets is an engagingly opinionated view of chance in the stock market and life.

5.0 out of 5 stars Chances are good you'll like this one May 18, 2008

By Julie Neal TOP 1000 REVIEWERVINE™ VOICE

Format:Hardcover|Amazon Verified Purchase

This smart book will make you think. Academic yet easy to read, it explores how random events shape the world and how human intuition fights that fact. I found this point fascinating. It never occurred to me that our brains naturally want to see patterns and order, and life doesn't necessarily work like that.

It's comforting to think of an orderly world, with everything in its place, running according to plan. It dovetails into our yearning for meaning and control, and the need to feel that we are important. The idea of randomness is frightening. If the world is shaped without conscious decision, it's a pretty chilly prospect.

Author Leonard Mlodinow examines the importance of randomness in diverse situations, including Las Vegas roulette tables, "Let's Make a Deal," the career of Bruce Willis, and the Warsaw ghetto after Hitler invaded Poland. The author does a good job explaining how chance and luck are vital factors in how things turn out.

The cover has a nice touch. On the dust jacket, several die-cut holes reveal letters on the hardback underneath. The letters are the R and D in "Drunkard's," the A in "Walk," the N in "Randomness," the O in "Our" and the M in Mlodinow. These letters are connected by a thin red line. They spell out "RANDOM."

Here's the chapter list:

1. Peering through the Eyepiece of Randomness
2. The Laws of Truths and Half-Truths
3. Finding Your Way Through a Space of Possibilities
4. Tracking the Pathways to Success
5. The Dueling Laws of Large and Small Numbers
6. False Positives and Positive Fallacies
7. Measurement and the Law of Errors
8. The Order in Chaos
9. Illusions of Patterns and Patterns of Illusion
10. The Drunkard's Walk
