Excellent Book on Randomness in Everyday Life,
By
This review is from: The Drunkard's Walk: How Randomness Rules Our Lives (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.

What, we don't have control of our existence?,
By
This review is from: The Drunkard's Walk: How Randomness Rules Our Lives (Paperback)
We all like to think that we determine our own destiny, that we are the all-mighty purveyors of our success and failure, that through the illusion of control we can gain an understanding of all cause and effect to our existence. How about the success of Bill Gates or Mark Zuckerbergs of the world Surely, they are deserving of the billions of dollars they have earned and the accolades that have been poured down on them. Mr. Mlodinow will argue otherwise. Our successes and failures have more to do with chance and stubborn stick-to-itiveness than anything having to do with cause and effect. When we get a lucky break, that's exactly what it is, a lucky break. The numbers will prove this to be so. Mr. Mlodinow argues that our ability to understand the past is practically perfect but our ability to predict the future using those same cause and effect indicators is very poor. In fact, chance and random numbers would be a better predictor. When the performance of Mutual Fund managers is measure against the performance of random numbers, the result is the same. Individual behavior mirrors that of the drunkard's walk, the path of an individual molecule as it travels through a gas or liquid. We can only predict the probability of a certain behaviour, not its final outcome. Our own path through life involves a series of chance events that have lead us to where we sit at the present moment. To think back and understand that existence as having been determined by individual factors from the past is to suffer from the illusion of control. We like to think we have it. In fact, our very existence can depend upon it but in point of fact, it doesn't exist. The likelihood of publishing that book or getting that next promotion or finding that perfect partner has more to do with chance than anything to do with what we can control so we'd rather pretend than accept.

Not what I expected, but pleasantly surprised nonetheless.,

This review is from: The Drunkard's Walk: How Randomness Rules Our Lives (Paperback)
Excellent book on the history of statistics. Mlodinow does a beautiful of job of going through a basic course in statistics with insightful applications, while looking at the lives of some of the mathematicians and scientists that contributed to the field. Good writing and captivating story-telling.The last chapter was a tad disappointing, the conclusion was approached from more of a psychological perspective as opposed to the mathematical approach to sociology that I was expecting. If you are interested in some of the psychological biases that the author explores in the last chapter I recommend 'Predictably Irrational' by Dan Ariely as well.
