If you’re reading this shortly after it’s posted, you may notice ads for this book popping up in the sidebar and on top of the page. This is probably not entirely a happy coincidence– I was offered a review copy in email from the author and his publisher, and I suspect that they had ScienceBlogs on their radar as a likely forum for web publicity.<\/p>\n
With a title like The Drunkard’s Walk<\/strong><\/cite>, the book could be about one of two things, and the subtitle “How Randomness Rules Our Lives” pretty much rules out any Hunter S. Thompson style gonzo ranting. This is a book about probability and statistics, and how they are widely misunderstood and misapplied.<\/p>\n I jumped at a review copy of this because these are topics I don’t understand nearly as well as I should, and I was hoping for a nice accessible discussion of the topic. I wasn’t disappointed– Mlodinow writes clearly and compellingly about the basic rules of probability and how they apply to everyday situations. And his discussion of Bayesian statistics is the first thing I’ve read on the topic that makes it make sense.<\/p>\n <\/p>\n At times, I actually found myself wishing that the book contained more equations. Not because the writing was unclear without them, but because the plain-language explanations were better than anything else I’ve read on the subject. If I had had a textbook that put together detailed equations with explanations this clear, I would probably understand probability and statistics as well as I ought to.<\/p>\n The book mixes straightforward explanations of the basic concepts with historical anecdotes about the development of mathematical techniques for coping with randomness, going all the way back to the ancient Greeks. These include a few obvious people– Pascal, the Bernoullis– but also a number of less well known figures, or at least people who I had never heard of, like Cardano and Quetelet.<\/p>\n The book is also rich with references to recent applications of the key ideas, from the ever-popular Monty Hall problem to the economic studies of Kahneman and Tversky, to high-profile Hollywood studio firings and quirks of national lotteries. If there’s any weakness in the book it’s that these examples sometimes come a little too thick and fast, but he has a few repeating themes that he keeps returning to, and these serve to anchor the book pretty well.<\/p>\n All in all, I think this is an excellent layman-level introduction to the subjects of probability and statistics. Of course, I’ve already admitted the deficiencies of my knowledge in these areas, so it may be that people with a better background will find nits to pick, but as far as I can tell it is mathematically solid. And the writing is clear, easily readable, often funny, and never intimidating. I definitely recommend it to anyone looking for a fun book about the mathematics of random chance.<\/p>\n","protected":false},"excerpt":{"rendered":" If you’re reading this shortly after it’s posted, you may notice ads for this book popping up in the sidebar and on top of the page.
