Stephen Hawking says "very readable". (2008-09-25)

I have read some very complicated material in my days, but my first clue should have been Hawking's comment. What is very readable to him will not be to the average person. No doubt some will find it fun, but just so you know it is NOT an easy read by any means, and after a few chapters I gave it away, since I could see no reason to read more: I got his point by then. It's too "random" and full of his theories on things.

Excellent Anecdotal Introduction to How Randomness Fools Us (2008-08-14)

Have you ever flipped a coin 100 times to see the sequence of heads and tails that comes up? If you have, you know that there can be long streaks of heads and tails. Random results that end up 50-50 don't look that way in the short term.Human perception is such that we like to find patterns where none exist. I remember the CEO of a company I worked for would draw a trend line through one data point with great authority, totally unaware of what he was doing.More often, we judge by samples of behavior and time that are too short to be representative. Professor Mlodinow does a good job of showing how executives are often fired just before they get their best results, and how seldom the new executive does any better than the prior one.In sports, we get all excited about streaks. Professor Mlodinow dampens that enthusiasm by pointing out that like streaks can occur randomly. We need to check to see if the streak exceeds the expected degree of variation before deciding that something significant has taken place. (But don't stop cheering on your favorite team and players.)The book also provides lots of thumbnail sketches of the human side of those who have advanced the science and math behind our ability to measure and understand randomness. In fact, I don't recall a book on this subject with better anecdotes about the scientists and mathematicians. That's the reward in this book if you already know about randomness.If you know nothing on the subject, this book is the gentlest possible introduction.Enjoy!

Excellent Book on Randomness in Everyday Life (2008-05-16)

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.
