    Aczel turns his sights on probability theory -- the branch of mathematics that measures the likelihood of a random event. He explains probability in clear, layman's terms, and shows its practical applications. What is commonly called luck has mathematical roots and in Chance, you'll learn to increase your odds of success in everything from true love to the stock market. For thousands of years, the twin forces of chance and mischance have beguiled humanity like none other. Why does fortune smile on some people, and smirk on others? What is luck, and why does it so often visit the undeserving? How can we predict the random events happening around us? Even better, how can we manipulate them? In this delightful and lucid voyage through the realm of the random, Dr. Aczel once again makes higher mathematics intelligible to us.

    On March 2nd, 2000, the technology company 3Com spun off its insanely profitable hand-held computer subsidiary, Palm. It was one of the most fascinatingly high profile and complex and bungled trades in history, but All The Evil Of This World isn't about the millions and millions of dollars that instantly came into play, it's about seven separate voices from seven separate individuals (an ambitious low-level clerk fresh out of school, a drug-addicted, party-throwing broker with bad taste and gross amounts of money, a seemingly infallible hedge fund manager tortured by his own good luck, to name a few) and the 3Com/Palm trade is what weaves their stories together. They all collide into it and out of it, and it sometimes unites them, implodes them, saves them, or destroys them.This book is not for the faint of heart--these characters are just as troubled and intense and volatile as their surroundings, and the writing pulls not a single punch--but it's an unrelenting examination into a cast of characters that we rarely examine fairly or patiently, and who we often find it easy to dehumanize. The people who inhabit this world aren't cartoon heroes or villains--as it turns out, people who happen to handle large amounts of money for a living--are just people, with shortcomings, just like us.
