Max Gunther's classic text with a new foreword by Gautam Baid. Luck. We can't see it, or touch it, but we can feel it. We all know it when we experience it. But does it go deeper than this? And if it goes deeper, does it do so in any way which we can harness to our own and others' advantage? Taking us on a fascinating tour through the more popular theories and histories of luck ? from pseudoscience to paganism, mathematicians to magicians ? Max Gunther arrives at a careful set of scientific conclusions as to the true nature of luck, and the possibility of managing it. Drawing out the logical truths hidden in some examples of outrageous fortune (and some of the seemingly absurd theories of its origins), he presents readers with the concise formulae that make up what he calls the 'Luck Factor' ? the five traits that lucky people have in common ? and shows how anyone can improve their luck.
