Max Gunther's classic text brought back into print. Luck. We can't see it, or touch it, but we can feel it. We all know it when we experience it. It's an obvious description of obvious events. 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 richly anecdotal ride through the more popular theories and histories of luck - from pseudoscience to paganism, through mathematicians to magicians - Max Gunther arrives at a careful set of scientific conclusions as to the nature of luck, and the possibility of managing it. Based entirely on 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 which 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.
