But in gambling's history, no one had created a system that could guarantee a win on the roulette wheel--until Doyne Farmer and Norman Packard came along. In 1975, two childhood friends and physics geeks embarked on arguably the most ambitious Vegas-cheating project of all time: to deconstruct the physics behind the motion of a roulette ball, and build a miniature computer system that could surreptitiously predict the outcome of a roulette game.

Thanks in large part to the iron will of Caesar, the Romans complete their long quest for total Mediterranean dominance, defeating the Gauls in the final battle of the Gallic Wars. For a period of time though, Gallic victory seemed possible. Out-numbering the Romans five to one, they held the high ground, on the hilltop fortress city of Alesia.

Before Lincoln finally came to rest in a steel-and-concrete-reinforced underground vault in Springfield, the President's body was repeatedly exhumed and moved, his coffin frequently opened. In 1876, eleven years after Abraham Lincoln's assassination, a band of Chicago counterfeiters plotted to steal Lincoln's body and hold it for ransom. Their plan was to demand $200,000 and the release of the gang's master engraver, who was in prison in Illinois. The Secret Service--recently formed to deal with the country's ballooning counterfeiting problem--infiltrated the gang with an informer. It also set in motion a cringe-inducing chain of events in which a group of well-intentioned, self-appointed guardians took it upon themselves to protect Lincoln's remains by any means necessary. This strange story of Lincoln at un-rest reveals how important this man was to so many, and perhaps our reluctance to let such a beloved and visionary leader go. TVPG VL | CC

Vegas cheats come in all shapes and sizes: hardcore mechanics who devise gadgets to manipulate slots and mathematical geniuses who count cards in blackjack. But in gambling's history, no one had created a system that could guarantee a win on the roulette wheel--until Doyne Farmer and Norman Packard came along. In 1975, two childhood friends and physics geeks embarked on arguably the most ambitious Vegas-cheating project of all time: to deconstruct the physics behind the motion of a roulette ball, and build a miniature computer system that could surreptitiously predict the outcome of a roulette game. The project soon became an out-of-control obsession, consuming a whole commune of brilliant hippie-physicists...and ended in a landmark contribution to modern-day Chaos Theory.
