The full paper is now available. It takes the precession of a tossed coin into account when doing its analysis, and among other things has some nice pictures of coin-tossing machines.
The following section made me wonder (emphasis added):
Poincare's arguments suggest that as a roulette ball is spun more and more vigorously the numbers become closer and closer to uniformly distributed. There are numerous studies ( [Barnhart, 1992], [Bass, 1985]) suggesting that real roulette may not be vigorous enough to wash out the initial conditions.Hmm. So I'm writing my grant proposal for the NSF, and in the travel section I put down 2 trips to Las Vegas ? 1 to Reno ? Maybe a couple to Monte Carlo for completeness ? And what about some legal fees when I get arrested for throwing roulette balls "vigorously"?
These are important questions ....
