Excuse me !
What’s that your saying … predicting the outcome of a dice throw.

Story highlights:
ScienceDaily (Sep. 12, 2012) — “Vegas, Monte Carlo, and Atlantic City draw people from around the world who are willing to throw the dice and take their chances. Researchers from the Technical University of Lodz, Poland, have spotted something predictable in the seemingly random throw of the dice.

By applying chaos theory and some high school level mechanics, they determined that by knowing the initial conditions – such as the viscosity of the air, the acceleration of gravity, and the friction of the table – it should be possible to predict the outcome when rolling the dice …..“

If only we played craps on flat, frictionless tables instead of actual craps tables...

Quote: Tomasz Kapitaniak

However, he quickly added, "friction is important."

With a high-friction table, in which the dice can't slide across very easily, the dice tend to bounce around more times, tumbling and twirling, and making the results harder to predict. With a smooth, low-friction, or soft table, the dice tend to bounce fewer times.

Even bouncing doesn't always mix things up. The high-speed video showed that dice frequently did not change their face even after a bounce.

Are Poles big gamblers?
"Baccarat is a game whereby the croupier gathers in money with a flexible sculling oar, then rakes it home. If I could have borrowed his oar I would have stayed." Mark Twain

I don't know if they are big gamblers but they are big mathematicians although on this question I expect various physicists will be "poles" apart.
