A decade later, in 2002, a large manufacturer of card-shuffling machines for casinos summoned Diaconis to determine whether their new automated shufflers truly randomized the deck. (They didn't.)

  I saw him talk about this. It was fascinating, especially when you consider that the problem is computationally very hard. The number of "shuffles" (permutations of a 52-card deck) exceeds the number of atoms in our galaxy, so it's impossible to build a computer with that much memory.

A biography about magician-turned-mathematician (probabilist) Persi Diaconis as well as a look at his experiments to understand the bias of a coin flip.

Great article. Everything I've been saying about Diaconis I learned through oral tradition. It's good to know I was pretty much right on.

Funny, after reading the article I concluded that you must've either read this article or a similar biographical sketch. Diaconis must be some legend! One of my favorite parts was that he was a bit 'rough' at one point. Gives the rest of us some hope!

shared by Matthew Leingang on 08 Jul 09 - Cached

the second Earl of Yarborough offered an interesting bet to his whist-playing friends: a thousand to one against them picking up a hand with no card above a nine. Mathematics was on his side since the odds are 1,827 to 1. There is no record that he ever paid off.

Unfortunately, the rest of the column is full of bridge jargon and I don't play. This is like NASCAR for nerds.

Although I did not enter the debate, I remember the Marilyn vos Savant vs. the mathematicians episode. I was in high school at the time. Marilyn's solution is sound, and her tactics are indeed wise: to people who disagreed with her explanation, she suggested they simply experiment and see what they find. So both the Bayesian and frequency models of probability are brought into play here. Persi Diaconis, the carnival card shark turned Harvard mathematics professor who I mentioned in class, is also quoted in this article. The Marilyn vs. the Mathematicians rematch did not turn out so well for her. When Wiles and Taylor finally proved Fermat's Last Theorem, she pronounced it phony because she didn't understand it. The mathematical consensus remains that the proof is good.

  I think royal flush is just another name for a straight flush that consists of the face cards. It's not usually distinghuished from other straight flushes. But it is the least probable hand!
