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.)

Illustrating Bertrand's Paradox with GeoGebra | Matthew Leingang - 0 views

Bertrand's Paradox is a question in continuous probability that shows the perils of uniformly distributed variables. The question is simple: given a random chord in a circle, what's the probability that it's longer than the side length of an equilateral triangle inscribed in that circle?

What's the length of a random chord in a circle? It turns out that even if you try to distribute the chord uniformly there is an ambiguity.

I pulled this up from the MIT Open CourseWare page under their Problem Solving class. I think they use problems of this caliber to prepare for the Putnam exam. - ...2 more comments...

OK, I now know two ways to solve this. The first way was along the lines you described in the break to me, Sam. It makes more sense than I originally thought, and with your Discrete Math knowhow you might be able to solve it. There's also a clever way, which I admit I didn't figure out until I solved it the other way.

That's a great list of problems btw!

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!

How Bayes's Theorem can be used to decide if mail is spam or not.

Very cool. Now that we see that mail filter software "adapts" to the user, we can address the problem in class of what would happen if a doctor who deals with prostate issues uses a filter and words such as viagra prop up when the email is not actually spam.

Far More Than You Ever Wanted To Know about where this formula comes from.

Stirling's approximation is for n! in terms of continuous functions.

The derivation didn't require any complex analysis after all; thank goodness.
